The mini-incision approach to total hip arthroplasty.
Total hip arthroplasty (THA) usually involves an incision of approximately 20 to 25 cm long. Surgeons recently have begun to question the need for such a long incision and are developing less invasive approaches to THA. A mini-incision approach to THA promotes shorter hospital stays, faster rehabilitation, and an increase in patient satisfaction without a detrimental effect on outcome. The surgical technique is based on the classic Moore approach to the hip. The incisions measure 6 to 10 cm in length, and the surgery involves significantly less deep soft-tissue disruption. All the basic tenets of THA are respected and visualization is maintained throughout the procedure for proper placement of the components. Mini-incision THA offers a safe and effective alternative to THA performed through a larger incision. Obese patients typically are not good candidates. Patients with severe hip dysplasia or those undergoing revision surgery require a wider exposure to perform the arthroplasty to ensure the best possible result. In properly selected patients, however, THA can be performed through an abridged mini-incision without compromising the results or exposing the patient to additional risk.
