• ABSTRACT
    • Abductor insufficiency can cause abnormal gait, lateral hip pain, and abduction weakness in both native and prosthetic hips. In the setting of total hip arthroplasty (THA), abductor insufficiency may occur secondary to iatrogenic injury to the superior gluteal nerve or gluteus medius muscle, adverse local tissue reactions owing to metal-associated prosthetics, and osteolysis owing to bearing wear or infection. Surgical reconstruction of the abductor complex is indicated for patients with chronic tears who have pain, weakness, limp, and/or instability. This article reviews the pearls and pitfalls of surgical reconstruction options for abductor insufficiency following THA.
