A condition of the hip socket where abnormal bone causes tearing of the acetabular labrum and damage to articular cartilage. FAI has been implemented in the development of early onset arthritis of the hip.
Labral tears: The labrum is a rim of cartilage surrounding the periphery of the hip socket (acetabulum). Labral cartilage in the hip is equivalent to meniscal cartilage in the knee and labral cartilage in the shoulder. Tears of the labrum can cause catching and pain in patients.
Greater trochanteric bursitis: Pain and inflammation on the lateral side of the hip (greater trochanteric bursa). Causes can include direct trauma, tightness of the muscles and tendons surrounding the bursa, and wear and tear on the gluteal tendons (gluteus medius and minimus).
Gluteus medius and minimus tears: The gluteus medius and minimus are adductors of the hip (moves the hip laterally away from midline). Through trauma and, more frequently, overuse, these tendons can become frayed and torn. Pain and inflammation from these tears can cause irritation of the greater trochanteric bursa, leading to clinical bursitis of the hip.
