Objective To investigate the clinical application and effect of hip arthroscopy minimally invasive technique in the treatment of calcified diseases of glenoid lip of hip joint.Methods Six cases were selected in this study. All the cases were diagnosed as calcification of acetabular labrum by X-ray, CT and MRI before operation. The ɑ angle of hip and CE angle were measured before operation. All cases were confirmed to be calcification of acetabular labrum by hip arthroscopy, and the Calcification foci of glenoid lip was cleaned under hip arthroscopy and suture of acetabular labrum was performed.Pincer and Cam deformity was performed in patients with FAI. The results were evaluated according to VAS and Harris scores, and the average follow-up was 6 months.Results All patients were followed up all the way, the average ɑ angle was 56.2 degrees before operation, and the angle of 5 patients was more than 55 degrees. Patients had significantly improved hip function and greatly improved quality of life after operation. For 6 months after operation, six hip VAS scores decreased from a preoperative average of 7.6 points to a postoperative average of 1.8 points ( p <0.01), and Harris scores increased from a preoperative 63.3 points to a postoperative 86.1 points (p <0.01).Conclusion Calcification of acetabular labrum is a kind of degenerative disease which can cause hip pain, which is extremely rare, with unknown etiology, no specific symptoms and sign. Hip arthroscopy can clean up the lesion thoroughly and suture the acetabular labrum, effectively improve the quality of life of patients, but the etiology of calcification of hip pelvic lip, the progression of non-interventional disease and the long-term effect of endoscopic treatment still need further study and observation.
