Traditional posterior lumbar fusion surgery can cause long-term complications such as muscle atrophy and adjacent segment degeneration due to the damage to the paraspinal muscles and rigid fixation.
The 4 patients in this case report all presented with the chief complaint of low back pain accompanied by lower limb pain.
The patient was diagnosed with lumbar degenerative diseases through clinical manifestations, imaging examinations, and physical examinations, including lumbar disc herniation, lumbar instability, and lumbar spondylolisthesis.
A retrospective analysis was conducted on the clinical data of 4 patients who underwent percutaneous polyether ether ketone (PEEK) rod pedicle screw fixation system combined with unilateral biportal endoscopic technique for lumbar degenerative diseases in our hospital from May 2022 to September 2022. Surgical data, imaging changes, and follow-up results were statistically analyzed.
All surgeries were successfully completed, with all 4 patients undergoing single-segment fixation. The mean operation time was 162.50 ± 27.54 minutes, intraoperative blood loss was 70±24.49 mL, average bed rest time was 2.25 days, and average hospital stay was 5.5 days. The Visual Analogue Scale scores for low back pain and leg pain and the Oswestry Disability Index of the patients showed a gradually decreasing trend after surgery, and were significantly improved at the last follow-up compared with those before surgery, with statistically significant differences (P < .05). There were no significant changes in the cross-sectional area of the multifidus muscle, fat infiltration rate, range of motion of the operated segment, and disc height index at the last follow-up compared to preoperative values (P > .05). No complications, such as screw loosening or PEEK rod breakage occurred at the last follow-up.
Percutaneous PEEK rod pedicle screw fixation system combined with unilateral biportal endoscopic technique is feasible for the treatment of lumbar degenerative diseases.
传统的后路腰椎融合手术会因对椎旁肌肉的损伤和坚强固定而导致长期并发症，如肌肉萎缩和相邻节段退变。
本病例报告中的4例患者均以腰痛伴下肢疼痛为主诉就诊。
通过临床表现、影像学检查及体格检查，患者被诊断为腰椎退行性疾病，包括腰椎间盘突出症、腰椎不稳和腰椎滑脱。
对2022年5月至2022年9月在我院接受经皮聚醚醚酮（PEEK）棒椎弓根螺钉固定系统联合单侧双通道内镜技术治疗腰椎退行性疾病的4例患者的临床资料进行回顾性分析。对手术数据、影像学变化及随访结果进行统计学分析。
所有手术均顺利完成，4例患者均行单节段固定。平均手术时间为162.50±27.54分钟，术中出血量为70±24.49毫升，平均卧床时间为2.25天，平均住院时间为5.5天。患者术后腰痛和腿痛的视觉模拟评分及Oswestry功能障碍指数呈逐渐下降趋势，末次随访时与术前相比有显著改善，差异有统计学意义（P<0.05）。末次随访时多裂肌横截面积、脂肪浸润率、手术节段活动度及椎间盘高度指数与术前相比无显著变化（P>0.05）。末次随访时未发生螺钉松动或PEEK棒断裂等并发症。
经皮PEEK棒椎弓根螺钉固定系统联合单侧双通道内镜技术治疗腰椎退行性疾病是可行的。
