Femoral Acetabular Impingement (FAI)

Femoral Acetabular Impingement (FAI) is a condition that occurs with excessive friction in the hip joint.  FAI is a result of the ball (femoral head) and socket (acetabulum) rubbing abnormally, resulting in damage to the hip joint.  Impingement is often described as Cam, Pincer, or a combination of the two. These descriptions simply refer to the shape and alignment of the femoral head or the acetabulum.

Cause of injury

Some individuals are predisposed to FAI due to the anatomy of the hip joint. FAI is common in high-level athletes, but can also occur in less active individuals.

Signs and Symptoms

Common signs and symptoms of FAI include pain, swelling, and decreased range of motion in the hip. Certain types of movements, such as hip flexion or internal rotation, may result in more pain than others.

Diagnosis

The diagnosis of FAI involves a complete examination of the hip joint by a physician or physical therapist. Additional testing, such as an X-ray or MRI, may be necessary for proper diagnosis.

Treatment

Some individuals will experience some relief after rest, activity modification, and/or physical therapy. Depending on the severity, treatment may involve surgical correction of the underlying anatomical impingement. Regardless of initial treatment, a comprehensive rehabilitation program will ensure muscle imbalances are corrected and a safe return to sports and activities of daily living as quickly as possible.
