Description
Bursae are sac-like structures, with an inner synovial membrane, that produces a thin film of synovial fluid. They aid in reducing friction between moving tissues of the body, such as between tendon and bone, ligament and bone, tendons and ligaments, and between muscles.
The bursae of the hip joint include the iliopectineal bursa and the trochanteric bursae of gluteus maximus, medius, and minimus muscles.
Inflammation of the trochanteric bursa can lead to trochanteric bursitis. The main presenting symptom is hip pain, worse at night when lying on the affected side and aggravated when getting up from a chair after being seated for some time, or by repetitive stress such as in prolonged walking and running.
