[PMID: 37339698 DOI: 10.1016/j.spinee.2023.06.385] [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: 01/08/2023] [Revised: 05/10/2023] [Accepted: 06/14/2023] [Indexed: 06/22/2023]
Abstract
BACKGROUND CONTEXT Spinal cord injury (SCI) is a global health problem with a heavy economic burden. Surgery is considered as the cornerstone of SCI treatment. Although various organizations have formulated different guidelines on surgical treatment for SCI, the methodological quality of these guidelines has still not been critically appraised. PURPOSE We aim to systematically review and appraise the current guidelines on surgical treatments of SCI and summarize the related recommendations with the quality evaluation of supporting evidence. STUDY DESIGN Systematic review. METHODS Medline, Cochrane library, Web of Science, Embase, Google Scholar, and online guideline databases were searched from January 2000 to January 2022. The most updated and recent guidelines containing evidence-based or consensus-based recommendations and established by authoritative associations were included. The Appraisal of Guidelines for Research and Evaluation, 2nd edition instrument containing 6 domains (eg, applicability) was used to appraise the included guidelines. An evidence-grading scale (ie, level of evidence, LOE) was utilized to evaluate the quality of supporting evidence. The supporting evidence was categorized as A (the best quality), B, C, and D (the worst quality). RESULTS Ten guidelines from 2008 to 2020 were included, however, all of them acquired the lowest scores in the domain of applicability among all the six domains. Fourteen recommendations (eight evidence-based recommendations and six consensus-based recommendations) were totally involved. The SCI types of the population and timing of surgery were studied. Regarding the SCI types of the population, eight guidelines (8/10, 80%), two guidelines (2/10, 20%), and three guidelines (3/10, 30%) recommended surgical treatment for patients with SCI without further clarification of characteristics, incomplete SCI, and traumatic central cord syndrome (TCCS), respectively. Besides, one guideline (1/10, 10%) recommended against surgery for patients with SCI without radiographic abnormality. Regarding the timing of surgery, there were eight guidelines (8/10, 80%), two guidelines (2/10, 20%), and two guidelines (2/10, 20%) with recommendations for patients with SCI without further clarification of characteristics, incomplete SCI, and TCCS, respectively. For patients with SCI without further clarification of characteristics, all eight guidelines (8/8, 100%) recommended for early surgery and five guidelines (5/8, 62.5%) recommended for the specific timing, which ranged from within 8 hours to within 48 hours. For patients with incomplete SCI, two guidelines (2/2, 100%) recommended for early surgery, without specific time thresholds. For patients with TCCS, one guideline (1/2, 50%) recommended for surgery within 24 hours, and another guideline (1/2, 50%) simply recommended for early surgery. The LOE was B in eight recommendations, C in three recommendations, and D in three recommendations. CONCLUSIONS We remind the reader that even the highest quality guidelines often have significant flaws (eg, poor applicability), and some of the conclusions are based on consensus recommendations which is certainly less than ideal. With these caveats, we found most included guidelines (8/10, 80%) recommended early surgical treatment for patients after SCI, which was consistent between evidence-based recommendations and consensus-based recommendations. Regarding the specific timing of surgery, the recommended time threshold did vary, but it was usually within 8 to 48 hours, where the LOE was B to D.

Int J Surg 2023; 109:3827-3835. [PMID: 37678281 PMCID: PMC10720809 DOI: 10.1097/js9.0000000000000696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 08/06/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Traumatic spinal injury (TSI) is associated with significant fatality and social burden; however, the epidemiology and treatment of patients with TSI in the US remain unclear. MATERIALS AND METHODS An adult population was selected from the National Inpatient Sample database from 2016 to 2019. TSI incidence was calculated and TSI-related hospitalizations were divided into operative and nonoperative groups according to the treatments received. TSIs were classified as fracture, dislocation, internal organ injury, nerve root injury, or sprain injuries based on their nature. The annual percentage change (APC) was calculated to identify trends. In-hospital deaths were utilized to evaluate the prognosis of different TSIs. RESULTS Overall, 95 047 adult patients were hospitalized with TSI in the US from 2016 to 2019, with an incidence rate of 48.4 per 100 000 persons in 2019 (95% CI: 46.2-50.6). The total incidence increased with an APC of 1.5% (95% CI: 0.1-3%) from 2016 to 2019. Operative TSI treatment was more common than nonoperative (32.8 vs. 3.8; 95% CI: 32.3-33.2 vs. 3.6-4%). The number of operations increased from 37 555 (95% CI: 34 674-40 436) to 40 460 (95% CI: 37 372-43 548); however, the operative rate only increased for internal organ injury (i.e. spinal cord injury [SCI])-related hospitalizations (APC, 3.6%; 95% CI: 2.8-4.4%). In-hospital mortality was highest among SCI-related hospitalizations, recorded at 3.9% (95% CI: 2.9-5%) and 28% (95% CI: 17.9-38.2%) in the operative and nonoperative groups, respectively. CONCLUSIONS The estimated incidence of TSI in US adults increased from 2016 to 2019. The number of operations increased; however, the proportion of operations performed on TSI-related hospitalizations did not significantly change. In 2019, SCI was the highest associated mortality TSI, regardless of operative or nonoperative treatment.

Abstract
STUDY DESIGN A meta-analysis of early surgery for acute thoracolumbar spinal cord injury. OBJECTIVE To evaluate whether early surgery increases the American Spinal Injury Association (ASIA) grade of patients confronted with acute thoracolumbar spinal cord injury. SUMMARY OF BACKGROUND DATA The idea that early surgery aids the recovery of spinal cord function in patients confronted with acute thoracolumbar spinal cord injury is controversial. METHODS All articles were retrieved from the PubMed, Embase, Web of Science and Scopus databases, which were searched from onset until 1 May 2021. All data are presented as odds ratios (ORs) and mean deviations (MDs) with 95% confidential intervals (CIs). RESULTS Ten studies, including 6 prospective studies, 3 retrospective studies, and 1 randomized controlled trial, containing 952 patients, were included in the analysis. The results showed that early surgery significantly reduced the number of patients with ASIA grade A (OR 0.27, 95% CI: 0.13-0.58, P <0.01) and B (OR 0.56, 95% CI: 0.39-0.82, P <0.01) status but greatly increased the number of patients with grade E status (OR 1.44, 95% CI: 1.06-1.96, P <0.01). Generally, the patients receiving early surgery achieved >1 ASIA grade improvement (OR 1.70, 95% CI: 1.31-2.21, P <0.01) or >2 ASIA grade (OR 3.55, 95% CI: 2.20-5.70, P <0.01) improvements. Although early surgery did not reduce the incidence of operative complications (OR 0.72, 95% CI: 0.45-1.16, P <0.01), the duration of hospitalization was greatly shortened (MD-3.48, 95% CI: -0.45 to-2.91, P <0.01). CONCLUSIONS The spinal cord function of acute thoracolumbar spinal cord injury patients can benefit from early decompression. This conclusion should be further verified with randomized controlled trials.

Abstract
INTRODUCTION Traumatic spinal injuries are frequent and their management is debated, especially in major trauma patients. This study aims to describe a large population of major trauma patients with vertebral fractures to improve prevention measures and fracture management. PATIENTS AND METHODS Retrospective analysis of 6274 trauma patients prospectively collected between October 2010 and October 2020. Collected data include demographics, mechanism of trauma, type of imaging, fracture morphology, associated injuries, injury severity score (ISS), survival, and death timing. The statistical analysis focused on mechanism of trauma and the search of predictive factors for critical fractures. RESULTS Patients showed a mean age of 47 years and 72.5% were males. Trauma included 59.9% of road accidents and 35.1% of falls. 30.7% patients had at least a severe fracture, while 17.2% had fractures in multiple spinal regions. 13.7% fractures were complicated by spinal cord injury (SCI). The mean ISS of the total population was 26.4 (SD 16.3), with 70.7% patients having an ISS≥16. There is a higher rate of severe fractures in fall cases (40.1%) compared to RA (21.9% to 26.3%). The probability of a severe fracture increased by 164% in the case of fall and by 77% in presence of AIS≥3 associated injury of head/neck while reduced by 34% in presence of extremities associated injuries. Multiple level injuries increased with ISS rise and in the case of extremities associated injuries. The probability of a severe upper cervical fracture increased by 5.95 times in the presence of facial associated injuries. The mean length of stay was 24.7 days and 9.6% of patients died. CONCLUSIONS In Italy, road accidents are still the most frequent trauma mechanism and cause more cervico-thoracic fractures, while falls cause more lumbar fractures. Spinal cord injuries represent an indicator of more severe trauma. In motorcyclists or fallers/jumpers, there is a higher risk of severe fractures. When a spinal injury is diagnosed, the probability of a second vertebral fracture is consistent. These data could help the decisional workflow in the management of major trauma patients with vertebral injury.

Abstract
BACKGROUND Acute vertebral fracture is usually caused by low-energy injury with osteoporosis and high-energy trauma. The AOSpine thoracolumbar spine injury classification system (AO classification) plays an important role in the diagnosis and treatment of the disease. The diagnosis and description of vertebral fractures according to the classification scheme requires a great deal of time and energy for radiologists. PURPOSE To design and validate a multistage deep learning system (multistage AO system) for the automatic detection, localization and classification of acute thoracolumbar vertebral body fractures according to AO classification on computed tomography. MATERIALS AND METHODS The CT images of 1,217 patients who came to our hospital from January 2015 to December 2019 were collected retrospectively. The fractures were marked and classified by 2 junior radiology residents according to the type A standard in the AO classification. Marked fracture sites included the upper endplate, lower endplate and posterior wall. When there were inconsistent opinions on classification labels, the final result was determined by a director radiologist. We integrated different networks into different stages of the overall framework. U-net and a graph convolutional neural network (U-GCN) are used to realize the location and classification of the thoracolumbar spine. Next, a classification network is used to detect whether the thoracolumbar spine has a fracture. In the third stage, we detect fractures in different parts of the thoracolumbar spine by using a multibranch output network and finally obtain the AO types. RESULTS The mean age of the patients was 61.87 years with a standard deviation of 17.04 years, consisting of 760 female patients and 457 male patients. On vertebrae level, sensitivity for fracture detection was 95.23% in test dataset, with an accuracy of 97.93% and a specificity of 98.35%. For the classification of vertebral body fractures, the balanced accuracy was 79.56%, with an AUC of 0.904 for type A1, 0.945 for type A2, 0.878 for type A3 and 0.942 for type A4. CONCLUSION The multistage AO system can automatically detect and classify acute vertebral body fractures in the thoracolumbar spine on CT images according to AO classification with high accuracy.

Abstract
BACKGROUND Spine fractures are frequently associated with additional injuries in the trauma setting, with chest wall trauma being particularly common. Limited literature exists on the management of flail chest physiology with concurrent unstable spinal injury. The authors present a case in which flail chest physiology precluded safe prone surgery and after rib fixation the patient tolerated spinal fixation without further issue. OBSERVATIONS Flail chest physiology can cause cardiovascular decompensation in the prone position. Stabilization of the chest wall addresses this instability allowing for safe prone spinal surgery. LESSONS Chest wall fixation should be considered in select cases of flail chest physiology prior to stabilization of the spinal column in the prone position. Further research is necessary to identify patients that are at highest risk to not tolerate prone surgery.

Abstract
BACKGROUND Our aim was to describe the characteristics of vertebral fractures, the presence of associated injuries, and clinical status within the first days in a severe trauma population. METHODS All patients with severe trauma admitted to our level 1 trauma center between January 2015 and December 2018 with a vertebral fracture were analyzed retrospectively. The fractures were determined by the AO Spine classification as stable (A0, A1, and A2 types) or unstable (A3, A4, B, and C types). Clinical status was defined as stable, intermediate, or unstable based on clinicobiological parameters and anatomic injuries. Severe extraspinal injuries and emergent procedures were studied. Three groups were compared: stable fracture, unstable fracture, and spinal cord injury (SCI) group. RESULTS A total of 425 patients were included (mean ± SD age, 43.8 ± 19.6 years; median Injury Severity Score, 22 [interquartile range, 17-34]; 72% male); 72 (17%) in the SCI group, 116 (27%) in the unstable fracture group, and 237 (56%) in the stable fracture group; 62% (95% confidence interval [CI], 57-67%) had not a stable clinical status on admission (unstable, 30%; intermediate, 32%), regardless of the group (p = 0.38). This decreased to 31% (95% CI, 27-35%) on day 3 and 23% (95% CI, 19-27%) on day 5, regardless of the group (p = 0.27 and p = 0.25). Progression toward stable clinical status between D1 and D5 was 63% (95% CI, 58-68%) overall but was statistically lower in the SCI group. Severe extraspinal injuries (85% [95% CI, 82-89%]) and extraspinal emergent procedures (56% [95% CI, 52-61%]) were comparable between the three groups. Only abdominal injuries and hemostatic procedures significantly differed significantly (p = 0.003 and p = 0.009). CONCLUSION More than the half of the patients with severe trauma had altered initial clinical status or severe extraspinal injuries that were not compatible with safe early surgical management for the vertebral fracture. These observations were independent of the stability of the fracture or the presence of an SCI. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

Abstract
INTRODUCTION AND OBJETCTIVES Our objective was to compare the rate of complications in thoracolumbar fractures that occurred during the early postoperative period in patients with multiple high-energy trauma according to the time of surgery. As a secondary objective, to estimate which variables were associated with surgery before 72h. MATERIAL AND METHODS Retrospective analysis of a series of patients with thoracolumbar fractures and multiple associated injuries in other anatomical regions due to high energy trauma. Surgically treated in an occupational trauma referral center, by the same surgical team and during the period between January 2013 and December 2019. RESULTS We analyzed a sample of 40 patients (39 men and 1 woman). The rate of complications was independent of surgical delay (before and after 72h) (p=0.827). There were statistically significant differences between early and later surgery groups in the variables age, systolic blood pressure, initial SOFA score and presence of neurological damage (p=0.014; p=0.029; p=0.032; p=0.012). The overall surgical delay was correlated with the SOFA score (p=0.007). CONCLUSION The rate of early postoperative complications did not show significant differences between the early and late surgery groups. We observed that the patients who had been operated before 72h from trauma were younger, had more association with neurological syntoms, presented higher blood pressure values and less physiological damage. Surgical delay was positively correlated with SOFA score on arrival.

Abstract
There are limited data pertaining to current practices in timing of surgical decompression for acute thoracolumbar spinal cord injury (SCI). We conducted a retrospective cohort study to evaluate variability in timing between- and within-trauma centers in North America; and to identify patient- and hospital-level factors associated with treatment delay. Adults with acute thoracolumbar SCI who underwent decompressive surgery within five days of injury at participating trauma centers in the American College of Surgeons Trauma Quality Improvement Program were included. Mixed-effects regression with a random intercept for trauma center was used to model the outcome of time to surgical decompression and assess risk-adjusted variability in surgery timeliness across centers. 3,948 patients admitted to 214 TQIP centers were eligible. 28 centers were outliers, with a significantly shorter or longer time to surgery than average. Case-mix and hospital characteristics explained < 1% of between-hospital variability in surgical timing. Moreover, only 7% of surgical timing variability within-centers was explained by case-mix characteristics. The adjusted intraclass correlation coefficient of 12% suggested poor correlation of surgical timing for patients with similar characteristics treated at the same center. These findings support the need for further research into the optimal timing of surgical intervention for thoracolumbar SCI.

Abstract
Early surgical intervention to decompress the spinal cord and stabilize the spinal column in patients with acute traumatic thoracolumbar spinal cord injury (TLSCI) may lessen the risk of developing complications and improve outcomes. However, there has yet to be agreement on what constitutes "early" surgery; reported thresholds range from 8 to 72 h. To address this knowledge gap, we conducted an observational cohort study using data from the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) from 2010 to 2016. The association between time from hospital arrival to surgical intervention and risk of major complications was assessed using restricted cubic splines. Propensity score matching was then used to assess the association between delayed surgery and risk of complications. Across 354 trauma centers 4108 adult TLSCI patients who underwent surgery were included. Median time-to-surgery was 18.8 h (interquartile range [IQR]: 7.4-40.9 h). The spline model suggests the risk of major complication rises consistently after a 12-h surgical wait-time. After propensity score matching, the odds of major complication were significantly lower for those receiving surgery within 12 h (odds ratio [OR] 0.77, 95% confidence interval [CI]: 0.64 to 0.94). This was also true for immobility-related complications (OR 0.79, 95% CI: 0.64 to 0.97). Patients in the early group spent 1.5 fewer days in the critical care unit on average (95% CI: -2.09 to -0.88). Although surgery within 12 h may not always be feasible, these data suggest that whenever possible surgeons should strive to reduce the amount of time between hospital arrival and surgical intervention, and health care systems should support this endeavor.

A study of probable benefit of a bioresorbable polymer scaffold for safety and neurological recovery in patients with complete thoracic spinal cord injury: 6-month results from the INSPIRE study. J Neurosurg Spine 2021:1-10.

Abstract
OBJECTIVE The aim of this study was to evaluate whether the investigational Neuro-Spinal Scaffold (NSS), a highly porous bioresorbable polymer device, demonstrates probable benefit for safety and neurological recovery in patients with complete (AIS grade A) T2-12 spinal cord injury (SCI) when implanted ≤ 96 hours postinjury. METHODS This was a prospective, open-label, multicenter, single-arm study in patients with a visible contusion on MRI. The NSS was implanted into the epicenter of the postirrigation intramedullary spinal cord contusion cavity with the intention of providing structural support to the injured spinal cord parenchyma. The primary efficacy endpoint was the proportion of patients who had an improvement of ≥ 1 AIS grade (i.e., conversion from complete paraplegia to incomplete paraplegia) at the 6-month follow-up visit. A preset objective performance criterion established for the study was defined as an AIS grade conversion rate of ≥ 25%. Secondary endpoints included change in neurological level of injury (NLI). This analysis reports on data through 6-month follow-up assessments. RESULTS Nineteen patients underwent NSS implantation. There were 3 early withdrawals due to death, which were all determined by investigators to be unrelated to the NSS or the implantation procedure. Seven of 16 patients (43.8%) who completed the 6-month follow-up visit had conversion of neurological status (AIS grade A to grade B [n = 5] or C [n = 2]). Five patients showed improvement in NLI of 1 to 2 levels compared with preimplantation assessment, 3 patients showed no change, and 8 patients showed deterioration of 1 to 4 levels. There were no unanticipated or serious adverse device effects or serious adverse events related to the NSS or the implantation procedure as determined by investigators. CONCLUSIONS In this first-in-human study, implantation of the NSS within the spinal cord appeared to be safe in the setting of surgical decompression and stabilization for complete (AIS grade A) thoracic SCI. It was associated with a 6-month AIS grade conversion rate that exceeded historical controls. The INSPIRE study data demonstrate that the potential benefits of the NSS outweigh the risks in this patient population and support further clinical investigation in a randomized controlled trial.Clinical trial registration no.: NCT02138110 (clinicaltrials.gov).

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE Little is known about operative management of traumatic spinal injuries (TSI) in low- and middle-income countries (LMIC). In patients undergoing surgery for TSI in Tanzania, we sought to (1) determine factors involved in the operative decision-making process, specifically implant availability and surgical judgment; (2) report neurologic outcomes; and (3) evaluate time to surgery. METHODS All patients from October 2016 to June 2019 who presented with TSI and underwent surgical stabilization. Fracture type, operation, neurologic status, and time-to-care was collected. RESULTS Ninety-seven patients underwent operative stabilization, 23 (24%) cervical and 74 (77%) thoracic/lumbar. Cervical operations included 4 (17%) anterior cervical discectomy and fusion with plate, 7 (30%) anterior cervical corpectomy with tricortical iliac crest graft and plate, and 12 (52%) posterior cervical laminectomy and fusion with lateral mass screws. All 74 (100%) of thoracic/lumbar fractures were treated with posterolateral pedicle screws. Short-segment fixation was used in 86%, and constructs often ended at an injured (61%) or junctional (62%) level. Sixteen (17%) patients improved at least 1 ASIA grade. The sole predictor of neurologic improvement was faster time from admission to surgery (odds ratio = 1.04, P = .011, 95%CI = 1.01-1.07). Median (range) time in days included: injury to admission 2 (0-29), admission to operating room 23 (0-81), and operating room to discharge 8 (2-31). CONCLUSIONS In a cohort of LMIC patients with TSI undergoing stabilization, the principle driver of operative decision making was cost of implants. Faster time from admission to surgery was associated with neurologic improvement, yet significant delays to surgery were seen due to patients' inability to pay for implants. Several themes for improvement emerged: early surgery, implant availability, prehospital transfer, and long-term follow-up.

Abstract
STUDY DESIGN A narrative literature review. OBJECTIVES To review the neurological recovery patterns in traumatic spinal cord injury (tSCI) patients with a complete lack of motor and sensory function below the level of injury (ie, ASIA A [American Spinal Injury Association scale]), as well as the impact of level of injury and timing of surgical intervention. RESULTS Spontaneous neurological recovery in patients with complete tSCI differs per level of injury: patients with cervical and thoracolumbar tSCI recover ≥1 ASIA grade in 17.3% to 34.0% 1 year after injury, compared with 10.7% to 18.6% in thoracic tSCI. Surgical decompression within 24 hours has a beneficial effect on neurological recovery in patients with complete cervical tSCI, whereas this effect is less clear for thoracic and thoracolumbar tSCI. A 1- or 2-grade improvement in the ASIA scale does not necessarily result in functional recovery. CONCLUSION In complete tSCI, the level of injury as well as surgical timing affect neurological recovery. There appears to be a beneficial effect of early surgical decompression in patients with complete cervical tSCI, more so than for thoracic and thoracolumbar tSCI. Frequently, the effect of surgical intervention is evaluated by an improvement in ASIA grade, but it is unclear whether this scale is sensitive enough to evaluate meaningful effectiveness of the intervention and desired outcome for patients with tSCI.
