[Effect of Quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy treatment in patients with L 5, S 1 lumbar disc herniation].

OBJECTIVE: lumbar disc herniation. METHODS: , who were initially enrolled for the PELD treatment. Among them, 66 patients were successfully treated with PELD (group A), and the other 34 patients failed to perform puncture, catheterization, or microscopical operation due to the influence of iliac bone and other peripheral bone structures and treated with alternative surgical plans. By analyzing the X-ray films of lumbar vertebrae (including bilateral ilium) of the two groups before operation, the concept of ilium height rate and ilium angle rate was put forward innovatively. The ilium height rate and ilium angle rate of the two groups were measured and compared, and the diagnostic critical points of ilium height rate and ilium angle rate were determined by ROC curve analysis. RESULTS: =0.000). CONCLUSION: intervertebral disc herniation, when the ilium height rate is greater than 0.71 and/or the ilium angle rate is greater than 0.75. Other surgical plans such as transpedicular approach, transpedicular approach, or open surgery, should be recommended to reduce the risk of surgery and the pain of patients.
