Methods: 1.Dissect and position the MIB of the SGN and other important nerves and vasculars on 100 hips of 50 cadavers. Measure the relative distances from the MIB to the surrounding skeletal anatomic landmarks and calculate their 99% medical reference ranges in the crowd by which we can determine the surface projection of the MIB and the secure region. Simulated operations of minimal incision hip arthroplasty through modified Hardinge approach was implemented in the region on 6 hips of 3 cadavers to verify the security by analyzing the injury of nerves and vasculars in the region after operations.2.The anatomic result of this study was applied to clinical operations. 26 cases of hip arthroplast were performed through modified Hardinge approach and 26 patients were performed hip arthroplast through traditional Hardinge approach. Data of operation and postoperation has been analysed and compared. Results: 1. the average ratios of relative distances from the surface pro
