Surgical challenges in complex primary total hip arthroplasty.

Abstract

Complex primary total hip arthroplasty (THA) is defined as primary THA in patients with compromised bony or soft-tissue states, including but not limited to dysplastic hip, ankylosed hip, prior hip fracture, protrusio acetabuli, certain neuromuscular conditions, skeletal dysplasia, and previous bony procedures about the hip. Intraoperatively, provisions must be made for the possible use of modular implants and/or bone grafts. In this article, we review the principles of preoperative, intraoperative, and postoperative management of patients requiring a complex primary THA.
