The trochanteric bursa is a fluid-filled sac that functions to reduce friction between the iliotibial (IT) band and the greater trochanter of the femur. This bursa can become inflamed, a condition known as bursitis, commonly caused by a tight IT band.
Patients complain of pain on the side of the hip and thigh, as well as an inability to sleep on the affected side. This condition is typically exacerbated with repetitive flexion of the hip, as in running. Treatment of trochanteric bursitis includes NSAIDs (non-steroidal anti-inflammatories, such as ibuprofen, Advil, Aleve, etc.), activity modifications, and a short course of physical therapy involving ultrasound, ice application, and IT band stretching exercises.
If symptoms do not resolve, a steroid injection may be performed to calm the inflammation in the bursa. An arthroscopic trochanteric bursectomy may be indicated if conservative care fails.
