Unusual cup reconstruction of massive acetabulum perforation in neglected femoral neck osteoporotic fracture: A case report.

Introduction: Uncemented total hip for neglected nonunion femoral neck fracture hopefully could minimize the post operative complications. Nevertheless, due to plasticity of the brittle osteoporotic bone, unexpected fracture may occur. We presented an unusual reconstruction of acetabulum which was accidently perforated during uncemented cup insertion.
