Abstract
Objective: To observe the clinical effect percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of single lumbar disc herniation. Methods: From August 2017 to June 2019, 42 patients with low lumbar single segment lumbar disc herniation were treated with percutaneous transforaminal endoscopic discectomy surgery in our hospital. The operation time, incision size, bleeding volume and hospitalization time were recorded respectively. The patients were evaluated before operation, 1 month and 6 months after operation. Visual analogue scale (VAS) and assessment were used to evaluate the lumbocrural pain. The JOA score and the Oswestry disability index (ODI) were used to evaluate the lumbar function, and the modified macnab score was used to evaluate the clinical effect in the last follow-up. Results: All the 42 patients successfully completed the operation without any other operation. There were no severe complications such as dural injury and nerve root injury. The operation time was (76.98 ± 8.58) min, the incision size was (8.45 ± 1.2) mm, the bleeding volume was (20.14 ± 2.93) ml, and the hospitalization time was (4.55 ± 1.13) d. One month and six months after the operation, the visual analogue scale (VAS), the evaluation of lumbar function (Oswestry) and the disability index (ODI) were significantly improved compared with those before the operation (P < 0.05). The last follow-up evaluation of the clinical effect of modified macnab: excellent in 30 cases, good in 8 cases, fair in 3 cases and poor in 1 case. The excellent rate was 90.47%. One patient developed back pain and discomfort. One case recurred. Conclusion : The treatment of low lumbar but segmental lumbar disc herniation with percutaneous intervertebral foramen, with small incision, less bleeding and quick recovery, can improve the pain and dysfunction of patients.
