PurposeThis study compared the recovery of motor function and the safety of early and delayed surgical intervention in patients with central cord syndrome (CCS).MethodsPubMed, Embase, Cochrane Library, and Web of Science were employed to retrieve the targeted studies published from inception to February 19, 2023. Comparative studies of early versus delayed surgical decompression in CCS based on American Spinal Injury Association motor score (AMS) recovery, complication rates, and mortality were selected. The statistical analyses were performed using STATA 16.0 and RevMan 5.4.ResultsOur meta-analysis included 13 studies comprising 8424 patients. Results revealed that early surgery improved AMS scores significantly compared with delayed surgery, with an increase in MDs by 7.22 points (95% CI 1.98-12.45; P = 0.007). Additionally, early surgery reduced the complication rates than delayed surgery (OR 0.53, 95% CI 0.42-0.67, P < 0.00001). However, no significant difference was observed in mortality between the two groups (OR 0.97; 95% CI 0.75-1.26; P = 0.84).ConclusionsEarly surgical decompression for CCS can improve motor function and reduce the incidence of complications without affecting the mortality rate in patients. Future research should focus on investigating and analyzing the optimal window period for early CCS surgery. Additionally, the timing of surgery should be determined based on the patient's condition and available medical resources.© 2024.
