EVIDENCE-BASED ANSWER: The answer is unclear. The greater trochanteric bursa appears to be the right target, because ultrasoundguided injections of the greater trochanteric bursa improve greater trochanteric pain syndrome (GTPS) more than ultrasound-guided injection of the subgluteus medius bursa (SOR: C, case series). Blind corticosteroid injections of the greater trochanter result in improvement at 3 months but not at 12 months (SOR: B, single RCT). However, fluoroscopy-guided and blind injections of the trochanteric bursa have equivalent outcomes at 1 and 3 months (SOR: B, single RCT).
