Diagnosis and Management of Hip Abductor Insufficiency

Greater Trochanteric Pain Syndrome (GTPS) is a common cause of lateral hip pain, with an incidence of 1.8 per 1000 patients, most commonly occurring between the fourth and sixth decades of life. When GTPS fails to improve with conservative management, hip abductor insufficiency should be suspected. The diagnosis of hip abductor insufficiency is made by a combination of physical exam findings and imaging studies, with Magnetic Resonance Imaging (MRI) being the diagnostic study of choice. Initial conservative management consists of activity modification, physical therapy, non-steroidal anti-inflam- matories and corticosteroid injections. If conservative management fails, this may be suggestive of a hip abductor tear. Surgical intervention has been shown to provide excellent outcomes, and may be necessary if a tear is present. The purpose of this paper is to review and raise awareness of hip abductor insufficiency as an under- diagnosed and under-treated condition that can limit patient mobility and quality of life.
