How To Inject a Trochanteric Bursa
Introduction
Trochanteric bursal injection is the process of puncturing a bursal sac and/or the area around it with a needle and injecting anesthetics, often with corticosteroids, to help treat greater trochanteric pain syndrome. Isolated trochanteric bursitis is now believed to occur rarely, and lateral hip pain is more often referred to as greater trochanteric pain syndrome, which most often originates from gluteal medius and minimus tendinopathy, sometimes with an associated bursitis. However, the injection technique (aimed at the point of maximal tenderness) is the same for both isolated trochanteric bursitis and greater trochanteric pain syndrome. The deep bursae (trochanteric, subacromial, or anserine) lie between bone and overlying tendons. Bursitis of a deep bursa seldom manifests with visible swelling or erythema. (See also Bursitis .)
