Total joint arthroplasty may be considered as a last option to treat osteopetrosis associated with osteoarthritis or some other complications. Many intraoperative challenges need to be overcome when performing arthroplasty so we present a 36 years old woman with autosomal dominant (AD) osteopetrosis who was suffering a painful nonunion of subthrocanteric fracture, referred to our center in Jun 2010. This patient had previously been operated on for three times and at the last time she underwent open reduction and internal fixation(ORIF) with dynamic hip screw (DHS) which resulted in nonunion associated with destruction of femoral head ,therefore we preferred to do uncemented total hip arthroplasty for the patient. we encountered some difficulties especially during preparation of the femoral canal. The short term post operative clinical and radiological results are good and the patient is walking independently and is pain free at the moment .
