Endoscopic treatment of calcific tendinitis of gluteus medius and minimus.

Calcific tendinitis results from deposition of calcium hydroxyapatite crystals in periarticular muscle attachments. Although involvement of tendons around the hip is not uncommon, gluteus medius and minimus tendons are rarely affected. We present endoscopic treatment of calcific tendonitis of gluteus medius and minimus and associated trochanteric bursitis in a patient with 2-year history of lateral hip pain. This is the first reported case treated using an endoscopic approach, which is effective and minimally invasive.
