Abstract:[Objective] To summarize the characteristics of lumbar disc herniation in armed police officers and soldiers, investigate the clinical efficacy of CT guided endoscopic discectomy (CTED). [Methods] A retrospective study was conducted on 92 armed police officers and soldiers who underwent CTED for lumbar disc herniation in our hospital from June 2010 to December 2020. Clinical and imaging data were evaluated. [Results] All the 92 patients were successfully operated on, with average operation time of (63.5±19.7) min, average num- ber of intraoperative CT scans of (7.8±1.7) times and average follow-up time of (52.3±38.3) months. With time preoperatively, at discharge and the latest follow-up, the VAS score [(7.4±0.9), (1.6±0.7), (1.1±0.3), P＜0.05] and ODI scores [(74.5±11.7), (18.6±3.0), (14.4±1.3), P＜ 0.05] significantly reduced, while JOA score significantly increased [(9.0±3.2), (26.1±2.3), (28.0±1.2), P＜0.05]. Radiographically, com- pared with those preoperatively, the height of the vertebral space at the involved level significantly decreased [(9.1±1.3) mm, (8.6±1.3) mm, (8.0±1.2) mm, P＜0.05], whereas the lumbar lordotic angle significantly increased [(22.3±4.6)°, (27.7±4.9)°, (27.0±3.6)°, P＜0.05] postopera- tively. [Conclusion] The CTED used in the treatment of lumbar disc herniation in armed police officers and soldiers has the advantages of minimally invasive surgery, accurate location, high safety, quick recovery and good curative outcome.
