Effects of surgery with the YESS technique on lumbar range of motion and limb function in patients with lumbar disc herniation / 中国基层医药

ABSTRACT

Objective:To investigate the effects of surgery with the Yeung endoscopic spine system (YESS) technique on lumbar range of motion and limb function in patients with lumbar disc herniation.Methods:A total of 148 patients with lumbar intervertebral disc herniation admitted to Liaocheng Second Hospital Affiliated to Shandong First Medical University from April 2018 to April 2021 were included in this study. They were randomly divided into control and observation groups ( n = 74/group). The control group was treated with laminectomy, and the observation group was treated with an intervertebral foramen mirror YESS. The lumbar range of motion, Oswestry disability index score, and incidence of surgical complications were compared between the two groups. Results:At postoperative 7 days, ranges of motion in lumbar flexion, lumbar extension, left lumbar lateral flexion, and right lumbar lateral flexion in the observation group were (87.45 ± 7.38)°, (26.87 ± 3.41)°, (28.58 ± 3.41)°, (28.39 ± 3.41)°, which were significantly higher than (68.98 ± 6.51)°, (15.69 ± 3.23)°, (18.69 ± 2.32)°, (14.56 ± 2.96)° in the control group ( t = 16.15, 20.48, 20.63, 26.35, all P < 0.001). At postoperative 7 days, the Oswestry Disability Index in each group was significantly decreased compared with before treatment (both P < 0.05). At postoperative 7 days, the score of each dimension of the Oswestry Disability Index in the observation group was significantly lower compared with the control group ( t = 49.13, 50.20, 54.78, 37.79, 32.04, 36.68, 43.69, 28.92, 39.31, 64.12, all P < 0.001). There were no significant differences in the incidences of perioperative incision infection, nerve injury, cerebrospinal fluid leaks, lumbar spondylolisthesis, and foot drop between the two groups (all P > 0.05). Conclusion:Treatment of lumbar intervertebral disc herniation with the YESS technique is helpful to improve lumbar mobility and reduce lumbar dysfunction and is highly safe.
