Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The purpose of the current study was to examine the effectiveness of late decompression surgery for traumatic cervical spinal cord injury (CSCI) with pre-existing cord compression. SETTING Murayama Medical Center, National Hospital Organization, Tokyo, Japan. METHODS In total 78 patients with traumatic CSCI without bone injury hospitalized in 2012-2015 in our institute for rehabilitation after initial emergency care were divided into four groups according to the compression rate (CR) of the injured level and whether or not decompression surgery was performed. Neurological status was evaluated by American Spinal Injury Association impairment scale (AIS), Barthel index, and Spinal Cord Independence Measure (SCIM). RESULTS In the severe compression group (CR ≥ 40%), >2 grade improvement in the AIS was observed in 30% of patients with surgical treatment, although it was not observed in any patient without surgery. The SCIM improvement rate at discharge was 60% in the surgical treatment group and 20% in the non-surgical treatment group. In the minor compression group (CR < 40%), >2 grade improvement in the AIS was observed in 18% of patients with surgical treatment and in 11% without surgery. The SCIM improvement rate at discharge was 52% in the surgical treatment group and 43% in the non-surgical treatment group. CONCLUSIONS These results indicate that surgical treatment has an advantage for patients following traumatic CSCI with severe cord compression. In contrast, surgical efficacy is not proved for CSCI patients without severe cord compression.

Abstract
Spinal cord injury is a rare disease with an incidence about 40 cases per million population in the USA. The most common reasons are traffic accidents, falls, violence and sports. A 53-year-old male patient presented with an incomplete tetraparesis as a result of a spinal cord injury after the accident. It was not possible to treat him with steroids because he was out of the therapeutic time period of 8 hours when he presented to the hospital. The main problem of spinal cord injuries is the secondary injury caused by inflammation and swelling of the spinal cord. To avoid this, the patient was experimentally treated with erythropoietin (EPO) intrathecal and EPO, granulocyte-colony-stimulating factor and vitamin C subcutaneous after his initial spinal cord relief surgery. These drugs might be able to relieve this secondary reaction but were never applied for this indication in human before. This study shows that it could be a promising treatment for spinal cord injuries with potential therapeutic benefits.

Abstract
BACKGROUND Evidence indicates that, over time, patients with spinal cord injury (SCI) improve neurologically in various degrees. We sought to further investigate indicators of grade conversion in cervical SCI. OBJECTIVE To detect predictors of ASIA impairment scale (AIS) grade conversion in SCI following surgical decompression. METHODS In a retrospective study, demographics, clinical, imaging, and surgical data from 100 consecutive patients were assessed for predictors of AIS grade conversion. RESULTS American Spinal Injury Association motor score was 17.1. AIS grade was A in 52%, B in 29%, and C in 19% of patients. Surgical decompression took place on an average of 17.6 h following trauma (≤12 h in 51 and >12 h in 49). Complete decompression was verified by magnetic resonance imaging (MRI) in 73 patients. Intramedullary lesion length (IMLL) on postoperative MRI measured 72.8 mm, and hemorrhage at the injury epicenter was noted in 71 patients. Grade conversion took place in 26.9% of AIS grade A patients, 65.5% of AIS grade B, and 78.9% of AIS grade C. AIS grade conversion had statistical relationship with injury severity score, admission AIS grade, extent of decompression, presence of intramedullary hemorrhage, American Spinal Injury Association motor score, and IMLL. A stepwise multiple logistic regression analysis indicated IMLL was the sole and strongest indicator of AIS grade conversion (odds ratio 0.950, 95% CI 0.931-0.969). For 1- and 10-mm increases in IMLL, the model indicates 4% and 40% decreases, respectively, in the odds of AIS grade conversion. CONCLUSION Compared with other surrogates, IMLL remained as the only predictor of AIS grade conversion.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE To conduct a systematic review and synthesis of the literature to assess the comparative effectiveness, safety, and cost-effectiveness of early (≤24 hours) versus late decompression (>24 hours) in adults with acute spinal cord injury (SCI). METHODS A systematic search was conducted of Medline, EMBASE, the Cochrane Collaboration Library, and Google Scholar to identify studies published through November 6, 2014. Studies published in any language, in humans, and with an abstract were considered for inclusion. Included studies were critically appraised and the overall strength of evidence was determined using methods proposed by the Grading of Recommendation Assessment, Development and Evaluation working group. RESULTS The search yielded 449 potentially relevant citations. Sixteen additional primary studies were identified through other sources. Six studies met inclusion criteria. All but 2 studies were considered to have moderately high risk of bias. Across studies and injury levels, the impact of early surgical decompression (≤24 hours) on clinically important improvement in neurological status was variable. Isolated studies reported statistically significant and clinically important improvements at 6 months (cervical injury, low strength of evidence) and following discharge from inpatient rehabilitation (all levels, very low strength of evidence) but not at other time points; another study observed a statistically significant 6 point improvement in ASIA Impairment Scale (AIS) among patients with AIS B, C, or D, but not for those with AIS A (very low strength of evidence). In one study of acute central cord syndrome without instability, a clinically and statistically meaningful improvement in total motor scores was reported at 6 and 12 months in patients treated early (versus late). There were, however, no significant differences in AIS improvement between early and late surgical groups at 6- or 12-months (very low strength of evidence). One of 3 studies found a shorter length of hospital stay associated with early surgical decompression. Of 3 studies reporting on safety, no significant differences in rates of complications (including mortality, neurologic deterioration, pneumonia or pressure ulcers) were noted between early and late decompression groups. CONCLUSIONS Results surrounding the efficacy of early versus late decompressive surgery, as well as the quality of evidence available, were variable depending on the level of SCI, timing of follow-up, and specific outcome considered. Existing evidence supports improved neurological recovery among cervical SCI patients undergoing early surgery; however, evidence regarding remaining SCI populations and clinical outcomes was inconsistent.

Abstract
The aim of this study was to highlight the walking recovery after surgical management of traumatic burst fractures at the thoracolumbar junction (T10 or T11 or T12 or L1) in paraplegic patients to decide what surgeons should tell their patients to help them develop realistic expectations and potentially improve their outcome. This is a series of adult patients presented with paraplegia from isolated thoracolumbar fracture and underwent surgical intervention from August 2009 to August 2015. Patients with preexisting disability from previous neurologic condition, patients with associated severe head injury or major medical comorbidities or life-threatening injuries were excluded. Neurological status was assessed on admission using the American Spinal Injury Association (ASIA) impairment scale (AIS). The walking ability was assessed 12 months after surgery using the modified Benzel scale. This study included 53 patients with a mean age of 39.4 years (ranging from 18 years to 58 years). Patients presented with AIS grade A are 6, 18 patients with AIS grade B, and 29 patients with AIS grade C. All the patients with L1 fracture and 70.96% of the patients with T12 fracture regained the ability to walk, but unfortunately all the patients with T10 and T11 fractures didn’t regain the walking ability 12 months after surgery. The severity of spinal cord injury and hence the walking recovery were related to the spinal level of fracture. A prospectively controlled study with more patients is needed to reevaluate the walking recovery in paraplegic patients with T10 and T11 fractures.

Abstract
BACKGROUND AND PURPOSE Acute markers of spinal cord injury are essential for both diagnostic and prognostic purposes. The goal of this study was to assess the relationship between early MR imaging biomarkers after acute cervical spinal cord injury and to evaluate their predictive validity of neurologic impairment. MATERIALS AND METHODS We performed a retrospective cohort study of 95 patients with acute spinal cord injury and preoperative MR imaging within 24 hours of injury. The American Spinal Injury Association Impairment Scale was used as our primary outcome measure to define neurologic impairment. We assessed several MR imaging features of injury, including axial grade (Brain and Spinal Injury Center score), sagittal grade, length of injury, maximum canal compromise, and maximum spinal cord compression. Data-driven nonlinear principal component analysis was followed by correlation and optimal-scaled multiple variable regression to predict neurologic impairment. RESULTS Nonlinear principal component analysis identified 2 clusters of MR imaging variables related to 1) measures of intrinsic cord signal abnormality and 2) measures of extrinsic cord compression. Neurologic impairment was best accounted for by MR imaging measures of intrinsic cord signal abnormality, with axial grade representing the most accurate predictor of short-term impairment, even when correcting for surgical decompression and degree of cord compression. CONCLUSIONS This study demonstrates the utility of applying nonlinear principal component analysis for defining the relationship between MR imaging biomarkers in a complex clinical syndrome of cervical spinal cord injury. Of the assessed imaging biomarkers, the intrinsic measures of cord signal abnormality were most predictive of neurologic impairment in acute spinal cord injury, highlighting the value of axial T2 MR imaging.

Abstract
AIM The study purpose was to present a clinical case of spinal stroke in a pregnant female, which was caused by an endodermal cyst of the cervical spinal cord, and to analyze treatment tactics. RESULTS A 20 week pregnant female presented with acute transverse spinal cord injury at the of C3-C5 spinal segment level. CT revealed an extramedullary space-occupying lesion in the ventrolateral position, with compression of the spinal cord at this level. The patient in the state of progressive deterioration with respiratory failure was transferred to the Neurosurgical Institute on the 5th day after disease onset. The patient underwent surgery on the 7th day after disease onset. Doctors of various specialties participated in preparation for surgery. During surgery, total resection of the space-occupying lesion and spinal cord decompression were performed. An obstetrician-gynecologist conducted intraoperative fetal monitoring by ultrasound. The histological diagnosis was an endodermal cyst. There was no improvement of neurological symptoms in the early postoperative period. After stabilization of the condition, the patient was discharged for follow-up care at the place of residence. According to the follow-up report, the patient underwent the cesarean section because of exacerbation of lung infection and a significant delay in the fetal development. After a few days, the patient died due to multiple organ failure. The child was alive, in serious condition, under mechanical ventilation. CONCLUSION In the case of spinal stroke, the decision on treatment tactics should be made no later than 12 hours after its onset; otherwise, the outcome is usually unfavorable, and a neurological deficit is irreversible. The decision about continuing pregnancy should be made individually in each case, and an approach to the choice of appropriate treatment tactics should be multi-disciplinary.

Abstract
BACKGROUND Treatment for spinal trauma is affected by both nonmodifiable and modifiable variables. The aim of this study was to compare early surgery with intermediate and late surgery to determine the benefits of spinal reconstruction in neurological recovery and functional restoration in patients with thoracolumbar fractures. METHODS In order to identify correlations between treatment timing, fracture site, neurological recovery, American Spinal Injury Association (ASIA) score restoration, and rehabilitation prognosis in patients with thoracic and lumbar fractures, we conducted a multivariate analysis of the results of surgery, at our institution, in 166 consecutive patients with unstable thoracolumbar fractures with or without neurological impairment. We conducted a literature review (1988-2012) and compared our results with those already published. RESULTS Regardless of the location and type of fracture, early surgery resulted in a reduction of median hospital and intensive care unit (ICU) length of stay, as well as a reduction of nosocomial complications. Regardless of the type of fracture and preoperative ASIA score, thoracic fractures had the worst outcome. Early treatment seemed to have better results, depending on the preoperative ASIA score. CONCLUSION Early surgery in patients with thoracolumbar fractures with incomplete neurological damage could positively affect neurological recovery, functional restoration, length of hospital and ICU stay, and associated comorbidity. Thoracic fractures had the worst outcome. Early surgery seemed to have better results if the initial ASIA score was good. The better the ASIA score on admission, the better was the outcome. Surgical timing did not affect the outcome when the ASIA score was A or E.

Abstract
Sub-axial cervical spine injuries are commonly seen in patients with blunt trauma. They may be associated with spinal cord injury resulting in tetraplegia and severe permanent disability. Immobilization of the neck, maintenance of blood pressure and oxygenation, rapid clinical and radiological assessment of all injuries, and realignment of the spinal column are the key steps in the emergency management of these injuries. The role of intravenous methylprednisolone administration in acute spinal cord injuries remains controversial. The definitive management of these injuries is based upon recognition of the fracture pattern, assessment of the degree of instability, the presence or absence of neurologic deficit, and other patient related factors that may influence the outcome. Nonoperative treatment comprises of some form of external immobilization for 8 to 12 weeks, followed by imaging to assess fracture healing, and to rule out instability. The goals of surgery are realignment of the vertebral column, decompression of the neural elements and instrumented stabilization.

Abstract
Background The proper timing for surgery in patients with acute spinal cord injury is controversial. This study was conducted to detect if there is an advantage in early (within the first 4 hours after trauma) compared to late (between 4 and 24 hours after trauma) surgery on neurological outcome. Methods In this single institution prospective cohort study, data were analyzed from 51 spinal cord injured patients with an average age of 43.4 (±19.2) years. The influence of early (29 patients within the first 4 hours) as opposed to late (22 patients between 4 and 24 hours) decompression was evaluated by comparing data for neurological outcome. Patients of the study collectively suffered acute spinal fractures from C2 to L3 (cervical 39.2%, thoracic 29.4%, and lumbal 21.6%) or nonosseous lesions (9.8%). American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades were assessed at time of admission and 6 months after trauma or longer depending on the time of release. Surgical treatment included early stabilization and decompression within 24 hours. Results No significant difference between improved neurological function, measured with the AIS, and an early or late surgery time can be seen (P=0.402). Furthermore, binary logistic regression shows no significant difference between sex or age, and AIS improvement as possible confounders. Conclusion In our study, all patients with spinal cord injury were treated with spine stabilization and decompression within the first 24 hours after trauma. Surgical decompression within the first 4 hours after trauma was not associated with improved neurological outcome compared to treatment between 4 and 24 hours. In a clinical context, this indicates that there is a time frame of at least 1 day in which optimal care is possible.

Abstract
Background Patient selection for surgical treatment of subaxial cervical spine fractures (S-CS-fx) may be challenging and is dependent on fracture morphology, the integrity of the discoligamentous complex, neurological status, comorbidity, risks of surgery and the expected long-term outcomes. The purpose of this study is to evaluate complications and long-term outcomes in a consecutive series of 303 patients with S-CS-fx treated with open surgical fixation. Methods Medical charts were retrospectively reviewed. The surviving patients participated in a prospective long-term follow-up, including clinical history, physical examination and updated cervical CT. Patients with ankylosing spondylitis were excluded from this study. Results The median patient age was 48 years (range 14.7–93.9), and 74 % were males. Preoperatively, 43 % had spinal cord injury (SCI), and 27 % exhibited isolated radiculopathy. The median time from injury to surgery was 2 days (range 0–136). The risks of SCI deterioration and new-onset radiculopathy after surgery were 2.0 % and 1.3 %, respectively. Surgical mortality (death within 30 days after surgery) was 2.3 %. The reoperation rate was 7.3 %. At the long-term follow-up conducted a median of 2.6 years after trauma (range 0.5–9.1), 256 (99.2 %) of the patients who had survived and were living in Norway participated. Of the patients with American Injury Severity Scale (AIS) A–D at presentation, 51 % had improved one or more AIS grades. At the time of follow-up, 89 % of the patients with preoperative radiculopathy were without symptoms. Furthermore, 11 % of the patients reported severe neck stiffness, 5 % reported severe neck pain (Visual Analog Scale (VAS) ≥7), 6 % reported hoarseness, and 9 % reported dysphagia at the follow-up. The stable fusion rate, as evaluated using cervical-CT, was 98 %. Conclusions In this large consecutive series of patients with S-CS-fx treated with open surgical fixation, the surgical mortality was 2.3 %, the risk of neurological deterioration was 3.3 % and the reoperation rate (any cause) was 7.3 %. The neurological long-term results were good, with 51 % improvement in AIS grade and resolution of radiculopathy in 89 % of the patients. Stable fusion was excellent and was achieved in 98 % of the follow-up group.

Abstract
Study Design Retrospective case series. Purpose To clarify the influence of cervical spinal canal stenosis (CSCS) on neurological functional recovery after traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation. Overview of Literature The biomechanical etiology of traumatic CSCI remains under discussion and its relationship with CSCS is one of the most controversial issues in the clinical management of traumatic CSCI. Methods To obtain a relatively uniform background, patients non-surgically treated for an acute C3–4 level CSCI without major fracture or dislocation were selected. We analyzed 58 subjects with traumatic CSCI using T2-weighted mid-sagittal magnetic resonance imaging. The sagittal diameter of the cerebrospinal fluid (CSF) column, degree of canal stenosis, and neurologic outcomes in motor function, including improvement rate, were assessed. Results There were no significant relationships between sagittal diameter of the CSF column at the C3–4 segment and their American Spinal Injury Association motor scores at both admission and discharge. Moreover, no significant relationships were observed between the sagittal diameter of the CSF column at the C3–4 segment and their neurological recovery during the following period. Conclusions No relationships between pre-existing CSCS and neurological outcomes were evident after traumatic CSCI. These results suggest that decompression surgery might not be recommended for traumatic CSCI without major fracture or dislocation despite pre-existing CSCS.

Abstract
BACKGROUND Traumatic central cord syndrome (TCCS) is an incomplete spinal cord injury defined by greater weakness in upper versus lower extremities, variable sensory loss, and variable bladder, bowel, and sexual dysfunction. The optimal timing of surgery for TCCS remains controversial. OBJECTIVE To determine whether timing of surgery for TCCS predicts neurological outcomes, length of stay, and complications. METHODS Five databases were searched through March 2015. Articles were appraised independently by 2 reviewers, and the evidence synthesized according to Grading of Recommendation Assessment, Development and Evaluation principles. RESULTS Nine studies (3 prognostic, 5 therapeutic, 1 both) satisfied inclusion criteria. Low level evidence suggests that patients operated on <24 hours after injury exhibit significantly greater improvements in postoperative American Spinal Injury Association motor scores and the functional independence measure at 1 year than those operated on >24 hours after injury. Moderate evidence suggests that patients operated on <2 weeks after injury have a higher postoperative Japanese Orthopaedic Association score and recovery rate than those operated on >2 weeks after injury. There is insufficient evidence that lengths of hospital or intensive care unit stay differ between patients who undergo early versus delayed surgery. Furthermore, there is insufficient evidence that timing between injury and surgery predicts mortality rates or serious or minor adverse events. CONCLUSION Surgery for TCCS <24 hours after injury appears safe and effective. Although there is insufficient evidence to provide a clear recommendation for early surgery (<24 hours), it is preferable to operate during the first hospital admission and <2 weeks after injury.

Abstract
OBJECTIVE Current recommendations for traumatic spinal cord injury treatment recommend immediate transfer to a spinal injury unit (SIU) where available following patient stabilisation. Although transfer is dependent on a variety of factors, the largest review was unable to justify implementation of such units on the basis of insufficient and lack of quality data in favour of care at the SIU as opposed to non-SIU centres. Our study sought to investigate: are subspecialty spinal injury units (SIUs) able to provide superior care compared with traditional trauma/rehab units? Is the standard of care of acute spinal cord injured patients to be managed in SIU's? METHOD A literature search was conducted across five major databases using the key terms: "spinal cord injury" AND "Spinal Injury Unit" OR "spinal rehabilitation" OR "spinal injury centre" OR "specialist care" OR "care requirements." RESULTS After review of over 500 studies, only 9 met inclusion criteria, 3 of which were past reviews. There were no relevant RCT's obtained. Standardised roles of global SIU units are needed to deliver equitable and high quality care as current evidence demonstrates variable standards of care and service (mean LOS range: 16-174 days). There is low quality evidence supporting earlier admission into SIU units being associated with improved neurological outcome, complication rates and reduced LOS, despite variations in the definition of "early admission" across studies. CONCLUSIONS Our review demonstrates a lack of standardisation within SIU on a global scale, with significantly different outcomes reported across published studies. New and higher quality evidence directly comparing SIU to non-SIU based care is required. Earlier transfer (<24 h) to SIU following initial injury and stabilisation is advised.

Abstract
Spinal cord injury remains a challenging clinical entity with considerable socioeconomic impact on patients, their families, and the healthcare system. Advances in medical care and rehabilitation continue to improve, but treatment outcomes following tissue regeneration for spinal cord injury remain dismal. Therefore, attempts at mediating the secondary effects of spinal cord injury remain the mainstay of current treatment. Recent studies evaluating the timing of decompression suggest improved neurologic recovery with early surgical decompression and the maintenance of mean arterial pressures >85 mm Hg. With systemic and local treatments, including riluzole, minocycline, GM1 ganglioside, BA-210, and granulocyte-colony stimulating factor, remaining in their infancy, randomized controlled trials demonstrating efficacy are needed before adopting their widespread use.

Abstract
OBJECT
The purpose of this study was to characterize changes in American Spinal Injury Association motor score (AMS) in the 1st week after traumatic central cord syndrome (CCS) to identify predictors of improved early outcome in patients treated with early versus delayed surgical intervention.
METHODS
All patients presenting to a regional spinal cord injury center between January 2004 and June 2009 were queried for those with a diagnosis of CCS. Patients treated conservatively were excluded. A prospectively maintained spinal cord injury database was used to track AMS throughout each patient’s hospitalization. Hospital records provided information regarding demographics, presenting neurological examination, imaging findings, comorbidities, timing and nature of surgical procedures, and length of stay (LOS) in the hospital and intensive care unit (ICU). Patients were separated into those who underwent early surgery, within 1 day of presentation (early group), and those who underwent surgery on a delayed basis (delayed group). Differences between groups were analyzed using the Student t-test and chi-square test. Predictors of outcome were identified using correlation analysis and multiple linear regression.
RESULTS
Of 426 patients in the database, 80 (18.8%) were diagnosed as having CCS, and 68 of them ultimately underwent surgical decompression. Nineteen (28%) of 68 patients underwent surgery within 1 day of presentation (early group) while the remaining 49 patients (72%) underwent surgery on a delayed basis (delayed group). The mean age in the early group was significantly younger than that of the delayed group (52 vs 59 years, p = 0.049). Other characteristics were similar between groups including sex, proportion of patients with cord edema on MRI (44% early vs 55% delayed, p = 0.47), and proportion of patients with cervical fracture (26% early vs 28% delayed, p = 0.98). Patients in the early group presented with an AMS of 62.5 versus 70.0 for the delayed group (p = 0.36). No difference in the change in AMS was seen at 7 days between the early group (-2.9 points) and the delayed group (-4.2 points) (p = 0.34). Additionally, the number of patients who had early improvement was similar between the early and delayed groups (50% vs 48%, respectively, p = 0.94). Neither time in the ICU (3.4 vs 3.4 days, p = 0.84) nor the overall LOS (10.5 vs 12.5 days, p = 0.59) was different in the early versus delayed groups, respectively. Correlation analysis and multiple linear regression demonstrated early surgery was not associated with change in AMS or AMS at Day 7. Age was identified as the only significant predictor of change in AMS and had a negative effect (coefficient = -0.34, p = 0.025).
CONCLUSIONS
Early treatment of patients with CCS remains controversial. Although some long-term neurological recovery is expected in patients with a CCS, surgeons and patients should not expect early neurological improvement with or without early operative intervention.

Abstract
Objective and Background: The objective of this study is to evaluate how the neurological outcome in patients operated for cervical spinal cord injury (SCI) is influenced by surgical timing, admission American Spinal Injury Association (ASIA) grading system, and age. Materials and Methods: From January 2004 to December 2011, we operated 110 patients with cervical SCI. Fifty-seven of them (44 males and 13 females) with preoperative neurological deficit, were included in this study with a complete follow-up. Age, sex, associated comorbidities (evaluated with Charlson comorbidity index [CCI]), mechanism of trauma, preoperative and follow-up ASIA score, time elapsed from injury to surgical treatment, preoperative cervical computed tomography scan or magnetic resonance imaging, type of fractures, and surgical procedure were evaluated for each patient. The patient population was divided into two groups related to the timing of surgery: Ultra-early surgery group (within 12 h from the trauma, 27 patients) and early surgery (within 12–72 h from the trauma, 30 patients). Statistical Analysis Used: The univariate analysis of data was carried out by the Chi-square test for discrete variables, the t-test for the continuous ones. Logistic regression was used for the multivariate analysis. Results: Neurological outcome was statistically better in ultra-early surgery group (<12 h) than in patient underwent surgery within 12–72 h (82.14% vs. 31%, multivariate analysis P = 0.005). The neurological improvement was also correlated with the age and the ASIA grade at admission in the univariate analysis (P = 0.006 and P = 0.017 respectively) and in the multivariate 1 (P = 0.037 and P = 0.006 respectively) while the CCI was correlated with the improvement only in the univariate analysis (P = 0.007). Conclusion: Nowadays, in patients with cervical SCI early surgery could be associated with improved outcome, most in case of young people with mild neurological impairment.

Abstract
Aims: This study was done with the aim to compare the clinical outcome and patients’ quality of life between early versus delayed surgically treated patients of acute subaxial cervical spinal cord injury. The current study was based on the hypothesis that early surgical decompression and fixations in acute subaxial cervical spinal cord trauma is safe and is associated with improved outcome as compared to delayed surgical decompression. Materials and Methods: A total of 69 patients were recruited and divided into early decompression surgery Group A (operated within 48 h of trauma; n = 23) and late/delayed decompression surgery Group B (operated between 48 h and 7 days of trauma; n = 46). The patients in both groups were followed up, and comparative differences noted in the neurological outcome, quality of life, and bony fusion. Results: The early surgery group spent lesser days in the intensive care unit and hospital (Group A 28.6 vs. Group B 35 days) had lesser postoperative complications (Group A 43% vs. Group B 61%) and a reduced mortality (Group A 30% vs. Group B 45%). In Group A, 38% patients had 1 American Spinal Injury Association (ASIA) grade improvement while 31% experienced >2 ASIA grade improvement. In Group B, the neurological improvement was 27% and 32%, respectively (P = 0.7). There was a significant improvement in the postoperative quality of life scores in both groups. Conclusion: Early surgery in patients with acute subaxial cervical spine injury should be considered strongly in view of the lesser complications, early discharge, and reduced mortality.

Abstract
BACKGROUND Type C3 thoracic fracture is a severe spinal injury, but one that is clinically rare, and there are few reports pertaining to the treatment of this type of fracture. No consensus has been achieved on the proper timing of spine fracture fixation; therefore, we focused on evaluating the surgical effects using a posterior approach and determining the influence of surgical timing on surgical outcomes. METHODS This was a retrospective cohort study of 36 cases of type C3 thoracic fracture in patients admitted to the hospital from April 2005 to October 2012, and who were divided into two groups according to the timing of surgery: early fixation (<72 h) and late fixation (>72 h). Surgical outcomes were analyzed based on surgery duration, intraoperative blood loss, intensive care unit and hospital stay, mortality rate, and complications. RESULTS There were 13 patients in the early fixation group and 23 patients in the late fixation group. Patients were treated with posterior decompression, intervertebral titanium mesh support, pedicle screw fixation, and fusion. All fractures involved a single segment: T7/T8 (8 patients), T9/T10 (11 patients), and T11/T12 (17 patients). All injuries were classified as American Spinal Injury Association (ASIA) grade A. Patients underwent periodic follow-up over a period of 12-30 months (average, 22.5 months). One patient developed ascending myelitis and died of respiratory failure 1 month after early fixation, and two patients died of pulmonary infection after late fixation procedures. Other patients achieved bone fusion without improvement in ASIA grade. No statistically significant difference in parameters was observed between groups. CONCLUSIONS Though type C3 thoracic fracture is one of the most severe spinal injuries, complete reduction and recovery of spinal stability can be achieved using a posterior approach. As clinical outcomes in this study were similar between early and late fixation procedures, early surgical intervention may not be helpful for improving neurologic recovery in type C3 thoracic fractures.

Abstract
STUDY DESIGN A retrospective study of surgically treated patients with cervical spinal cord injury (SCI) from the National Trauma Data Bank Research Data Set. OBJECTIVE To determine how time to surgery differs between SCI subtypes, where delays before surgery occur, and what factors are associated with delays. SUMMARY OF BACKGROUND DATA Studies have shown that patients with cervical SCI undergoing surgery within 24 hours after injury have superior neurological outcomes to patients undergoing later surgery, with most evidence coming from the incomplete SCI subpopulation. METHODS Surgically treated patients with cervical SCI from 2011 and 2012 were identified in National Trauma Data Bank Research Data Set and divided into subpopulations of complete, central, and other incomplete SCIs. Relationships between surgical timing and patient and injury characteristics were analyzed using multivariate regression. RESULTS A total of 2636 patients with cervical SCI were identified: 803 with complete SCI, 950 with incomplete SCI, and 883 with central SCI. The average time to surgery was 51.1 hours for patients with complete SCI, 55.3 hours for patients with incomplete SCI, and 83.1 hours for patients with central SCI. Only 44% of patients with SCI underwent surgery within the first 24 hours after injury, including only 49% of patients with incomplete SCI.The vast majority of time between injury and surgery was after admission, rather than in the emergency department or in the field. Upper cervical SCIs and greater Charlson Comorbidity Index were associated with later surgery in all 3 SCI subpopulations. CONCLUSION The majority of patients with SCI do not undergo surgery within the first 24 hours after injury, and the majority of delays occur after inpatient admission. Factors associated with these delays highlight areas of focus for expediting care in these patient populations. LEVEL OF EVIDENCE 4.

Abstract
In general, spinal cord injury without radiological abnormality (SCIWORA) with spondylosis is considered to be a central cord injury. This article describes the clinical features and surgical outcomes of atypical central cord injury in patients with spondylotic SCIWORA (ACCISS). Fifty-two patients were enrolled in the study from January 2006 to December 2011. Diagnoses were made from imaging (computed tomography, magnetic resonance imaging) and clinical findings. The neurologic status of patients was assessed using the American Spinal Injury Association (ASIA) score and Japanese Orthopaedic Association (JOA) score. Patients were divided into 3 groups with regard to the timing of surgery after injury: those undergoing early surgery (less than 24 hours after injury), those undergoing late surgery (more than 24 hours after injury but during initial admission to the hospital and within 3 weeks from injury), and those undergoing delayed surgery (during second admission to the hospital, within 3 months but later than 3 weeks from injury). Seventeen patients underwent early surgery, 22 underwent late surgery, and 13 underwent delayed surgery. Mean follow-up was 15 months (range, 5-33 months). Patients in all groups showed very good recovery after surgical treatment, with the recovery rate of ASIA and JOA scores being 68.6% and 60.2%, respectively. No significant difference in recovery rate was found between the groups with regard to the timing of surgery. This retrospective study supports the notion that surgical decompression is effective in the treatment of patients with ACCISS. Timing of surgery (less than 3 months) was not significantly associated with neurologic recovery.

Abstract
A prospective study was performed to evaluate the impact of surgical decompression (SD) and instrumented fusion within 8 h versus 8-24 h after injury on neurological recovery after cervical traumatic spinal cord injury (tSCI) in patients operated on in the UMC Ljubljana, Slovenia. Only patients with the American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades of A through C and with MRI-confirmed spinal cord compression were enrolled. The primary outcome was the change in AIS grade at the 6-month follow-up. Of the 48 enrolled patients, 22 patients who underwent surgery within 8 h (group 8 h) and 20 patients who underwent surgery between 8 and 24 h (Group 8-24 h) after injury concluded the study. At admission, there was no statistically significant difference in AIS grade between the study groups. At the 6-month follow-up, an improvement of at least two AIS grades was found in 45.5% of patients in group 8 h and in 10% of patients in group 8-24 h (p=0.017). The median improvement in the ASIA motor score was 38.5 (10.0-61.0) motor points in group 8 h and 15.0 (8.8-34.0) motor points in group 8-24 h (p=0.0468). In a multivariate analysis, adjusted for the preoperative AIS grade and the degree of spinal canal compromise, the odds of an at least two-grade AIS improvement were at least 106% higher for patients in group 8 h than for patients in group 8-24 h (odds ratio=11.08, p=0.004). No statistically significant difference was found in the rate of perioperative complications, pneumonia, and the number of ventilator-dependent days or the mortality between the groups. Our results suggest that the patients with tSCI who undergo SD within 8 h after injury have superior neurological outcomes than patients who undergo SD 8-24 h after injury, without any increase in the rate of adverse effects.

Abstract
STUDY DESIGN A retrospective study of surgically treated patients with acute traumatic central cord syndrome (ATCCS) from the National Trauma Data Bank Research Data Set. OBJECTIVE To determine the association of time to surgery, pre-existing comorbidities, and injury severity on mortality and adverse events in surgically treated patients with ATCCS. SUMMARY OF BACKGROUND DATA Although earlier surgery has been shown to be beneficial for other spinal cord injuries, the literature is mixed regarding the appropriate timing of surgery after ATCCS. Traditionally, this older population has been treated with delayed surgery because medical optimization is often indicated preoperatively. METHODS Surgically treated patients with ATCCS in the National Trauma Data Bank Research Data Set from 2011 and 2012 were identified. Time to surgery, Charlson Comorbidity Index, and injury severity scores were tested for association with mortality, serious adverse events, and minor adverse events using multivariate logistic regression. RESULTS A total of 1060 patients with ATCCS met inclusion criteria. After controlling for pre-existing comorbidity and injury severity, delayed surgery was associated with a decreased odds of inpatient mortality (odds ratio = 0.81, P = 0.04), or a 19% decrease in odds of mortality with each 24-hour increase in time until surgery. The association of time to surgery with serious adverse events was not statistically significant (P = 0.09), whereas time to surgery was associated with increased odds of minor adverse events (odds ratio = 1.06, P < 0.001). CONCLUSION Although the potential neurological effect of surgical timing for patients with ATCCS remains controversial, the decreased mortality with delayed surgery suggests that waiting to optimize general health and potentially allow for some spinal cord recovery in these patients may be advantageous.

Abstract
BACKGROUND In France, attempts to define common ground during spine surgery meetings have revealed significant variability in clinical practices across different schools of surgery and the two specialities involved in spine surgery, namely, neurosurgery and orthopaedic surgery. OBJECTIVES To objectively characterise this variability by performing a survey based on a fictitious spine trauma case. Our working hypothesis was that significant variability existed in trauma practices and that this variability was related to a lack of strong scientific evidence in spine trauma care. METHODS We performed a cross-sectional survey based on a clinical vignette describing a 31-year-old male with an L1 burst fracture and neurologic symptoms (numbness). Surgeons received the vignette and a 14-item questionnaire on the management of this patient. For each question, surgeons had to choose among five possible answers. Differences in answers across surgeons were assessed using the Index of Qualitative Variability (IQV), in which 0 indicates no variability and 1 maximal variability. Surgeons also received a questionnaire about their demographics and surgical experience. RESULTS Of 405 invited spine surgeons, 200 responded to the survey. Five questions had an IQV greater than 0.9, seven an IQV between 0.5 and 0.9, and two an IQV lower than 0.5. Variability was greatest about the need for MRI (IQV=0.93), degree of urgency (IQV=0.93), need for fusion (IQV=0.92), need for post-operative bracing (IQV=0.91), and routine removal of instrumentation (IQV=0.94). Variability was lowest for questions about the need for surgery (IQV=0.42) and use of the posterior approach (IQV=0.36). Answers were influenced by surgeon specialty, age, experience level, and type of centre. CONCLUSION Clinical practice regarding spine trauma varies widely in France. Little published evidence is available on which to base recommendations that would diminish this variability.

Abstract
Thoracolumbar spine fractures are common injuries that can result in significant disability, deformity and neurological deficit. Controversies exist regarding the appropriate radiological investigations, the indications for surgical management and the timing, approach and type of surgery. This review provides an overview of the epidemiology, biomechanical principles, radiological and clinical evaluation, classification and management principles. Literature review of all relevant articles published in PubMed covering thoracolumbar spine fractures with or without neurologic deficit was performed. The search terms used were thoracolumbar, thoracic, lumbar, fracture, trauma and management. All relevant articles and abstracts covering thoracolumbar spine fractures with and without neurologic deficit were reviewed. Biomechanically the thoracolumbar spine is predisposed to a higher incidence of spinal injuries. Computed tomography provides adequate bony detail for assessing spinal stability while magnetic resonance imaging shows injuries to soft tissues (posterior ligamentous complex [PLC]) and neurological structures. Different classification systems exist and the most recent is the AO spine knowledge forum classification of thoracolumbar trauma. Treatment includes both nonoperative and operative methods and selected based on the degree of bony injury, neurological involvement, presence of associated injuries and the integrity of the PLC. Significant advances in imaging have helped in the better understanding of thoracolumbar fractures, including information on canal morphology and injury to soft tissue structures. The ideal classification that is simple, comprehensive and guides management is still elusive. Involvement of three columns, progressive neurological deficit, significant kyphosis and canal compromise with neurological deficit are accepted indications for surgical stabilization through anterior, posterior or combined approaches.

Abstract
A traumatic spinal cord injury is a catastrophic event associated with physiologic disruptions to the motor, sensory, cardiovascular, and respiratory systems. Respiratory complications are a common cause of morbidity and mortality in patients with acute cervical spinal cord injury and treatments must be initiated immediately. The longer it takes for a patient to receive pulmonary treatments and mobility activities, the higher the morbidity and mortality and the longer the length of stay. Disrupted pulmonary mechanics and respiratory complications are frequent and are influenced by the level of injury.

Abstract
Study Design Prospective observational study. Purpose To assess the clinical outcome after early versus late decompression for traumatic cervical cord injury. Overview of Literature Traumatic spinal cord injury is common globally with the most tragic outcomes in the cervical spine. Although recent studies have shown that early decompression results in more favourable outcome, its authority is yet to be established. Methods Study on 98 patients with a traumatic cervical cord injury was conducted over a period of 5 years. The patients who were operated on within 24 hours of the onset of the primary injury (n=34) were classified as the early group, and those who were operated on after 24 hours of the onset of the injury (n=64) were categorized as the late group. The outcome of both the groups was assessed using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) at the 6-month follow-up. Results The patients in the early group were operated on at a mean time of 18.4 hours (range, 13-24 hours) while patients were operated on at a mean time of 52.7 hours (range, 31-124 hours) in the late group. At the 6-month follow-up, 7 (23.3%) in the early group and 5 (8.7%) in the late group showed >2 grade improvement in the AIS. Conclusions The results of patients undergoing decompression within 24 hours of the injury are better than those who are operated on later. An attempt should be made to decompress the traumatic cervical spine early in all possible cases.

Abstract
STUDY DESIGN Retrospective case-control study. OBJECTIVE The objective of the study was to compare neurological outcomes and complication rates between a series of combat-injured patients treated in Afghanistan (AFG) and those treated at Landstuhl Regional Medical Center (LRMC). SUMMARY OF BACKGROUND DATA At present, no studies have addressed the ideal timing and setting for surgical stabilization in combat-injured soldiers who sustain spinal trauma. METHODS Soldiers who sustained spine injuries while deployed to Afghanistan and who underwent surgery in theater or at LRMC between 2010 and 2011 were identified. Demographic information, injury-specific data, neurological status, type of surgical intervention, postoperative complications, and need for additional surgery were abstracted for all patients. Neurological improvement was the primary dependent variable. Secondary variables included the risk of developing complications and the need for additional surgery. Statistical analysis was performed using t tests, and the Fisher exact test was used for categorical variables. RESULTS Between 2010 and 2011, 30 individuals were treated in AFG, and 20 received surgery at LRMC. Neurological improvement occurred in 10% of AFG patients and 5% of those treated at LRMC. Complications occurred in 40% of AFG patients and in 20% of the LRMC group. Twenty-three percent of AFG patients required additional spine surgery after leaving Afghanistan. There was no statistical difference in neurological improvement between the AFG and LRMC groups (P=0.64). Soldiers who received surgery in AFG were at significantly increased risk of requiring additional procedures (P=0.03). CONCLUSIONS Soldiers treated in theater did not have statistically higher rates of neurological improvement as compared with those treated at LRMC. Patients treated in-theater were at elevated risk for the need for additional surgery. This study is among the first to evaluate clinical outcomes after surgical intervention for war-related spinal trauma. LEVEL OF EVIDENCE Level III (case-control).

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To evaluate the influence of static compression factors and dynamic factors based on the various degrees of traumatic force on the cervical spinal cord injury (SCI) in patients with ossification of the posterior longitudinal ligament. SUMMARY OF BACKGROUND DATA Spinal cord disorder occurs as a result of various factors, including static factors and traumatic force. Discussions about the severity of paralysis resulting from SCI must therefore focus on dynamic factors based on the traumatic force as well as on static compression factors. However, the past reports did not describe the influence of traumatic force in detail. METHODS Fifty patients presenting with cervical SCI associated with ossification of the posterior longitudinal ligament were included in this study. The American Spinal Injury Association motor score 3 days after injury, the degree of the traumatic force, and the spinal cord compression rate were investigated, and the relationships among these factors were investigated. RESULTS Paralysis at the time of injury was not determined by static factors alone or by traumatic force alone. The severity of paralysis at the time of injury was determined on the basis of a combination of both the static factors and the degree of traumatic force. CONCLUSION Both the degree of spinal cord compression and the degree of traumatic force were found to be important factors associated with the severity of cervical SCI in patients with ossification of the posterior longitudinal ligament.

Abstract
Numerous studies in animals have shown the unique property of olfactory ensheathing cells to stimulate regeneration of lesioned axons in the spinal cord. In a Phase I clinical trial, we assessed the safety and feasibility of transplantation of autologous mucosal olfactory ensheathing cells and olfactory nerve fibroblasts in patients with complete spinal cord injury. Six patients with chronic thoracic paraplegia (American Spinal Injury Association class A-ASIA A) were enrolled for the study. Three patients were operated, and three served as a control group. The trial protocol consisted of pre- and postoperative neurorehabilitation, olfactory mucosal biopsy, culture of olfactory ensheathing cells, and intraspinal cell grafting. Patient's clinical state was evaluated by clinical, neurophysiological, and radiological tests. There were no adverse findings related to olfactory mucosa biopsy or transplantation of olfactory ensheathing cells at 1 year after surgery. There was no evidence of neurological deterioration, neuropathic pain, neuroinfection, or tumorigenesis. In one cell-grafted patient, an asymptomatic syringomyelia was observed. Neurological improvement was observed only in transplant recipients. The first two operated patients improved from ASIA A to ASIA C and ASIA B. Diffusion tensor imaging showed restitution of continuity of some white matter tracts throughout the focus of spinal cord injury in these patients. The third operated patient, although remaining ASIA A, showed improved motor and sensory function of the first spinal cords segments below the level of injury. Neurophysiological examinations showed improvement in spinal cord transmission and activity of lower extremity muscles in surgically treated patients but not in patients receiving only neurorehabilitation. Observations at 1 year indicate that the obtaining, culture, and intraspinal transplantation of autologous olfactory ensheathing cells were safe and feasible. The significance of the neurological improvement in the transplant recipients and the extent to which the cell transplants contributed to it will require larger numbers of patients.

Abstract
The recovery of walking function is considered of extreme relevance both by patients and physicians. Consequently, in the recent years, recovery of locomotion become a major objective of new pharmacological and rehabilitative interventions. In the last decade, several pharmacological treatment and rehabilitative approaches have been initiated to enhance locomotion capacity of SCI patients. Basic science advances in regeneration of the central nervous system hold promise of further neurological and functional recovery to be studied in clinical trials. Therefore, a precise knowledge of the natural course of walking recovery after SCI and of the factors affecting the prognosis for recovery has become mandatory. In the present work we reviewed the prognostic factors for walking recovery, with particular attention paid to the clinical ones (neurological examination at admission, age, etiology gender, time course of recovery). The prognostic value of some instrumental examinations has also been reviewed. Based on these factors we suggest that a reliable prognosis for walking recovery is possible. Instrumental examinations, in particular evoked potentials could be useful to improve the prognosis.

Abstract
We present a case of traumatic espondylolisthesis L5 S1 A0 53 B3.3 ASIA B in a young patient after a high energy car accident. This entity is a rare injury that requires immediate attention. Treatment should be prompt in order to provide the best prognosis since this is an unstable and severe lesion that presents with neurological deficit in half of the patients. Computed tomography and magnetic resonance imaging have shown to be extremely valuable for the diagnosis and are mandatory for this kind of injuries. In this case it is noteworthy that the intervertebral disk was intact. It is reported that if surgery is performed 24 to 48 hours after the accident, the improvement of neurological deficit is very feasible. In this case posterolateral fusion with autologous bone graft and multiplanar transpedicular posterior instrumentation and decompression were performed 52 hours after the accident. The patient presents one year after surgery with improvement in movement and sphincter control and with radiographic evidence of a complete fusion.

Abstract
OBJECTIVE: The objective was to assess the improvement of chronic low back pain in osteoporotic patients treated with teriparatide (TPTD). METHODS: This was an observational study with a convenience sample of 21 patients with osteoporosis using TPTD, 20 mcg/day, between 2006 and 2010, with chronic low back pain (more than three months). Dorsolumbar radiographs and bone densitometry (DXA) were performed before and after treatment. For pain measurement the VAS pain scale was used. Data were entered in Excel and processed in STATA/SE 8.0 with Chi2 square or Fisher (p < 0.05). RESULTS: twenty-one patients aged 40-90 (mean 70 years), eight (40%) had senile osteoporosis and thirteen (60%) had osteoporosis secondary to medications. Seventeen (80%) had previous dorsolumbar fractures. Ten (47.5%) used TPTD for 24 months, six (27.5 %) used the medication for 18 months, four (20%) for 12 months and one (5%) for six months. Eight patients (40%) received previous anti-reabsortive therapy. Thirteen patients (60%) exhibited bone mass gain between 0% and 9% while eight (40%), between 10% and 15%. The final average VAS was 2.6 representing an improvement of 4.7 (p< 0.05). CONCLUSION: There was a significant reduction in the severity of low back pain with the use of TPTD (initial mean VAS: 7.3, final VAS: 2.6, improvement: 4.7).

Spatial and temporal expression levels of specific microRNAs in a spinal cord injury mouse model and their relationship to the duration of compression. Spine J 2014; 14:353-60. [PMID: 24269082 DOI: 10.1016/j.spinee.2013.08.015] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2012] [Revised: 07/16/2013] [Accepted: 08/21/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT MicroRNAs, a class of small nonprotein-coding RNAs, are thought to control gene translation into proteins. The latter are the ultimate effectors of the biochemical cascade occurring in any physiological and pathological process. MicroRNAs have been shown to change their expression levels during injury of spinal cord in contusion rodent models. Compression is the most frequent mode of damage of neural elements in spinal cord injury. The cellular and molecular changes occurring in the spinal cord during prolonged compression are not very well elucidated. Understanding the underlying molecular events that occur during sustained compression is paramount in building new therapeutic strategies. PURPOSE The purpose of our study was to probe the relationship between the expression level changes of different miRNAs and the timing of spinal cord decompression in a mouse model. STUDY DESIGN A compression spinal cord injury mouse model was used for the study. METHODS A laminectomy was performed in the thoracic spine of C57BL/6 mice. Then, the thecal sac was compressed to create the injury. Decompression was performed early for one group and it was delayed in the second group. The spinal cord at the epicenter of the injury and one level rostral to it were removed at 3, 6, and 24 hours after trauma, and RNA was extracted. Expression levels of six different microRNAs and the relationship to the duration of compression were analyzed. This work was supported in part by the University Research Council Grants Program at the University of Texas Health Science Center San Antonio (Grant 130267). There are no specific conflicts of interest to be disclosed for this work. RESULTS Expression levels of microRNAs in the prolonged compression of spinal cord model were significantly different compared with the expression levels in the short duration of compression spinal cord injury model. Furthermore, microRNAs show a different expression pattern in different regions of the injured spinal cord. CONCLUSIONS Our findings demonstrate that spinal cord compression causes alterations in the expression of different miRNAs in the acute phase of injury. Their expression is related to the duration of the compression of the spinal cord. These findings suggest that early decompression of the spinal cord may have an important modulating effect on the molecular cascade triggered during secondary injury through the changes in expression levels of specific microRNAs.

Abstract
Complete traumatic fracture-dislocation of the lumbar spine is a rare spinal injury often leading to death. Surgical intervention is an effective treatment modality to decrease mortality. Our patient was a 16 year old boy who had a collision caused by fall from a construction material lifter. He was referred to our hospital with waist trauma. Later, the patient underwent posterior surgical decompression during which vertebral column restoration by long segment fixation was performed. After surgery there were no significant changes in the patient condition.

Abstract
OBJETIVOS: Analizar cinemática, reconocer cuadro clínico de presentación, describir imágenes, considerar posibilidades terapéuticas y evaluar evolución. MÉTODO: Se analizan 13 pacientes del sexo masculino que presentaron SCIWORA (en inglés Spinal cord injury without radiographic abnormality) entre el 2005 al 2012. Se evalúan cuadro clínico, tratamiento, complicaciones y evolución. RESULTADOS: 10 pacientes mayores de 45 años presentaban signos de espondiloartrosis con mínimos síntomas. De los tres menores de esta edad solo uno presentaba estenosis de canal constitucional asintomática. Todos sufrieron trauma de baja energía. En la resonancia magnética prevaleció el hematoma intramedular y clínicamente todos los pacientes presentaban un síndrome medular central, con cuadro severo (ASIA A-B) en los mayores de 45 años. Siete pacientes fueron tratados inicialmente en forma conservadora; un paciente empeoró y tuvo que ser sometido a intervención quirúrgica 18 meses después y otro falleció en las primeras horas, el resto de los pacientes tuvieron buena evolución. Seis pacientes requirieron cirugía (laminoplastía) en los primeros 10 días; tres fallecieron y el resto mejoro por lo menos un nivel ASIA. CONCLUSIONES: La menor edad, los cuadros leves y el edema intramedular son factores de buen pronóstico y se ven favorecidos con el tratamiento conservador. La mayor edad, la espondiloartrosis y los cuadros severos o progresivos, son factores de mal pronóstico y puede ser necesario su tratamiento quirúrgico.
