Implant survival at four years for hemiarthroplasty and total shoulder arthroplasty in the treatment of atraumatic avascular necrosis of the humeral head.

Aims: Hemiarthroplasty (HA) and total shoulder arthroplasty (TSA) are often the preferred forms of treatment for patients with atraumatic avascular necrosis of the humeral head when conservative treatment fails. Little has been reported about the survival of HA and TSA for this indication. The aim of this study was to investigate the differences in revision rates between HA and TSA in these patients, to determine whether one of these implants has a superior survival and may be a better choice in the treatment of this condition.

Endoscopic bursectomy and iliotibial tract release as a treatment for refractory greater trochanteric pain syndrome: a new endoscopic approach with early results.

Greater trochanteric pain syndrome (GTPS) is associated with excessive tension between the iliotibial band (ITB) and the greater trochanter. Several endoscopic procedures have been reported, but in most cases the endoscopic approach only consists of a bursectomy. The ITB and fascia lata act as a lateral tension band to resist tensile strains on the concave aspect of the femur and are often implicated as the source of GTPS.
