Percutaneous endoscopic lumbar discectomy(PELD) for patients with single segment lumbar disc herniation complicated with degenerative lateral curvature and kyphosis

Objective To evaluate the short-term effect of percutaneous endoscopic lumbar discectomy(PELD) on patients with single segment lumbar disc herniation complicated with degenerative lateral curvature and kyphosis. Methods Twenty-two patients with single segment lumbar disc herniation complicated with degenerative lateral curvature and kyphosis were selected, all of the patients had different degrees of lumbar and unilateral lower limb nerve root radiation pain. The data of the 22 patients were analyzed retrospectively, the mean follow-up was 18 months. The effect was evaluated before operation, one month, 3 months and 18 months after operation, according to the lumbar spine JOA and Oswestry dysfunction index (ODI). At the end of the follow-up period, according to the MacNab evaluation criteria, the short-term effect of the operation was evaluated. Results There was significant differences in the Leg pain JOA score and ODI index of the patients before and after operation(P<0.05). According to the MacNab evaluation criteria: there were excellent in 11 cases (50%), good in 8 cases (36.4%), medium in 2 cases(9%), poor in 1 case (4.5%), the excellent and good rate was 86.4%. Conclusions Percutaneous endoscopic lumbar discectomy can effectively reduce the leg pain symptoms of patients, and achieve satisfactory results. It is the minimal treatment of patients with single segment lumbar disc herniation complicated with degenerative lateral curvature and kyphosis, and it is worthy of promotion.
