Abstract:

Total hip replacement (THR) in the elderly after acetabular fracture presents unique challenges to the orthopedic surgeon. Technical challenges however include infection, residual pelvic deformity, acetabular bone loss with ununited fractures, osteonecrosis of bone fragments. The use of modern implants and alternative bearing surfaces should improve outcomes further. The objective of our study is to investigate the clinical and functional outcome in an elderly population with acetabular fractures after low-energy trauma treated acutely with a total hip arthroplasty and autologous bone grafting of the acetabulum.  We report the case of a 72 years old man, operated for a left acetabular fracture with a total hip arthroplasty and autologous bone grafting of the acetabulum.the prosthesis used was a cementless dual mobility total hip prosthesis for reconstruction with 3 pre-shaped, malleable and separable fixation flanges and a Positioning hook inserts. The prosthesis was stable and there were no signs of loosening of the acetabular component or stem.
