Surgical Treatment of Gluteus Medius Tears Augmented With Allograft Human Dermis

Greater trochanteric pain syndrome can be caused by gluteus medius and minimus tendinopathy/tears and chronic trochanteric bursitis. Specifically, moderate-to-severe abductor tendon tears can cause severe lateral hip pain, limp, and abnormal gait. A variety of open and endoscopic techniques to treat glut abductors hip tears have been described. The use of scaffolds, such as acellular human dermal allograft, to augment tendon repair, already has been successfully reported in rotator cuff repairs of the shoulder. Still, the use of acellular human dermal allograft in the hip has been limited. However, there are some clinical scenarios in which augmentation of abductors hip tendon repair with scaffold is indicated. Chronic or massive gluteus tears or revision cases may benefit from augmentation with a scaffold. The purpose of this technical note and accompanying video is to describe our indications, pearls, and pitfalls of repair of moderate to severe gluteus tears via a minimally invasive technique augmented with acellular human dermal allograft.
