[Translated article] Efficacy of early versus delayed spinal cord decompression in neurological recovery after traumatic spinal cord injury: Systematic review and meta-analysis. Rev Esp Cir Ortop Traumatol (Engl Ed) 2024:S1888-4415(24)00116-4. [PMID: 38971564 DOI: 10.1016/j.recot.2024.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 09/19/2023] [Accepted: 09/21/2023] [Indexed: 07/08/2024] Open
Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To compare early (<24h) versus late (>24h) spinal cord decompression on neurological recovery in patients with acute spinal cord injury. METHODS A systematic review was performed according to the PRISMA protocol to identify studies published up to December 2022. Prospective cohort studies and controlled trials comparing early versus delayed decompression on neurological recovery were included. Variables included number of patients, level of injury, treatment time, ASIA grade, neurological recovery, use of corticosteroids, and complications. For the meta-analysis, the "forest plot" graph was developed. The risk of bias of the included studies was assessed using the ROBINS-I22 and Rob223 tools. RESULTS Six of the seven studies selected for our review were included in the meta-analysis, with a total of 1188 patients (592 patients in the early decompression group and 596 in the delayed decompression group), the mean follow-up was 8 months, in 5 studies used methylprednisolone, the most reported complications were thromboembolic cardiopulmonary events. Five studies showed significant differences in favour of early decompression (risk difference 0.10, 95% confidence interval 0.07-0.14, heterogeneity 46%). The benefit was greatest in cervical and incomplete injuries. CONCLUSION There is scientific evidence to recommend early decompression in the first 24h after traumatic spinal cord injury, as it improves final neurological recovery, and it should be recommended whenever the patient and hospital conditions allow it to be safely done.

Abstract
BACKGROUND AND OBJECTIVES Central cord syndrome (CCS) is expected to become the most common traumatic spinal cord injury, yet its optimal management remains unclear. This study aimed to evaluate variability in nonoperative vs operative treatment for CCS between trauma centers in the American College of Surgeons Trauma Quality Improvement Program, identify patient- and hospital-level factors associated with treatment, and determine the association of treatment with outcomes. METHODS Adults with CCS were identified from the Trauma Quality Improvement Program database (2014-2016). Mixed-effects modeling with a random intercept for trauma centers was used to examine the adjusted association of patient- and hospital-level variables with nonoperative treatment. The random-effects output of the model assessed the risk-adjusted variability in nonoperative treatment across centers. Outlier hospitals were identified, and the median odds ratio was calculated. The adjusted effect of nonoperative treatment on mortality, morbidity, and hospital length of stay (LOS) was examined at the patient and hospital level by mixed-effects regression. RESULTS Three thousand, nine hundred twenty-eight patients across 255 centers were eligible; of these, 1523 (38.8%) were treated nonoperatively. Older age, noncommercial insurance (odds ratio [OR] 1.26, 95% CI 1.08-1.48, P = .004), absence of fracture (OR 0.58, 95% CI 0.49-0.68, P < .001), severe head injury (OR 1.41, 95% CI 1.09-1.82, P = .008), and comatose presentation (1.82, 95% CI 1.15-2.89, P = .011) were associated with nonoperative treatment. Twenty-eight hospitals were outliers, and the median odds ratio was 2.02. Patients receiving nonoperative treatment had shorter LOS (mean difference -4.65 days). Nonoperative treatment was associated with lesser in-hospital morbidity (OR 0.49, 95% CI 0.37-0.63, P < .001) at the patient level. There was no difference in mortality. CONCLUSION Operative decision-making for CCS is influenced by patient factors. There remains substantial variability between trauma centers not explained by case-mix differences. Nonoperative treatment was associated with shorter hospital LOS and lesser inpatient morbidity.

Abstract
STUDY DESIGN A modified Delphi study. OBJECTIVE To assess current practice patterns in the management of cervical spinal cord injury (SCI) and develop a simplified, practical classification system which offers ease of use in the acute setting, incorporates modern diagnostic tools and provides utility in determining treatment strategies for cervical SCI. METHODS A three-phase modified Delphi procedure was performed between April 2020 and December 2021. During the first phase, members of the AOSpine SCI Knowledge forum proposed variables of importance for classifying and treating cervical SCI. The second phase involved an international survey of spine surgeons gauging practices surrounding the role and timing of surgery for cervical SCI and opinions regarding factors which most influence these practices. For the third phase, information obtained from phases 1 and 2 were used to draft a new classification system. RESULTS 396 surgeons responded to the survey. Neurological status, spinal stability and cord compression were the most important variables influencing decisions surrounding the role and timing of surgery. The majority (>50%) of respondents preferred to perform surgery within 24 hours post-SCI in clinical scenarios in which there was instability, severe cord compression or severe neurology. Situations in which <50% of respondents were inclined to operate early included: SCI with mild neurological impairments, with cord compression but without instability (with or without medical comorbidities), and SCI without cord compression or instability. CONCLUSIONS Spinal stability, cord compression and neurological status are the most important variables influencing surgeons' practices surrounding the surgical management of cervical SCI. Based on these results, a simplified classification system for acute cervical SCI has been proposed.

Abstract
STUDY DESIGN Cross-sectional, international survey. OBJECTIVES To examine current international practices as well as knowledge, adoption, and barriers to guideline implementation for acute spinal cord injury (SCI) management. METHODS A survey was distributed to members of AO Spine. The questionnaire was structured to obtain demographic data and preferred acute SCI practices surrounding steroid use, hemodynamic management, and timing of surgical decompression. RESULTS 593 members completed the survey including orthopaedic surgeons (54.3%), neurosurgeons (35.6%), and traumatologists (8.4%). Most (61.2%) respondents were from low and middle-income countries (LMICs). 53.6% of physicians used steroids for the treatment of acute SCIs. Respondents from LMICs were more likely to administer steroids than HICs (178 vs. 78; P < .001). 331 respondents (81.5%) answered that patients would receive mean arterial pressure (MAP) targeted treatment. In LMICs, SCI patients were less likely to be provided with MAP-targeted treatment (76.9%) as compared to HICs (89%; P < .05). The majority of respondents (87.8%) reported that patients would benefit from early decompression. Despite overwhelming evidence and surgeons' responses that would offer early surgery, 62.4% of respondents stated they encounter logistical barriers in their institutions. This was particularly evident in LMICs, where 57.9% of respondents indicated that early intervention was unlikely to be accomplished, while only 21.1% of respondents from HICs stated the same (P < .001). CONCLUSION This survey highlights challenges in the implementation of standardized global practices in the management of acute SCI. Future research efforts will need to refine SCI guidelines and address barriers to guideline implementation.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024; 33:1213-1222. [PMID: 38217717 DOI: 10.1007/s00586-023-08085-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 11/14/2023] [Accepted: 12/04/2023] [Indexed: 01/15/2024]
Abstract
PURPOSE We surveyed the treatment of acute spinal cord injuries in the UK and compared current practices with 10 years ago. METHODS A questionnaire survey was conducted amongst neurosurgeons, neuroanaesthetists, and neurointensivists that manage patients with acute spinal cord injuries. The survey gave two scenarios (complete and incomplete cervical spinal cord injuries). We obtained opinions on the speed of transfer, timing and aim of surgery, choice of anaesthetic, intraoperative monitoring, targets for physiological parameters, and drug treatments. RESULTS We received responses from 78.6% of UK units that manage acute spinal cord injuries (33 neurosurgeons, 56 neuroanaesthetists/neurointensivists). Most neurosurgeons operate within 12 h for incomplete (82%) and complete (64%) injuries. There is a significant shift from 10 years ago, when only 61% (incomplete) and 30% (complete) of neurosurgeons operated within 12 h. The preferred anaesthetic technique in 2022 is total intravenous anaesthesia (TIVA), used by 69% of neuroanaesthetists. Significantly more intraoperative monitoring is now used at least sometimes, including bispectral index (91%), non-invasive cardiac output (62%), and neurophysiology (73-77%). Methylprednisolone is no longer used by surgeons. Achieving at least 80 mmHg mean arterial blood pressure is recommended by 70% neurosurgeons, 62% neuroanaesthetists, and 75% neurointensivists. CONCLUSIONS Between 2012 and 2022, there was a paradigm shift in managing acute spinal cord injuries in the UK with earlier surgery and more intraoperative monitoring. Variability in practice persists due to lack of high-quality evidence and consensus guidelines.

Influence of the timing of surgery for cervical spinal cord injury without bone injury in the elderly: A retrospective multicenter study. J Orthop Sci 2024; 29:480-485. [PMID: 36720671 DOI: 10.1016/j.jos.2023.01.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 01/07/2023] [Accepted: 01/12/2023] [Indexed: 01/30/2023]
Abstract
BACKGROUND Although previous studies have demonstrated the advantages of early surgery for traumatic spinal cord injury (SCI), the appropriate surgical timing for cervical SCIs (CSCIs) without bone injury remains controversial. Here, we investigated the influence of relatively early surgery within 48 h of injury on the neurological recovery of elderly patients with CSCI and no bone injury. METHODS In this retrospective multicenter study, we reviewed data from 159 consecutive patients aged ≥65 years with CSCI without bone injury who underwent surgery in participating centers between 2010 and 2020. Patients were followed up for at least 6 months following CSCI. We divided patients into relatively early (≤48 h after CSCI, n = 24) and late surgery (>48 h after CSCI, n = 135) groups, and baseline characteristics and neurological outcomes were compared between them. Multivariate analysis was performed to identify factors associated with neurological recovery. RESULTS The relatively early surgery group demonstrated a lower prevalence of cardiac disease, poorer baseline American Spinal Injury Association (ASIA) impairment scale grade, and lower baseline ASIA motor score (AMS) than those of the late surgery group (P < 0.030, P < 0.001, and P < 0.001, respectively). Although the AMS was lower in the relatively early surgery group at 6 months following injury (P = 0.001), greater improvement in this score from baseline to 6-months post injury was observed (P = 0.010). Multiple linear regression analysis revealed that relatively early surgery did not affect postoperative improvement in AMS, rather, lower baseline AMS was associated with better AMS improvement (P < 0.001). Delirium (P = 0.006), pneumonia (P = 0.030), and diabetes mellitus (P = 0.039) negatively influenced postoperative improvement. CONCLUSIONS Although further validation by future studies is required, relatively early surgery did not show a positive influence on neurological recovery after CSCI without bone injury in the elderly.

Zheng R, Fan Y, Guan B, Fu R, Yao L, Wang W, Li G, Zhou Y, Chen L, Feng S, Zhou H. A critical appraisal of clinical practice guidelines on surgical treatments for spinal cord injury. Spine J 2023; 23:1739-1749. [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.

Abstract
Traumatic spinal cord injury (TSCI) is frequent. Timely diagnosis and treatment have reduced the mortality, but the long-term recovery of neurologic functions remains ominous. After TSCI, tissue bleeding, edema, and adhesions lead to an increase in the intraspinal pressure, further causing the pathophysiologic processes of ischemia and hypoxia and eventually accelerating the cascade of secondary spinal cord injury. Timely surgery with appropriate decompression strategies can reduce that secondary injury. However, disagreement about the safety and effectiveness of decompression surgery and the timing of surgery still exists. The level and severity of spinal cord injury do have an impact on the timing of surgery; therefore, TSCI subpopulations may benefit from early surgery. Early surgery perhaps has little effect on recovery from complete TSCI but might be of benefit in patients with incomplete injury. Early decompression should be considered in patients with incomplete cervical TSCI. Patient age should not be used as an exclusion criterion for early surgery. The best time point for early surgery is although influenced by the shortest duration to thoroughly examine the patient's condition and stabilize the patient's state. After the patient's condition is fully evaluated, we can perform the surgical modality of emergency myelotomy and decompression. Therefore, a number of conditions should be considered, such as standardized decompression methods, indications and operation timing to ensure the effectiveness and safety of early surgical intervention, and promotion of the functional recovery of residual nerve tissue.

Efficacy of early versus delayed spinal cord decompression in neurological recovery after traumatic spinal cord injury: Systematic review and meta-analysis. Rev Esp Cir Ortop Traumatol (Engl Ed) 2023:S1888-4415(23)00200-X. [PMID: 37805026 DOI: 10.1016/j.recot.2023.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 09/19/2023] [Accepted: 09/21/2023] [Indexed: 10/09/2023] Open
Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To compare early (<24h) versus late (>24h) spinal cord decompression on neurological recovery in patients with acute spinal cord injury. METHODS A systematic review was performed according to the PRISMA protocol to identify studies published up to December 2022. Prospective cohort studies and controlled trials comparing early versus delayed decompression on neurological recovery were included. Variables included number of patients, level of injury, treatment time, ASIA grade, neurological recovery, use of corticosteroids, and complications. For the meta-analysis, the «forest plot» graph was developed. The risk of bias of the included studies was assessed using the ROBINS-I22 and Rob223 tools. RESULTS Six of the seven studies selected for our review were included in the meta-analysis, with a total of 1188 patients (592 patients in the early decompression group and 596 in the delayed decompression group), the mean follow-up was 8 months, in 5 studies used methylprednisolone, the most reported complications were thromboembolic cardiopulmonary events. Five studies showed significant differences in favor of early decompression (risk difference 0.10, 95% confidence interval 0.07-0.14, heterogeneity 46%). The benefit was greatest in cervical and incomplete injuries. CONCLUSION There is scientific evidence to recommend early decompression in the first 24h after traumatic spinal cord injury, as it improves final neurological recovery, and it should be recommended whenever the patient and hospital conditions allow it to be safely done.

Abstract
Acute traumatic spinal cord injury (tSCI) is a devastating occurrence that significantly contributes to global morbidity and mortality. Surgical decompression with stabilization is the most effective way to minimize the damaging sequelae that follow acute tSCI. In recent years, strong evidence has emerged that supports the rationale that early surgical intervention, within 24 h following the initial injury, is associated with a better prognosis and functional outcomes. In this review, we have summarized the evidence and elaborated on the nuances of this concept. Additionally, we have reviewed further concepts that stem from "time is spine," including earlier cutoffs less than 24 h and the challenging entity of central cord syndrome, as well as the emerging concept of adequate surgical decompression. Lastly, we identify barriers to early surgical care for acute tSCI, a key aspect of spine care that needs to be globally addressed via research and policy on an urgent basis.

Abstract
Aims Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age. Methods Patients aged ≥ 18 years with a traumatic CCS between January 2012 and December 2017 in Wales were identified. Patient demographics and data about injury, management, and outcome were collected. Statistical analysis was performed to assess mortality and between-group differences. Results A total of 65 patients were identified (66.2% male (n = 43), mean age 63.9 years (SD 15.9)). At a minimum of five years' follow-up, 32.3% of CCS patients (n = 21) had died, of whom six (9.2%) had died within 31 days of their injury. Overall, 69.2% of patients (n = 45) had been managed conservatively. There was no significant difference in age between conservatively and surgically managed patients (p = 0.062). Kaplan-Meier analysis revealed no significant difference in mortality between patients managed conservatively and those managed surgically (p = 0.819). However, there was a significant difference in mortality between the different age groups (< 50 years vs 50 to 70 years vs > 70 years; p = 0.001). At five years' follow-up, 55.6% of the patient group aged > 70 years at time of injury had died (n = 15). Respiratory failure was the most common cause of death (n = 9; 42.9%). Conclusion Almost one-third of patients with a traumatic CCS in Wales had died within five years of their injury. The type of management did not significantly affect mortality but their age at the time of injury did. Further work to assess the long-term functional outcomes of surviving patients is needed to generate more reliable prognostic information.

Abstract
PURPOSE Acute traumatic central cord syndrome (ATCCS) accounts for up to 70% of incomplete spinal cord injuries, and modern improvements in surgical and anaesthetic techniques have given surgeons more treatment options for the ATCCS patient. We present a literature review of ATCCS, with the aim of elucidating the best treatment option for the varying ATCCS patient characteristics and profiles. We aim to synthesise the available literature into a simple-to-use format to aid in the decision-making process. METHODS The MEDLINE, EMBASE, CENTRAL, Web of Science and CINAHL databases were searched for relevant studies and improvement in functional outcomes were calculated. To allow for direct comparison of functional outcomes, we chose to focus solely on studies which utilised the ASIA motor score and improvements in ASIA motor score. RESULTS A total of 16 studies were included for review. There were a total of 749 patients, of which 564 were treated surgically and 185 were treated conservatively. There was a significantly higher average motor recovery percentage amongst surgically-treated patients as compared to conservatively treated patients (76.1% vs. 66.1%, p value = 0.04). There was no significant difference between the ASIA motor recovery percentage of patients treated with early surgery and delayed surgery (69.9 vs. 77.2, p value = 0.31). Delayed surgery after a trial of conservative management is also an appropriate treatment strategy for certain patients, and the presence of multiple comorbidities portend poor outcomes. We propose a score-based approach to decision making in ATCCS, by allocating a numerical score for the patient's clinical neurological condition, imaging findings on CT or MRI, history of cervical spondylosis and comorbidity profile. CONCLUSIONS An individualised approach to each ATCCS patient, considering their unique characteristics will lead to the best outcomes, and the use of a simple scoring system, can aid clinicians in choosing the best treatment for ATCCS patients.

Abstract
Objective To evaluate the efficacy of the posterior hybrid technique (PHT) for the treatment of traumatic cervical spinal cord injury without vertebral fracture or dislocation with high signal intensity on T2WI (CSCIH). Methods A comparative analysis of clinical efficacy between CSCIH patients who underwent anterior decompression and fusion (ADF) surgery and those who underwent PHT surgery was retrospectively conducted. Demographic characteristics, cervical range of motion (CRM), cross-sectional area of spinal cord (CSASC), spinal canal area residual rate (SCARR), high signal intensity ratio (HSIR), Cervical Japanese Orthopedic Association (CJOA) score, and neck disability index (NDI) were assessed. Results Forty-three CSCIH cases with PHT and 46 CSCIH cases with ADF were collected from January 2013 to January 2017. The CRM in patients with PHT was superior to that in patients with ADF at the final follow-up (64.21 ± 18.46° vs. 48.71 ± 19.34°, p = 0.0002). The SCARR also showed greater improvements in the PHT group than in the ADF group (final follow-up: 93.54 ± 11.09% vs. 88.13 ± 10.84%, p = 0.022). Both groups indicated significant improvements in the CSASC and HSIR (p < 0.05); however, no significant differences were observed between the two groups. All patients showed improvements in the CJOA score and the NDI after surgery (p < 0.05). At the 6-month follow-up, the ADF group had better NDI scores than the PHT group (31.17 ± 10.42 vs. 36.78 ± 9.65, p = 0.010), whereas the PHT group exhibited better improvements than the ADF group at the final follow-up (66.86 ± 9.28% vs. 57.67 ± 10.22%, p < 0.0001). Conclusion The PHT was as effective as ADF in the treatment of CSCIH, whereas the PHT was superior in the improvement of patients' health-related quality of life and in CRM preservation during the long-term follow-up.

Abstract
Objective The objective of the present study was to evaluate the current practice in terms of timing to surgery in acute spinal cord injury (ASCI) patients among spinal surgeons from Iberolatinoamerican countries. Methods A descriptive cross-sectional study design as a questionnaire was sent by an email for all members of the Sociedad Ibero Latinoamericana de Columna (SILACO, in the Spanish acronym) and associated societies. Results A total of 162 surgeons answered questions related to the timing for surgery. Sixty-eight (42.0%) considered that ASCI with complete neurology injury should be treated within 12 hours, 54 (33.3%) performed early decompression within 24 hours, and 40 (24,7%) until the first 48 hours. Regarding ASCI with incomplete neurological injury, 115 (71.0%) would operate in the first 12 hours. There was a significant difference in the proportion of surgeons that would operate ASCI within ≤ 24 hours, regarding the type of injury (complete injury:122 versus incomplete injury:155; p < 0.01). In the case of patients with central cord syndrome without radiological evidence of instability, 152 surgeons (93.8%) would perform surgical decompression: 1 (0.6%) in the first 12 hours, 63 (38.9%) in 24 hours, 4 (2.5%) in 48 hours, 66 (40.7%) in the initial hospital stay, and 18 (11.1%) after neurologic stabilization. Conclusion All inquired surgeons favour early decompression, with the majority performing surgery in the first 24 hours. Decompression is performed earlier in cases of incomplete than in complete injuries. In cases of central cord syndrome without radiological evidence of instability, there is a tendency towards early surgical decompression, but the timing is still extremely variable. Future studies are needed to identify the ideal timing for decompression of this subset of ASCI patients.

Abstract
Initial treatment of traumatic spinal cord injury remains as controversial in 2023 as it was in the early 19th century, when Sir Astley Cooper and Sir Charles Bell debated the merits or otherwise of surgery to relieve cord compression. There has been a lack of high-class evidence for early surgery, despite which expeditious intervention has become the surgical norm. This evidence deficit has been progressively addressed in the last decade and more modern statistical methods have been used to clarify some of the issues, which is demonstrated by the results of the SCI-POEM trial. However, there has never been a properly conducted trial of surgery versus active conservative care. As a result, it is still not known whether early surgery or active physiological management of the unstable injured spinal cord offers the better chance for recovery. Surgeons who care for patients with traumatic spinal cord injuries in the acute setting should be aware of the arguments on all sides of the debate, a summary of which this annotation presents.

Abstract
The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months. The final analyses comprised 159 patients in the early and 135 in the late group. Patients in the early group had significantly more severe neurological impairment before surgical treatment. For unadjusted complete-case analysis, mean change in LEMS was 15.6 (95% confidence interval (CI) 12.1 to 19.0) in the early and 11.3 (95% CI 8.3 to 14.3) in the late group, with a mean between-group difference of 4.3 (95% CI -0.3 to 8.8). Using multiply imputed data adjusting for baseline LEMS, baseline ASIA Impairment Scale (AIS), and propensity score, the mean between-group difference in the change in LEMS decreased to 2.2 (95% CI -1.5 to 5.9). Compared to late surgical decompression, early surgical decompression following acute tSCI did not result in statistically significant or clinically meaningful neurological improvements 12 months after injury. These results, however, do not impact the well-established need for acute, non-surgical tSCI management. This is the first study to highlight that a combination of baseline imbalances, ceiling effects, and loss to follow-up rates may yield an overestimate of the effect of early surgical decompression in unadjusted analyses, which underpins the importance of adjusted statistical analyses in acute tSCI research.

Abstract
OBJECTIVE Acute traumatic spinal cord injury (tSCI) is followed by a prolonged period of secondary neuroglial cell death. Neuroprotective interventions, such as surgical spinal cord decompression, aim to mitigate secondary injury. In this study, the authors explore whether the effect size of posttraumatic neuroprotective spinal cord decompression varies with injury severity. METHODS Seventy-one adult female Long Evans rats were subjected to a thoracic tSCI using a third-generation spinal contusion device. Moderate and severe tSCI were defined by recorded impact force delivered to the spinal cord. Immediately after injury (< 15 minutes), treatment cohorts underwent either a decompressive durotomy or myelotomy. Functional recovery was documented using the Basso, Beattie, and Bresnahan locomotor scale, and tissue sparing was documented using histological analysis. RESULTS Moderate and severe injuries were separated at a cutoff point of 231.8 kdyn peak impact force based on locomotor recovery at 8 weeks after injury. Durotomy improved hindlimb locomotor recovery 8 weeks after moderate trauma (p < 0.01), but not after severe trauma (p > 0.05). Myelotomy led to increased tissue sparing (p < 0.0001) and a significantly higher number of spared motor neurons (p < 0.05) in moderate trauma, but no such effect was noted in severely injured rats (p > 0.05). Within the moderate injury group, myelotomy also resulted in significantly more spared tissue when compared with durotomy-only animals (p < 0.01). CONCLUSIONS These results suggest that the neuroprotective effects of surgical spinal cord decompression decrease with increasing injury severity in a rodent tSCI model.

Abstract
OBJECTIVE This study aims to evaluate the rate of improvement in neurologic recovery of patients with sports-related spinal cord injury (SRSCI) who had surgical intervention (SS) and those who did not (NSS). We aimed to 1) evaluate the rate of American Spinal Injury Association (ASIA) conversion in patients with and without surgery, and 2) assess predictors of conversion in ASIA grade. METHODS The National Spinal Cord Injury Model Systems Database (SCIMS) was used from 1973 to 2016. Patients with SRSCI were included. The primary outcome was rate of conversion in ASIA grade. Multivariate logistic regression was performed with separate subgroup analysis on patients with cervical injury (represented by odds ratio [OR]; 95% confidence interval [CI]). RESULTS A total of 1647 patients had SRSCI with 1502 (91%) SSs. Most patients (88%) were male, white (87%), and between the ages of 15 and 29 years (63%). Patients undergoing SS had significantly longer inpatient rehabilitation length of stay (LOS) (P < 0.001) and a more patients undergoing SS had complete motor or sensory loss compared with the NSS group. Multivariate logistic regression showed that injury at the thoracic level (OR, 0.41; 95% CI, 0.21-0.78), age 15-29 years (OR, 0.44; 95% CI, 0.20-0.97]), water-based injury (OR, 0.45; 95% CI, 0.21-0.95), and ASIA impairment grades of B, C, and D at admission were significantly associated with ASIA SCORE conversion. CONCLUSIONS We found that patients undergoing SS had longer LOS and a higher prevalence of complete injuries. Surgical intervention was not associated with conversion in ASIA grade to an improved status at time of discharge in a large cohort of patients with SRSCI and in a subcohort of patients with cervical SRSCI.

Abstract
OBJECTIVE The burden of spinal trauma in low- and middle-income countries (LMICs) is immense, and its management is made complex in such resource-restricted settings. Algorithmic evidence-based management is cost-prohibitive, especially with respect to spinal implants, while perioperative care is work-intensive, making overall care dependent on multiple constraints. The objective of this study was to identify determinants of decision-making for surgical intervention, improvement in function, and in-hospital mortality among patients experiencing acute spinal trauma in resource-constrained settings. METHODS This study was a retrospective analysis of prospectively collected data in a cohort of patients with spinal trauma admitted to a tertiary referral hospital center in Dar es Salam, Tanzania. Data on demographic, clinical, and treatment characteristics were collected as part of a quality improvement neurotrauma registry. Outcome measures were surgical intervention, American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade improvement, and in-hospital mortality, based on existing treatment protocols. Univariate analyses of demographic and clinical characteristics were performed for each outcome of interest. Using the variables associated with each outcome, a machine learning algorithm-based regression nonparametric decision tree model utilizing a bootstrapping method was created and the accuracy of the three models was estimated. RESULTS Two hundred eighty-four consecutively admitted patients with acute spinal trauma were included over a period of 33 months. The median age was 34 (IQR 26-43) years, 83.8% were male, and 50.7% had experienced injury in a motor vehicle accident. The median time to hospital admission after injury was 2 (IQR 1-6) days; surgery was performed after a further median delay of 22 (IQR 13-39) days. Cervical spine injury comprised 38.4% of the injuries. Admission AIS grades were A in 48.9%, B in 16.2%, C in 8.5%, D in 9.5%, and E in 16.6%. Nearly half (45.1%) of the patients underwent surgery, 12% had at least one functional improvement in AIS grade, and 11.6% died in the hospital. Determinants of surgical intervention were age ≤ 30 years, spinal injury level, admission AIS grade, delay in arrival to the referral hospital, undergoing MRI, and type of insurance; admission AIS grade, delay to arrival to the hospital, and injury level for functional improvement; and delay to arrival, injury level, delay to surgery, and admission AIS grade for in-hospital mortality. The best accuracies for the decision tree models were 0.62, 0.34, and 0.93 for surgery, AIS grade improvement, and in-hospital mortality, respectively. CONCLUSIONS Operative intervention and functional improvement after acute spinal trauma in this tertiary referral hospital in an LMIC environment were low and inconsistent, which suggests that nonclinical factors exist within complex resource-driven decision-making frameworks. These nonclinical factors are highlighted by the authors' results showing clinical outcomes and in-hospital mortality were determined by natural history, as evidenced by the highest accuracy of the model predicting in-hospital mortality.

Abstract
Background Severe traumatic cervical spinal cord injury (tcSCI) is a disastrous event for patients and families. Maximizing spinal cord function recovery has become the primary therapeutic goal. This study investigated the effect of early extensive posterior decompression on spinal cord function improvement after severe tcSCI. Methods A retrospective review of 83 consecutive patients who underwent extensive open-door laminoplasty decompression within 24 h after severe tcSCI (American Spinal Injury Association (ASIA) impairment scale (AIS) grade A to C) between 2009 and 2017 at our institution was performed. The patient clinical and demographic data were collected. Neurological functional recovery was evaluated according to the Japanese Orthopaedic Association (JOA) score system, ASIA motor score (AMS) and AIS grade. Results Among the 83 patients initially included, the baseline AIS grade was A in 12, B in 28, and C in 43. Twenty-three patients (27.7%) had a high cervical injury. Cervical spinal stenosis (CSS) was identified in 37 patients (44.6%). The mean intramedullary lesion length was 59.6 ± 20.4 mm preoperatively and 34.2 ± 13.3 mm postoperatively (p < 0.0001). At the final follow-up visit, an improvement of at least one and two AIS grades was found in 75 (90.4%) and 41 (49.4%) patients, respectively. 24 (64.9%) patients with an improvement of least two AIS grades had CSS. The mean AMS and JOA score were significantly improved at discharge and the final follow-up visit compared with on admission (p < 0.0001). Conclusions Our results suggest that early expansive laminoplasty decompression may improve neurological outcomes after severe tcSCI, especially in patients with CSS. Larger and prospective controlled studies are needed to validate these findings.

Abstract
BACKGROUND Traumatic cervical spinal cord injury (TCSCI) is a disabling condition with uncertain neurologic recovery. Clinical and preclinical studies have suggested early surgical decompression and other measures of neuroprotection improve neurologic outcome. We investigated the role of intramedullary lesion length (IMLL) on preoperative magnetic resonance imaging (MRI) and the effect of early cervical decompressive surgery on ASIA impairment scale (AIS) grade improvement following TCSCI. METHODS In this retrospective study, we investigated 34 TCSCI patients who were admitted over a 12-year period, from January 1, 2008 to January 31, 2020. We studied the patient demographics, mode of injury, IMLL and timing of surgical decompression. The IMLL is defined as the total length of edema and contusion/hemorrhage within the cord. Short tau inversion recovery (STIR) sequences or T2-weighted MR imaging with fat saturation increases the clarity of edema and depicts abnormalities in the spinal cord. All patients included had confirmed adequate spinal cord decompression with cervical fixation and a follow-up of at least 6 months. RESULTS Of the 34 patients, 16 patients were operated on within 24 hours (early surgery group) and 18 patients were operated on more than 24 hours after trauma (delayed surgery group). In the early surgery group, 13 (81.3%) patients had improvement of at least one AIS grade, whereas in the delayed surgery group, AIS grade improvement was seen in only in 8 (44.5%) patients (early vs. late surgery; odds ratio [OR] = 1.828; 95% confidence interval [CI]: 1.036-3.225). In multivariate regression analysis coefficients, the timing of surgery and intramedullary edema length on MRI were the most significant factors in improving the AIS grade following cervical SCI. Timing of surgery as a unique variance predicted AIS grade improvement significantly (p < 0.001). The mean IMLL was 41.47 mm (standard deviation [SD]: 18.35; range: 20-87 mm). IMLL was a predictor of AIS grade improvement on long-term outcome in bivariate analysis (p < 0.001). This study suggests that patients who had IMLL of less than 30 mm had a better chance of grade conversion irrespective of the timing of surgery. Patients with an IMLL of 31 to 60 mm had chances of better grade conversion after early surgery. A longer IMLL predicts lack of improvement (p < 0.05). If the IMLL is greater than 61 mm, the probability of nonconversion of AIS grade is higher, even if the patient is operated on within 24 hours of trauma. CONCLUSION Surgical decompression within 24 hours of trauma and shorter preoperative IMLL are significantly associated with improved neurologic outcome, reflected by better AIS grade improvement at 6 months' follow-up. The IMLL on preoperative MRI can reliably predict outcome after 6 months. The present study suggests that patients have lesser chances of AIS grade improvement when the IMLL is ≥61 mm.

Abstract
BACKGROUND Few data on the management of acute phase of traumatic spinal cord injury (tSCI) in patients suffering polytrauma are available. As the therapeutic choices in the first hours may have a deep impact on outcome of tSCI patients, we conducted an international survey investigating this topic. METHODS The survey was composed of 29 items. The main endpoints of the survey were to examine: (1) the hemodynamic and respiratory management, (2) the coagulation management, (3) the timing of magnetic resonance imaging (MRI) and spinal surgery, (4) the use of corticosteroid therapy, (5) the role of intraspinal pressure (ISP)/spinal cord perfusion pressure (SCPP) monitoring and (6) the utilization of therapeutic hypothermia. RESULTS There were 171 respondents from 139 centers worldwide. A target mean arterial pressure (MAP) target of 80-90 mmHg was chosen in almost half of the cases [n = 84 (49.1%)]. A temporary reduction in the target MAP, for the time strictly necessary to achieve bleeding control in polytrauma, was accepted by most respondents [n = 100 (58.5%)]. Sixty-one respondents (35.7%) considered acceptable a hemoglobin (Hb) level of 7 g/dl in tSCI polytraumatized patients. An arterial partial pressure of oxygen (PaO2) of 80-100 mmHg [n = 94 (55%)] and an arterial partial pressure of carbon dioxide (PaCO2) of 35-40 mmHg [n = 130 (76%)] were chosen in most cases. A little more than half of respondents considered safe a platelet (PLT) count > 100.000/mm3 [n = 99 (57.9%)] and prothrombin time (PT)/activated partial thromboplastin time (aPTT) < 1.5 times the normal control [n = 85 (49.7%)] in patients needing spinal surgery. MRI [n = 160 (93.6%)] and spinal surgery [n = 158 (92.4%)] should be performed after intracranial, hemodynamic, and respiratory stabilization by most respondents. Corticosteroids [n = 103 (60.2%)], ISP/SCPP monitoring [n = 148 (86.5%)], and therapeutic hypothermia [n = 137 (80%)] were not utilized by most respondents. CONCLUSIONS Our survey has shown a great worldwide variability in clinical practices for acute phase management of tSCI patients with polytrauma. These findings can be helpful to define future research in order to optimize the care of patients suffering tSCI.

Risk Factors for Poor Prognosis of Spinal Cord Injury without Radiographic Abnormality Associated with Cervical Ossification of the Posterior Longitudinal Ligament. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1572341. [PMID: 35224091 PMCID: PMC8872685 DOI: 10.1155/2022/1572341] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 02/04/2022] [Indexed: 01/16/2023]
Abstract
Purpose To investigate the factors associated with the prognosis of spinal cord injury without radiographic abnormality (SCIWORA) accompanied by cervical ossification of the posterior longitudinal ligament (C-OPLL). Methods We retrospectively investigated 287 patients with SCIWORA associated with C-OPLL, who were admitted within 30 days after trauma to our facility between August 2014 and August 2018. All patients were divided into the good or poor prognosis group. Patient demographics were analyzed. Besides, occupying ratio on CT and spinal cord high signal changes in MRI T2WI were measured and recorded. Multivariate linear regression was applied to analyze the correlation of prognosis with spinal cord high signal changes in MRI T2WI, cause of injury, and occupying ratio. Results Occupying ratio of ossification mass was 43.5 ± 10.7% in the poor prognosis group and 27.3 ± 7.7% in the good prognosis group. The occurrence rate of high signal changes in MRI T2WI was 84.2% in the poor prognosis group and 41.3% in the good prognosis group. Poor prognosis was correlated with high occupying ratio and spinal cord high signal changes in MRI T2WI. In the patient with SCIWORA associated with C-OPLL, ROC curve of occupying ratio showed 30% as a predictor for the poor prognosis. Among the 92 patients with occupying ratio ≤ 30%, poor prognosis was observed in 5 cases (5.4%), whereas in the 72 cases with occupying ratio > 30%, poor prognosis was seen in 33 cases (45.8%). Postoperative AIS grade at final follow-up in occupying ratio > 30% group was significantly worse. Conclusions Patients suffering from SCIWORA with C-OPLL have poor prognosis when they have higher occupying ratio of ossification mass and spinal cord high signal changes in MRI T2WI. The cut-off value of occupying ratio for predicting the poor prognosis was 30% in patients with SCIWORA associated with C-OPLL.

Abstract
PURPOSE To investigate the association of age with delay in spine surgery and the effects on neurological outcome after traumatic spinal cord injury (SCI). METHODS Ambispective cohort study (2011-2017) in n = 213 patients consecutively enrolled in a Level I trauma center with SCI care in a metropolitan region in Germany. Age-related differences in the injury to surgery interval and conditions associated with its delay (> 12 h after SCI) were explored using age categories or continuous variables and natural cubic splines. Effects of delayed surgery or age with outcome were analyzed using multiple logistic regression. RESULTS The median age of the study population was 58.8 years (42.0-74.6 IQR). Older age (≥ 75y) was associated with a prolonged injury to surgery interval of 22.8 h (7.2-121.3) compared to 6.6 h (4.4-47.9) in younger patients (≤ 44y). Main reasons for delayed surgery in older individuals were secondary referrals and multimorbidity. Shorter time span to surgery (≤ 12 h) was associated with higher rates of ASIA impairment scale (AIS) conversion (OR 4.22, 95%CI 1.85-9.65), as mirrored by adjusted spline curves (< 20 h 20-25%, 20-60 h 10-20%, > 60 h < 10% probability of AIS conversion). In incomplete SCI, the probability of AIS conversion was lower in older patients [e.g., OR 0.09 (0.02-0.44) for'45-59y' vs.' ≤ 44y'], as confirmed by spline curves (< 40y 20-80%, ≥ 40y 5-20% probability). CONCLUSION Older patient age complexifies surgical SCI care and research. Tackling secondary referral to Level I trauma centers and delayed spine surgery imposes as tangible opportunity to improve the outcome of older SCI patients.

Abstract
Secondary spinal cord changes can follow spinal cord injuries (SCIs). This retrospective study was to uncover the chronic secondary changes that affect the spinal cord following severe injuries and to evaluate the influence of residual spinal deformity in the development of posttraumatic spinal cord changes. Fifty-eight patients (39 male, 19 female) with complete traumatic SCI and recent Magnetic resonance imaging (MRI) follow-up were reviewed retrospectively. A minimum of 2 years duration between trauma and MRI study was required (mean 2.9 years [2.1-4.7]). Two groups of patients were formed: with spinal deformity (and or spinal canal compromise) and without spinal deformity (and or spinal canal compromise). MRI of the injured spine demonstrated four major types of spinal cord changes; these are spinal cord atrophy, myelomalacia, syrinx, and focal cyst formation. The correlation of these changes to the presence of spinal deformity and or spinal canal compromise was also studied. Twenty-three patients (40%) of the studied population had more than 30° kyphosis and or 50% compromise of the spinal canal. Chronic spinal cord changes occurred in 25 patients (43%), 17 of these changes occurred in patients with spinal deformity and the remaining 8 occurred in patients without spinal deformity or canal compromise (p ≤ .05). The prevalence of spinal cord atrophy and focal cysts was significantly higher in patients with residual deformity and or spinal canal compromise (p ≤ .05). The authors recommend proper spinal cord decompression and fixation for patients with complete SCI to reduce the chance of secondary SCI.

Abstract
BACKGROUND The case of a 69-year-old patient with an acute traumatic central cord syndrome (ATCCS) with preexisting spinal stenosis raised a discussion over the question of conservative versus surgical treatment in the acute setting. We provide a literature overview on the management (conservative vs. surgical treatment) of ATCCS with preexisting spinal stenosis. METHODS We reviewed the literature concerning essential concepts for the management of ATCCS with spinal stenosis and cervical spinal cord injury. The data retrieved from these studies were applied to the potential management of an illustrative case report. RESULTS Not rarely has ATCCS an unpredictable neurologic course because of its dynamic character with secondary injury mechanisms within the cervical spinal cord in the early phase, the possibility of functional deterioration, and the appearance of a neuropathic pain syndrome during late follow-up. The result of the literature review favors early surgical treatment in ATCCS patients with preexisting cervical stenosis. CONCLUSION Reluctance toward aggressive and timely surgical treatment of ATCCS should at least be questioned in patients with preexisting spinal stenosis.

Abstract
BACKGROUND Acute traumatic central cord syndrome (ATCCS) is the most common form of spinal cord injury in the United States. Treatment remains controversial, which is a consequence of ATCCS having an inherently different natural history from conventional spinal cord injury, thus requiring a separate classification system. We devised a novel Central Cord Score (CCscore), which both guides treatment and tracks improvement over time with symptoms specific to ATCCS. METHODS Medical records of patients with a diagnosis of ATCCS were retrospectively reviewed at a single institution. The CCscore was devised based on signs, symptoms, and imaging findings we believed to be critical in assessing severity of ATCCS. Numeric values were assigned for distal upper extremity motor strength, upper extremity sensation, ambulatory status, magnetic resonance imaging cord signal, and urinary retention. RESULTS We identified 51 patients with follow-up data; there were 17 cases of mild injury (CCscore 1-5), 23 moderate cases (CCscore 6-10), and 11 severe cases (CCscore 11-15). Patients treated surgically had significantly greater improvement in upper extremity motor scores and total CCscore only up to 3 months. In terms of timing of surgery, patients treated <24 hours after injury had significantly improved upper extremity motor scores and overall CCscores at last follow-up of ≥3 months. CONCLUSIONS Based on these data and their alignment with past literature, the CCscore is able to objectively and specifically categorize the severity and outcome of ATCCS, which represents a step forward in the quest to determine the ultimate efficacy and timing of surgery for ATCCS.

Abstract
Substantial clinical data supports an association between superior neurological outcomes and early (within 24 hours) surgical decompression for those with traumatic cervical spinal cord injury (SCI). Despite this, much discussion persists around feasibility and safety of this time threshold, particularly for those with a complete cervical SCI. This study aims to assess clinical practices and the safety profile of early surgery across a large sample of North American trauma centers. Data was derived from the Trauma Quality Improvement Program database from 2010-2016. Adult patients with a complete cervical SCI (ASIA A) who underwent surgery were included. Patients were stratified into those receiving surgery at or before 24 hours and those receiving delayed intervention. Risk-adjusted variability in surgical timing across trauma centers was investigated using mixed-effects regression. In-hospital adverse events including mortality, major complications, and immobility-related complications were compared between groups after propensity score matching. 2,862 patients from 353 North American trauma centers were included. 1,760 (61.5%) underwent surgery within 24 hours. Case-mix and hospital-level characteristics explained only 6% of the variability in surgical timing both between-centers and within-centers. No significant differences in adverse events were identified between groups. These findings suggest a relatively large proportion of patients are not receiving surgery within the recommended timeframe, despite apparent safety. Moreover, patient and hospital-level characteristics explain little of the variability in time-to-surgery. Further knowledge translation is needed to increase the proportion of patients in whom surgery is performed before the 24-hour threshold so patients might reach their greatest potential for neurologic recovery.

Abstract
After acute traumatic spinal cord injury (SCI), the spinal cord can swell to fill the subarachnoid space and become compressed by the surrounding dura. In a porcine model of SCI, we performed a duraplasty to expand the subarachnoid space around the injured spinal cord and evaluated how this influenced acute intraparenchymal hemodynamic and metabolic responses, in addition to histological and behavioral recovery. Female Yucatan pigs underwent a T10 SCI, with or without duraplasty. Using microsensors implanted into the spinal cord parenchyma, changes in blood flow (ΔSCBF), oxygenation (ΔPO2), and spinal cord pressure (ΔSCP) during and after SCI were monitored, alongside metabolic responses. Behavioral recovery was tested weekly using the Porcine Injury Behavior Scale (PTIBS). Thereafter, spinal cords were harvested for tissue sparing analyses. In both duraplasty and non-animals, the ΔSCP increased ∼5 mm Hg in the first 6 h post-injury. After this, the SCP appeared to be slightly reduced in the duraplasty animals, although the group differences were not statistically significant after controlling for injury severity in terms of impact force. During the first seven days post-SCI, the ΔSCBF or ΔPO2 values were not different between the duraplasty and control animals. Over 12 weeks, there was no improvement in hindlimb locomotion as assessed by PTIBS scores and no reduction in tissue damage at the injury site in the duraplasty animals. In our porcine model of SCI, duraplasty did not provide any clear evidence of long-term behavioral or tissue sparing benefit after SCI.

Abstract
Traumatic spinal cord injury (tSCI) is a life-changing and potentially overwhelming event. The sudden disruption of the spinal cord's integrity necessitates rapid attention at a specialized medical center, and involves a multilateral collaboration between neurologists, spine surgeons, critical care physicians, and trauma specialists. Even with care under ideal conditions, many tSCI patients have significant disability that persists for the rest of their lives. However, recently, we have seen a proliferation in clinical and translational trials that offer the promise that new treatments may be available soon.

Abstract
STUDY DESIGN Large multicenter retrospective cohort study. OBJECTIVE The objective of this study was to analyze the effect of fusion timing on inpatient outcomes in a nationally representative population with thoracolumbar fracture and concurrent neurological injury. SUMMARY OF BACKGROUND DATA Among thoracolumbar trauma admissions, concurrent neurological injury is associated with greater long-term morbidity. There is little consensus on optimal surgical timing for these patients; previous investigations fail to differentiate thoracolumbar fracture with and without neurological injury. MATERIALS AND METHODS We analyzed 19,136 nonelective National Inpatient Sample cases (2004-2014) containing International Classifications of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes for closed thoracic/lumbar fracture with neurological injury and procedure codes for primary thoracolumbar/lumbosacral fusion, excluding open/cervical fracture. Timing classification from admission to fusion was same-day, 1-2-, 3-6-, and ≥7-day delay. Primary outcomes included in-hospital mortality, complications, and infection; secondary outcomes included total and postoperative length of stay and charges. Logistic regressions and generalized linear models with gamma distribution and log-link evaluated the effect of surgical timing on primary and secondary outcomes, respectively, controlling for age, sex, fracture location, fusion approach, multiorgan system injury severity score, and medical comorbidities. RESULTS Patients undergoing surgery ≤72 hours (n=12,845) had the lowest odds of in-hospital cardiac [odds ratio (OR)=0.595; 95% confidence interval (CI), 0.357-0.991] and respiratory complications (OR=0.495; 95% CI, 0.313-0.784) and infection (OR=0.615; 95% CI, 0.390-0.969). No differences were observed between same-day (n=4724) and 1-2-day delay (n=8121) (P>0.05). Lowest odds of hemorrhage or hematoma was observed following 3-6-day delay (OR=0.467; 95% CI, 0.236-0.922). A ≥7-day delay to fusion (n=2,002) was associated with greatest odds of hemorrhage/hematoma (OR=2.019; 1.107-3.683), respiratory complications (OR=1.850; 95% CI, 1.076-3.180), and infection (OR=3.155; 95% CI, 1.891-5.263) and greatest increases in mean postoperative length of stay (4.26% or 35.3% additional days) and charges (163,562 or 71.7% additional US dollars) (P<0.001). CONCLUSIONS Patients with thoracolumbar fracture and associated neurological injury who underwent surgery within 3 days of admission experienced fewer in-hospital complications. These benefits may be due to secondary injury mechanism avoidance and earlier mobilization. LEVEL OF EVIDENCE Level III.

Abstract
The therapeutic significance of timing of decompression in acute traumatic central cord syndrome (ATCCS) caused by spinal stenosis remains unsettled. We retrospectively examined a homogenous cohort of patients with ATCCS and magnetic resonance imaging (MRI) evidence of post-treatment spinal cord decompression to determine whether timing of decompression played a significant role in American Spinal Injury Association (ASIA) motor score (AMS) 6 months following trauma. We used the t test, analysis of variance, Pearson correlation coefficient, and multiple regression for statistical analysis. During a 19-year period, 101 patients with ATCCS, admission ASIA Impairment Scale (AIS) grades C and D, and an admission AMS of ≤95 were surgically decompressed. Twenty-four of 101 patients had an AIS grade C injury. Eighty-two patients were males, the mean age of patients was 57.9 years, and 69 patients had had a fall. AMS at admission was 68.3 (standard deviation [SD] 23.4); upper extremities (UE) 28.6 (SD 14.7), and lower extremities (LE) 41.0 (SD 12.7). AMS at the latest follow-up was 93.1 (SD 12.8), UE 45.4 (SD 7.6), and LE 47.9 (SD 6.6). Mean number of stenotic segments was 2.8, mean canal compromise was 38.6% (SD 8.7%), and mean intramedullary lesion length (IMLL) was 23 mm (SD 11). Thirty-six of 101 patients had decompression within 24 h, 38 patients had decompression between 25 and 72 h, and 27 patients had decompression >72 h after injury. Demographics, etiology, AMS, AIS grade, morphometry, lesion length, surgical technique, steroid protocol, and follow-up AMS were not statistically different between groups treated at different times. We analyzed the effect size of timing of decompression categorically and in a continuous fashion. There was no significant effect of the timing of decompression on follow-up AMS. Only AMS at admission determined AMS at follow-up (coefficient = 0.31; 95% confidence interval [CI]:0.21; p = 0.001). We conclude that timing of decompression in ATCCS caused by spinal stenosis has little bearing on ultimate AMS at follow-up.

Comparison of Early Surgical Treatment With Conservative Treatment of Incomplete Cervical Spinal Cord Injury Without Major Fracture or Dislocation in Patients With Pre-existing Cervical Spinal Stenosis. Clin Spine Surg 2021; 34:E141-E146.

Abstract
STUDY DESIGN This was a retrospective comparative study. OBJECTIVE The objective of this study was to evaluate the clinical outcomes of early surgical treatment (<24 h) and conservative treatment of incomplete cervical spinal cord injury (CSCI) without major fracture or dislocation in patients with pre-existing cervical spinal canal stenosis (CSCS). SUMMARY OF BACKGROUND DATA The relative benefits of surgery, especially early surgical treatment, and conservative treatment for CSCI without major fracture or dislocation in patients with pre-existing CSCS remain unclear. Animal models of CSCI have demonstrated that early surgical decompression immediately after the initial insult may prevent or reverse secondary injury. However, the clinical outcomes of early surgery for incomplete CSCI in patients with pre-existing CSCS are still unclear. MATERIALS AND METHODS The medical records and radiographic data of 54 patients admitted to our facility between 2005 and 2015 with American Spinal Injury Association (ASIA) impairment scale grade B or C and pre-existing CSCS without major fracture or dislocation were retrospectively reviewed. Thirty-three patients (mean age, 57.4±14.0 y) underwent early surgical treatment within 24 hours after initial trauma (S group), and 21 patients (mean age, 56.9±13.6 y) underwent conservative treatment (C group) performed by 2 spinal surgeons in accordance with their policies. The primary outcome was the degree of improvement in ASIA grade after 2 years. RESULTS During the 2-year follow-up period, higher percentages of patients in the S group than in the C group showed ≥1 grade (90.9% vs. 57.1%, P=0.0051) and 2 grade (30.3% vs. 9.5%) improvements in ASIA grade. Multivariate analysis showed that treatment type, specifically early surgical treatment, was the only factor significantly associated with ASIA grade improvement after 2 years (P=0.0044). CONCLUSIONS Early surgery yielded better neurological outcomes than conservative treatment in patients with incomplete CSCI without major fracture or dislocation and pre-existing CSCS.

Abstract
Over the past four decades, there have been progressive changes in the epidemiology of traumatic spinal cord injury (tSCI). We assessed trends in demographic and injury-related variables in traumatic cervical spinal cord injury (tCSCI) patients over an 18-year period at a single Level I trauma center. We included all magnetic resonance imaging-confirmed tCSCI patients ≥15 years of age for years 2001-2018. Among 1420 patients, 78.3% were male with a mean age 51.5 years. Etiology included falls (46.9%), motor vehicle collisions (MVCs; 34.2%), and sports injuries (10.9%). Median American Spinal Injury Association (ASIA) Motor Score (AMS) was 44, complete tCSCI was noted in 29.6% of patients, fracture dislocations were noted in 44.7%, and median intramedullary lesion length (IMLL) was 30.8 mm (complete injuries 56.3 mm and incomplete injuries 27.4 mm). Over the study period, mean age and proportion of falls increased (p < 0.001) whereas proportion attributable to MVCs and sports injuries decreased (p < 0.001). Incomplete injuries, AMS, and the proportion of patients with no fracture dislocations increased whereas complete injuries decreased significantly. IMLL declined (p = 0.17) and proportion with hematomyelia did not change significantly. In adjusted regression models, increase in age and decreases in prevalence of MVC mechanism and complete injuries over time remained statistically significant. Changes in demographic and injury-related characteristics of tCSCI patients over time may help explain the observed improvement in outcomes. Further, improved clinical outcomes and drop in IMLL may reflect improvements in initial risk assessment and pre-hospital management, advances in healthcare delivery, and preventive measures including public education.

Abstract
PURPOSE This study aims to assess the nerve function deficient recovery in surgically treated patients with cervical trauma with spinal cord injury (SCI) in chronic stage and figure out prognostic predictors of improvement in impairment and function. METHODS We reviewed the clinical and radiological data of 143 cervical SCI patients in chronic stage and divided into non-operative group (n = 61) and operative group (n = 82). The severity of neurological involvement was assessed using the ASIA motor score (AMS) and Functional Independence Measure Motor Score (FIM MS). The health-related quality of life was measured using the SF-36 questionnaire. Correspondence between the clinical and radiological findings and the neurological outcome was investigated. RESULTS At 2-year follow-up, surgery resulted in greater improvement in AMS and FIM MS than non-operative group. Regression analysis revealed that lower initial AMS (P = 0.000), longer duration after injury (P = 0.022) and injury above C4 level (P = 0.022) were factors predictive of lower final AMS. Longer duration (P = 0.020) and injury above C4 level (P = 0.010) were associated with a lower FIM MS. SF-36 scores were significantly lower in higher age (P = 0.015), female patients (P = 0.009) and patients with longer duration (P = 0.001). CONCLUSION It is reasonable to consider surgical decompression in patients with cervical SCI in chronic stage and persistent spinal cord compression and/or gross cervical instability. Initial AMS, longer duration, injury above C4 level, higher age and female patients are the five major relevant factors of functional recovery.

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.

The influence of timing of surgical decompression for acute spinal cord injury: a pooled analysis of individual patient data. Lancet Neurol 2020; 20:117-126. [PMID: 33357514 DOI: 10.1016/s1474-4422(20)30406-3] [Citation(s) in RCA: 154] [Impact Index Per Article: 38.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 10/19/2020] [Accepted: 10/21/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Although there is a strong biological rationale for early decompression of the injured spinal cord, the influence of the timing of surgical decompression for acute spinal cord injury (SCI) remains debated, with substantial variability in clinical practice. We aimed to objectively evaluate the effect of timing of decompressive surgery for acute SCI on long-term neurological outcomes. METHODS We did a pooled analysis of individual patient data derived from four independent, prospective, multicentre data sources, including data from December, 1991, to March, 2017. Three of these studies had been published; of these, only one study previously specifically analysed the effect of the timing of surgical decompression. These four datasets were selected because they were among the highest quality acute SCI datasets available and contained highly granular data. Individual patient data were obtained by request from study authors. All patients who underwent decompressive surgery for acute SCI within these datasets were included. Patients were stratified into early (<24 h after spinal injury) and late (≥24 h after spinal injury) decompression groups. Neurological outcomes were assessed by American Spinal Injury Association (ASIA), or International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), examination. The primary endpoint was change in total motor score from baseline to 1 year after spinal injury. Secondary endpoints were ASIA Impairment Scale (AIS) grade and change in upper-extremity motor, lower-extremity motor, light touch, and pin prick scores after 1 year. One-stage meta-analyses were done by hierarchical mixed-effects regression adjusting for baseline score, age, mechanism of injury, AIS grade, level of injury, and administration of methylprednisolone. Effect sizes were summarised by mean difference (MD) for sensorimotor scores and common odds ratio (cOR) for AIS grade, with corresponding 95% CIs. As a secondary analysis, change in total motor score was regressed against time to surgical decompression (h) as a continuous variable, using a restricted cubic spline with adjustment for the same covariates as in the primary analysis. FINDINGS We identified 1548 eligible patients from the four datasets. Outcome data at 1 year after spinal injury were available for 1031 patients (66·6%). Patients who underwent early surgical decompression (n=528) experienced greater recovery than patients who had late decompression surgery (n=1020) at 1 year after spinal injury; total motor scores improved by 23·7 points (95% CI 19·2-28·2) in the early surgery group versus 19·7 points (15·3-24·0) in the late surgery group (MD 4·0 points [1·7-6·3]; p=0·0006), light touch scores improved by 19·0 points (15·1-23·0) vs 14·8 points (11·2-18·4; MD 4·3 [1·6-7·0]; p=0·0021), and pin prick scores improved by 18·3 points (13·7-22·9) versus 14·2 points (9·8-18·6; MD 4·0 [1·5-6·6]; p=0·0020). Patients who had early decompression also had better AIS grades at 1 year after surgery, indicating less severe impairment, compared with patients who had late surgery (cOR 1·48 [95% CI 1·16-1·89]; p=0·0019). When time to surgical decompression was modelled as a continuous variable, there was a steep decline in change in total motor score with increasing time during the first 24-36 h after injury (p<0·0001); and after 36 h, change in total motor score plateaued. INTERPRETATION Surgical decompression within 24 h of acute SCI is associated with improved sensorimotor recovery. The first 24-36 h after injury appears to represent a crucial time window to achieve optimal neurological recovery with decompressive surgery following acute SCI. FUNDING None.

Rafter D, Vasdev R, Hurrelbrink D, Gormley M, Chettupally T, Shen FX, Samadani U. Litigation risks despite guideline adherence for acute spinal cord injury: time is spine. Neurosurg Focus 2020; 49:E17. [PMID: 33130619 DOI: 10.3171/2020.8.focus20607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 08/18/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Current guidelines do not specify timing for management of acute spinal cord injury (aSCI) due to lack of high-quality evidence supporting specific intervals for intervention. Randomized prospective trials may be unethical. Nonetheless, physicians have been sued for delays in diagnosis and intervention. METHODS The authors reviewed both the medical literature supporting the guidelines and the legal cases reported in the Westlaw and Lexis Advance databases from 1972 to 2018 resulting in awards or settlements, to identify whether surgeons are vulnerable to litigation despite the existence of guidelines not mandating specific timing of care. RESULTS Timing of intervention was related to claims in 59 (36%) of 163 cases involving SCI. All 22 trauma cases identified cited timing of intervention, sometimes related to delayed diagnosis, as a reason for the lawsuit. The mean award of 10 cases in which the plaintiffs' awards were disclosed was $4,294,384. In the majority of cases, award amounts were not disclosed. CONCLUSIONS Because conduct of a prospective, randomized trial to investigate surgical timing of intervention for aSCI may not be achievable, evidence-based guidelines will be unlikely to mandate specific timing. Nonetheless, surgeons who unreasonably delay intervention for aSCI may be at risk for litigation due to treatment delay. This is increasingly likely in an environment where "complete" SCI is difficult to verify. SCI may at some point be recognized as a surgical emergency, as brain injury generally is, despite a lack of prospective randomized trials supporting this implementation, challenging the feasibility of the US trauma infrastructure to provide care for these patients.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE We aimed to evaluate the improvement in neurological deficit following early versus late decompression and stabilization of thoracolumbar junctional fractures. METHODS This is a retrospective evaluation of all patients with a traumatic spinal cord injury (SCI) from T11 to L2 treated at a teaching hospital between 2010 and 2017. Grouped analysis was performed comparing the cohort of patients who received early surgery within 24 hours (group 1) with those operated within 24 to 72 hours (group 2) and more than 72 hours after SCI (group 3). The primary outcome was the change in ASIA (American Spinal Injury Association) motor score at 12-month follow-up. RESULTS There were 317 patients (225 males and 92 females with mean age of 31.55 ± 12.43 years). A total of 144, 77, and 96 patients belonged to groups 1, 2, and 3 respectively. Improvement of at least 1 grade on ASIA classification was observed in 80, 45, and 33 patients in groups 1, 2, and 3 respectively (P = .001). Overall, 32, 12, and 10 patients improved ≥2 grades on ASIA classification in groups 1, 2, and 3, respectively (P = .069). On logistic regression analysis, early surgery and severity of initial injury (complete [ASIA A] vs incomplete SCI [ASIA B-D]) were found to significantly influence the potential for neurologic improvement (P = .004 and P < .0001, respectively). CONCLUSION We believe that the earlier the decompression, the better. The 72-hour cutoff represents the most promising time window during which surgical decompression has the potential to confer a neuroprotective effect in the setting of incomplete SCI (ASIA B-D) in the distal region of the spinal cord (conus medullaris).

Abstract
Increased mechanical stress after spinal cord injury (SCI) expands the scope of nerve tissue damage and exacerbates nerve function defects. Surgical decompression after SCI is a conventional therapeutic strategy and has been proven to have neuroprotective effects. However, the mechanisms of the interaction between mechanical stress and neurons are currently unknown. In this study, we monitored intramedullary pressure (IMP) and investigated the therapeutic benefit of decompression (including durotomy and piotomy) after injury and its underlying mechanisms in SCI. We found that decreased IMP promotes the generation and degradation of LC3 II, promotes the degradation of p62 and enhances autophagic flux to alleviate apoptosis. The lysosomal dysfunction was reduced after decompression. Piotomy was better than durotomy for the histological repair of spinal cord tissue after SCI. However, the autophagy‐lysosomal pathway inhibitor chloroquine (CQ) partially reversed the apoptosis inhibition caused by piotomy after SCI, and the structural damage was also aggravated after CQ administration. An antibody microarray analysis showed that decompression may reverse the up‐regulated abundance of p‐PI3K, p‐AKT and p‐mTOR caused by SCI. Our findings may contribute to a better understanding of the mechanism of decompression and the effects of mechanical stress on autophagy after SCI.

Abstract
OBJECTIVE The objective of this review is to synthesize and consolidate the existing literature on the treatment of SCI, focusing on drugs in development and cellular therapeutics, including stem-cell treatments. METHODS Studies were identified through a systemic search of PubMed, Ovid MEDLINE, Embase and the Cochrane database from their respective inceptions through January 1, 2020. We used the keywords "spinal cord injuries", "therapeutics", "stem cells", and "pharmacology." STUDY SELECTION Studies that assessed treatment strategies for SCI were included. DATA EXTRACTION AND SYNTHESIS Data on SCIs were processed according to the Preferred Reporting Items for Systematic Reviews and meta-Analyses (PRISMA) guidelines. FINDINGS In total, 62 articles were found in the literature search and 13 clinical trials were identified and included in this study. This review article discusses the management and treatment of SCI with an emphasis on the pharmacology, molecular approaches, and the use of stem cells. Presently, none of the treatments examined has shown to be clearly effective. CONCLUSIONS Present management strategies of SCI are focused on improving spinal cord perfusion and decreasing secondary injuries such as hypoxia, inflammation, edema, excitotoxicity and disturbances of ion homeostasis. This review hopes to demonstrate the significant advances made in the field of SCI and the new methodologies and practices being employed by researchers to improve our knowledge of the pathology. Our hope is that by consolidating the past and current research, improvements can be made in the management, treatment, and outcomes for these patients and other who suffer from spinal pathologies.

Abstract
Retrospective single institution observational study.The aim of the present study was to analyze the influence of early extensive posterior decompression on complications in patients with severe traumatic cervical spinal cord injury (tcSCI).Cervical SCI is associated with a high prevalence of hyponatremia and cardiopulmonary dysfunction. However, very few studies have focused on this exploration to reduce the incidence of SCI early complications.We reviewed the medical records of consecutive patients undergoing extensive posterior decompression within 24 h for severe tcSCI (American Spinal Injury Association Impairment Scale [AIS] A to C) admitted between January 2009 and January 2018. The data collected retrospectively included age, gender, mechanism, and level of SCI, AIS grade, fracture or dislocation, electrolyte, and cardiopulmonary complications.Of the 97 enrolled patients, the baseline AIS grade was AIS A in 14, AIS B in 31, and AIS C in 52. Improvement of at least two AIS grades was found in 26 (26.8%), and improvement of at least one grade was found in 80.4% of patients at discharge. Twenty-nine (29.9%) patients had mild hyponatremia, 8 (8.2%) had moderate hyponatremia, and 3 (3.1%) had severe hyponatremia during hospitalization. The incidences of hyponatremia, hypotension, and tracheotomy were 41.2%, 13.4%, and 6.2%, respectively. The mean forced vital capacity (FVC) on admission and at discharge was 1.34 ± 0.46 L and 2.21 ± 0.41 L (P < .0001), respectively. Five patients developed pneumonia.Our results suggest that early expansive posterior decompression significantly reduces the incidence of hyponatremia, hypotension, and tracheotomy by promoting recovery of spinal cord function after severe tcSCI.

Abstract
Background: Traumatic cervical spine injuries (CSIs) can be defined as osteodiscoligamentous lesions and are frequent in the young and active population. These lesions are often associated with significant devastating neurological deficits. Here, we sought to establish short-and medium-term prognostic factors that could help predict future outcomes. Methods: We retrospectively reviewed 102 adults admitted for traumatic CSI over an 11-year period (January 2004–December 2014). Patients were graded using Frankel scale as exhibiting good or poor outcomes. Results: Two risk factors that significantly predicted results for CSI included original poor Frankel grades (e.g., A and B) and initial neurovegetative disorders (e.g., respectively, P = 0.019 and P = 0.001). However, we did not anticipate that two other risk factors, operative delay and mechanism of trauma, would not significantly adversely impact outcomes. Conclusion: Here, we identified two significant risk factors for predicting poor outcomes following CSI; poor initial Frankel Grades A and B and neurovegetative disorders at the time of original presentation.

Abstract
STUDY DESIGN Narrative review. OBJECTIVE There is a strong biological rationale to perform early decompression after traumatic spinal cord injury (SCI). With an enlarging clinical evidence base, most spine surgeons internationally now favor early decompression for the majority of SCI patients; however, a number of pertinent questions remain surrounding this therapy. METHODS A narrative review evaluating the status of early surgery for SCI. In particular, we addressed the following questions: (1) Which patients stand to benefit most from early surgery? 2) What is the most appropriate time threshold defining early surgery? RESULTS Although heterogeneity exists, the evidence generally seems to support early surgery. While the best evidence exists for cervical SCI, there is insufficient data to support a differential effect for early surgery depending on neurological level or injury severity. When comparing thresholds to define early versus late surgery-including a later threshold (48-72 hours), an earlier threshold (24 hours), and an ultra-early threshold (8-12 hours)-the 2 earlier time points seem to be associated with the greatest potential for improved outcomes. However, existing prehospital and hospital logistics pose barriers to early surgery in a significant proportion of patients. An overview of recommendations from the recent AOSpine guidelines is provided. CONCLUSION In spite of increasing acceptance of early surgery post SCI, further research is needed to (1) identify subgroups of patients who stand to derive particular benefit-in particular to develop more evidence-based approaches for central cord syndrome and (2) investigate the efficacy and feasibility of ultra-early surgery targeting more aggressive timelines.
