This study aims to determine the efficacy of early surgical decompression (within 24 hours) of traumatic central cord syndrome patients in comparison with conservative management for central cord syndrome to determine a line of management to these cases. <strong>Methods: </strong>60 patients suffering from acute traumatic central cord syndrome with various neurological deficits were divided into 2 groups, group A (conservatively managed) and group B (surgically managed). Patients in group B were operated upon within 24 hr. of trauma by posterior decompression. Clinical assessment of each patient on admission, discharge and 3 months follow-ups was done using the ASIA Impairment Scale, FIM, Ashworth scale, bladder function, and neuropathic pain symptoms. <strong>Results:</strong> Data collected from both groups showed, group A (the conservative group) consisted of 22 male (73.3%) and 8 female subjects (26.6%) with a mean age of 57.5 years while in group B (surgical group) the sample consisted of 20 male (66.6%) and 10 female subjects (33.3%) with a mean age of 58.6 years. There was an improvement in our study—according to ASIA and FIM scales—in 8 patients of 30 (26.6%) in the conservative group. In the surgical group, improvement in 16 patients (53.3%). <strong>Conclusions:</strong> Early surgical decompression with laminectomy and duroplasty can be considered a reliable modality in the management of traumatic CCS and can effectively reduce the secondary injury of the spinal cord and consequent deterioration with less hospital stay.展开更多

Although multiple studies have investigated potential new therapies for the treatment of acute SCI, outcomes and management protocols aimed at ameliorating neurologic injury in patients remain ineffective. More recent clinical and basic science research have shown surgical interventions to be a potentially valuable modality for treatment; however, the role and timing of surgical decompression, in addition to the optimal surgical intervention, remain one of the most controversial topics pertaining to surgical treatment of acute SCI. As an increasing number of potential treatment modalities emerge, animal models are pivotal for investigating its clinical application and translation into human trials. This review critically appraises the available literature for both clinical and basic science studies to highlight the extent of investigation that has occurred, specific therapies considered, and potential areas for future research.展开更多

In the present study, we established a rat model of acute spinal cord injury by cerclage. The cerclage suture was released 8 or 72 hours later, to simulate decompres-sion surgery. Neurological function was evaluated behaviorally for 3 weeks after surgery, and tumor necrosis factorα immunoreactivity and apoptosis were quantiifed in the region of injury. Rats that underwent decompression surgery had significantly weaker immunoreactivity of tumor necrosis factorα and signiifcantly fewer apoptotic cells, and showed faster improvement of locomotor function than animals in which decompression surgery was not performed. De-compression at 8 hours resulted in signiifcantly faster recovery than that at 72 hours. These data indicate that early decompression may improve neurological function after spinal cord injury by inhibiting the expression of tumor necrosis factorα.展开更多
