Pincer impingement is a condition that occurs in the hip joint, where the acetabulum (the socket of the hip) is overly deep or has an abnormal shape. This can lead to the femoral head (the ball of the hip) being pinched during certain movements, causing pain and limited range of motion. This condition is often seen in athletes and can result from repetitive activities that involve hip flexion and rotation. Treatment options may include physical therapy, anti-inflammatory medications, or, in severe cases, surgery to reshape the acetabulum and relieve the impingement.
