What is Femoroacetabular Impingement (FAI)?

The femoral head and pelvic acetabulum are the two bones that form the hip joint. Smooth articular cartilage covers the femoral head and a rim of cartilage called the hip labrum surrounds the outer edge of the acetabulum. These structures help the hip bones move smooth and easy without pain.
Femoroacetabular impingement (FAI) occurs when excess bone or bone spurs on the femoral head and/or acetabulum cause the femur and acetabulum to rub against each other.

Common Causes:

  • Bones that do not form normally during the childhood growing years
  • Athletes

Symptoms of FAI may include:

  • Shooting, stabbing, burning pain
  • Dull aching pain
  • Stiffness
  • Limping

Symptoms are often triggered by or get worse because of twisting, turning, and pivoting movements. An early, accurate FAI diagnosis is important because it helps to treat the condition before it gets worse. Orthopedic Physicians Alaska (OPA) hi specialists use a step-by-step approach to diagnose FAI:

  • A medical history review that includes checking for FAI risk factors like bone growth abnormalities and arthritis is obtained
  • A complete hip examination that includes impingement, strength, and flexibility tests is performed
  • Multiple view x-rays are ordered and analyzed to see how well the hip bones articulate at rest and while standing

Once the severity of FAI is determined and a formal diagnosis is made, a customized treatment plan is created. Treatment focuses on reducing symptoms and improving function as quickly as possible.

Common Treatments:

A combination of nonsurgical treatment options treat mild to moderate FAI:

Nonsteroidal anti-inflammatory medications (NSAIDs)

Decreases inflammation and pain.

Physical Therapy

To stretch, strengthen, and stabilize the hip

Activity Modification

Limits movements that cause symptom flare-ups

FAI that does not respond to nonsurgical treatment, minimally invasive arthroscopic surgery may be recommended treatment option. An OPA specialist carefully removes small pieces of symptom-causing bone and cartilage during an outpatient procedure.
