RESUMO

INTRODUCTION: Central cord syndrome, the most common incomplete traumatic spinal cord injury, often results in functional impairment with variable recovery. CASE PRESENTATION: Central cord syndrome developed in a 64-year-old man during routine home use of an inversion table. DISCUSSION: The incidence of central cord syndrome, which occurs most frequently after a fall, is increasing among older persons. Age-related changes in the cervical spine may predispose the spinal cord to compression and injury during a fall. Evidence for lumbar traction as treatment of low back pain is limited. CONCLUSIONS: This unusual case of spinal cord injury during inversion table use highlights the relationship between anatomical changes in the cervical spine and the mechanism of injury typical in central cord syndrome. The resulting increased risk of central cord syndrome for older adults should be discussed with patients in the context of activities that could lead to falls or cervical spine extension.

RESUMO

OBJECTIVES: To analyze the prognostic and risk factors related to surgical treatment of central spinal cord syndrome (CSS) and to find out the optimal timing of operative management. METHODS: From January 2011 to January 2019, a consecutive series of 128 patients with CSS confirmed by magnetic resonance imaging (MRI) were retrospectively analyzed including their clinical records and radiologic data from a prospectively maintained database in a single center. RESULTS: According to the prognosis evaluated by the modified Japanese Orthopedic Association (mJOA), American Spinal Injury Association (ASIA) motor score (AMS), and ASIA impairment scale (AIS) grade, the overall postoperative outcome was good. Finally, it was found that surgical timing, presence of myelopathy or not at baseline, AMS at admission, and compression ratio were independent factors affecting the prognosis. Surgery as soon as possible after the occurrence of CSS is still advocated. CONCLUSION: Cervical myelopathy at baseline, compression ratio, and AMS score on admission were independent prognostic factors for the surgical treatment of CSS. If surgical indications are clear, early surgical intervention should be actively considered.

RESUMO

BACKGROUND: Charcot neuroarthropathy (CNA) of the upper extremity occurs most frequently in shoulders. However, CNA in the hands is uncommon and seldom be reported. The onset of CNA is usually insidious. If this process continues undetected, it can result in joint deformity, ulceration and/or superinfection, loss of function, and amputation or even death. In this article, we are going to present three cases of CNA in the hands of individuals with cervical spinal cord injury (SCI) with central cord syndrome. CASE PRESENTATION: Three male individuals with cervical spinal stenosis contracted tetraplegia (American Spinal Injury Association Impairment Scale Grade D, D, and B) due to spinal cord contusion after a trauma and developed hand swelling without pain 2 to 3 months after their SCI. X-ray showed degenerative joint changes in the hands. CNA was considered due to the patient's history of cervical SCI, loss of motor function and sensation, symptoms of painless swelling, physical examination, and X-ray findings. The self-care sub scores of Spinal Cord Independence Measure III improved slightly only during rehabilitation and follow-up due to poor hand function. CONCLUSIONS: CNA may develop after a central or peripheral neurological disorder. Nearly every joint of the body can be affected and the lower limbs are the most frequently involved. However, CNA of the hand is rare. We present three patients with CNA in the hands after cervical SCI and review the features and early differential diagnosis of CNA. Currently there is no specific treatment available. Therefore, early identification of CNA and adequate protection to the affected joints seem important.

RESUMO

OBJECTIVE: To explore the sagittal radiological parameters related to clinical recovery of patients with acute traumatic central cord syndrome (ATCCS) and determine the diagnostic value of related variables. METHODS: A retrospective review was performed of 104 patients with ATCCS. Six cervical sagittal balance parameters were collected: Cobb angle, T1 slope, neck tilt, thoracic inlet angle (TIA), C2-C7 sagittal vertex axis, T1 slope - C2-C7 Cobb angle. The patients were assigned to an ideal improvement group and poor improvement group according to their recovery rate. Receiver operating characteristic curve and area under the curve were used to evaluate the significant results of logistic regression and the optimal diagnostic value. RESULTS: Preoperative and postoperative Japanese Orthopaedic Association scores indicated a good recovery after surgical intervention. Radiological findings revealed that neck tilt and TIA were risk factors for poor neurological improvement of patients with ATCCS. Area under the curve (95% confidence interval) values of neck tilt and TIA were 0.763 (0.660-0.866) and 0.749 (0.643-0.855), and cutoff values were 39.1° and 65.6°, respectively. CONCLUSIONS: Lower neck tilt and TIA are risk factors for poor outcomes in patients with ATCCS after surgery. Neck tilt <39° and TIA <66° had significant diagnostic value for poor prognosis.

RESUMO

STUDY DESIGN: A retrospective cohort study. OBJECTIVE: This study aims to determine whether quantitative magnetic resonance imaging (MRI) parameters and radiological scoring systems could be used as a reliable assessment tool for predicting neurological recovery trajectory following acute traumatic central cord injury syndrome (CCS). SUMMARY OF BACKGROUND DATA: Controversy remains in whether CCS should be managed conservatively or by early surgical decompression. It is essential to understand how clinical and radiological parameters correlate with neurological deficits and how they predict recovery trajectories. METHODS: We identified patients with CCS admitted between 2011 and 2018 with a minimum of 1-year follow-up. Cervical MRIs were analyzed for cord/canal dimensions, Brain and Spinal Injury Center (BASIC) scores and sagittal grading as ordinal scales of intraparenchymal cord injury. Japanese Orthopaedic Association (JOA) recovery rates (≥50% as good, < 50% as poor) were analyzed against these variables by logistic regression and receiver operator characteristic (ROC) curves. Additionally, we evaluated American Spinal Injury Association motor scale (AMS) scores/recovery rates. RESULTS: Sixty patients were included, of which 30 were managed conservatively and 30 via surgical decompression. The average follow-up duration for the entire cohort was (51.1 ±â€Š25.7) months. Upon admission, sagittal grading correlated with AMS and JOA scores (P < 0.01, ß = 0.48). Volume of the C2 to C7 canal and axial cord area over the site of maximal compression correlated with AMS and JOA scores respectively (P = 0.04, ß = 0.26; P = 0.01, ß = 0.28). We determined admission AMS more than 61 to be a clinical cutoff for good recovery (area under the receiver operating curve [AUC] = 0.74, 95% confidence interval [CI]: 0.61-0.85, sensitivity 80.9%, specificity 69.2%, P < 0.01). Radiological cutoffs to identify patients with poor recovery rates were length of cervical spinal stenosis more than 3.9 cm (AUC = 0.76, 95% CI: 0.63-0.87, specificity 91.7%, sensitivity 52.2%, P < 0.01), BASIC score of more than 1 (AUC = 0.69, 95% CI: 0.56-0.81, specificity 80.5%, sensitivity 51.1%, P = 0.02). Surgical decompression performed as a salvage procedure upon plateau of recovery did not improve neurological outcomes. CONCLUSION: Clinical and radiological parameters upon presentation were prognosticative of neurological recovery rates in CCS. Surgery performed beyond the acute post-injury period failed to improve outcomes.Level of Evidence: 3.

RESUMO

The corticospinal tract (CST) is the preeminent voluntary motor pathway that controls human movements. Consequently, long-standing interest has focused on CST location and function in order to understand both loss and recovery of neurological function after incomplete cervical spinal cord injury, such as traumatic central cord syndrome. The hallmark clinical finding is paresis of the hands and upper-extremity function with retention of lower-extremity movements, which has been attributed to injury and the sparing of specific CST fibers. In contrast to historical concepts that proposed somatotopic (laminar) CST organization, the current narrative summarizes the accumulated evidence that 1) there is no somatotopic organization of the corticospinal tract within the spinal cord in humans and 2) the CST is critically important for hand function. The evidence includes data from 1) tract-tracing studies of the central nervous system and in vivo MRI studies of both humans and nonhuman primates, 2) selective ablative studies of the CST in primates, 3) evolutionary assessments of the CST in mammals, and 4) neuropathological examinations of patients after incomplete cervical spinal cord injury involving the CST and prominent arm and hand dysfunction. Acute traumatic central cord syndrome is characterized by prominent upper-extremity dysfunction, which has been falsely predicated on pinpoint injury to an assumed CST layer that specifically innervates the hand muscles. Given the evidence surveyed herein, the pathophysiological mechanism is most likely related to diffuse injury to the CST that plays a critically important role in hand function.

RESUMO

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.

RESUMO

Burning Hands Syndrome is an unusual variant of central cord syndrome. There have been few published reports, and none in the emergency medicine literature. We present a case of Burning Hands Syndrome in which there were no computed tomography (CT) findings of cervical spine injury and only subtle magnetic resonance (MR) abnormalities. We discuss the importance of early diagnosis, as the optimal management of these patients ultimately depends upon prompt recognition of the underlying cervical trauma and a spinal cord at risk for further injury.

RESUMO

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.

RESUMO

PURPOSE: To revisit the concept of spondylotic traumatic central cord syndrome (TCCS) by assessing the frequency of discoligamentous injury and to correlate magnetic resonance imaging (MRI) and intraoperative findings. METHODS: A retrospective analysis of twenty-three consecutive patients (mean age: 62.7 ± 14.8 years) with profound spondylotic TCCS after acute cervical hyperextension trauma but without signs of instability on initial CT scans who underwent anterior surgical decompression and fusion was performed. Sensitivity and specificity of MRI in the detection of anterior longitudinal ligament disruption were calculated. The topographic relations between surgically verified segmental instabilities and spinal cord signals on MRI were analyzed. The cervical MRI scans of all patients were evaluated by the radiologist on call at time of admission, re-assessed by a specialized MRI radiologist for the purpose of this study and compared with intraoperative findings. RESULTS: Intraoperative findings revealed 25 cervical spine segments with hyperextension instability in 22 of 23 (95.7%) patients. The radiologist on call correctly assessed segmental hyperextension instability in 15 of 25 segments (sensitivity: 0.60, specificity: 1.00), while the specialized MRI radiologist was correct in 22 segments (sensitivity: 0.88, specificity: 1.00). In 17 of 23 (73.9%) patients, the level of spinal cord signal on MRI matched the level of surgically verified segmental instability. CONCLUSIONS: Our findings challenge the traditional concept of spondylotic TCCS as an incomplete cervical spinal cord injury without discoligamentous injury and emphasize the importance of MRI as well as the radiologist's level of experience for the assessment of segmental instability in these patients.

RESUMO

Central cord syndrome (CCS) represents a clinical phenomenon characterized by disproportionately greater motor impairment of the upper than of the lower extremities, bladder dysfunction. CSS is the most common form of incomplete traumatic spinal cord injury. The initial description of CSS was reported in 1887 secondary to cervical spinal trauma. However, recent literature describes a heterogenous injury patterns including high-energy and low-energy mechanisms and bimodal patient age distributions. Pathophysiology of clinical symptoms and neurological deficits often is affected by preexisting cervical spondylosis. Urgent clinical diagnosis is dependent on neurological examination and imaging studies. Treatment of CSS is dependent on injury mechanism and compressive lesions, neurological examination, preexisting cervical pathology, and patient-specific comorbidities. This article will review the current concepts in diagnosis, pathophysiology, and treatment of CSS with a highlighted case example.

RESUMO

A 57-year-old male presented with recurrent falls, bilateral lower-limb paresthesia, and severe neck pain. Imaging revealed a mass compressing his spinal cord. He was admitted for further workup for spinal cord compression. Within 24 hours of admission, he developed upper-extremity weakness while maintaining lower-extremity function. He underwent urgent decompression of his spinal cord. During exposure, a white, creamy odorless substance was noted. This same substance was found under pressure within the spinal canal. The mass was grossly removed, and the patient's weakness improved postoperatively. Based on the clinical picture, intraoperative presentation, and final histological examination, idiopathic tumoral calcinosis-like lesion was considered as the most appropriate diagnosis.

RESUMO

IMPORTANCE: Current trauma guidelines dictate that the cervical spine should not be cleared in intoxicated patients, resulting in prolonged immobilization or additional imaging. Modern computed tomography (CT) technology may obviate this and allow for immediate clearance. OBJECTIVE: To analyze cervical spine clearance practices and the utility of CT scans of the cervical spine in intoxicated patients with blunt trauma. DESIGN, SETTING, AND PARTICIPANTS: We performed a prospective observational study of 1668 patients with blunt trauma aged 18 years and older who underwent cervical spine CT scans from March 2014 to March 2015 at an American College of Surgeons-verified Level I trauma center. Intoxication was determined by serum alcohol levels and urine drug screens. Physical examination and CT scan findings were evaluated for cervical spine injuries (CSI) and the incidence of missed injuries. MAIN OUTCOMES AND MEASURES: Clinically relevant CSIs requiring cervical stabilization. The hypotheses formed prior to data collection were that cervical CT scans are sensitive and specific enough to diagnose CSIs that require stabilization and that normal CT scans are sufficient to clear CSIs in intoxicated patients. RESULTS: Of 1668 patients, 1103 (66.1%) were male, with a mean (SD) age of 49 (20) years and a mean (SD) Injury Severity Score of 10 (9). Vehicular (734 [44.0%]) and falls (579 [34.7%]) were the most common mechanisms for hospitalization. Intoxication was identified in 632 of 1429 of patients tested (44.2%; 425 [29.7%] by serum alcohol levels and 350 [24.5%] by urine drug screens). Half (316 [50.0%]) were admitted with cervical spine immobilization, and 38 (12%) of these were solely owing to the presence of intoxication. There were 65 abnormal CT scans (10.3%) in the intoxicated group. Among 567 normal CT scans, 4 (0.7%) had central cord syndrome found on initial physical examination, and 1 (0.2%) had a symptomatic unstable ligament injury that was misread as normal on CT scan but was abnormal on magnetic resonance imaging. The 316 patients kept in a cervical collar for intoxication had no missed CSIs but were kept immobilized for a mean (SD) of 12 (19) hours. Computed tomographic scans had an overall negative predictive value of 99.2% for patients with CSIs and a negative predictive value of 99.8% for ruling out CSIs that required immobilization or stabilization. CONCLUSIONS AND RELEVANCE: In this study, alcohol or drug intoxication was common and resulted in significant delays to cervical spine clearance. Computed tomographic scans were highly reliable for identifying all clinically significant CSIs. Spine clearance based on a normal CT scan among intoxicated patients with no gross motor deficits appears to be safe and avoids prolonged and unnecessary immobilization.

RESUMO

Spinal cord injury (SCI) can be complete or incomplete. The level of injury in SCI is defined as the most caudal segment with motor function rated at greater than or equal to 3/5, with pain and temperature preserved. The standard neurological classification of SCI provided by the American Spinal Injury Association (ASIA) assigns grades from ASIA A (complete SCI) through ASIA E (normal sensory/motor), with B, C, and D representing varying degrees of injury between these extremes. The most common causes of SCI include trauma (motor vehicle accidents, sports, violence, falls), degenerative spinal disease, vascular injury (anterior spinal artery syndrome, epidural hematoma), tumor, infection (epidural abscess), and demyelinating processes ().

RESUMO

OBJECTIVE The aim of this paper was to compare the severity of the initial neurological injury as well as the early changes in the American Spinal Injury Association (ASIA) motor score (AMS) between central cord syndrome (CCS) patients with and without an increased T2 signal intensity in their spinal cord. METHODS Patients with CCS were identified and stratified based on the presence of increased T2 signal intensity in their spinal cord. The severity of the initial neurological injury and the progression of the neurological injury over the 1st week were measured according to the patient's AMS. The effect of age, sex, congenital stenosis, surgery within 24 hours, and surgery in the initial hospitalization on the change in AMS was determined using an analysis of variance. RESULTS Patients with increased signal intensity had a more severe initial neurological injury (AMS 57.6 vs 75.3, respectively, p = 0.01). However, the change in AMS over the 1st week was less severe in patients with an increase in T2 signal intensity (-0.85 vs -4.3, p = 0.07). Analysis of variance did not find that age, sex, Injury Severity Score, congenital stenosis, surgery within 24 hours, or surgery during the initial hospitalization affected the change in AMS. CONCLUSIONS The neurological injury is different between patients with and without an increased T2 signal intensity. Patients with an increased T2 signal intensity are likely to have a more severe initial neurological deficit but will have relatively minimal early neurological deterioration. Comparatively, patients without an increase in the T2 signal intensity will likely have a less severe initial injury but can expect to have a slight decline in neurological function in the 1st week.

RESUMO

Acute traumatic central cord syndrome is commonly associated with major trauma such as falling and motor vehicle crash, but minor or nontraumatic causes are very rare in children. As a consequence, most physicians frequently overlook children presenting with complaints of arm weakness when history of any definite major trauma does not exist, especially in the emergency department. We present the case of a 7-year-old boy who was experiencing weakness in both arms after a standing high jump with tilting his head back in school. He had no history of any definite trauma and no evidence of bone abnormalities on plain radiography and computed tomography of the cervical spine. Magnetic resonance imaging of the cervical spine revealed observable swelling with increased signal intensity at C1 to 4 levels. This case showed a spinal cord injury caused by standing high jump with neck extension alone. Therefore, the physicians have to consider the possibility of spinal cord injury even without any history of major trauma.

RESUMO

OBJECT: The authors undertook a study in patients with traumatic central cord syndrome (TCCS) who underwent surgical intervention. They retrospectively assessed the motor score improvement and functional status and identified prognostic predictors of improvement. METHODS: Between March 1999 and May 2004, 49 patients with TCCS were surgically treated. Motor scores were collected at admission and follow-up using the American Spinal Injury Association (ASIA) Impairment Scale. The 36-Item Short Form Health Survey (SF-36) was administered. Other parameters including walking index, spasticity, bladder management, and neuropathic pain scores were recorded. Patients were asked to assess their level of satisfaction with their final symptoms. RESULTS: The average ASIA score, converted into numeric values, was increased from 54.9 at admission to 81.9 and 89.6 at 6 months and final follow-up, respectively. Significant improvement of ASIA score was achieved within the first 6 months of surgery. No significant difference was found between patients who underwent surgery within 4 days of injury or after 4 days of injury, adopting different approaches (anterior, posterior, or a combination), or with different pathological entities (acute disc herniation, fracture or dislocation, or multilevel degeneration). The ASIA score improvement had a positive correlation with the age at injury (r = 0.505, p = 0.023). The SF-36 data at 6 months and final follow-up were not as satisfactory as the improvement in ASIA scores, and almost one-third of patients expressed dissatisfaction with their final symptoms. For patients who were older than 65 years at injury, the mean follow-up Walking Index for Spinal Cord Injury (WISCI) score was statistically lower than it was in younger patients. The presence of spasticity or neuropathic pain at follow-up was not related to age, sex, ASIA motor score, or WISCI outcome. CONCLUSIONS: Surgical intervention can be safely applied in patients with TCCS. Significant improvement of ASIA score was achieved during the first 6-month period of follow-up. Factors including type of lesion, timing of surgery within or after 4 days of injury, and surgical approach were not significantly associated with final ASIA score. The improvement in the ASIA motor score was positively correlated with age at injury. No significant correlation was found between or among the presence of spasticity, neuropathic pain, and ASIA score at final visit. Almost one-third of patients were not satisfied with their final symptoms.

RESUMO

AIM: In patients with traumatic spinal cord injury, several studies correlate neurological impairment and radiological findings. However, little information is available about this correspondence in the particular group of acute traumatic central cord syndrome. The object of the present work was to describe the clinical and radiological features of a series of patients presenting with acute traumatic central cord syndrome and to analyze clinical and radiological correlations on admission and at last follow-up. METHODS: Retrospective review of 15 patients diagnosed of acute traumatic central cord syndrome between 1995 and 2005. Global motor score and motor score in upper extremities were determined on admission and at last follow-up (6 months-4 years, mean 16 months). Plain films, cervical computed tomography and magnetic resonance (MR) were performed in every patient and retrieved for the study. In seven patients, serial MR studies were performed during follow-up. Clinical and radiological correlations were statistically analyzed with non-parametric tests. RESULTS: Cervical spondylosis appeared associated with older age, falls, and absence of fracture. Spinal cord edema was the most common finding in MR studies but hemorrhage was also observed. The length of spinal cord edema significantly correlated with initial motor score. The decrease in T2-weighted hyperintensity in serial MR studies correlated with the gain of motor power in upper limbs at last follow-up. CONCLUSION: Elderly patients with more degenerated cervical spines commonly develop acute traumatic central cord syndrome after incidental falls. Length of spinal cord edema correlates with neurological impairment on admission and may provide significant prognostic information.

RESUMO

STUDY DESIGN: Case report. OBJECTIVE: To present a patient with central cord syndrome injury after total hip arthroplasty performed under general endotracheal anesthesia. SUMMARY OF BACKGROUND DATA: Central cord syndrome, a common injury usually sustained as a result of an extension injury to the cervical spine, often occurs in geriatric patients with underlying spondylotic changes. The injury results in weakness and sensory changes, which are more pronounced in the upper than in the lower extremities. Patients with this syndrome experience variable return of function, but some degree of residual deficit and spasticity is likely. METHODS: The medical record, including the intraoperative anesthesia records, operative notes, progress notes, discharge summary, clinic notes, and radiology studies and reports, was reviewed. RESULTS: The patient developed signs of central cord syndrome after total hip arthroplasty. Despite nonoperative intervention, including physiotherapy, the patient's upper and lower extremity weakness continued. Magnetic resonance imaging revealed evidence of cervical cord compression, and the patient underwent a cervical laminectomy, which produced mild improvement in his symptoms. CONCLUSIONS: To avoid life-altering complications, it is important to evaluate the cervical spine (especially in the elderly), avoid neck extension during intubation, and use careful airway management in patients with suspected stenosis/spondylosis.

RESUMO

BACKGROUND: The purpose of this study was to better define the incidence and characteristics of patients with spinal cord injury without radiographic abnormality (SCIWORA), using the database of the National Emergency X-Radiography Utilization Study (NEXUS). METHODS: This was a prospective, observational study of blunt trauma patients in 21 U.S. medical centers undergoing plain cervical radiography. SCIWORA was defined as spinal cord injury demonstrated by magnetic resonance imaging, when a complete, technically adequate plain radiographic series revealed no injury. RESULTS: Of the 34,069 patients entered, there were 818 (2.4%) with cervical spine injury, including 27 (0.08%) patients with SCIWORA. Over 3,000 children were enrolled, including 30 with cervical spine injury, but none had SCIWORA. The most common magnetic resonance imaging findings among SCIWORA patients were central disc herniation, spinal stenosis, and cord edema or contusion. Central cord syndrome was described in 10 cases. CONCLUSION: In the large NEXUS cohort, SCIWORA was an uncommon disorder, and occurred only in adults.
