Worsening ambulation in elderly patients with cervical odontoid fractures: A nationwide multicenter study in Japan. J Orthop Sci 2024; 29:927-932.

Abstract
BACKGROUND Despite the increasing prevalence of cervical odontoid fractures in older adults, the treatment strategy is controversial. The objectives of the current study are to investigate the prognosis and complications of cervical odontoid fractures in elderly patients and to identify factors associated with worsening of ambulation after 6 months. METHODS This multicenter, retrospective study included 167 patients aged 65 years or older with odontoid fractures. Patient demographic and treatment data were investigated and compared according to the treatment strategy. To determine associations with worsening ambulation after 6 months, we focused on the treatment strategies (nonsurgical treatment [collar immobilization or halo vest], conversion to surgery, or initial surgery) and patients' background. RESULTS Patients who received nonsurgical treatment were significantly older, and patients who underwent surgery had more Anderson-D'Alonzo type 2 fractures. Of the patients initially treated nonsurgically, 26% later underwent surgery. Numbers of complications, including death, and degrees of ambulation after 6 months did not differ significantly among treatment strategies. Patients who had worsened ambulation after 6 months were significantly more likely to be older than 80 years, to have needed assistance with walking before injury, and to have cerebrovascular disease. Multivariable analysis showed that a score of ≥2 on the 5-item modified frailty index (mFI-5) was significantly associated with worsening ambulation. CONCLUSIONS Preinjury mFI-5 scores of ≥2 were significantly associated with worsening ambulation 6 months after treatment of cervical odontoid fractures in older adults.

Abstract
STUDY DESIGN Single-center retrospective cohort study. OBJECTIVES Type II odontoid fractures occur disproportionately among elderly populations and cause significant morbidity and mortality. It is a matter of debate whether these injuries are best managed surgically or conservatively. Our goal was to identify how treatment modalities and patient characteristics correlated with functional outcome and mortality. METHODS We identified adult patients (>60 years) with traumatic type II odontoid fractures. We used multivariate regression controlling for patient demographics, Glasgow Coma Scale (GCS) score, Charlson Comorbidity Index (CCI), modified Rankin Scale (mRS) score, modified Frailty Index (mFI-5 and mFI-11), fracture displacement, and conservative vs operative treatment. RESULTS Of the 59 patients (mean age 77.9 years), 24 underwent surgical intervention and 35 underwent conservative management. Operatively managed patients were younger (73.4 vs 80.6 years, P < .001) and had higher degree of fracture displacement (3.5 vs 1.0 mm, P = .002) than conservatively managed patients but no other differences in baseline characteristics. Twenty-four patients (40.7%) died within the study period (median time to death: 376 days). There were no differences between treatment groups in functional outcomes (mRS or Frankel Grade) or mortality (33.3% in operative group vs 45.7%, P = .34). There was a statistically significant correlation between higher presentation mRS score and subsequent mortality on multivariate analysis (OR = 2.06, 95% CI 1.04-4.10, P = .039), whereas surgical intervention, age, GCS score, CCI, mFI-5, mFI-11, sex, and fracture displacement were not significantly correlated. CONCLUSIONS Mortality after type II odontoid fractures in elderly patients is common. mRS score at presentation may help predict mortality more accurately than other patient factors.

Abstract
PURPOSE Odontoid fractures are the most common cervical spine fractures in the elderly, with a controversial optimal treatment. The objective of this review was to compare the outcome of surgical and conservative treatments in elderly (≥ 65 years), by updating a systematic review published by the authors in 2013. METHODS A comprehensive search was conducted in seven databases. Clinical outcome was the primary outcome. Fracture union- and stability were secondary outcomes. Pooled point estimates and their respective 95% confidence intervals (CIs) were derived using the random-effects model. A random-effects multivariable meta-regression model was used to correct for baseline co-variates when sufficiently reported. RESULTS Forty-one studies met the inclusion criteria, of which forty were case series and one a cohort study. No clinical differences in outcomes including the Neck Disability Index (NDI, 700 patients), Visual Analogue Scale pain (VAS, 180 patients), and Smiley-Webster Scale (SWS, 231 patients) scores were identified between surgical and conservative treatments. However, fracture union was higher in surgically treated patients (pooled incidence 72.7%, 95% CI 66.1%, 78.5%, 31 studies, 988 patients) than in conservatively treated patients (40.2%, 95% CI 32.0%, 49.0%, 22 studies, 912 patients). This difference remained after correcting for age and fracture type. Fracture stability (41 studies, 1917 patients), although numerically favoring surgery, did not appear to differ between treatment groups. CONCLUSION While surgically treated patients showed higher union rates than conservatively treated patients, no clinically relevant differences were observed in NDI, VAS pain, and SWS scores and stability rates. These results need to be further confirmed in well-designed comparative studies with proper adjustment for confounding, such as age, fracture characteristics, and osteoporosis degree.

Abstract
Introduction The prevalence of trauma is increasing in the geriatric population. The optimal therapy for type II odontoid fractures in the elderly is controversial. This study aims to assess the morbidity and mortality associated with odontoid fractures in octogenarians undergoing C1/C2 posterior screw fixation and describe the perioperative and post-operative complications and risk factors associated with mortality. Materials and methods Electronic medical records from a single institution pertaining to the period between September 2005 and December 2020 were retrieved. Data on patient demographics, neurological conditions, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Results Over a 16-year period, 60 patients aged ≥80 years diagnosed with type II odontoid fractures were enrolled in the study. The mean age was 85.0 ± 1.9 years. The mean Charlson Comorbidity Index (CCI) was >6 indicating a poor baseline reserve (8.5 ± 1.9), while cardiovascular diseases were the most prevalent among comorbidities. The mean surgical duration was 217.5 ± 65.9 min, with a mean blood loss of 725.5 ± 275.7 mL. The in-hospital was 5-0% and the 90-day mortality rates increased at 10.0%. No revision surgery was needed in any of the cases. Intraoperative and post-operative X-ray and computed tomography (CT) imaging revealed correct screw placement. Proper alignment of the atlantoaxial spine and fusion could be achieved in all cases. The unique risk factors for mortality included the presence of comorbidities and the occurrence of post-operative complications. Conclusion The complication and mortality rates associated with odontoid fractures in octogenarians are relatively high. However, the therapeutic goals in this population also include bone union and preservation of neurological status. Despite the often-high comorbidity rate, we still recommend that surgery should be considered in patients over 80 years. However, it is necessary to evaluate several approaches when treating such frail patients.

Abstract
Odontoid fractures are increasingly prevalent in older adults and associated with high morbidity and mortality. Optimal management remains controversial. Our study aims to investigate the association between surgical management of odontoid fractures and in-hospital mortality in a multi-center geriatric cohort. We identified patients 65 years or older with C2 odontoid fractures from the Trauma Quality Improvement Program database. The primary study outcome was in-hospital mortality. Secondary outcomes were in-hospital complications and hospital length of stay. Generalized estimating equation models were used to compare outcomes between operative and non-operative cohorts. Among the 13,218 eligible patients, 1100 (8.3%) were treated surgically. The risk of in-hospital mortality did not differ between surgical and non-surgical groups, after patient and hospital-level adjustment (OR: 0.94, 95%CI: 0.55-1.60). The risks of major complications and immobility-related complications were higher in the operative cohort (adjusted OR: 2.12, 95%CI: 1.53-2.94; and OR: 2.24, 95%CI: 1.38-3.63, respectively). Patients undergoing surgery had extended in-hospital length of stay compared to the non-operative group (9 days, IQR: 6-12 days vs. 4 days, IQR: 3-7 days). These findings were supported by secondary analyses that considered between-center differences in rates of surgery. Among geriatric patients with odontoid fractures surgical management was associated with similar in-hospital mortality, but higher in-hospital complication rates compared to non-operative management. Surgical management of geriatric patients with odontoid fractures requires careful patient selection and consideration of pre-existing comorbidities.

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.

Reevaluation of a classification system: stable and unstable odontoid fractures in geriatric patients-a radiological outcome measurement. Eur J Trauma Emerg Surg 2022; 48:2967-2976. [PMID: 35597894 PMCID: PMC9360123 DOI: 10.1007/s00068-022-01985-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 04/16/2022] [Indexed: 11/30/2022]
Abstract
Objectives We carried out a retrospective cohort study to differentiate geriatric odontoid fractures into stable and unstable and correlated it with fracture fusion rates. Results are based on the literature and on our own experience. The authors propose that the simple Anderson and D’Alonzo classification may not be sufficient for geriatric patients. Methods There were 89 patients ≥ 65 years who presented at our institution with type II and III odontoid fractures from 2003 until 2017 and were included in this study. Each patient was categorized with CT scans to evaluate the type of fracture, fracture gap (mm), fracture angulation (°), fracture displacement (mm) and direction (ventral, dorsal). Fractures were categorized as stable [SF] or unstable [UF] distinguished by the parameters of its angulation (< / > 11°) and displacement (< / > 5 mm) with a follow-up time of 6 months. SFs were treated with a semi-rigid immobilization for 6 weeks, UFs surgically—preferably with a C1–C2 posterior fusion. Results The classification into SFs and UFs was significant for its angulation (P = 0.0006) and displacement (P < 0.0001). SF group (n = 57): A primary stable union was observed in 35, a stable non-union in 10, and an unstable non-union in 8 patients of which 4 were treated with a C1/2 fixation. The overall consolidation rate was 79%. UF group (n = 32): A posterior C1–C2 fusion was carried out in 23 patients, a C0 onto C4 stabilization in 7 and an anterior odontoid screw fixation in 2. The union rate was 100%. Twenty-one type II SFs (91%) consolidated with a nonoperative management (P < 0.001). A primary non-union occurred more often in type II than in type III fractures (P = 0.0023). There was no significant difference in the 30-day overall case fatality (P = 0.3786). Conclusion To separate dens fractures into SFs and UFs is feasible. For SFs, semi-rigid immobilization provides a high consolidation rate. Stable non-unions are acceptable, and the authors suggest a posterior transarticular C1–C2 fixation as the preferred surgical treatment for UFs. Level of evidence Level III.

Abstract
Type-II odontoid fractures are common and highly morbid injuries, particularly among elderly patients. However, few risk stratification resources exist to predict outcomes and guide management decision making. Frailty indices have been increasingly utilized for these purposes in elective surgery, but have not been assessed for trauma. A single-center prospective trauma registry identified patients aged ≥ 80 years with type-II odontoid fractures. Frailty was the independent variable, using three independent indices: modified-5-item frailty (mFI-5), modified Charlson comorbidity (mCCI), and Davies. 97 patients had complete frailty data and sufficient follow up information, with median mIF-5 of 2 (range 0-4; 34 frail, mFI-5 > 2), median mCCI score of 6 (range 4-14), and median Davies score of 2 (range 0-7). For all indices, increasing score was associated with mortality, mIF-5 (HR = 1.76, 95%CI = 1.06-2.88), mCCI (HR = 1.10, 95%CI = 1.01-1.20), and Davies scores (HR = 1.21, 95%CI = 1.08-1.37). Median post-injury survival among patients with mIF-5 of ≤ 2 was 10-fold longer than patients with mIF-5 of > 2 (70 vs. 710 days, p = 0.0026). After adjusting for initial treatment strategy, frailty status remained an independent predictor of patient mortality; mIF-5 (HR = 1.72, 95%CI = 1.02-2.80), mCCI (HR = 1.10, 95%CI = 1.01-1.20), and Davies scores (HR = 1.21, 95%CI = 1.08-1.37). Among octogenarian patients with type-II odontoid fractures, frailty was associated with increased mortality, independent of treatment strategy.

Abstract
Odontoid type II fractures represent the most common cervical spine injuries in the elderly. The decision for surgical treatment in very elderly patients is still controversial. The aim of this study was to assess morbidity and mortality in patients over 90 years of age undergoing CT-guided posterior stabilization for unstable odontoid type II fractures. A total of 15 patients with an acute traumatic odontoid type II fracture who received surgical treatment for unstable odontoid type II fractures were retrospectively analyzed. Complications, morbidity, and mortality as well as length of ICU and hospital stay were determined. Clinical follow-up evaluation was based on outpatient presentation and information from family members and general practitioners. Finally, we conducted a comparison of complications rates between patients over 90 years of age and patients between 65 and 89 years old with a type II odontoid fracture after CT-guided posterior stabilization in our institution. The mean age was 91.4 years. Patients were predominately female (87%). In-hospital deaths did not occur. The average length of the hospital stay was 13.4 days and 1.9 days for the ICU. Blood transfusion was necessary in two patients (13%). Two patients (13%) developed urinary tract infection, one patient (7%) a delirium, and another epistaxis (7%). One patient (7%) developed pneumonic sepsis and fully recovered within several weeks. The mean follow-up was 36 months (range 9–72 months). Implant-related complications developed in one patient (7%). Five patients died during the follow-up period, with an average time to death of 26.6 months. Postoperative bracing was not needed in any of the patients. Posterior stabilization of unstable odontoid fractures type II using CT-guided navigation in patients over 90 years of age is a safe and effective procedure with low complications and mortality rates.

Favorable prognosis with nonsurgical management of type III acute odontoid fractures: a consecutive series of 212 patients. Spine J 2021; 21:1149-1158. [PMID: 33577924 DOI: 10.1016/j.spinee.2021.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 02/01/2021] [Accepted: 02/06/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The recommended primary treatment for type III odontoid fractures (OFx) is external immobilization, except for patients having major displacement of the odontoid fragment. The bony fusion rate of type III OFx has been reported to be >85%. High compliance to treatment recommendations is favorable only if the treatment leads to a good outcome. PURPOSE The primary aim of this study was to determine the long-term outcome after conservative and surgical treatment of type III OFx and to reaffirm that primary external immobilization is the best treatment for most type III fractures. STUDY DESIGN/SETTING Retrospective study based on a prospective database. PATIENT SAMPLE Two hundred twelve consecutive patients with type III OFx treated at Oslo University Hospital over an 8-year period (2009-2017). OUTCOME MEASURES Long-term rates of bony fusion, crossover from primary conservative treatment to surgical fixation, new onset spinal cord injury (SCI), severe persistent neck pain (visual analogue scale - VAS), and persistent disability measured with Neck Disability index (NDI). METHODS The present study was based on data extracted from our quality control database for acute cervical spine fractures from a general population. During the years 2018 to 2019 long-term follow-up of alive patients was performed (median follow-up time was 38.0 months; range 3.0-108.0 months). The follow-up included neurological examination, radiological examination and scoring of bony fusion status, crossover from primary conservative treatment to surgical fixation, new onset SCI, neck pain, and Neck Disability Index (NDI score). RESULTS In this consecutive series of 212 patients with type III acute OFx, median patient age was 72 years, 56% had severe preinjury comorbidities (ASA score ≥3) and 22% lived dependently. Severe comorbidities and dependent living were significantly associated with increasing age (p<.001). The trauma mechanism was fall injury in 82%. The median age of patients injured by falls was significantly higher than in patients with a nonfall injury (p<.001). At the time of diagnosis, 4% had an OFx related SCI. Primary treatment was external immobilization alone in 95.3% and open surgical fixation in 4.7%. Patients treated with primary external immobilization alone presented with significantly less translation of the odontoid fragment (p<.001) and less angulation of the odontoid fragment (p=.025) than patients treated with primary surgery. Subsequent crossover to surgical fixation was performed in 5.4%. At long-term follow-up, 95.7% of patients had bony fusion of the OFx, 80.5% had minimal/no neck pain, and none developed new onset SCI. There was no significant difference in long-term follow-up VAS (p=.444) or NDI (p=.562) between the primary external immobilization group and the primary surgical group. CONCLUSION This study reaffirms that nonsurgical treatment remains the preferable option in the majority of patients with type III OFx.

Abstract
BACKGROUND Type II odontoid fractures are known to have low fusion rates following conservative management with a hard collar. However, most patients are elderly with comorbidities and are not fit for surgery. The present study identified the rates of bony fusion, complications, and clinical outcomes following conservative management of type II odontoid fractures. METHODS We included consecutive patients referred with a suspected odontoid fracture to a Major Trauma Centre in the UK between March 2015 and December 2017. Data including patient demographics, fracture management, complications and outcomes. Bony fusion was assessed by two neurosurgeons and one neuroradiologists. Results were analysed with simple statistics and chi-squared test. RESULTS 102 patients were included in the study (mean age = 80.4 ± 15.3). 10 (9.8%) were managed surgically and 92 (90.2%) were managed conservatively with a hard collar, for a mean of 87 days. Patients were followed up for a mean of 28.1 months (range 1-855 days) until discharge. 37% developed collar complications, namely pain, stiffness and non-tolerance. Bony union was achieved in 37.3% of patients treated with a hard collar (versus 80% in the surgical group, p = 0.0096). Increasing age was an independent risk factor for non-union (p < 0.001). Of the patients without bony union, none reported symptoms, and 90% were discharged without a collar. CONCLUSION The management of type II odontoid fractures are difficult in an elderly, co-morbid population. With conservative management fusion rates are low, and collar complications are not insignificant. However, outcomes are good regardless of union.

Abstract
Background Surgical fixation is recommended for type II and III odontoid fractures (OFx) with major translation of the odontoid fragment, regardless of the patient’s age, and for all type II OFx in patients aged ≥50 years. The level of compliance with this recommendation is unknown, and our hypothesis is that open surgical fixation is less frequently performed than recommended. We suspect that this discrepancy might be due to the older age and comorbidities among patients with OFx. Methods We present a prospective observational cohort study of all patients in the southeastern Norwegian population (3.0 million) diagnosed with a traumatic OFx in the period from 2015 to 2018. Results Three hundred thirty-six patients with an OFx were diagnosed, resulting in an overall incidence of 2.8/100000 persons/year. The median age of the patients was 80 years, and 45% were females. According to the Anderson and D’Alonzo classification, the OFx were type II in 199 patients (59%) and type III in 137 patients (41%). The primary fracture treatment was rigid collar alone in 79% of patients and open surgical fixation in 21%. In the multivariate analysis, the following parameters were significantly associated with surgery as the primary treatment: independent living, less serious comorbidities prior to the injury, type II OFx and major sagittal translation of the odontoid fragment. Conversion from external immobilization alone to subsequent open surgical fixation was performed in 10% of patients. Significant differences the in conversion rate were not observed between patients with type II and III fractures. The level of compliance with the treatment recommendations for OFx was low. The main deviation was the underuse of primary surgical fixation for type II OFx. The most common reasons listed for choosing primary external immobilization instead of primary surgical fixation were an older age and comorbidities. Conclusion Major comorbidities and an older age appear to be significant factors contributing to physicians’ decision to refrain from the surgical fixation of OFx. Hence, comorbidities and age should be considered for inclusion in the decision tree for the choice of treatment for OFx in future guidelines.

Abstract
OBJECTIVE The interlaminar fusion combination involving C1-C2 screwing fixation is one of the most effective techniques for atlantoaxial dislocation or subluxation, and the bone graft is usually stabilized by wiring constructs. However, some adverse events were reported during the insertion of sublaminar wiring, such as accidentally damaging the spinal cord or dura. Thus we used the miniplate to stabilize the harvest bone graft on the C1-C2 laminar, which led to a shorter operation time and prevented spinal canal violation. This study investigated the safety and efficacy of the novel surgical technique, namely miniplate-augmented interlaminar fusion. METHODS We retrospectively reviewed 43 patients who underwent posterior atlantoaxial fusion with the miniplate-augmented iliac crest autograft at our institute. Complications related to surgery were recorded and calculated. After operation, patients were followed up through routine radiography to examine whether the fusion of the atlantoaxial segment was achieved. Success of fusion was defined as follows: 1) the presence of bone bridging between the bone graft and both the atlas and axis; and 2) the absence of movement of the atlantoaxial spinous process on flexion-extension radiography, which meant that the variation of length measured in 2 views, respectively, was <1 mm. The first time when radiography showed successful fusion after surgery was termed as fusion time and was recorded individually. In addition, overall fusion rates and mean fusion times were analyzed. RESULTS Of 43 patients, long-term follow-up data were available for 31 patients, whereas the remaining 12 patients had dropped out (mean follow-up duration, 24.91 months; range, 6-72 months). Among 31 patients, 22 (70.96%) were women and 9 (29.03%) were men. The mean age was 63.33 years. Regarding the etiology, atlantoaxial dislocations or subluxations were caused due to degeneration, rheumatoid arthritis, odontoid fracture, trauma, and os odontoideum in 14 (45%), 3 (10%), 5 (16%), 8 (26%), and 1 (3%) patient(s), respectively. Successful fusion was achieved in 30 (96.77%) patients, with a mean fusion time of 6.23 months, whereas only 1 (3.23%) patient did not meet the fusion criteria. No complications related to the miniplate occurred. We noted vertebral artery rupture not requiring blood transfusion in 1 patient, aspiration pneumonia in 1 patient, urinary tract infection in 1 patient, anemia requiring transfusion in 1 patient, and leg dysesthesia in 1 patient. No neurologic deficit was found. CONCLUSIONS Miniplate-augmented interlaminar fusion with C1-C2 screwing resulted in excellent fusion rates with a considerably low probability of complications. Hence this novel technique for bone graft fixation with atlantoaxial screwing has a good efficacy and safety and can serve as an alternative for bone graft fixation during C1-C2 fusion.

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.

Abstract
OBJECTIVE For odontoid fractures, surgical treatment approaches including anterior odontoid screw fixation approach and the posterior C1-C2 arthrodesis approach are generally adopted in practice. However, the choice of different surgical procedures remains controversial. In addition to surgical technique, the fusion rate is an important factor contributing to the clinical efficacy. Therefore, this study was aimed to investigate the discrepancy in fusion rate between these two surgical approaches through synthesizing the currently available evidence on the topic. METHODS A computerized search of Ovid, Medline, Embase, and the Cochrane library up to December 2017 for literature on the complication rate during odontoid fracture treatment was conducted. Risk ratio (RR) with its 95% confidence interval (CI) was pooled to assess fusion rates after surgical treatments, including anterior odontoid screw fixation approach or posterior C1-2 arthrodesis procedure, for patients with odontoid fractures. RESULTS Thirteen studies were enrolled in the meta-analysis. Results show that no significant difference was found in the overall fusion rate (RR = 0.96, 95% CI 0.90-1.01). There was no significant heterogeneity among the studies (p value = 0.60). As to age- and economic-level subgroups, there was no statistical evidence to suggest an association of the patient age and economy development level with the choice of surgical approach. However, it is shown that better fusion rates of patients (≥ 60 years) in developed countries received a better fusion rates after posterior fixation compared with anterior group using the fixed-effect model (RR = 0.88, 95% CI 0.79-0.98). CONCLUSION Elderly patients (≥ 60 years) underwent posterior C1-2 arthrodesis fixation shows higher fusion rates in developed countries comparing with patients who underwent anterior odontoid screw fixation. Overall, there is no significant discrepancy between these two surgical approaches. However, the conclusion should be verified by further study enrolling larger sample size.

Abstract
OBJECTIVE Demographic changes have led to a higher incidence of C-2 fractures, especially in elderly patients. For patients with type II fractures, treatment remains controversial, as discussed by Anderson and D'Alonzo, due to the rising morbidity and mortality rates for any treatment. The aim of this study was to compare conservative and surgical management in patients with type II C-2 fractures regarding outcomes, complications, and the mortality rate. METHODS A retrospective analysis was performed of the medical records, X-rays, and/or computed tomography scans of patients ≥80 years of age with type II fractures who were admitted to our Department of Neurosurgery between January 1990 and December 2017. The success of treatment was evaluated 3 months after surgery. RESULTS In total, 125 patients were included, of whom 98 were treated surgically and 27 were treated conservatively. Surgical treatment was successful in 90.8% of cases, while conservative treatment was successful in 70.0%. The in-hospital mortality was 14.29% and the 3-month mortality was 27.8% in the surgical group, compared to 3.7% and 20% in the conservatively treated group. The in-hospital complication rate was 22.4% in the surgically treated patients and 7.4% in the conservatively treated patients. CONCLUSION Surgical treatment of type II fractures seemed to be associated with higher success and complication rates than conservative treatment. Nevertheless, 3-month mortality was comparable in both groups. Therefore, we conclude that surgical treatment for type II fractures in elderly patients is superior to conservative management, although conservative treatment remains a valuable option in elderly patients with severe comorbidities.

Abstract
BACKGROUND The aim of our study was to identify the demographics and complications in elderly cervical spine injuries and predictive factors for surgery, complications and mortality. We hypothesized younger healthier patients were more likely to undergo surgical intervention. METHODS A retrospective review of 225 consecutive patients aged 65 years and over with cervical spine injuries was carried out over a 3-year period. RESULTS There were 113 males and 112 females with an average of 79.7 years (range 65-98). The most common fracture was C2 peg type (21.8%). Five patients had complete spinal cord injury (2.2%), 25 had incomplete spinal cord injury (11.1%) and 84% were neurologically intact. Fifty-four patients were managed operatively (24%), while 171 patients were managed non-operatively (76%). The operative group had higher rates of pneumonia (odds ratio (OR) 5.3, 95% confidence interval (CI) 2.6-10.7, P < 0.01), cardiac arrhythmia (OR 4.1, 95% CI 1.5-11.2, P < 0.01) and respiratory failure (OR 2.6, 95% CI 1.2-5.5, P < 0.05). There was no difference in mortality between the operative and non-operative group (18.5% and 12.9%, P = 0.3). Patients with complete spinal cord injury had 100% mortality. Significant predictive factors for complications and death were neurological deficits, comorbidities and the presence of other injuries (P < 0.05). Surgery was not predictive for death and the operative group was younger than the non-operative group (P < 0.05). CONCLUSIONS In the setting of a high complication rate, consideration should be given to palliation in elderly patients with complete spinal cord injury and there must be good rational for surgery.

Abstract
Background Displaced odontoid fractures in the elderly are treated non-surgically with a cervical collar or surgically with C1–C2 fusion. Due to the paucity of evidence, the treatment decision is often left to the discretion of the expert surgeon. Methods The Uppsala Study on Odontoid Fracture Treatment (USOFT) is a multicentre, open-label, randomised controlled superiority trial evaluating the clinical superiority of the surgical treatment of type-2 odontoid fractures, with a 1-year Neck Disability Index (NDI) as the primary endpoint. Fifty consecutive patients aged ≥ 75 years, with displaced type-2 odontoid fracture, are randomised to non-surgical or surgical treatment. Excluded are patients with an American Society of Anaesthesiologists (ASA) score ≥ 4, dementia nursing care or anatomical cervical anomalies. The minimal clinically important difference of the NDI is 3.5 points. A minimum of 16 patients are needed in each group to test the superiority with 80% power. By considering a 1-year mortality forecast of 29%, up to 25 participants are recruited in each group. The non-surgical group is fitted with a rigid cervical collar for 12 weeks. The surgical group is treated with a posterior C1–C2 fusion. All participants are monitored with regard to the NDI, EuroQol score (EQ-5D), socio-demographics and computed tomography (CT) at the time of injury, at 6 weeks, 3 months and 12 months. At 12 months, a dynamic radiographical investigation of upper cervical stability is performed. The secondary endpoints are: EQ-5D score, activities of daily living (ADL), bony union, upper cervical stability and mortality. Discussion USOFT is the first randomised controlled trial comparing non-surgical and surgical management of type-2 odontoid fractures in the elderly. Using the NDI and EQ-5D as endpoints, future value-based decisions may consider quality-adjusted life years gained. Major limitations are (1) the allocation bias of the open-label study design, (2) that only higher training levels of all core specialties of spine surgery are included in the surgical treatment arm and (3) that only one type of surgical stabilisation is investigated (posterior C1–C2 fusion), while other methods are not included in this study. Trial registration ClinicalTrials.gov, NCT02789774. Registered retrospectively on 25 August 2015.

Abstract
OBJECTIVE The demographic change in the population leads to a rising number of patients presenting with fractures of the cervical spine, especially C-2, due to falls. With an increase of co-morbidities in these elder patients, the risk for intra- and postoperative complications is increased likewise. Thus, an alternative strategy instead of operative management of these fractures should be taken into account whenever possible. Conservative management of dens fractures in the elderly is still a subject of great controversy despite numerous studies on this topic. The aim of this study was to analyze the rate of successful osseous consolidation of C-2 fractures with conservative treatment by wearing a semi-rigid collar or halo thoracic vest without further surgical intervention. PATIENTS AND METHODS We analyzed the medical records and CT-scan of the cervical spine of 254 patients with C-2 fractures retrospectively, who were admitted to our department between January 1990 and September 2015. Fractures were diagnosed by CT-scan of the cervical spine and classified according to the Anderson - D`Alonzo classification. 183 patients were submitted to surgery as treatment of choice. In 71 patients a conservative management with external immobilization was chosen. The latter group was subjected to study analysis. RESULTS 71 patients (mean age 74.08 years ± 16.06 years) were diagnosed with C-2 fractures (Typ I: 4; Typ II 36; Typ III: 31) and treated conservatively using a Philadelphia collar (n = 57), or a halo-thoracic vest (n = 14), respectively. 12 patients were lost to follow up and excluded from further analysis. Conservative treatment of the fractures was deemed successful when a bony consolidation of the fracture in follow-up CT scans was seen (45 of 59 patients; 76.3%). 20 patients with a Type II fracture (20/28, 71.4%) showed a successful ossification. In 14 patients (overall 23.7%; Typ I: 1 (7.14%), Typ II: 8 (57.14%), Typ III: 5 (35.71%)) external immobilization failed to achieve primary stability. These patients were submitted to consecutive surgery. CONCLUSION From our data it can be concluded that elderly patients, presenting with non-dislocated Type II fractures of the axis without accompaining neurological deficits, will have a more than 70% chance for a bony consolidation by conservative management. Consolidation rates may be estimated even higher in Type I and III fractures. Therefore, we suggest that external immobilization might be a valuable option to treat elderly patients with these fractures under certain circumstances.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE Anterior fixation of odontoid fracture has been associated with high morbidity and mortality in small, single institution series. Identifying risk factors may improve risk stratification and highlight factors that could be optimized preoperatively. The objective of this study was to determine the 30-day complication rate following anterior fixation of odontoid fractures and to identify associated risk factors among patients in a large national database. METHODS Patients who underwent anterior fixation were identified in the American College of Surgeons National Quality Improvement Program database (ACS NSQIP) from 2007 to 2012. Patient demographics, medical comorbidities, perioperative complications, and postoperative complications up to 30 days were analyzed by univariate and multivariate analysis. RESULTS Overall, 103 patients met criteria for the study. The average age was 73.9 years and patients were predominantly white (85.4%). Cardiac comorbidity was common (66.0%), as were dependent functional status (14.6%) and bleeding disorders (13.6%). Complications occurred in 37.9% of patients, and mortality was high (6.8%). Age, white race, and history of bleeding disorders were independently predictive of complications in the multivariate analysis. The postoperative hospital stay was >5 days for 45.6% of patients. CONCLUSION In a large, multicenter database study, anterior fixation of odontoid fracture was associated with high morbidity and mortality. Although advanced age was associated with increased risk of complications, patients undergoing anterior fixation were older, on average, than in prior studies. Bleeding disorder was a potentially modifiable risk factor for complications that could be optimized prior to surgery.

Abstract
Purpose: Odontoid fracture is a very common cervical injury, especially in elderly patients. Despite the high frequency, the appropriate management is still debated. The aim of this study is to evaluate clinical and radiological outcomes after anterior screw fixation or halo vest (HV) in type II odontoid fracture in elderly patients. Materials and Methods: Between January 2013 and December 2015, 135 consecutive patients affected by odontoid process were found. According to inclusion and exclusion criteria, 57 patients were included in the study. Patients were evaluated with visual analog scale (VAS), Smiley–Webster Scale (SWS), Italian Version of the Neck Disability Index (NDI), and patient satisfaction during follow-up. Furthermore, radiological data were evaluated for bone healing. Student's t-test or Fisher's exact test was used between groups, analyzing radiological and clinical results, and level of statistical significance was set at P < 0.05. Results: Seventeen patients were female and 40 were male. Twenty-seven patients were included in surgical group (SG) while 30 were included in HV group with a mean follow-up of 37.74 ± 10.52 months. A significant difference (P < 0.05) between groups was found for pseudoarthrosis, with a lower rate for SG. No significant differences in term of VAS, NDI, and SWS were found between groups (P > 0.05); SG reached higher satisfaction than HV group (P = 0.0271). Conclusions: Both treatments are equivalent in terms of clinical outcomes, and they are a valuable choice in the management of type II odontoid fracture. However, it must be considered that patients could slightly tolerate HV and may need a change of treatment.

Abstract
STUDY DESIGN Evidence-based systematic review. OBJECTIVES To define the optimal treatment of fractures involving the C2 body, including those with concomitant injuries, based upon a systematic review of the literature. SUMMARY OF BACKGROUND DATA Axis body fractures have customarily been treated nonoperatively, but there are some injuries that may require operative intervention. High-quality literature is sparse and there are few class I or class II studies to guide treatment decisions. MATERIALS AND METHODS A literature search was conducted using PubMed (MEDLINE), Cochrane Central Register of Controlled Trials, and Scopus (EMBASE, MEDLINE, COMPENDEX). The quality of literature was rated according to a grading tool developed by the Center for Evidence-based Medicine. Operative and nonoperative treatment of axis body fractures were compared using fracture bony union as the primary outcome measure. As risk factors for nonunion were not consistently reported, cases were analyzed individually. RESULTS The literature search identified 62 studies, of which 10 were case reports which were excluded from the analysis. A total of 920 patients from 52 studies were included. The overall bony union rate for all axis body fractures was 91%. Although the majority of fractures were treated nonoperatively, there has been an increasing trend toward operative intervention for Benzel type III (transverse) axis body fractures. Nearly 76% of axis body fractures were classified as type III fractures, of which 88% united successfully. Nearly all Benzel type I and type II axis body fractures were successfully treated nonoperatively. The risk factors for nonunion included: a higher degree of subluxation, fracture displacement, comminution, concurrent injuries, delay in treatment, and older age. CONCLUSIONS High rates for fracture union are reported in the literature for axis body fractures with nonoperative treatment. High-quality prospective studies are required to develop consensus as to which C2 body fractures require operative fixation.

Abstract
Abstract
Odontoid fractures are the most common fracture of the axis and the most common cervical spine fracture in patients over 65. Despite their frequency, there is considerable ambiguity regarding optimal management strategies for these fractures in the elderly. Poor bone health and medical comorbidities contribute to increased surgical risk in this population; however, nonoperative management is associated with a risk of nonunion or fibrous union. We provide a review of the existing literature and discuss the classification and evaluation of odontoid fractures. The merits of operative vs nonoperative management, fibrous union, and the choice of operative approach in elderly patients are discussed. A treatment algorithm is presented based on the available literature. We believe that type I and type III odontoid fractures can be managed in a collar in most cases. Type II fractures with any additonal risk factors for nonunion (displacement, comminution, etc) should be considered for surgical management. However, the risks of surgery in an elderly population must be carefully considered on a case-by-case basis. In a frail elderly patient, a fibrous nonunion with close follow-up is an acceptable outcome. If operative management is chosen, a posterior approach is should be chosen when fracture- or patient-related factors make an anterior approach challenging. The high levels of morbidity and mortality associated with odontoid fractures should encourage all providers to pursue medical co-management and optimization of bone health following diagnosis.

Abstract
BACKGROUND The posterior screw fixation in atlas via posterior arch and lateral mass, also called C1 "pedicle" screw, combined with C2 pedicle screw fixiation has shown better biomechanical stability in unstable atlantoaxial fractures. However, its popularization has to fulfill the limitation imposed by anatomical characteristics. The aim of this study was to explore the manipulation, effect, and safety of the atlantoaxial transpedicular screw fixation under "direct vision" for the treatment of unstable atlantoaxial fracture. METHODS All the patients diagnosed with unstable atlantoaxial fracture, who received surgery treatment of C1,C2 internal fixation from January 2012 to December 2014 were reviewed. Only these patients that were diagnosed with atlantoaxial unstability secondary to trauma and were treated with atlantoaxial transpedicular screw fixation under "direct vision" and iliac autograft were included. The safety of transpedicular screw placement, postoperative outcome, atlantoaxial stability, autograft fusion, and complications was observed and analyzed retrospectively. The pain visual analog scale (VAS) and the Japanese Orthopedic Association (JOA) score were used as surgical curative effect evaluation standards. RESULTS We reviewed a total of 92 patients diagnosed with unstable atlantoaxial fracture, who received surgery treatment of C1,C2 internal fixation from January 2012 to December 2014, and 87 patients were treated with atlantoaxial transpedicular screw fixation under "direct vision" and were included this analysis. A total of 306 transpedicular screws in atlas and axis were placed successfully. All cases were followed-up >12 months. The overall breach rate was 11.36%. None of the breaches resulted in new-onset neurological sequela. The neurological status in cases with bilateral upper extremities numbness and lower extremities weakness had improved after surgery. At the latest follow-up, the neck VAS and JOA scores were significantly improved (P < .01) than those preoperatively. No cases demonstrated implantation failure and bone graft absorption on the postoperative x-ray films and CT scans. CONCLUSION Atlantoaxial transpedicular screw fixation under "direct vision" and iliac autograft for the treatment of unstable atlantoaxial fracture has shown simple manipulation and efficient performance. Thus, the technique of C1-C2 fixation is feasible in treating unstable atlantoaxial fracture.

Abstract
Aims We performed a retrospective, comparative study of elderly patients with an increased risk from anaesthesia who had undergone either anterior screw fixation (ASF) or halo vest immobilisation (HVI) for a type II odontoid fracture. Patients and Methods A total of 80 patients aged 65 years or more who had undergone either ASF or HVI for a type II odontoid fracture between 1988 and 2013 were reviewed. There were 47 women and 33 men with a mean age of 73 (65 to 96; standard deviation 7). All had an American Society of Anesthesiologists score of 2 or more. Results Patients who underwent ASF had a significantly better outcome than those who were treated by HVI. There was a rate of nonunion of 10% after ASF and 23% after HVI. Failure of reduction or fixation occurred in 11 patients (15%) but there was no significant difference between the two groups. Mortality rates were also similar: 9% (n = 3) after ASF and 8% (n = 4) after HVI. Conclusion We conclude that ASF is the preferred method of treatment in this group of elderly patients, having a significantly higher rate of fusion, better clinical outcome and a similar rate of general and treatment-related complications.

Abstract
Study design: Retrospective review Objectives: To present and discuss the outcome of halo jacket immobilisation of cervical spine injuries. Setting: National Spinal Injuries Unit in a Scottish University teaching Hospital. Methods: Retrospective review of case-notes and radiographs of all patients treated with halo jacket both as primary means of immobilisation or as adjunct to surgical stabilisation between 1992–1999 and followed up at a weekly halo clinic. Results: Out of a total one hundred and four patients with cervical spine injury, eighty-six were treated with Halo jacket as primary means of cervical immobilisation. Halo was used as adjunct to surgical stabilisation for the rest. There were nine cases of true failure. This is a failure rate of 10% for primary halo immobilisation. Of the nine patients who had failure of bony healing, four had fibrous healing, three had surgery to stabilise spine, two were subsequently lost to follow-up. The highest incidence of recurrence of subluxation occurred in patients with fracture/subluxation with a healing rate of 85%. Patients with ankylosing spondylitis did well. Odontoid fractures had 18% failure rate. The commonest complication was loss of reduction, followed by pin-site infection. Conclusion: Halo is an effective non-surgical treatment for the injured cervical spine at both upper and lower levels.

Abstract
BACKGROUND Odontoid fractures are common C-spine fractures in the elderly. However, the optimal treatment of odontoid fractures in the elderly is, still subject to controversy. HYPOTHESIS Surgical treatment has several advantages on conservative treatment, such as reduced mortality and lower incidence of non-union. This meta-analysis was performed to identify the efficacy of conservative treatment compared with surgical treatment and provides recommendations for using these procedures to treat type II odontoid fractures in the elderly. MATERIALS AND METHODS A systematic search of all studies published was conducted using the PubMed, EMBASE, OVID, ScienceDirect and Cochrane CENTRAL databases. The randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) that compared conservative treatment with surgical treatment and provided data on clinical effects were identified. The included trials were screened out strictly based on the criterion of inclusion and exclusion. The quality of included trials was evaluated. RevMan 5.1 was used for data analysis. RESULTS Twelve studies involving 730 patients met the inclusion criteria. There were 441 patients with conservative treatment and 289 with surgical treatment. The results of meta-analysis indicated that no difference with regard to the mortality was noted (P > 0.05) between the two procedures. However, there was statistically significant difference with respect to the non-union numbers (P < 0.05) between the two procedures. DISCUSSION Conservative treatment and surgical treatment are both effective procedures for treating type II odontoid fractures in the elderly. Compared with surgical treatment, there is no significant difference in mortality; With respect to non-union numbers, conservative treatment numbers are higher than surgical treatment. Due to the poor quality of the evidence currently available, high quality RCTs are required. Level of evidence Level II: low-powered prospective randomized trial meta-analysis.

Abstract
Odontoid fractures type II according to Anderson and d'Alonzo are not uncommon in the elderly patients. Still, due to the paucity of evidence the published treatment guidelines are far from equivocal. This systematic review focuses on the published results of type II odontoid fracture treatment in the elderly with regard to survival, nonunion, and complications. After a systematic literature research 38 publications were included. A cumulative analysis of 1284 published cases found greater survival if elderly patients with odontoid fractures type II received surgical treatment (RR = 0.64). With regard to nonunion in 669 published cases primary posterior fusion had the best fusion results. The systematic literature review came to the following conclusions. (1) Surgical stabilisation of odontoid fractures type II improves survival in patients between 65 and 85 years of age compared to nonsurgical treatment. (2) Posterior atlantoaxial fusion for odontoid fractures type II in the elderly has the greatest bony union rate. (3) Odontoid nonunion is not associated with worse clinical or functional results in the elderly. (4) The complication rate of nonsurgical treatment is similar to the complication rate of surgical treatment of odontoid fractures type II in the elderly.

Abstract
Cervical spine injuries represent a minority of injury cases in motor vehicles accidents but are a real threat to a patient's life. In the wide range of cervical spine injuries, odontoid (dens) fractures represent the most common findings. These fractures are more usually found in the elderly population due to the changes associated with age. Neurological deficit is not frequently found in these injuries. The following is a case presentation of a chronic odontoid fracture with neurological deficit in a young man that was discovered 23 years after he sustained a motor vehicle accident.

Abstract
Surgical treatment of unstable odontoid fracture (type II OBAR or HTAL) has progressed, with a range of techniques, the specificities of which need to be known so as to determine their respective roles in the therapeutic arsenal now available. A retrospective study of 22 patients operated on in our center for odontoid fracture between 2005 and 2010 examined the operative techniques employed and analyzed results in the light of the literature, so as to construct an updated decision tree. Two populations could be distinguished: elderly victims of simple fall (mean age, 82.1 years), and younger victims of high-energy trauma (mean age, 42.6 years). Surgical techniques comprised: anterior odontoid screwing (n=14), transarticular C1-C2 screwing on the posterior Magerl (n=3) or anterior Vaccaro approach (n=1), Harms' posterior C1-C2 arthrodesis (n=3), and occipitocervical arthrodesis (n=3). The overall complications rate for the series was 28%, including one case of non-union, at a mean 11 months' follow-up. The risk/benefit ratio may be hard to assess in elderly patients. However, anterior screwing restores odontoid anatomy and is the technique of choice in first intention for reducible fracture. In second intention, transarticular C1-C2arthrodesis may be performed on an anterior or posterior approach, depending on local vertebral artery anatomy. Harms' posterior C1-C2 arthrodesis allows fixation of non-reduced fractures. Occipitocervical arthrodesis is a last resort, as the associated morbidity rate is higher.

Abstract
PURPOSE Odontoid fractures are the most common cervical spine fractures in the elderly. As the population ages, their incidence is expected to increase progressively. The optimal treatment of this condition is still the subject of controversy. The objective of this review is to summarize and compare the outcome of surgical and conservative interventions in the elderly (≥ 65 years). METHODS A comprehensive search was conducted in nine databases of medical literature, supplemented by reference and citation tracking. Clinical status was considered the primary outcome. Fracture union and stability rates were considered secondary outcomes. RESULTS A total of nineteen studies met the inclusion criteria. All studies were performed retrospectively and were of limited quality. There was insufficient data, especially from direct comparisons, to determine the difference in clinical outcome between surgical and conservative interventions. Osseous union was achieved in 66-85 % of surgically treated patients and in 28-44 % of conservatively treated patients. Fracture stability was achieved in 82-97 % of surgically patients and in 53-79 % of conservatively treated patients. CONCLUSIONS There was insufficient data to determine a potential difference in clinical outcome between different treatment groups. Surgically treated patients showed higher osseous union rates compared to conservatively treated patients, possibly because of different selection mechanisms. The majority of patients appears to achieve fracture stability regardless of the applied treatment. A prospective trial with appropriate sample size is needed to identify the optimal treatment of odontoid fractures in the elderly and predictors for the success of either one of the available treatments.

Abstract
BACKGROUND The appropriate treatment of dens fractures is unclear. We established a staged treatment protocol for dens fractures and conducted a prospective study to evaluate the outcome of treatment based on this protocol. METHODS We prospectively evaluated sixty-nine consecutive patients who presented to our institution with a dens fracture. The mean duration of follow-up was 9.7 months (range, six to fifty-eight months). Fractures were categorized as stable or unstable. Stable fractures were treated by immobilization in a rigid collar. Patients seventy-five years or older with unstable fractures, patients with a neurological deficit, and patients with Anderson and D'Alonzo type-III fractures underwent posterior transarticular C1-C2 stabilization. Unstable fractures in patients younger than seventy-five years were stabilized with direct anterior screw fixation. Thirty-one patients were treated with a Philadelphia collar, twenty-five with posterior transarticular fixation, and thirteen with direct anterior screw fixation. RESULTS Fracture-healing or solid fusion of C1-C2 was documented in sixty-eight of sixty-nine treated patients at final follow-up. The remaining patient had a stable nonunion of the dens. Secondary procedures were performed in five patients. CONCLUSIONS Our treatment algorithm based on dens fracture type, fracture stability, and patient age was associated with a high success rate. Evaluating fracture stability is crucial when considering nonoperative treatment. External stabilization with a rigid cervical collar was adequate for stable fractures of the dens and was associated with a high healing rate. Posterior transarticular screw fixation of C1-C2 was associated with a high success rate, including in elderly patients. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
PURPOSE Type IIB odontoid fractures (OF) in elderly patients are life-threatening conditions. Optimal treatment of these fractures is still controversial. The aim of this study was to assess the clinical and radiological outcome of surgically treated type IIB OF by anterior screw fixation in octogenarians. METHODS Eleven octogenarians with type IIB OF were operated using anterior screw fixation. Follow-up assessment included operative mortality and morbidity rates, long-term functional outcome and fracture union and stability. RESULTS There was neither operative mortality nor morbidity. Five patients had excellent clinical outcome, two good outcome, one fair and three poor. Two patients died of unrelated causes 2 months after surgery. Radiographs showed stable bone union in four patients and stable fibrous union in five patients. CONCLUSIONS Given the results in this short series, we suggest that anterior screw fixation of Type IIB OF may be offered as primary treatment in octogenarians.

Abstract
Abstract
Background:
Type II odontoid fractures with additional chip fragments are rare in clinical practice, accounting for < 10% of all odontoid fractures. Hadley et al were the first to describe these fractures as an individual subtype (IIA).
Objective:
To analyze the outcome of patients after surgical or nonoperative treatment of Hadley type IIA odontoid fractures.
Methods:
We analyzed the records of 46 patients at an average of 64 years of age at the time of injury. Twenty-five patients underwent surgical stabilization by anterior screw fixation and were entered into study group A; 21 patients were treated non-operatively by halo vest immobilization and included in study group B.
Results:
Thirty-seven patients (84%) returned to their preinjury activity level and were satisfied with their treatment. Using the Cervical Spine Outcomes Questionnaire to quantify the clinical outcome, we had an overall outcome score of 21.8. We did not find a significant difference in the overall clinical outcome between study groups. Bony fusion was achieved in 35 patients (80%). We had a nonunion rate of 13% after anterior screw fixation and a significantly higher rate of 30% after halo vest immobilization. Failure of reduction or fixation occurred in 12 patients (27%), with a significantly higher failure rate after halo vest immobilization.
Conclusion:
Hadley type IIA odontoid fractures are inherently unstable and impede proper realignment. These fractures have a significantly increased risk for secondary loss of reduction and bony nonunion, particularly after nonoperative management. Early surgery should be considered to avoid further complications.

[PMID: 21892399 DOI: 10.3340/jkns.2011.50.1.17] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2011] [Revised: 04/30/2011] [Accepted: 07/01/2011] [Indexed: 12/26/2022] Open
Abstract
OBJECTIVE In the present study, authors retrospectively reviewed the clinical outcomes of halo-vest immobilization (HVI) versus surgical fixation in patients with odontoid fracture after either non-surgical treatment (HVI) or with surgical fixation. METHODS From April 1997 to December 2008, we treated a total of 60 patients with upper cervical spine injuries. This study included 31 (51.7%) patients (22 men, 9 women; mean age, 39.3 years) with types II and III odontoid process fractures. The average follow-up was 25.1 months. We reviewed digital radiographs and analyzed images according to type of injury and treatment outcomes, following conservative treatment with HVI and surgical management with screw fixation. RESULTS There were a total of 31 cases of types II and III odontoid process fractures (21 odontoid type II fractures, 10 type III fractures). Fifteen patients underwent HVI (10 type II fractures, 5 type III fractures). Nine (60%) out of 15 patients who underwent HVI experienced successful healing of odontoid fractures. The mean period for bone healing was 20.2 weeks. Sixteen patients underwent surgery including anterior screw fixation (6 cases), posterior C1-2 screw fixation (8), and transarticular screw fixation (2) for healing the odontoid fractures (11 type II fractures, 5 type III fractures). Fifteen (93.8%) out of 16 patients who underwent surgery achieved healing of cervical fractures. The average bone healing time was 17.6 weeks. CONCLUSION The overall healing rate was 60% after HVI and 93.8% with surgical management. Patients treated with surgery showed a higher fusion rate and shorter bony healing time than patients who received HVI. However, prospective studies are needed in the future to define better optimal treatment and cost-effective perspective for the treatment of odontoid fractures.

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 2010; 20:195-204.

Abstract
Considerable controversy exists regarding the optimal management of elderly patients with type II odontoid fractures. There is uncertainty regarding the consequences of non-union. The best treatment remains unclear because of the morbidity associated with prolonged cervical immobilisation versus the risks of surgical intervention. The objective of the study was to evaluate the published literature and determine the current evidence for the management of type II odontoid fractures in elderly. A search of the English language literature from January 1970 to date was performed using Medline and the following keywords: odontoid, fractures, cervical spine and elderly. The search was supplemented by cross-referencing between articles. Case reports and review articles were excluded although some were referred to in the discussion. Studies in patients aged 65 years with a minimum follow-up of 12 months were selected. One-hundred twenty-six articles were reviewed. No class I study was identified. There were two class II studies and the remaining were class III. Significant variability was found in the literature regarding mortality and morbidity rates in patients treated with and without halo vest immobilisation. In recent years several authors have claimed satisfactory results with anterior odontoid screw fixation while others have argued that this may lead to increased complications in this age group. Lately, the posterior cervical (Goel-Harms) construct has also gained popularity amongst surgeons. There is insufficient evidence to establish a standard or guideline for odontoid fracture management in elderly. While most authors agree that cervical immobilisation yields satisfactory results for type I and III fractures in the elderly, the optimal management for type II fractures remain unsolved. A prospective randomised controlled trial is recommended.

Abstract
Recognition of the incidence of odontoid fractures as well as the associated morbidity and unexpectedly high mortality rates has prompted significant changes in the management of these fractures in the past decade. Nonsurgical management of type II odontoid fracture has historically been associated with a high nonunion rate. Thus, new classification systems have been devised to identify patients who might benefit from early surgical treatment. The decision-making process is particularly difficult when treating elderly patients. Increased familiarity with anterior and posterior surgical techniques has led to more aggressive treatment of odontoid fracture, with the intent of hastening functional rehabilitation. However, these clinical decisions have been associated with a significant rate of complications. The treatment algorithm for odontoid fractures continues to evolve based on the improved understanding of, and evidence-based literature on, anterior screw fixation, posterior spinal fusion, and halo-vest immobilization.

Abstract
BACKGROUND Traumatic fractures of the second cervical vertebra are common, representing nearly 20% of all acute cervical spinal fracture-dislocation injuries. They are divided into 3 distinct injury patterns: odontoid fractures, hangman's fracture injuries, and fractures of the axis body, involving all other fracture injuries to the C2 vertebra. OBJECTIVE An evidence-based overview of the medical and surgical treatment strategies for each axis fracture injury sub-type. RESULTS Current medical and surgical management of traumatic fractures of the axis.
