Superior Gluteal Reconstruction for Severe Hip Abductor Deficiency

Abductor tendon tears are one of the common causes of recalcitrant laterally based hip pain and dysfunction. In most cases, abductor tendon tears are associated with chronic nontraumatic tearing of the gluteus medius tendon. Restoring abductor function of the hip by primary repair of the gluteus medius tendon has been reported to have good and excellent outcomes. However, primary repair might not be as effective for chronic detachment of the gluteus medius tendon with a wide separation from the femoral footprint or severe tendon loss. The lack of tendinous foot for repair and the intrinsically degenerative condition of the tendon may create high tension at the repair site thereby predisposing to surgical failure. We believe that the use of soft-tissue allograft from the Achilles tendon or human dermal allograft may help strengthen the surgical site. We describe a superior gluteal reconstruction technique that is suitable for cases with abductor tendon tear with severe tendon loss
