Gluteus Medius and Minimus Tears Open Repair/Reconstruction
摘要
The pathology of abductor tendons is the most common cause of greater trochanteric pain syndrome (GTPS). Around 50% of patients with GTPS show gluteal tendinosis or ruptures. The incidence of GTPS increases with age. The primary symptom of abductor tendon issues is pain in the lateral thigh. A detailed clinical examination should be undertaken, including assessment of muscle strength, neurological status, lumbar spine and hip conditions and the integrity of any existing prosthetic joint. Magnetic resonance imaging is the gold standard for evaluating abductor muscle and tendon pathology. Treatment for GTPS usually begins with conservative methods, using various modalities. Surgery is mainly considered for full or partial gluteal tendon ruptures that do not respond to at least 3 months of conservative treatment and cause ongoing pain and disability. Patients planned for surgical repair of gluteal tendon tears must undergo comprehensive preoperative assessment. Management of acute or chronic degenerative abductor tendon tears without muscle degeneration is generally performed using non-augmented repair, employing bone tunnels or suture anchors, via open or arthroscopic procedures. Chronic, irreparable, end-stage abductor tears are treated with augmented repair using synthetic grafts, allografts or muscle transfer reconstruction.
