Abstract：Objective To summarize the mid-term efficacy of autogenous femoral head transplantation to reconstruct the acetabulum in the treatment of hip dysplasia. Methods Data of 21 patients with hip dysplasia treated with autogenous femoral head transplantation to reconstruct the acetabulum and total hip arthroplasty in the Department of Joint Surgery of Chifeng Hospital from July 2012 to July 2016 was retrospectively analyzed.Among them，there were 6 males and 15 females，aged from 32 to 66 years old，with an average age of (50.67±8.62)years.The Harris scores were collected before surgery and at the last follow-up.The imaging evaluation included preoperative Xrays of the hip joints and X-rays of the hips at the last follow-up to assess the position of the artificial joint and the healing of the femoral head bone graft.Results All 21 patients in this group were followed up.The follow-up time ranged from 52 to 96 months，with an average of (75.05±12.14)months.The preoperative Harris score was 21~42 points，with an average of (31.33±5.77)points，and at the last follow-up，it was 83~94 points with an average of (88.81±2.98)points.Two of the patients showed bone resorption at the femoral head bone graft on hip X-rays at 6 months and 8 months after surgery，but the position of the acetabular prosthesis and bone ingrowth were good.Conclusion The use of autogenous femoral head transplantation to reconstruct the acetabulum and total hip replacement in the treatment of hip dysplasia has a satisfactory midterm effect，and there are no related complications such as prosthesis loosening.
