Acetabular transverse nonunion treated by a hemispherical press-fit cup and structural autologous bone graft.

Nonunion of acetabular fractures are uncommon, and their treatment can be a rather demanding procedure. Acute total hip arthroplasty could be a possible treatment choice, especially when there is a femoral head arthritis. We report a case of transverse acetabular fracture nonunion treated by a cementless hemispherical press-fit cup and autologous structural bone graft. At 10 years follow-up, the graft was integrated, the cup was stable, and the patient was completely recovered.
