- Objective To compare the outcomes of early (within 1 month after foot drop) decompression versus late (1 month or more after foot drop) decompression in order to determine the optimal surgical intervention timing for lumbar degenerative diseases. Methods The MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and SCOPUS electronic databases were searched for relevant articles published until May 2021 were conducted. Cochrane Collaboration guidelines were used for data extraction and quality assessment. Outcomes of interest were manual muscle testing (MMT) and recovery rate (MMT >= 4) for foot drop in lumbar degenerative diseases. Results Six clinical studies were retrieved, including 312 randomized participants. One hundred fifty-seven patients underwent early decompression surgery, and 155 underwent late decompression surgery. There were significant differences between the two groups in recovery rate (95% confidence interval [CI] 1.59, 2.57) and neurological improvement (95% confidence interval [CI] 0.21, 1.66). Early surgical decompression provided better recovery rate and neurological improvement for foot drop in lumbar degenerative diseases than late surgical decompression. Conclusion Early surgical decompression within was beneficial in terms of recovery rate and neurological improvement compared with late surgery. Early surgical decompression (within 1 month) is recommended for patients with foot drop in lumbar degenerative diseases.
