  •   Objective  To observe the clinical efficacy and safety of targeted broken ligamentum flavum method of unilateral biportal endoscopy in the treatment of lumbar spinal stenosis.  Methods  A total of 86 patients with lumbar disc herniation admitted to the 960th Hospital of the PLA Joint Logistics Support Force from January 2020 to January 2022 were retrospectively analysed.Patients were divided into 2 groups based on the surgery they had undergone: the targeted broken ligamentum flavum method group (TBM group, 39 cases) and the conventional clamshell method group (CCM group, 47 cases).Using visual analogue scale (VAS), oswestry disability index (ODI) and Japanese orthopaedic association (JOA) scores to assess the pain and functional parameters to record surgical complications.  Results  The mean operating time and bleeding volume were (58.6±14.5) min and (42.6±10.6) mL and the length of the incision was (2.93±0.23) cm in the TBM group, and (81.4±17.6) min and (63.8±18.6) mL and (3.12±0.43) cm in the CCM group, respectively, with statistically significant differences between the 2 groups (all P < 0.001).In contrast, there was no significant difference in the hospital stay time between the 2 groups (P=0.293).No significant differences were observed between the 2 groups in preoperative indices (VAS, ODI, JOA), all P>0.05;no statistically significant differences were observed between the 2 groups postoperatively (all P>0.05).There were significant differences between the 2 groups at different time points after surgery (all P < 0.05).Patients in both groups showed a significant improvement in their postoperative scores compared to their preoperative scores (all P < 0.05).There were no serious complications and there were no significant differences in the short-term between the 2 groups (P>0.05).  Conclusion  The targeted broken ligamentum flavum method of unilateral biportal endoscopy could be a kind of ideal treatment for lumbar spinal stenosis, which could be further promoted in the clinical practice.
