Spine J 2024; 24:1571-1594. [PMID: 38908439 DOI: 10.1016/j.spinee.2024.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 04/16/2024] [Accepted: 05/15/2024] [Indexed: 06/24/2024]
Abstract
BACKGROUND Current protocols on cervical immobilization postcervical spine fracture are widely accepted in the acute rehabilitation of older adults, however consensus on its overall effectiveness remains lacking. PURPOSE Summarize information from original studies on available cervical immobilization protocols following a cervical fracture and to answer the questions; Which types of study designs have been used to assess the effectiveness of these protocols? What are the currently reported cervical immobilization protocols following cervical fracture in adults? What is the effectiveness of these protocols? What adverse events are associated with these protocols? STUDY DESIGN Scoping review was performed. PATIENT SAMPLE Searches were performed on the following online databases from inception to February 23, 2023: EMBASE, MEDLINE, CINAHL, and CENTRAL. Databases were searched for articles pertaining to collar use post cervical spine fracture. OUTCOME MEASURES Effectiveness of the cervical fracture immobilization protocols was the primary outcome, examined by various measures including union rates and disability indexes. METHODS 4 databases were searched; EMBASE, MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Cochrane Central Register of Controlled Trials (CENTRAL) beginning on February 23, 2023, where 5,127 studies were yielded and 32 were extracted based on studies of adults (≥18 years) with a diagnosis of a cervical fracture (C0-C7) managed with a rigid external orthosis to prevent instability and surgery (collar, or cervicothoracic orthosis). Risk of bias was assessed using the guidelines set out by the Joanna Briggs Institute. RESULTS This scoping review yielded low-level prospective (18%) and retrospective (69%) cohort studies, case-control studies (3%), and case series (6%) from 1987 to 2022, patient age ranged from 14 to 104 years. Findings were difficult to summarize based on the lack of randomized controlled trials, leading to no clear conclusions drawn on the presence of standardized cervical immobilization protocols with no information on the duration of treatment or transition in care. Most included articles were retrospective cohort studies of poor to moderate quality, which have significant risk of bias for intervention questions. The effectiveness of these protocols remains unclear as most studies evaluated heterogeneous outcomes and did not present between-group differences. Mortality, musculoskeletal (MSK) complications, and delayed surgery were common adverse events associated with cervical collar use. CONCLUSION This scoping review highlights the need for higher levels of evidence as there is currently no standardized immobilization protocol for cervical spine fractures as a primary treatment, the effectiveness of cervical immobilization protocols is unclear, and mortality, MSK complications, and delayed surgery are common adverse events. No sources of funding were used for this scoping review.

Posterior atlantoaxial fixation of osteoporotic odontoid fracture: biomechanical analysis of the Magerl versus harms techniques in a cadaver model. Spine J 2024; 24:1510-1516. [PMID: 38685273 DOI: 10.1016/j.spinee.2024.04.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 04/09/2024] [Accepted: 04/22/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND CONTEXT Odontoid fractures are among the most common cervical spine fractures in the elderly and are associated with increased morbidity and mortality. Clinical evidence suggests improved survival and quality of life after operative intervention compared to nonoperative treatment. PURPOSE This study seeks to examine the stability of an osteoporotic Type II odontoid fracture following posterior atlantoaxial fixation with either the Magerl transarticular fixation technique or the Harms C1 lateral mass screws C2 pedicle screw rod fixation. STUDY DESIGN Biomechanical cadaveric study. METHODS Eighteen cadaveric specimens extending from the cephalus to C7 were used in this study. Reflective marker arrays were attached to C1 and C2 and a single marker on the dens to measure movement of each during loading with C2-C3 and occiput-C1 being allowed to move freely. A biomechanical testing protocol imparted moments in flexion-extension, axial rotation, and lateral bending while a motion capture system recorded the motions of C1, C2, and the dens. The spines were instrumented with either the Harms fixation (n=9) or Magerl fixation (n=9) techniques, and a simulated Type II odontoid fracture was created. Motions of each instrumented spine were recorded for all moments, and then again after the instrumentation was removed to model the injured, noninstrumented state. RESULTS Both Harms and Magerl posterior C1-C2 fixation allowed for C1, C2, and the dens to move as a relative unit. Without fixation the dens motion was coupled with C1. No significant differences were found in X, Y, Z translation motion of the dens, C1 or C2 during neutral zone motions between the Magerl and Harms fixation techniques. There were no significant differences found in Euler angle motion between the two techniques in either flexion-extension, axial rotation, or lateral bending motion. CONCLUSIONS Our findings suggest that both Harms and Magerl fixation can significantly reduce dens motion in Type II odontoid fractures in an osteoporotic cadaveric bone model. CLINICAL SIGNIFICANCE Both Harms and Magerl posterior atlantoaxial fixation techniques allowed for C1, C2, and the dens to move as a relative unit following odontoid fracture, establishing more anatomic stability to the upper cervical spine.

Abstract
BACKGROUND The incidence of odontoid fractures among the elderly population has been increasing in recent years. Elderly individuals with dementia may be at increased risk for inferior outcomes following such fractures. Although surgical intervention has been maintained to optimize survival and recovery, it is unclear if this benefit extends to patients with dementia. We hypothesized that patients with dementia who were treated operatively for odontoid fractures would experience improved survival and lower rates of hospice admission but higher rates of delirium and of intensive interventions. METHODS We used Medicare claims data (2017 to 2018) to identify community-dwelling individuals with dementia who sustained type-II odontoid fractures. We considered treatment strategy (operative or nonoperative) as the primary predictor and survival as the primary outcome. The secondary outcomes consisted of post-treatment delirium, hospice admission, post-treatment intensive intervention, and post-discharge admission to a nursing home or a skilled nursing facility. In all models, we controlled for age, biological sex, race, Elixhauser Comorbidity Index, Frailty Index, admission source, treating hospital, and dual eligibility. Adjusted analyses for survival were conducted using Cox proportional hazards regression. Adjusted analyses for secondary outcomes were performed using generalized estimating equations. To address confounding by indication, we performed confirmatory analyses using inverse probability of treatment weighting. RESULTS In this study, we included 1,030 patients. The median age of the cohort was 86.5 years (interquartile range, 80.9 to 90.8 years), 60.7% of the patients were female, and 90% of the patients were White. A surgical procedure was performed in 19.8% of the cohort. Following an adjusted analysis, patients treated surgically had a 28% lower hazard of mortality (hazard ratio, 0.72 [95% confidence interval (CI), 0.53 to 0.98]), but higher odds of delirium (odds ratio, 1.64 [95% CI, 1.10 to 2.44]). These findings were preserved in the inverse probability weighted analysis. CONCLUSIONS We found that, among individuals with dementia who sustain a type-II odontoid fracture, surgical intervention may confer a survival benefit. A surgical procedure may be an appropriate treatment strategy for individuals with dementia whose life-care goals include life prolongation and maximizing quality of life in the short term following an injury.

Abstract
BACKGROUND Cervical spine fractures are associated with high mortality in elderly patients. This study aims to identify patient-related and in-hospital factors contributing to this mortality. METHODS A 3-year retrospective study of 235 patients aged 65+ presenting with cervical spine fractures was performed. Age cohorts were 65-74, 75-84, and 85+ years. Mortality was measured at 30, 90, 180 and 365-days post-discharge. RESULTS Mortality was 11 %, 15 %, 19 %, and 22 % at 30-, 90-, 180- and 365-days respectively. Surgery and fracture pattern was not associated with mortality (p = 0.37; p = 0.28). Charlson Comorbidity Index (p < 0.001; hazard ratio [HR] = 1.3), functional dependency (p < 0.001; HR = 2.5) and delirium (p < 0.001; HR = 8.9) were associated with mortality between 0 and 365 days post-discharge. CONCLUSIONS Mortality in cervical spine fractures is associated with CCI and delirium, but not associated with operative management or fracture pattern. This suggests the need for careful consideration in patient selection for cervical spine procedures and aggressive inpatient delirium management.

Abstract
BACKGROUND The incidence of cervical spine fractures is increasing every day, causing a huge burden on society. This study aimed to develop and verify a nomogram to predict the in-hospital mortality of patients with cervical spine fractures without spinal cord injury. This could help clinicians understand the clinical outcome of such patients at an early stage and make appropriate decisions to improve their prognosis. METHODS This study included 394 patients with cervical spine fractures from the Medical Information Mart for Intensive Care III database, and 40 clinical indicators of each patient on the first day of admission to the intensive care unit were collected. The independent risk factors were screened using the Least Absolute Shrinkage and Selection Operator regression analysis method, a multi-factor logistic regression model was established, nomograms were developed, and internal validation was performed. A receiver operating characteristic (ROC) curve was drawn, and the area under the ROC curve (AUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated to evaluate the discrimination of the model. Moreover, the consistency between the actual probability and predicted probability was reflected using the calibration curve and Hosmer-Lemeshow (HL) test. A decision curve analysis (DCA) was performed, and the nomogram was compared with the scoring system commonly used in clinical practice to evaluate the clinical net benefit. RESULTS The nomogram indicators included the systolic blood pressure, oxygen saturation, respiratory rate, bicarbonate, and simplified acute physiology score (SAPS) II. The results showed that our model had satisfactory predictive ability, with an AUC of 0.907 (95% confidence interval [CI] = 0.853-0.961) and 0.856 (95% CI = 0.746-0.967) in the training set and validation set, respectively. Compared with the SAPS-II system, the NRI values of the training and validation sets of our model were 0.543 (95% CI = 0.147-0.940) and 0.784 (95% CI = 0.282-1.286), respectively. The IDI values of the training and validation sets were 0.064 (95% CI = 0.004-0.123; P = 0.037) and 0.103 (95% CI = 0.002-0.203; P = 0.046), respectively. The calibration plot and HL test results confirmed that our model prediction results showed good agreement with the actual results, where the HL test values of the training and validation sets were P = 0.8 and P = 0.95, respectively. The DCA curve revealed that our model had better clinical net benefit than the SAPS-II system. CONCLUSION We explored the in-hospital mortality of patients with cervical spine fractures without spinal cord injury and constructed a nomogram to predict their prognosis. This could help doctors assess the patient's status and implement interventions to improve prognosis accordingly.

Risk factors for in-hospital mortality in geriatric patients aged 80 and older with axis fractures: a nationwide, cross-sectional analysis of concomitant injuries, comorbidities, and treatment strategies in 10,077 cases. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024; 33:185-197. [PMID: 37714928 DOI: 10.1007/s00586-023-07919-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 05/05/2023] [Accepted: 08/23/2023] [Indexed: 09/17/2023]
Abstract
PURPOSE To investigate the association between treatment, comorbidities, concomitant injuries, and procedures with in-hospital mortality in patients aged 80 years or older with axis fractures. METHODS Data were extracted from the German InEK (Institut für das Entgeltsystem im Krankenhaus) GmbH database (2019-2021) for patients aged 80 years or older with axis fractures and the in-hospital mortality rate was calculated. Differences in comorbidities and concomitant diseases and injuries were analyzed using the Chi-square test. In surgically treated patients, odds ratios (OR) with 95% confidence intervals (95% CI) were used to analyze potential risk factors for in-hospital mortality. RESULTS Among 10,077 patients, the in-hospital mortality rate was 8.4%, with no significant difference between surgically (9.4%) and non-surgically treated patients (7.9%; p = 0.103). The most common comorbidities were essential hypertension (67.3%), atrial fibrillation (28.2%), and chronic kidney disease (23.3%), while the most common concomitant injuries were head and face wounds (25.9%), concussions (12.8%), and atlas fractures (11.6%). In surgically treated patients, spinal cord injury (OR = 4.62, 95% CI: 2.23-9.58), acute renal failure (OR = 3.20, 95% CI: 2.26-4.53), and acute bleeding anemia (OR = 2.06, 95% CI: 1.64-2.59) were associated with increased in-hospital mortality (all p < 0.01). Screw-rod-system fixation of one segment (OR = 0.74, 95% CI: 0.56-0.97) and intraoperative navigation (OR = 0.45, 95% CI: 0.16-0.71) were identified as potential protective factors (both p < 0.05). CONCLUSION Comprehensive geriatric assessment and optimization of comorbidities during treatment are crucial. The indication for surgical treatment must be carefully individualized. Future studies should focus on the choice of surgical technique, perioperative blood management, and intraoperative navigation as potential protective factors.

Spine J 2024; 24:107-117. [PMID: 37683769 DOI: 10.1016/j.spinee.2023.08.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 08/16/2023] [Accepted: 08/29/2023] [Indexed: 09/10/2023]
Abstract
BACKGROUND CONTEXT Socioeconomic status (SES) has been associated with differential healthcare outcomes and may be proxied using the area-deprivation index (ADI). Few studies to date have investigated the role of ADI on patient-reported outcomes and clinically meaningful improvement following lumbar spine fusion surgery. PURPOSE The purpose of this study is to investigate the role of SES on lumbar fusion outcomes using Patient-Reported Outcomes Measurement Information System (PROMIS) surveys. STUDY DESIGN/SETTING Retrospective review of a single institution cohort. PATIENT SAMPLE About 205 patients who underwent elective one-to-three level posterior lumbar spine fusion. OUTCOME MEASURES Change in PROMIS scores and achievement of minimum clinically important difference (MCID). METHODS Patients 18 years or older undergoing elective one-to-three level lumbar spine fusion secondary to spinal degeneration from January 2015 to September 2021 with minimum one year follow-up were reviewed. ADI was calculated using patient-supplied addresses and patients were grouped into quartiles. Higher ADI values represent worse deprivation. Minimum clinically important difference (MCID) thresholds were calculated using distribution-based methods. Analysis of variance testing was used to assess differences within and between the quartile cohorts. Multivariable regression was used to identify features associated with the achievement of MCID. RESULTS About 205 patients met inclusion and exclusion criteria. The average age of our cohort was 66±12 years. The average time to final follow-up was 23±8 months (range 12-36 months). No differences were observed between preoperative baseline scores amongst the four quartiles. All ADI cohorts showed significant improvement for pain interference (PI) at final follow-up (p<.05), with patients who had the lowest socioeconomic status having the lowest absolute improvement from preoperative baseline physical function (PF) and PI (p=.01). Only those patients who were in the lowest socioeconomic quartile failed to significantly improve for PF at final follow-up (p=.19). There was a significant negative correlation between socioeconomic level and the absolute proportion of patients reaching MCID for PI (p=.04) and PF (p=.03). However, while ADI was a significant predictor of achieving MCID for PI (p=.02), it was nonsignificant for achieving MCID for PF. CONCLUSIONS Our study investigated the influence of ADI on postoperative PROMIS scores and identified a negative correlation between ADI quartile and the proportion of patients reaching MCID. Patients in the worse ADI quartile had lower chances of reaching clinically meaningful improvement in PI. Policies focused on alleviating geographical deprivation may augment clinical outcomes following lumbar surgery.

Clinical outcome of surgical management of mild cervical compressive myelopathy based on minimum clinically important difference. Spine J 2024; 24:68-77. [PMID: 37660898 DOI: 10.1016/j.spinee.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/31/2023] [Accepted: 08/29/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND CONTEXT Cervical compressive myelopathy (CCM), caused by cervical spondylosis (cervical spondylotic myelopathy [CSM]) or ossification of the posterior longitudinal ligament (OPLL), is a common neurological disorder in the elderly. For moderate/severe CCM, surgical management has been the first-line therapeutic option. Recently, surgical management is also recommended for mild CCM, and a few studies have reported the surgical outcome for this clinical population. Nonetheless, the present knowledge is insufficient to determine the specific surgical outcome of mild CCM. PURPOSE To examine the surgical outcomes of mild CCM while considering the minimum clinically important difference (MCID). STUDY DESIGN Retrospective study. PATIENT SAMPLE Patients who underwent subaxial cervical surgery for CCM caused by CSM and OPLL between 2013 and 2022 were enrolled. OUTCOME MEASURES The Japanese Orthopedic Association score (JOA score) was employed as the clinical outcomes. Based on previous reports, the JOA score threshold to determine mild myelopathic symptoms was set at ≥14.5 points, and the MCID of the JOA score for mild CCM was set at 1 point. METHODS The patients with a JOA score of ≥14.5 points at baseline were stratified into the mild CCM and were examined while considering the MCID. The mild CCM cohort was dichotomized into the improvement group, including the patients with an achieved MCID (JOA score ≥1 point) or with a JOA score of 17 points (full mark) at 1 year postoperatively, and the nonimprovement group, including the others. Demographics, symptomatology, radiographic findings, and surgical procedure were compared between the two groups and studied using the receiver operating characteristic (ROC) curve. RESULTS Of 335 patients with CCM, 43 were stratified into the mild CCM cohort (mean age, 58.5 years; 62.8% male). Among them, 25 (58.1 %) patients were assigned to the improvement group and 18 (41.9 %) were assigned to the nonimprovement group. The improvement group was significantly younger than the nonimprovement group; however, other variables did not significantly differ. ROC curve analysis showed that the optimal cutoff point of the patient's age to discriminate between the improvement and nonimprovement groups was 58 years with an area under the curve of 0.702 (p=.015). CONCLUSIONS In the present study, the majority of patients with mild CCM experienced improvement reaching the MCID of JOA score at 1 year postoperatively. The present study suggests that for younger patients with mild CCM, especially those aged below 58 years, subjective neurological recovery is more likely to be obtained. Meanwhile, the surgery takes on a more prophylactic significance to halt disease progression for older patients. The results of this study can help in the decision-making process for this clinical population.

Abstract
BACKGROUND Operating rooms (ORs) are one of the costliest units in a hospital, therefore the cumulative consequences of any kind of inefficiency in OR management lead to a significant loss of revenue for the hospital, staff dissatisfaction, and patient care disruption. One of the possible solutions to improving OR efficiency is knowing a reliable estimate of the duration of operations. The literature suggests that the current methods used in hospitals, e.g., a surgeon's estimate for the given surgery or taking the average of only five previous records of the same procedure, have room for improvement. METHODS We used over 4 years of elective surgery records (n = 52,171) from one of the major metropolitan hospitals in Australia. We developed robust Machine Learning (ML) approaches to provide a more accurate prediction of operation duration, especially in the absence of surgeon's estimation. Individual patient characteristics and historic surgery information attributed to medical records were used to train predictive models. A wide range of algorithms such as Extreme Gradient Boosting (XGBoost) and Random Forest (RF) were tested for predicting operation duration. RESULTS The results show that the XGBoost model provided statistically significantly less error than other compared ML models. The XGBoost model also reduced the total absolute error by 6854 min (i.e., about 114 h) compared to the current hospital methods. CONCLUSION The results indicate the potential of using ML methods for reaching a more accurate estimation of operation duration compared to current methods used in the hospital. In addition, using a set of realistic features in the ML models that are available at the point of OR scheduling enabled the potential deployment of the proposed approach.

Abstract
INTRODUCTION Comorbidities are significant patient factors that contribute to outcomes after surgery. There is highly variable collection of this information across the literature. To help guide the systematic collection of best practice data, the Australian Spine Registry conducted an evidence map to investigate (i) what comorbidities are collected by spine registries, (ii) how they are collected and (iii) the compliance and completeness in collecting comorbidity data. METHOD A literature search was performed to identify published studies of adult spine registry data reporting comorbidities. In addition, targeted questionnaires were sent to existing global spine registries to identify the maximum number of relevant results to build the evidence map. RESULTS Thirty-six full-text studies met the inclusion criteria. There was substantial variation in the reporting of comorbidity data; 55% of studies reported comorbidity collection, but only 25% reported the data collection method and 20% reported use of a comorbidity index. The variation in the literature was confirmed with responses from 50% of the invited registries (7/14). Of seven, three use a recognised comorbidity index and the extent and methods of comorbidity collection varied by registry. CONCLUSION This evidence map identified variations in the methodology, data points and reporting of comorbidity collection in studies using spine registry data, with no consistent approach. A standardised set of comorbidities and data collection methods would encourage collaboration and data comparisons between patient cohorts and could facilitate improved patient outcomes following spine surgery by allowing data comparisons and predictive modelling of risk factors.

Abstract
Background Though there is ongoing controversy regarding the best treatment option for cervical spine dislocation (CSD), anterior cervical surgery with direct decompression is becoming widely accepted. However, managing all cases of subaxial CSD entirely by a single anterior approach is rarely seen in the published literature. Methods The study comprised patients with subaxial CSD who underwent surgical stabilization utilizing a single anterior approach. Most of the CSD was reduced and anterior cervical discectomy and fusion (ACDF) were performed. Anterior cervical corpectomy and fusion (ACCF) were done in unreduced dislocations. The patient's neurological condition, radiological findings, and functional outcomes were assessed. SPSS version 25.0 (IBM Corp., Armonk, NY) was used for statistical analysis. Results The total number of operated cases was 64, with an average of 42 months of follow-up. The mean age was 34.50±11.92 years. The most prevalent level of injury was C5/C6 (57.7%). Reduction was achieved in 92.2% of cases; only 7.8% of patients needed corpectomy. The typical operative time was 84.25±9.55 minutes, with an average blood loss of 112.12±25.27 ml. All cases except complete spinal cord injury (CSI) were improved neurologically (87.63%). The mean Neck Disability Index (NDI) was 11.14±11.43, and the pre-operative mean visual analog score (VAS) was finally improved to 2.05±0.98 (P<0.05). In all cases, fusion was achieved. The most common complication was transient dysphagia (23.4%). After surgery, no patient developed or aggravated a neurological impairment. Implant failure was not observed at the final follow-up except for two cases where screws were pulled out partially. Conclusion Based on the results of this study, a single anterior approach is a safe and effective procedure for subaxial CSD treatment with favorable radiological, neurological, and functional outcomes.

Complications, readmissions, reoperations and patient-reported outcomes in patients with multiple sclerosis undergoing elective spine surgery - a propensity matched analysis. Spine J 2022; 22:1820-1829. [PMID: 35779839 DOI: 10.1016/j.spinee.2022.06.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 06/05/2022] [Accepted: 06/16/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Multiple sclerosis (MS) is an autoimmune, neurodegenerative disease that can lead to significant functional disability. Improving treatment regimens have extended life expectancy and led to an increase in the number of elective spine surgeries for degenerative conditions in the MS population. Recent literature has reported mixed results regarding the efficacy of elective spine surgery for patients with MS. There is also a paucity of literature comparing postoperative patient reported outcomes (PROs) and reoperation rates between patients with and without MS. PURPOSE To determine if patients with MS have worse PROs and higher complication, readmission and reoperation rates after elective spine surgery compared with patients without neurodegenerative conditions when adjusting for baseline covariates through propensity matching. STUDY DESIGN/SETTING Retrospective review of prospectively collected data from the Quality Outcomes Database (QOD), a national, longitudinal, multicenter spine outcomes registry. PATIENT SAMPLE For the lumbar cohort, 312 patients with MS and 46,738 patients without MS were included. The cervical myelopathy cohort included 91 patients with MS and 6,426 patients without MS. The cervical radiculopathy cohort consisted of 103 patients with MS and 13,751 patients without MS. OUTCOME MEASURES 1) complication rates, 2) readmission rates, 3) reoperation rates, and 4) PROs at 3- and 12-months including ODI/NDI, NRS back/neck/arm/leg pain, mJOA scores and patient satisfaction ratings. METHODS Data from the QOD was queried for patients with surgeries occurring between 04/2013-01/2019. Three surgical groups were included: 1) Elective lumbar surgery, 2) Elective cervical surgery for myelopathy, 3) Elective cervical surgery for radiculopathy. Patients with any neurodegenerative condition other than MS were excluded. Patients without MS were propensity matched against patients with MS in a 5 to 1 ratio without replacement based on ASA grade, arthrodesis, surgical approach, number of operated levels, age, and baseline ODI/NDI, NRS leg/arm pain, NRS back/neck pain, and EQ-5D. Multivariable regressions with cluster-robust standard errors were used to estimate average effect of how the outcome would change if the MS patient didn't have the disease. The mean difference was used for continuous outcomes and the risk difference was used for binary outcomes. RESULTS For the lumbar cohort, no differences were found between the 2 groups at 3 or 12 months in any of the outcome measures. For the myelopathy cohort, patients with MS patients had a lower rate of reoperation at 12 months (risk difference=-0.036, p=.007) and worse 3-month mJOA scores (mean difference=-1.044, p=.004) compared with patients without MS. For the radiculopathy cohort, patients with MS had a lower rate of reoperation at 3 months (risk difference=-0.019, p=.018) and 12 months (risk difference=-0.029, p=.007) compared with those without MS. CONCLUSIONS Patients with MS had similar PROs compared with patients without MS when adjusting for baseline covariates through propensity matching, except for 3-month mJOA scores in the myelopathy cohort. Reoperation rates were found to be lower in patients with MS undergoing elective cervical surgery for both myelopathy and radiculopathy. These results suggest that when analyzed independently, a diagnosis of MS does not significantly impact complication, readmission and reoperation rates or PROs, and therefore should not represent a major contraindication to elective spine surgery. Surgical decisions in this patient population should be made based on careful consideration of patient factors including other comorbidities as well as baseline patient functional status.

Abstract
BACKGROUND Although the mortality related to hip fracture and osteoporotic vertebral fracture have been reported, few studies have examined the mortality related to atlas and/or axis fractures. The aim of this study was to assess the association between mortality and atlas and/or axis fractures retrospectively and to elucidate the efficacy of surgical treatment. METHODS A total of 33 elderly patients who were treated for atlas and/or axis fractures at our institution between January 2012 and December 2018 were included in this study. These patients were divided into two groups: surgical treatment and conservative treatment. Fracture types, comorbidities, neurological status, treatment types, and walking ability at follow-up were reviewed. Mortality was assessed using medical records or via phone interviews. RESULTS The mean age at injury was 79.9 ± 8.0 years, and the mean follow-up period was 2.3 years. The overall mortality rates at 1 and 5 years were 21.4% and 48.4%, respectively. During the observation period, 12 (36%) patients died. Twenty-two patients were treated conservatively (14 were treated with a cervical collar, 8 were treated with a halo vest). Surgical procedures included occipital-cervical fixation, osteosynthesis of C2 fractures, C1-2 fixation, and C1-4 fixation using a posterior approach. Surgical treatment correlated with better survival rates. There was no significant difference between the two groups in terms of ambulatory ability and functional recovery. CONCLUSION Upper cervical spine fractures appear to have a worse prognosis compared to hip and osteoporotic vertebral fractures. This study indicates the efficacy of surgical treatment for upper cervical spine fractures in the elderly for improving survival prognosis.

Abstract
Background
The 1-year mortality and functional prognoses of patients who received surgery for cervical trauma in the elderly remains unclear. The aim of this study is to investigate the rates of, and factors associated with mortality and the deterioration in walking capacity occurring 1 year after spinal fusion surgery for cervical fractures in patients 65 years of age or older.
Methods
Three hundred thirteen patients aged 65 years or more with a traumatic cervical fracture who received spinal fusion surgery were enrolled. The patients were divided into a survival group and a mortality group, or a maintained walking capacity group and a deteriorated walking capacity group. We compared patients’ backgrounds, trauma, and surgical parameters between the two groups. To identify factors associated with mortality or a deteriorated walking capacity 1 year postoperatively, a multivariate logistic regression analysis was conducted.
Results
One year postoperatively, the rate of mortality was 8%. A higher Charlson comorbidity index (CCI) score, a more severe the American Spinal Cord Injury Association impairment scale (AIS), and longer surgical time were identified as independent factors associated with an increase in 1-year mortality. The rate of deterioration in walking capacity between pre-trauma and 1 year postoperatively was 33%. A more severe AIS, lower albumin (Alb) and hemoglobin (Hb) values, and a larger number of fused segments were identified as independent factors associated with the increased risk of deteriorated walking capacity 1 year postoperatively.
Conclusions
The 1-year rate of mortality after spinal fusion surgery for cervical fracture in patients 65 years of age or older was 8%, and its associated factors were a higher CCI score, a more severe AIS, and a longer surgical time. The rate of deterioration in walking capacity was 33%, and its associated factors were a more severe AIS, lower Alb, lower Hb values, and a larger number of fused segments.

Abstract
STUDY DESIGN Retrospective analysis on prospectively collected data. OBJECTIVE The aim of this study was to construct a clinical prediction model for 90-day mortality in elderly patients with traumatic spine injuries. SUMMARY OF BACKGROUND DATA Spine trauma in the elderly population is increasing. Comparing elderly spine trauma patients to younger patients with similar injuries proves challenging due to the extensive comorbidities and frailty found in the elderly. There is a paucity of evidence to predict survival of elderly patients following traumatic spinal injuries. METHODS All patients 65+ with spine trauma presenting to a level I trauma center from 2010 to 2019 were reviewed from a prospectively maintained trauma registry. Retrospective chart review was performed to record injury, frailty scores, comorbidities, presence of spinal cord injury, imaging evidence of sarcopenia and osteopenia, mortality, and complications. We preselected 13 variables for our multivariable logistic regression model: hypotension on admission, gender, marital status, age, max Abbreviated Injury Scale, Modified Frailty Index, surgical treatment, hematocrit, white blood count, spinal cord injury, closed head injury, injury level and presence of high energy mechanism. The performance of the prediction model was evaluated using a concordance index and calibration plot. The model was internally validated via bootstrap approach. RESULTS Over the 9-year period, 1746 patients met inclusion criteria; 359 (20.6%) patients died within 90 days after presenting with spine trauma. The most important predictors for 90-day mortality were age, hypotension, closed head injury, max Abbreviated Injury Scale and hematocrit. There was an optimism-corrected C-index of 0.77. A calculator was created to predict a personalized mortality risk. CONCLUSION The incidence of spine trauma in elderly patients continues to increase. Previous publications described preexisting conditions that imply increased mortality, but ours is the first to develop a predictive calculator. Prospective research is planned to externally validate this model to better determine its predictive value and utility in the clinical setting.

Abstract
Background Odontoid process fractures are among the most common in elderly cervical spines. Their treatment often requires fixation, which may include use of implants anteriorly or posteriorly. Bone density can significantly affect the outcomes of these procedures. Currently, little is known about bone mineral density (BMD) distributions within cervical spine in elderly. This study documented BMD distribution across various anatomical regions of elderly cervical vertebrae. Methods and findings Twenty-three human cadaveric C1-C5 spine segments (14 males and 9 female, 74±9.3 y.o.) were imaged via quantitative CT-scan. Using an established experimental protocol, the three-dimensional shapes of the vertebrae were reconstructed from CT images and partitioned in bone regions (4 regions for C1, 14 regions for C2 and 12 regions for C3-5). The BMD was calculated from the Hounsfield units via calibration phantom. For each vertebral level, effects of gender and anatomical bone region on BMD distribution were investigated via pertinent statistical tools. Data trends suggested that BMD was higher in female vertebrae when compared to male ones. In C1, the highest BMD was found in the posterior portion of the bone. In C2, BMD at the dens was the highest, followed by lamina and spinous process, and the posterior aspect of the vertebral body. In C3-5, lateral masses, lamina, and spinous processes were characterized by the largest values of BMD, followed by the posterior vertebral body. Conclusions The higher BMD values characterizing the posterior aspects of vertebrae suggest that, in the elderly, posterior surgical approaches may offer a better fixation quality.

Abstract
PURPOSE To assess the complications and mortality in elderly individuals with cervical spine injuries. METHODS This retrospective observational study was conducted in a tertiary care hospital in a rural area in Japan. Data sets from the trauma registry (January 2011 to March 2018) were analyzed. Patients with cervical spine injury were divided into those aged ≥ 65 years (group Y) and > 65 years (group E). We then analyzed age, sex, 30-day mortality, hospital stay, level of cervical spine injury, presence of cervical vertebral fracture, perioperative complications (pneumonia, urinary tract infection, and severe bedsore), neurological deficit (Frankel classification), Abbreviated Injury Scale (AIS) score, and Injury Severity Score (ISS). RESULTS We evaluated a total of 398 patients; among them, 177 were included in group Y and 221 in group E. The assessed parameters were as follows: age (group Y/E; 48.7/75.9 years), men (78.0/72.3%), 30-day mortality (8.5/10.0%, p = 0.159), hospital stay (17.2/19.1 days, p = 0.36), level of cervical spine injury (C1 [5.7/4.5%], C2 [12.4/15.8%], C3 [10.2/17.2%], C4 [14.1/16.3%], C5 [26.6/22.2%], C6 [22.0/12.2%], and C7 [11.3/10.9%]), vertebral fracture (56.6/61.9%), central cord syndrome (36.2/33%), operation (18.6/13.1%), pneumonia (6.8/11.8%, p = 0.077), urinary tract infection (4.0/6.3%, p = 0.26), severe bedsore (0/1.8%, p = 0.068), Frankel classification (grade A [5.7/6.3%], grade B [6.8/7.7%], grade C [24.9/28.5%], grade D [17.5/11.8%], and grade E [34.5/33.9%]), mean AIS score in the cervical spine (3.3/3.5, p = 0.04), and mean ISS (23.2/22.2, p = 0.38). C3 injuries tended to be higher in group E. CONCLUSION Mortality and morbidity associated with cervical spine injuries did not differ between younger and older patients. Nevertheless, vigilance is required for the detection of C3 injury in elderly individuals.

Abstract
Background Cervical fractures are potentially serious and can have fatal consequences if not treated properly. Correct diagnosis and classification of injury is the first step in determining the most appropriate treatment. Cervical fractures will have an impact on the patient’s work, and COVID-19 is a challenge in the hospital to treat a cervical fracture. This study aims to discuss the case of patients with cervical fractures that have undergone surgical treatment in the COVID-19 pandemic. Case Presentation Two cases of emergency patients with cervical injury treated at the hospital in the acute setting of the COVID-19 pandemic. All these patients experienced delayed timing to arrive in the emergency department of Prof. Dr. R. Soeharso Orthopedic Hospital. Neurological outcome was assessed before being discharged after surgery and a 3-month follow-up post-surgery. Results Laminectomy and posterior stabilization and fusion (PSF) were performed immediately after diagnosis was established in both patients. Physical rehabilitation was performed. In a 3-month follow-up, both patients’ neurological functions improved. Conclusion Clinical outcomes of cervical injury patients can be affected by some factors, for example, timing to diagnosis, timing to traction application, timing to surgery, and timing to rehabilitation. Depending on the institution, weekend days can also affect the delay of the COVID-19 PCR swab. MRI schedule and patient optimal condition can also affect the timing to surgery. The immediate diagnosis and prompt treatment are needed to make a better outcome, especially better neurological status.

Abstract
Background and purpose - Few studies have reported the mortality rate after skeletal fractures involving different locations, within the same population. We analyzed the 30-day and 1-year mortality rates following different fractures.Patients and methods - We included 295,713 fractures encountered in patients 16-108 years of age, registered in the Swedish Fracture Register (SFR) from 2012 to 2018. Mortality rates were obtained by linkage of the SFR to the Swedish Tax Agency population register. The standardized mortality ratios (SMR) at 30 days and 1 year were calculated for fractures in any location and for each of 27 fracture locations, using age- and sex-life tables from Statistics Sweden (www.scb.se).Results - The overall SMR at 30 days was 6.8 (95% CI 6.7-7.0) and at 1 year 2.2 (CI 2.2-2.2). The SMR was > 2 for 19/27 and 13/27 of the fracture locations at 30 days and 1 year, respectively. Humerus, femur, and tibial diaphysis fractures were all associated with high SMR, at both 30 days and 1 year.Interpretation - Patients sustaining a fracture had approximately a 7-fold increased mortality at 30 days and over 2-fold increased mortality at 1 year as compared with what would be expected in the general population. High mortality rates were seen for patients with axial skeletal and proximal extremity fractures, indicating frailty in these patient groups.

Abstract
PURPOSE To identify the independent risk factors for adverse outcomes and determine the effect of L5-S1 involvement on the outcome of surgical treatment of lumbar pyogenic spondylitis (PS). METHODS A retrospective analysis was performed for all consecutive patients who underwent surgery for lumbar PS between November 2004 and June 2020 at a single institution. The patients were divided into two groups based on the outcomes: good and adverse (treatment failure, relapse, or death). Treatment failure was defined as persistent or worsening pain with C-reactive protein (CRP) reduction less than 25% from preoperative measurement or requiring additional debridement. Relapse was defined as the reappearance of symptoms and signs with an elevated white blood cell count, erythrocyte sedimentation rate, and CRP after the first period of treatment. Binary logistic regression analyses were performed to identify the independent risk factors for adverse outcomes. RESULTS Twenty-four (21.2%) of the 113 patients were classified as having adverse outcomes: treatment failure, relapse, and death occurred in 15, 7, and 2 patients, respectively. The involvement of L5-S1 (adjusted odds ratio [aOR] = 6.561, P = 0.004), Methicillin-resistant Staphylococcus aureus (MRSA) infection (aOR = 6.870, P = 0.008), polymicrobial infection (aOR = 12.210, P = 0.022), and Charlson comorbidity index (CCI; P = 0.005) were identified as significant risk factors for adverse outcomes. CONCLUSION Involvement of L5-S1, MRSA, polymicrobial infection, and CCI were identified as independent risk factors for adverse outcomes after surgical treatment of lumbar PS. Because L5-S1 is anatomically demanding to access anteriorly, judicious access and thorough debridement are recommended in patients requiring anterior debridement of L5-S1.

Abstract
BACKGROUND Lumbar disc arthroplasty (LDA) has emerged as a motion-sparing alternative to lumbar fusion. Although LDA may be amenable to the ambulatory surgical setting, to date no study has identified the factors predisposing patients to extended hospital stay. METHODS A national surgical quality improvement database was queried from 2011 to 2019 for patients undergoing elective, single-level, primary LDA. Univariate and multivariate logistic regression analyses were performed to elucidate predictors of length of stay (LOS) at or above the 90th percentile of the study population (3 days). Secondary study endpoints included rates of complications, as well as predictors and reasons for unplanned reoperation within 30 days. RESULTS A total of 630 patients met eligibility criteria for the study, of whom 517 (82.1%) had LOS <3 days and 113 (17.9%) had LOS ≥3 days. Multivariate logistic regression revealed associations between prolonged hospitalization and postoperative diagnosis of degenerative disk disease, obesity, Hispanic identity, and operation length >120 minutes. Before discharge, patients with LOS ≥3 days were more likely to have venous thromboembolisms, pneumonia, surgical site infections, and reoperations. Independent predictors of reoperation were wound infections, diabetes, and smoking. CONCLUSIONS Complications following elective single-level LDA are relatively rare, with few extended hospitalizations being attributable to any specific complication. Risk factors for prolonged LOS appear to be related to diagnosis and surgical time rather than to modifiable preoperative comorbidities. Conversely, unplanned reoperations within 30 days are associated with optimizable perioperative factors such as smoking, diabetes, and surgical site infection.

Abstract
Patients admitted with a cervical fracture are twice as likely to die within 30 days of injury than those with a hip fracture. However, guidelines for the management of cervical fractures are less available than for hip fractures. We hypothesise that outcomes may differ between these types of fractures. We analysed 1359 patients (406 men, 953 women) with mean age of 83.8 years (standard deviation = 8.7) admitted to a National Health Service hospital in 2013-2019 with a cervical (7.5%) or hip fracture (92.5%) of similar age. The association of cervical fracture (hip fracture as reference), hospital length of stay (LOS), co-morbidities, age and sex with outcomes (acute delirium, new pressure ulcer, and discharge to residential/nursing care) was assessed by stepwise multivariate logistic regression. Acute delirium without history of dementia was increased with cervical fractures: odds ratio (OR) = 2.4, 95% confidence interval (CI) = 1.3-4.7, age ≥ 80 years: OR = 3.5 (95% CI = 1.9-6.4), history of stroke: OR = 1.8 (95% CI = 1.0-3.1) and ischaemic heart disease: OR = 1.9 (95% CI = 1.1-3.6); pressure ulcers was increased with cervical fractures: OR = 10.9 (95% CI = 5.3-22.7), LOS of 2-3 weeks: OR = 3.0 (95% CI = 1.2-7.5) and LOS of ≥ 3 weeks: OR = 4.9, 95% CI = 2.2-11.0; and discharge to residential/nursing care was increased with cervical fractures: OR = 3.2 (95% CI = 1.4-7.0), LOS of ≥ 3 weeks: OR = 4.4 (95% CI = 2.5-7.6), dementia: OR = 2.7 (95% CI = 1.6-4.7), Parkinson's disease: OR = 3.4 (95% CI = 1.3-8.8), and age ≥ 80 years: OR = 2.7 (95% CI = 1.3-5.6). In conclusion, compared with hip fracture, cervical fracture is more likely to associate with acute delirium and pressure ulcers, and for discharge to residency of high level of care, independent of established risk factors.

Variability and contributions to cost associated with anterior versus posterior approaches to lumbar interbody fusion. Clin Neurol Neurosurg 2021; 206:106688.

Abstract
OBJECTIVE Lumbar interbody fusions are being performed with increased frequency in the last decade. Anterior and posterior interbody techniques have demonstrated relatively similar success rates. Nonetheless, despite increased attention to cost-effective care delivery, approach-related differences in procedural cost and predictors for these differences remain poorly defined. The purpose of this investigation was to characterize the variability in cost for anterior versus posterior-based lumbar interbody fusions and to identify key predictors of procedural cost. METHODS We evaluated the records of all patients who underwent a primary anterior (ALIF) or posterior/transforaminal (PLIF/TLIF) lumbar interbody fusion with concomitant posterior fusion from 2016 to 2020 at four hospitals in a major metropolitan area. We reviewed the records of all included patients and abstracted demographics, insurance status, approach, operative time, diagnosis, surgeon, institution, open versus minimally invasive technique, and components of procedural costs. Costs based upon interbody approach were compared via multivariable adjusted analyses using negative binomial regression. RESULTS We included 139 interbody fusion procedures; 98 were performed via posterior approach (TLIF/PLIF) and 41 using an anterior approach. Anterior techniques were associated with significantly increased costs as compared to posterior procedures (anterior, $16316 [SE 556] vs. posterior, $9415 [SE 345]; p < 0.001). This determination remained significant following multivariable adjusted analysis (regression coefficient -0.22, 95% CI -0.34, -0.10, p < 0.001). Multivariable analysis also indicated that surgeon, invasiveness, and procedure time were significant predictors of total cost. CONCLUSION Our findings demonstrate that anterior interbody techniques are, on average, 173% (anterior, $16316 [SE 556] vs. posterior, $9415 [SE 345]; p < 0.001) more expensive than posterior-based procedures. Given the relative equipoise of these different approaches for many clinical applications, these findings should be considered in an ecosystem increasingly attentive to cost effective care delivery. This work has also provided specific procedural variables for surgeons and systems to target when optimizing procedural costs.

Abstract
Background In several previous studies, Charlson comorbidity index (CCI) score was associated with postoperative complications, mortality, and re-admission. There are few reports about the influence of CCI score on postoperative clinical outcome. The purpose of this study was to investigate the influence of comorbidities as calculated with CCI on postoperative clinical outcomes after PLIF. Methods Three hundred sixty-six patients who underwent an elective primary single-level PLIF were included. Postoperative clinical outcome was evaluated with the Japanese Orthopaedic Association lumbar score (JOA score). The correlation coefficient between the CCI score and postoperative improvement in JOA score was investigated. Patients were divided into three groups according to their CCI score (0, 1, and 2+). JOA improvement rate, length of stay (LOS), and direct cost were compared between each group. Postoperative complications were also investigated. Results There was a weak negative relationship between CCI score and JOA improvement rate (r = − 0.20). LOS and direct cost had almost no correlation with CCI score. The JOA improvement rate of group 0 and group 1 was significantly higher than group 2+. LOS and direct cost were also significantly different between group 0 and group 2+. There were 14 postoperative complications. Adverse postoperative complications were equivalently distributed in each group, and not associated with the number of comorbidities. Conclusions A higher CCI score leads to a poor postoperative outcome. The recovery rate of patients with two or more comorbidities was significantly higher than in patients without comorbidities. However, the CCI score did not influence LOS and increased direct costs. The surgeon must take into consideration the patient’s comorbidities when planning a surgical intervention in order to achieve a good clinical outcome.

Abstract
BACKGROUND C1-C2 injury represents 25-40% of cervical injuries and predominantly occurs in the geriatric population. METHODS A prospective multicentre study was conducted under the aegis of the french spine surgery society (SFCR) investigating the impact of age, comorbidities, lesion type, and treatment option on mortality, complications, and fusion rates. RESULTS A total of 417 patients were recruited from 11 participating centres. The mean ± SD age was 66.6 ± 22 years, and there were 228 men (55%); 5.4% presented a neurological deficit at initial presentation. The most frequent traumatic lesion was C2 fracture (n = 308). Overall mortality was 8.4%; it was 2.3% among those aged ≤ 60 years, 5.0% 61-80 years, and 16.0% > 80 years (p < 0.001). Regarding complications, 17.8% of patients ≤ 70 years of age presented with ≥ 1 complication versus 32.3% > 70 years (p = 0.0009). The type of fracture did not condition the onset of complications and/or mortality (p > 0.05). The presence of a comorbidity was associated with a risk factor for both death (p = 0.0001) and general complication (p = 0.008). Age and comorbidities were found to be independently associated with death (p < 0.005). The frequency of pseudoarthrosis ranged from 0 to 12.5% up to 70 years of age and then constantly and progressively increased to reach 58.6% after 90 years of age. CONCLUSIONS C1-C2 injury represents a serious concern, possibly life-threatening, especially in the elderly. We found a major impact of age and comorbidities on mortality, complications, and pseudarthrosis; injury pattern or treatment option seem to have a minimal effect.

Abstract
Introduction The world is seeing a growth of the aging population and the number of surgical treatments in this age group which is also true for spinal conditions. The greatest increase in spinal fusion surgery has been observed in patients aged 65 years and above. Only a few works of literature were available on the issue, especially in India. Materials and Methods An observational study in which 70 patients aged 70 years and above who underwent spinal surgery for degenerative and traumatic spinal injury, from January 2013 to July 2017 in the neurosurgery department of a single institute, were reviewed. Around 53 patients were assessed for disability/functional outcome and their health-related quality of life (HRQOL) using the Oswestry disability index (ODI) and RAND 36-item health survey 1.0 scoring method (SF-36) comparing the preoperative and postoperative status. Result The mean age was 74.19 years (range 70-91 years). Laminectomy-19 (27.14%) was the most common surgical procedure performed. Overall there were nine (12.85%) major complications with mortality of five (7.14%) patients. There was a significant reduction of crippled patients (14-9, P = 0.009) in the ODI score. SF-36: There was significant improvement in degenerative patient (P = 0.000 to P = 0.012). In traumatic patient, only pain had significant improvement (P = 0.045). Conclusion This study showed that the age of the patient should not be the limiting factor for the surgical management of a patient with a degenerative or a traumatic spinal condition.

Abstract
BACKGROUND Fall-induced injuries in older adults are a major public health challenge. METHODS We determined the current trends in the number and age-adjusted incidence of fall-induced severe cervical spine injuries among older adults in Finland by taking into account all persons 50 years of age or older who were admitted to Finnish hospitals for primary treatment of these injuries between 1970 and 2017. Similar patients aged 20-49 years served as a reference group. RESULTS The annual number of fall-induced severe cervical spine injuries among older Finnish adults rose steeply during the follow-up, from 59 in 1970 to 502 in 2017. The age-adjusted incidence of injury (per 100,000 persons) was higher in men than women throughout this period and showed a clear increase from 1970 to 2017: from 8.4 to 25.0 in men, and from 2.8 to 13.9 in women. In both sexes, the increase was most prominent in the oldest age group, persons aged 80 years or older. In the reference group, the injury incidence declined by time. CONCLUSIONS The number and incidence of fall-induced severe cervical spine injuries among older Finns showed a sharp rise between 1970 and 2017. An increase in the average risk of serious falls may partly explain the phenomenon. Effective fall and injury prevention measures are urgently needed since further aging of the population is likely to aggravate the problem in the near future.

Can the Charlson Comorbidity Index be used to predict the ASA grade in patients undergoing spine surgery? EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2020; 29:2941-2952. [PMID: 32945963 DOI: 10.1007/s00586-020-06595-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 08/17/2020] [Accepted: 09/05/2020] [Indexed: 01/05/2023]
Abstract
BACKGROUND The American Society of Anaesthesiologists' Physical Status Score (ASA) is a key variable in predictor models of surgical outcome and "appropriate use criteria". However, at the time when such tools are being used in decision-making, the ASA rating is typically unknown. We evaluated whether the ASA class could be predicted statistically from Charlson Comorbidy Index (CCI) scores and simple demographic variables. METHODS Using established algorithms, the CCI was calculated from the ICD-10 comorbidity codes of 11'523 spine surgery patients (62.3 ± 14.6y) who also had anaesthetist-assigned ASA scores. These were randomly split into training (N = 8078) and test (N = 3445) samples. A logistic regression model was built based on the training sample and used to predict ASA scores for the test sample and for temporal (N = 341) and external validation (N = 171) samples. RESULTS In a simple model with just CCI predicting ASA, receiver operating characteristics (ROC) analysis revealed a cut-off of CCI ≥ 1 discriminated best between being ASA ≥ 3 versus < 3 (area under the curve (AUC), 0.70 ± 0.01, 95%CI,0.82-0.84). Multiple logistic regression analyses including age, sex, smoking, and BMI in addition to CCI gave better predictions of ASA (Nagelkerke's pseudo-R2 for predicting ASA class 1 to 4, 46.6%; for predicting ASA ≥ 3 vs. < 3, 37.5%). AUCs for discriminating ASA ≥ 3 versus < 3 from multiple logistic regression were 0.83 ± 0.01 (95%CI, 0.82-0.84) for the training sample and 0.82 ± 0.01 (95%CI, 0.81-0.84), 0.85 ± 0.02 (95%CI, 0.80-0.89), and 0.77 ± 0.04 (95%CI,0.69-0.84) for the test, temporal and external validation samples, respectively. Calibration was adequate in all validation samples. CONCLUSIONS It was possible to predict ASA from CCI. In a simple model, CCI ≥ 1 best distinguished between ASA ≥ 3 and < 3. For a more precise prediction, regression algorithms were created based on CCI and simple demographic variables obtainable from patient interview. The availability of such algorithms may widen the utility of decision aids that rely on the ASA, where the latter is not readily available.

Abstract
OBJECTIVES/HYPOTHESIS Despite being common, neck injuries have received relatively little attention for important quality of care metrics. This study sought to determine the association between blunt and penetrating neck injuries on mortality and length of stay, and to identify additional patient and hospital-level characteristics that impact these outcomes. STUDY DESIGN Retrospective cohort study utilizing the American College of Surgeons Trauma Quality Improvement Program database. METHODS Adult patients (≥18) who sustained traumatic injuries involving the soft tissues of the neck between 2012 and 2016 were eligible. Multiple imputation was used to account for missing data. Logistic regression and negative binomial models were used to analyze 1) in-hospital mortality and 2) length of stay respectively while adjusting for potential confounders and accounting for clustering at the hospital level. RESULTS In a cohort of 20,285 patients, the crude mortality rate was lower in those sustaining blunt neck injuries compared to penetrating injuries (4.9% vs. 6.0%, P < .01), while length of hospital stay was similar (median 9.9 vs. 10.2, P = 0.06). In adjusted analysis, blunt neck injuries were associated with a reduced odds of mortality during hospital admission (odds ratio: 0.66, 95% confidence intervals [0.564, 0.788]), as well as significant reductions in length of stay (rate ratio: 0.92, 95% confidence intervals [0.880, 0.954]). CONCLUSIONS Blunt neck injuries are associated with lower mortality and length of stay compared to penetrating injuries. Areas of future study have been identified, including elucidation of processes of care in specific organs of injury. LEVEL OF EVIDENCE Level 3 Laryngoscope, 131:E1109-E1116, 2021.

Abstract
OBJECTIVES To understand the prognostic value of laboratory markers at presentation on post-treatment survival of patients 50 and older following cervical spine fracture. PATIENTS AND METHODS We obtained clinical data on patients 50 and older treated for cervical spine fracture in a single healthcare system (2006-2016). Our primary outcome consisted of 1-year mortality, with mortality within 3-months of presentation considered secondarily. Our primary predictors included serum glucose, serum creatinine, platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) at presentation. We used multivariable logistic regression to adjust for confounding from sociodemographic and clinical characteristics. Point estimates and 95 % confidence intervals (CI) from the final model were refined using Bayesian regression techniques. RESULTS We included 1781 patients in this analysis, with an average age of 75.3 (SD 12.0). The mortality rate at 3-months was 12 % and 17 % at 1-year. In multivariable testing, neither elevated PLR or NLR were significant predictors of 1-year mortality. Elevated serum creatinine was associated with increased mortality at 1-year (OR 1.89; 95 % CI 1.30, 2.74), as was hyperglycemia (OR 1.50; 95 % CI 1.06, 2.13). Elevated serum creatinine remained influential (OR 1.64; 95 % CI 1.06, 2.54) on mortality at 3-months. CONCLUSIONS This is the first study to evaluate laboratory values at presentation in conjunction with survival following cervical fractures. The results can be used to help forecast natural history and in expectation management. They may also help formulate treatment plans, especially when the need for surgical intervention is not clearly defined.

Abstract
INTRODUCTION In older patients with axis fractures, the survival benefit from surgery is unclear due to high baseline mortality. Comparative effectiveness research can provide evidence from population level cohorts. Propensity weighting is the preferred methodology for reducing bias when analyzing national administrative cohort data for these purposes but has not yet been utilized for this important surgical conundrum. We estimate the effect of surgery on mortality after isolated acute traumatic axis fracture in older adults. MATERIALS AND METHODS We used a retrospective population-based cohort of Medicare patients and generated a propensity score-weighted nonsurgical cohort and compared mortality with and without surgery. This balanced the comorbid conditions of the treatment groups. Incident fractures were defined using a predetermined algorithm based on enrollment, code timing, and billing location. The primary outcome was adjusted all-cause 1-year mortality. RESULTS From 12 372 beneficiaries with 1-year continuous enrollment and a coded axis fracture, 2676 patients met final inclusion/exclusion criteria. Estimated incidence was 16.5 per 100 000 person-years overall in 2014 (95% confidence interval [CI]: 15.0-18.0) and was stable from 2008 through 2014. Patients with axis fracture had a mean age of 82.8 years, 30.2% were male, and 91.9% were Caucasian. Mortality was 3.8 times higher (CI 3.6-4.1) compared with the general population of older US adults. Propensity-weighted mortality at 1 year for nonsurgical patients was 26.7 of 100 (CI: 24.5-29.0). Mortality for surgical patients was significantly lower (19.7/100; CI 14.5-25.0). Risk difference was 7.0 fewer surgical deaths per 100 patients (CI: 1.3-12.7). Surgical patients aged 65 to 74 years had the largest difference in mortality with 11.2 fewer deaths per 100 (CI: 1.1-21.3). DISCUSSION Patients with axis fractures are predominantly older Caucasian women and have a higher mortality rate than the general population. Propensity-weighted mortality at 1-year was lower in the surgical patients with the largest risk difference occurring in patients 65 to 74 years old. CONCLUSIONS Surgery may provide an independent survival benefit in patients aged 65 to 75 years, and the mortality difference diminishes thereafter.

Abstract
BACKGROUND It is unclear whether surgery or conservative treatment is more suitable for elderly patients with type II and type III odontoid fractures. We performed this meta-analysis to compare the efficacy of surgical and conservative treatments for type II and type III odontoid fractures. METHODS A literature search was performed in PubMed, Embase, Web of Science, and Cochrane Library in January 2017. Only articles comparing surgery with conservative treatment in elderly patients with type II and type III odontoid fractures were selected. After 2 authors independently assessed the retrieved studies, 18 articles were included in this meta-analysis, and the primary endpoints were the nonunion rate and mortality rate. The secondary outcomes were patient satisfaction, complications, and the length of the hospital stay. The quality of the included studies was evaluated using the modified Newcastle-Ottawa scale. Sensitivity analyses were performed for high-quality studies, and the publication bias was evaluated using a funnel plot. RESULTS Lower nonunion (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.18-0.40, P < .05) and mortality rates (OR: 0.52, 95% CI: 0.34-0.79, P < .05) confirmed the superiority of surgery in treating type II and type III fractures. The secondary outcomes differed. Patients in the surgery group felt more satisfied with the outcome (OR: 3.44, 95% CI: 1.19-9.95, P < .05), and the complications were similar in the 2 groups (OR: 1.14, 95% CI: 0.78-1.68, P = .5), whereas patients in conservative groups spent less time in the hospital (OR: 5.10, 95% CI: 2.73-7.47, P < .05). The results of the subgroup analyses and sensitivity analysis were similar to the original outcomes, and no obvious publication bias was observed in the funnel plot. CONCLUSION Most elderly (younger than 70 years) patients with type II or type III odontoid fractures should be considered candidates for surgical treatment, due to the higher union rate and lower mortality rate, while statistically significant differences were not observed in the population with an advanced age (older than 70 years). Therefore, the selection of the therapeutic approach for elderly patients with odontoid fractures requires further exploration. Simultaneously, based on our meta-analysis, a posterior arthrodesis treatment was significantly superior to the anterior odontoid screw treatment.

Do Medicare Accountable Care Organizations Reduce Disparities After Spinal Fracture? J Surg Res 2019; 246:123-130. [PMID: 31569034 DOI: 10.1016/j.jss.2019.09.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2019] [Revised: 08/19/2019] [Accepted: 09/05/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND National changes in health care disparities within the setting of trauma care have not been examined within Accountable Care Organizations (ACOs) or non-ACOs. We sought to examine the impact of ACOs on post-treatment outcomes (in-hospital mortality, 90-day complications, and readmissions), as well as surgical intervention among whites and nonwhites treated for spinal fractures. MATERIALS AND METHODS We identified all beneficiaries treated for spinal fractures between 2009 and 2014 using national Medicare fee for service claims data. Claims were used to identify sociodemographic and clinical criteria, receipt of surgery and in-hospital mortality, 90-day complications, and readmissions. Multivariable logistic regression analysis accounting for all confounders was used to determine the effect of race/ethnicity on outcomes. Nonwhites were compared with whites treated in non-ACOs between 2009 and 2011 as the referent. RESULTS We identified 245,704 patients who were treated for spinal fractures. Two percent of the cohort received care in an ACO, whereas 7% were nonwhite. We found that disparities in the use of surgical fixation for spinal fractures were present in non-ACOs over the period 2009-2014 but did not exist in the context of care provided through ACOs (odds ratio [OR] 0.75; 95% confidence interval [CI] 0.44, 1.28). A disparity in the development of complications existed for nonwhites in non-ACOs (OR 1.09; 95% CI 1.01, 1.17) that was not encountered among nonwhites receiving care in ACOs (OR 1.32; 95% CI 0.90, 1.95). An existing disparity in readmission rates for nonwhites in ACOs over 2009-2011 (OR 1.34; 95% CI 1.01, 1.80) was eliminated in the period 2012-2014 (OR 0.85; 95% CI 0.65, 1.09). CONCLUSIONS Our work reinforces the idea that ACOs could improve health care disparities among nonwhites. There is also the potential that as ACOs become more familiar with care integration and streamlined delivery of services, further improvements in disparities could be realized.

Predicting survival in older patients treated for cervical spine fractures: development of a clinical survival score. Spine J 2019; 19:1490-1497. [PMID: 31125694 DOI: 10.1016/j.spinee.2019.03.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2018] [Revised: 03/01/2019] [Accepted: 03/01/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Emerging literature has identified the importance of pretreatment health and functional status as influential in the prognostication of survival. A comprehensive, accessible, predictive model for survival following cervical spine fracture has yet to be developed. PURPOSE To develop an accessible and intuitive predictive model for survival in individuals aged 50 and older treated for cervical spine fractures. STUDY DESIGN Retrospective review of records from two tertiary care centers (2009-2016). PATIENT SAMPLE Patients age 50 and older who received operative or nonoperative management for cervical fractures. OUTCOME MEASURES One-year mortality was the primary outcome with 3-month and 2-year mortality considered secondarily. METHODS Multivariable logistic regression was used to identify factors independently associated with mortality. The magnitude and precision of the relationship with 1-year mortality for statistically significant variables determined weighting in the scoring system subsequently developed. Score performance was tested through multivariable regression and bootstrap simulation. In a sensitivity test, the performance of the score developed for 1-year mortality was assessed using figures for the 3-month and 2-year time-points. RESULTS We included 1,758 patients. Mortality rates were 12% at 3 months, 17% at 1 year, and 21% at 2 years. Following multivariable testing age, injury severity score and Glasgow coma scale demonstrated the strongest predictive values for a base score, followed by serum albumin and ambulatory status. The resultant composite score ranged from 0 (base score≤4, albumin≤3.5 g/dL, and dependent/nonambulator at presentation) to a maximum of 4 (base score≥5, albumin>3.5 g/dL, and independent ambulator at presentation). Following multivariable analysis, when compared to patients with a score of 4, significantly increased odds of 1-year mortality were appreciated for those with scores of 3 (odds ratio [OR] 7.35; 95% confidence interval [CI] 3.77, 14.32), 2 (OR 8.43; 95% CI 4.66, 15.25), 1 (OR 17.47; 95% CI 9.81, 31.11), and 0 (OR 26.58; 95% CI 13.87, 50.92). Score performance was unchanged in bootstrap testing and sensitivity analyses. CONCLUSIONS We have developed a useful prognostic utility capable of informing survival in individuals age 50 and older, following cervical spine fractures. The score can be applied to adjust patient expectations, anticipate outcomes, and as an adjunct to decision-making in the postinjury period.

Abstract
INTRODUCTION/PURPOSE Though spinal fractures constitute a minority of all traumas, the financial burden imposed is immense especially following cervical spine trauma. There have been several papers in the past describing the incidence of cervical spine fractures. In this paper, we report the incidence of cervical spine fractures and correlate with demographic information and cause of injury and review the mechanism of fractures. MATERIALS AND METHODS We performed retrospective analysis of 934 patients who had undergone CT scan for cervical spine trauma at our institute which includes 16 hospitals and one level I trauma center over a period of 2 years. This list was created from a wider database of 13,512 patients imaged for suspected cervical spine injury. All patients who had at least one positive finding on CT were included in this study irrespective of any demographic difference. Each patient was analyzed by reviewing the medical records, and correlation was sought between demographics and cause of injury. RESULTS In our study, the peak incidence of cervical spine trauma was in the age group of 21-30 years followed by 31-40 years with a male:female ratio of 2.1. The major cause of injury in the study population was motor vehicle accidents (66.1%), followed by fall from height of less than 8 ft (12.2%). With regard to the ethnic distribution, Caucasians (46.9%) constituted the major population followed by Hispanic population (23.3%). C1 and C2 were observed to be more frequently fractured as compared with the subaxial spine. Incidence of C2 fractures (188 levels) was higher as compared with C1 (102 levels). Incidence of body and lateral mass fractures was marginally higher as compared with odontoid fractures. C7 (50 levels) was the most fractured vertebral body in the subaxial spine followed by C6 (35 levels) and C5. CONCLUSION Spinal trauma is on the rise and it helps to know the factors which can guide us for better management of these patients. We can utilize these results to prognosticate and streamline clinical management of these patients.

Abstract
BACKGROUND CONTEXT Accountable Care Organizations (ACOs) were designed to reduce healthcare costs while simultaneously improving quality. Given that the success of ACOs is predicated on controlling costs, concerns have been expressed that patients could be adversely affected through restricted access to surgery, including in the context of spine fracture care. PURPOSE Evaluate the impact of Medicare ACO formation on the utilization of surgery and outcomes following spinal fractures. STUDY DESIGN Retrospective review of Medicare claims (2009-2014). PATIENT SAMPLE Patients treated for spinal fractures in an ACO or non-ACO. OUTCOME MEASURES The utilization of surgery as treatment for spinal fractures, in-hospital mortality, 90-day complications, or hospital readmission within 90-days injury. METHODS We used a pre-post study design to compare outcomes for patients treated in ACOs versus non-ACOs. Receipt of surgery for treatment of a spinal fracture was the primary outcome, with mortality, complications and readmissions treated secondarily. We used multivariable logistic regression adjusting for confounders to determine the association between environment of care (ACO vs. non-ACO) and the outcomes of interest. In all testing, beneficiaries treated in non-ACOs during 2009 to 2011 were used as the referent. RESULTS During 2009 to 2011, 9% (n=10,866) of patients treated in non-ACOs received surgery, whereas a similar percentage (9%; n=210) underwent surgery in ACOs. This figure decreased to 8% (n=9,857) for individuals treated in non-ACOs over 2012 to 2014, although the surgical rate remained unchanged for those receiving care in an ACO (9%; n=227). There was no difference in the use of surgery among patients treated in ACOs (OR 0.96; 95% CI 0.79, 1.18) over 2012 to 2014. Similar increases in the odds of mortality were observed for both ACOs and non-ACOs during this period. A marginal, yet significant increase in complications was observed among ACOs, although there was no change in the odds of readmission. CONCLUSIONS Our study found that the formation of ACOs did not result in alterations in the use of surgery for spinal fractures or substantive changes in outcomes. As ACOs continue to evolve, more emphasis should be placed on the incorporation of measures directly related to surgical and trauma care in the determinants of risk-based reimbursements.

Abstract
BACKGROUND Cervical spine immobilization, including cervical collars, has been recommended in most trauma guidelines. However, cervical spine immobilization can be associated with harm, and an increasing body of evidence has demonstrated associated complications. We hypothesized that older trauma patients placed in cervical collars for >24 hours were at greater risk of developing collar-related complications compared with those placed in cervical collars for ≤24 hours. METHODS We conducted a retrospective cohort study of injured patients without a fracture of the cervical vertebrae, aged ≥65 years, who had been placed in a cervical collar during the period from January 1, 2015 to December 31, 2015. The primary outcome was the composite of the in-hospital development of nosocomial pneumonia and collar-related pressure ulcers. RESULTS A total of 1154 patients had been treated with cervical collars during the study period, and 61 (5.1%) had developed collar-related complications. Male sex, a lower initial Glasgow Coma Scale score, a history of congestive heart failure, a history of chronic obstructive pulmonary disease or asthma, operative management, and longer hospital and intensive care unit lengths of stay demonstrated a univariable association with collar-related complications (P < 0.10), in addition to a duration in the collar for >24 hours. An independent association was found between collar duration >24 hours and the outcome of interest (adjusted odds ratio, 2.50; 95% confidence interval, 1.16-5.39; P = 0.02). CONCLUSIONS Among older patients without a cervical vertebral fracture, duration of cervical collar use for >24 hours was associated with the development of collar-related complications. We recommend attention to early collar clearance for older trauma patients.

Abstract
Study Design Retrospective cohort study. Purpose The aim of this study was to identify features associated with increased mortality risk in traumatic C2 fractures in the elderly, including measures of comorbidity and frailty. Overview of Literature C2 fractures in the elderly are of increasing relevance in the setting of an aging global population and have a high mortality rate. Previous analyzes of risk factors for mortality have not included the measures of comorbidity and/or frailty, and no local data have been reported to date. Methods This study comprises a retrospective review of 70 patients of age >65 years at Waikato Hospital, New Zealand with traumatic C2 fractures identified on computed tomography between 2010 and 2016. Demographic details, medical history, laboratory results on admission, mechanism of injury, and neurological status on presentation were recorded. Medical comorbidities were also detailed allowing calculation of the Charlson Comorbidity Index (CCI) and the modified Frailty Index (mFI). Results The most common mechanism of injury was a fall from standing height (n=52, 74.3%). Mortality rates were 14.3% (n=10) at day 30, and 35.7% (n=25) at 1 year. Bivariate analysis showed that both CCI and mFI correlated with 1-year mortality rates. Reduced albumin and hemoglobin levels were also associated with 30-day and 1-year mortality rates. Forward stepwise logistic regression models determined CCI and low hemoglobin as predictors of mortality within 30 days, whereas CCI, low albumin, increased age, and female gender predicted mortality at 1 year. Conclusions The CCI was a useful tool for predicting mortality at 1 year in the patient cohort. Other variables, including common laboratory markers, can also be used for risk stratification, to initiate timely multidisciplinary management, and prognostic counseling for patients and family members.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES To investigate the risk factors associated with tracheostomy after traumatic cervical spinal cord injury (CSCI) and to identify factors associated with decannulation in an aging population. SETTING Advanced critical care and emergency center in Yokohama, Japan. METHODS Sixty-five patients over 60 years with traumatic CSCI treated between January 2010 and June 2017 were enrolled. The parameters analyzed were age, sex, American Spinal Injury Association impairment scale score (AIS) at admission and one year after injury, neurological level of injury (NLI), injury mechanism, Charlson's comorbidity index (CCI), smoking history, radiological findings, intubation at arrival, treatment choice, length of intensive care unit (ICU) stay, tracheostomy rate, improvement of AIS, decannulation rate, and mortality after one year. RESULTS The study included 48 men (74%; mean age 72.8 ± 8.3 years). Twenty-two (34%), 10 (15%), 24 (37%), and 9 (14%) patients were classified as AIS A, B, C, and D, respectively. The tracheostomy group showed significantly more severe degree of paralysis, more patients with major fractures or dislocations, more operative treatment, longer ICU stay, poorer improvement in AIS score after one year and higher rate of intubation at arrival. AIS A at injury was the most significant risk factor for tracheostomy. The non-decannulation group had a significantly higher mortality. The risk factor for failure of decannulation was CCI. CONCLUSIONS Risk factors for tracheostomy after traumatic CSCI were AIS A, operative treatment, major fracture/dislocation, and intubation at arrival. The only factor for failure of decannulation was CCI.

Abstract
BACKGROUND Odontoid process fractures, of which type II constitute the majority, are an increasingly important cause of morbidity and mortality in the elderly population. The incidence of geriatric type II fractures is steadily increasing in line with the aging population. However, the decision between surgical and non-surgical intervention for type II fractures in the elderly remains controversial. PURPOSE The present study aims to synthesize the current published literature comparing outcomes following surgical and non-surgical interventions for type II odontoid fractures in the elderly population (≥65 years old). STUDY DESIGN/SETTING Systematic review and meta-analysis were performed. METHODS A systematic search of MEDLINE, MEDLINE In-Progress & Other Non-Indexed Citations, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed to identify available evidence in English language. Studies with extractable data for all type II odontoid fractures in participants aged 65 years or older and which compared surgical and non-surgical intervention were included. Methodological quality was assessed using the Downs & Black checklist. Primary outcomes were mortality at short-term follow-up (≤3 months), mortality at long-term follow-up (predetermined study endpoint or mean follow-up length), and radiological union rate. Funding was provided by The University of Edinburgh for travel expenses to present this paper at the Society of British Neurological Sciences 2016 Conference ($170). RESULTS Twelve studies (n=1,098), all non-randomized, met eligibility criteria. Methodological quality was particularly poor in the confounding, bias, and power domains of assessment. Substantial methodological and statistical heterogeneity allowed only a narrative synthesis of the primary outcomes. Overall, data on mortality at short-term follow-up appeared to favor neither surgical nor non-surgical intervention. A small favorable outcome in surgically managed patients over non-surgically managed patients in terms of mortality at long-term follow-up was not proven conclusive because of considerable heterogeneity in study methodologies. Inadequate reporting of the time point of union assessment introduced the potential for significant intra- and interstudy heterogeneity and precluded assessment of union rates. CONCLUSIONS Evidence on this controversial topic is sparse, markedly heterogeneous, and of poor quality. Well-designed prospective trials adhering to guidance published by the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative are required to inform clinical practice on this contentious but growing issue. Future randomized controlled trials should include an assessment of frailty and medical comorbidities with suitable patients subsequently randomized to surgical or non-surgical treatment.

Abstract
BACKGROUND Advanced-imaging screening for asymptomatic blunt cerebrovascular injury is controversial. Vertebral artery injury (VAI) is most commonly associated with cervical spine fracture, and many guidelines advocate indiscriminate screening for all cervical spine fractures. The purpose of this study was to determine whether the addition of computed tomographic angiography (CTA) results in a change in management for patients with cervical spine fractures. METHODS Adult patients treated for acute cervical spine fractures after blunt trauma during the period of 2000 to 2015 were retrospectively identified. Patients who sustained a penetrating trauma or who had a history of neoplasm or prior cervical spine surgery were excluded. The following variables were recorded: age, biologic sex, race, medical comorbidities, Injury Severity Score (ISS), mechanism of injury, whether CTA of the neck was obtained in addition to computed tomography (CT), cervical spine fracture characteristics and treatment, and the presence of VAI. Recommendation for a change in management with antithrombotic therapy was the primary outcome measure. Detection of stroke and of VAI were secondary outcomes. Propensity-score matching was performed to negate the significant differences in baseline demographic and clinical characteristics. RESULTS A total of 3,943 patients were screened for eligibility, and 2,831 patients met the inclusion criteria. Propensity-score matching yielded 1 cohort who underwent CT + CTA and 1 cohort who underwent CT alone, both with 644 patients and equivalent demographic and clinical characteristics. CTA identified definite or indeterminate VAI in 113 patients, and for 62 patients, antithrombotic therapy was recommended. In the CT-alone cohort, VAI was identified in 11 patients incidentally through other imaging, and antithrombotic therapy was recommended for 8 patients. Two patients in the CT + CTA group had major adverse bleeding events as a result of the initiation of antithrombotic therapy. There were no preventable strokes in either group. CONCLUSIONS The addition of CTA increased detection of VAI and the recommendation for antithrombotic therapy. There were no preventable strokes in either cohort and 2 major adverse bleeding events attributable to the recommended pharmacologic antithrombotic therapy. Nonselective screening is not warranted and should be limited to a high-risk subset of patients. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
STUDY DESIGN Narrative review. OBJECTIVE To establish recommendations for the treatment of odontoid fractures based on current literature and the knowledge of the experts of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU). METHODS Narrative review of the literature. Analyzing treatment algorithms of German trauma and spine centers as members of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU). RESULTS There are many influencing factors leading to appropriate treatment of odontoid fractures such as age, bone quality, arthrosis, classification, and type of the fracture. Conservative nonoperative treatment is appropriate for stable undislocated displaced odontoid fractures. Anterior osteosynthesis with 1 or 2 screws leads to good results in the classical unstable type II odontoid fracture in patients with good bone quality. However, modifiers have been identified by the working group leading to higher complication and failure rates. For these cases, more stable constructs and/or posterior approaches are indicated. CONCLUSIONS Operation seems to be standard treatment for odontoid fractures. However, in the aged population, conservative treatment should be considered as morbidity and mortality rise significantly in the group of >75 years. Conservative treatment may also be started within stable nondislocated fractures, but then regular controls have to be performed. If operation is indicated, many influencing factors have to be considered for appropriate approach and technique. The classification of Anderson and D'Alonzo is still standard. To create an adequate treatment algorithm, dislocation displacement and instability have to be identified. Stable odontoid fractures are treated conservatively non-operatively, but if so regular controls have to be performed. Unstable and/or dislocated displaced odontoid fractures are treated by anterior osteosynthesis with 1 or 2 screws. The technique is demanding and leads to elevated complication and failure rates if modifiers are apparent. In these cases, posterior instrumentation or fusion of C1 and C2 is favorable. In the aged population (>80 years), operative therapy is critical as postoperative morbidity complication and mortality rates rise significantly. As there is still some bias in the treatment algorithms, the working group recommends establishment of a prospective study to result in more objective statements.

Abstract
Fractures of the C1 vertebrae (atlas) are commonly the result of falls and other trauma, which cause hyperextension, or axial compression of the cervical spine. Although historically thought as a benign injury with lower neurological risks, current data suggests that this may not hold true for geriatric patients (aged 65 y and older) who may be predisposed to these fractures even after lower-energy trauma such as ground-level falls. Advancements in orthopedic trauma care has increased our diagnostic abilities to identify and manage patients with C1 fractures and other upper cervical spine trauma. However, there are no universal treatment guidelines based on level I trials. Current treatment ranges from nonoperative to operative management depending on fracture-pattern and integrity of the surrounding ligaments. Furthermore, in the elderly patients these fractures present a unique dilemma due to preexisting comorbidities and contraindications to various treatment modalities. C1 fractures warrant greater recognition to provide optimal treatment to patients and minimize the risk for developing complications. The goal of this review is to highlight the most updated treatment guidelines and to discuss the complications of both operative and nonoperative management of C1 fractures especially among the elderly patient population.

Abstract
BACKGROUND CONTEXT Traumatic spinal injuries are often associated with both long-term disability, higher frequency of hospital readmissions, and high medical costs for individuals of all ages. Age differences in terms of injury profile and health outcomes among those who sustain a spinal cord injury have been identified. However, factors that may influence health outcomes among those with a spinal injury have not been extensively examined at a population level. PURPOSE The present study aims to describe the characteristics of traumatic spinal injury, identify factors predictive of mortality, and estimate the cost of hospital treatment for younger and older people. STUDY DESIGN/SETTING This is a population-based retrospective epidemiological study using linked hospitalization and mortality records during January 1, 2010 to June 30, 2014 in New South Wales, Australia. PATIENT SAMPLE The present study included 13,429 hospitalizations. OUTCOME MEASURES Mortality within 30 and 90 days of hospitalization, hospital length of stay (LOS), and hospitalization costs were determined. METHODS Hospitalizations with a principal diagnosis of spinal cord injury or spinal fractures were used to identify traumatic spinal injuries. Age-standardized incidence rates were calculated and negative binomial regression was used to examine statistical significant changes over time. Cox proportional hazard regression was used to examine the effect of risk factors on survival at 90 days. RESULTS There were 13,429 hospitalizations, with 52.4% of individuals aged ≥65 years. The hospitalization rates for individuals aged ≤64 and ≥65 years were both estimated to significantly increase per year by 3.3% (95% confidence interval [CI] 0.97-5.79, p<.006) and 3.3% (95% CI 1.02-5.71, p=.005), respectively. For individuals aged ≥65 years, there were a higher proportion of women injured, comorbid conditions, injuries after a fall in the home or aged care facility, a longer hospital LOS, unplanned hospital admissions, and deaths than individual aged ≤64 years. The average cost per index hospitalization was AUD$23,808 for individuals aged ≤64 years and AUD$31,187 for individuals aged ≥65 years with a total estimated cost of AUD$371 million. Mortality risk at 90 days was increased for individuals who had one or more comorbidities, a higher injury severity score, and if their injury occurred in the home or an aged care facility. CONCLUSIONS Spinal injury represents a substantial cost and results in debilitating injuries, particularly for older individuals. Spinal injury prevention efforts for older people should focus on the implementation of fall injury prevention, whereas for younger individuals, prevention measures should target road safety.

Abstract
STUDY DESIGN Adult patients who received computed tomography (CT) alone or CT-magnetic resonance imaging (MRI) for the evaluation of cervical spine injury. OBJECTIVE To evaluate the utility of CT-MRI in the diagnosis of cervical spine injury using propensity-matched techniques. SUMMARY OF BACKGROUND DATA The optimal evaluation (CT alone vs. CT and MRI) for patients with suspected cervical spine injury in the setting of blunt trauma remains controversial. METHODS The primary outcome was the identification of a cervical spine injury, with decision for surgery and change in management considered secondarily. A propensity score was developed based on the likelihood of receiving evaluation with CT-MRI, and this score was used to balance the cohorts and develop two groups of patients around whom there was a degree of clinical equipoise in terms of the imaging protocol. Logistic regression was used to evaluate for significant differences in injury detection in patients evaluated with CT alone as compared to those receiving CT-MRI. RESULTS Between 2007 and 2014, 8060 patients were evaluated using CT and 693 with CT-MRI. Following propensity-score matching, each cohort contained 668 patients. There were no significant differences between the two groups in baseline characteristics. The odds of identifying a cervical spine injury were significantly higher in the CT-MRI group, even after adjusting for prior injury recognition on CT (odds ratios 2.6; 95% confidence interval 1.7-4.0; P < 0.001). However, only 53/668 patients (8%) in the CT-MRI group had injuries identified on MRI not previously recognized by CT. Only a minority of these patients (n = 5/668, 1%) necessitated surgical intervention. CONCLUSION In this propensity-matched cohort, the addition of MRI to CT alone identified missed injuries at a rate of 8%. Only a minority of these were serious enough to warrant surgery. This speaks against the standard addition of MRI to CT-alone protocols in cervical spine evaluation after trauma. LEVEL OF EVIDENCE 3.
