Hip dysplasia is a congenital defect of the hip joint in infants with mismatch of the femoral head and the acetabulum. It can be treated in infants via conservative or surgical containment of the femoral head. In developing countries cases of hip dysplasia are often overlooked and neglected. Therefore, many cases of severe coxarthrosis with dislocations of the femoral head can be observed. The dislocation complicates the implantation of a hip prosthesis. This article shows a novel technique in total hip replacement in a case report.
