Total hip arthroplasty in a patient with a contralateral hemipelvectomy.

Hemipelvectomy is a rare procedure performed for tumor resection or trauma. The limb may be spared, and the patients often require extensive rehabilitation. We report the outcome of a total hip arthroplasty (THA) in a patient with endstage hip arthritis in a high dislocated hip contralateral to a remote, traumatic hemipelvectomy. To our knowledge this is the first reported case with mid-term follow-up of a patient undergoing THA for degenerative, traumatic hip dislocation with a contralateral external (limb-sacrificing) hemipelvectomy. Patient history, surgical details, and follow-up 5 years from the index arthroplasty are presented. This case report documents that THA after hemipelvectomy can be a durable procedure, and provide reliable pain relief and improvement in function at intermediate follow-up using good surgical techniques, and with the use of noncemented implants.
