Avulsion of abductors from hip is a debilitating complication after total hip arthroplasty performed through a trans-gluteal approach. It results in intractable pain, Trendelenberg limp and instability of the hip. Techniques described for repairing these abductor tears including direct trans osseous repairs, endoscopic repair techniques, Achilles tendon allograft, Gluteus Maximus and Vastus Lateralis muscle transfers. The aim of our study was to assess improvement in pain, limp and abductor strength in patients operated upon surgically for confirmed abductor avulsion using a modified trans osseous repair and augmentation of repair with a Graft Jacket allograft acellular human dermal matrix (Graft jacket; Wright Medical Technology, Arlington, TN). In this prospective study we include 18 consecutive patients with hip abductor avulsions following a primary total hip arthroplasty through Hardinge approach for osteoarthritis. All the patients presented with pain around lateral aspect of hip, walking with a significant Trendelenberg limp and used a crutch or a stick in the opposite hand. Diagnosis was made by clinical examination and confirmed by MRI scans.Introduction
