Application and Therapeutic Observation of Lower Articular Process Anchoring Technique in Endoscopic Lumbar Spinal Canal Decompression Surgery
Objective:Observing the safety and effectiveness of the lower articular process anchoring technique under a sin-gle hole coaxial endoscope in the treatment of lumbar spinal stenosis(LSS)through percutaneous endoscopic unilateral laminotomy and bilateral decompression(Endo-ULBD).Methods:A retrospective study was conducted on 33 patients with LSS treated with arthroscopic circular lower articular process anchoring technique.The preoperative and postoperative pain visual analogue scale(VAS)scores and Oswestry disability index(ODI)scores were compared,and postoperative complications were observed.The efficacy was evaluated using the MacNab standard.Results:All patients successfully completed the surgery and received follow-up,with a surgical duration of 67-115 min.One patient had intraoperative nerve root outer membrane injury.The postoperative follow-up VAS score and ODI score were statistically significant compared to preoperative results(P＜0.05).After 12 months of surgery,MacNab criteria were used to evaluate 25 cases as excellent,5 cases as good,and 3 cases as fair,with an excellent and good rate of 90.9％.Conclusion:The lower articular process anchoring technique under circular sawing is simple to operate,safe and effective in Endo-ULBD treatment of LSS,and is worthy of clinical promotion and application.
