The use of autologous femoral head grafts for acetabular reconstruction has been described but few data is available about clinical results the rates of non-union or aseptic loosening of acetabular components. Methods In a retrospective approach 101 patients with 118 THA requiring autologous femoral head grafts to the acetabulum because of DDH were included. Six patients had died another 6 were lost to follow-up and 104 hips were available for clinical and radiological evaluation at a mean of 68 15 13 to 159 months. Results The average Merle d Aubigné hip score improved from 9 to 16 points. Seven implants had to be revised due to aseptic loosening 6.7 . The revisions were performed 90 34 56 to 159 months after implantation. The other hips showed a stable position of the sockets without any signs of bony non-union severe radiolucencies at the implant-graft interface or significant resorption of the graft. Conclusion The use of autologous femoral head grafts with cementless cups in primary THA can achieve promising short- to midterm results in patients with dysplastic hips. Keywords Bone graft developmental dysplasia of the hip primary total hip arthroplasty THA Background Stable and correct positioning of the socket in cases of developmental dysplasia of the hip DDH with subsequent severe bone stock deficiencies is one of the most challenging problems in total hip arthroplasty THA . This is especially true in Crowe .
