Femoroacetabular impingement symptoms
There are three types of FAI: pincer, cam, and combined. A pincer impingement occurs when bone spurs develop around the rim of the acetabulum. A cam impingement, on the other hand, occurs when imperfections in the femoral head catch on the side of the acetabulum. A combined impingement occurs when bone spurs exist on both the ball and socket.
Patients with FAI may experience quite painful and severe symptoms, or no symptoms at all. In the event that symptoms do arise, they’re likely to take the form of pain or aching in the inner hip or groin areas, especially after prolonged sitting or walking. Patients may also experience a locking or clicking sensation in the hip joint.
The most common symptoms of femoroacetabular impingement include:
- Pain in the hip joint
- A locking, clicking sensation in the hip joint
- Pain after prolonged sitting or walking
- Low back pain
