Femoroacetabular Impingement (FAI) is one of the most common conditions seen in the hip. It occurs when extra bone known as bone spurs grow on one or both of the bones that form the hip joint resulting in friction when the bones rub together during movement. This friction can cause damage to the joint, resulting in pain. FAI is caused by the incorrect formation of the hip bones during childhood. When this deformity occurs, little can be done to prevent FAI, although excessive activity in sports or exercise may cause those with the deformity to experience the pain earlier. The most common symptoms of FAI are pain, stiffness, and limping, with pain often centered on the groin area.
Surgery to correct the impingement can prevent future damage and treat some of the symptoms. However, severe damage, may not be resolved by surgery. As surgical techniques continue to advance, doctors will likely recommend earlier surgery for FAI to prevent future damage to the joint.
