[Comparison of clinical efficacy of unilateral dual-channel endoscopy and large-channel endoscopy techniques in the treatment of lumbar spinal canal stenosis].
摘要
OBJECTIVE: To explore clinical efficacy and imaging results of unilateral biportal endoscopy (UBE) and large-channel endoscopy techniques in treating lumbar spinal stenosis (LSS). METHODS: (10 cases). Operation time, hospital stay and postoperative complications between two groups were record and compared;visual analog scale (VAS) and Oswestry disability index (ODI) of lumbar spine, Japanese Orthopaedic Association (JOA) were compared respectively before operation, 3 days, 3 and 6 months after operation;area changes of dural sac in lumbar MRI before operation and 3 days after operation were compared. RESULTS: <0.05). CONCLUSION: Both UBE technology and large-channel endoscopic technology could achieve satisfactory therapeutic effects in the treatment of LSS. However, UBE has more thorough decompression and area of dural sac expansion is better than that of the large-channel.
