PurposeAlthough there have been numerous studies aimed at determining the effects and safety of early vs. late surgical decompression for traumatic cervical spinal cord injury, controversies still exist regarding the optimal timing of surgery for this serious spinal trauma. This study was conducted to evaluate the effectiveness and safety of early vs. late surgical decompression for lower cervical spine trauma associated with spinal cord injury.MethodsA retrospective review of was performed on consecutive patients who underwent surgical decompression for lower cervical (C3-C7) spine trauma associated with spinal cord injury at six institutions across China from January 2007 to January 2012. These patients were analysed according to the timing of surgical intervention. The early group comprised patients who underwent surgery within the first 72 hours after being injured, whilst the late group comprised patients who underwent surgery after the first 72 hours. For analysis of neurologic improvement, patients who had completed a follow-up of at least six months were assessed. Other outcomes analysed were hospitalisation periods, complications and mortality.ResultsA total of 595 patients were identified (456 men and 139 women at an average age of 41.4 years), with 212 in the early group and 383 in the late group. Patients in both groups had made a significant neurologic improvement in the final follow-up, but no statistically significant difference was noted between groups. Patients in the early group had a significantly shorter hospital stay (15.4 vs. 18.3 days, p <0.001) but realised no benefits in terms of intensive care unit length of stay and ventilator days. No significant differences were identified between groups with regards complications (pneumonia, pulmonary embolism, wound infection, sepsis and urinary tract infection). Compared with the late group, the early group had a significantly higher incidence of postoperative neurological deterioration (6.6 vs. 0.7 %, p <0.001) and mortality (7.1 vs. 2.1 %, p = 0.003).ConclusionThe timing of surgery for patients sustaining traumatic lower cervical spine injury with neurological involvement did not affect neurological recovery. Early surgical intervention was associated with a higher incidence of mortality and neurological deterioration compared with late surgical intervention, indicating that surgery after the first 72 hours might be relatively safe.
