Osteopetrosis is a rare disease. When fractures are encountered, fixation is extremely difficult. A 38-year-old man with osteopetrosis who sustained a displaced Pauwels type IV fracture with 3 failed internal fixations required total hip arthroplasty. Two main problems were perceived during preoperative planning: the removal of failed and broken metalwork and reaming of the tight intramedullary canal to allow seating of the femoral stem. We present technical solutions to aid the surgeon in the management of this difficult type of case using custom-made tungsten carbide instrumentation.
