A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. Bursitis is inflammation and swelling of the bursa. Trochanteric and Iliopsoas are the two most common bursitis found in the hip/groin regions. Trochanteric bursitis is a result of inflammation of the bursa located between the point of the hip and the overlying gluteal muscles. Iliopsoas bursitis is inflammation of the bursa located at the attachment of the iliopsoas (hip flexor) onto the hip bone. These bursitis are a result of friction on the bursa due to tight gluteal/hip flexor muscles and poor pelvic biomechanics. These factors cause increase wear and tear on these bursas which develop into bursal thickening and inflammation. Activities such as stair climbing, running, crossing legs, kicking, walking, getting in and out of the car are all common aggravating factors for these injuries.
Signs and Symptoms:
- Generally produces a swelling and pain over the involved bursa which may become sharp pain with movements of the hip.
- Pain may radiate to the outside of the hip (trochanteric) or fornt of the hip (iliopsoas).
- Night pain, especially when lying on the affected hip.
- Altered gait pattern due to tight muscles around inflamed bursa.
