Femoral Acetabular Impingement Syndrome

Femoral Acetabular Impingement Syndrome (FAIS) is a musculoskeletal disorder that involves the hip joint. It occurs when the ball-and-socket joint of the hip becomes impaired due to mechanical abrasion of the femur against the acetabulum, resulting in cartilage damage and bone deformity.

FAI has been increasingly recognized as a major cause of hip pain in adolescents and young adults.

What Is Hip Impingement Syndrome

Femoroacetabular impingement syndrome (FAIS) is a condition that affects the hip joint and is becoming increasingly common in younger adults. It is estimated that up to 20% of individuals between 18 and 40 years old may suffer from it. FAIS occurs when extra bone or soft tissue develops around the hip joint, resulting in a narrowing of the space around it and leading to pain during movement. The symptoms of hip impingement syndrome vary depending on the severity of the condition but can include:

  • Groin pain
  • Difficulty walking
  • Clicking or grinding noises around the hip joint
  • Reduced range of motion in the hip joint
  • Difficulty with activities such as running and jumping

Why Do You Have Hip Impingement Syndrome?

Femoral acetabular impingement (FAI) is a common hip condition caused by added stress on the passive structures of the hip joint. The passive structures in the hip joint, such as the bones and cartilage, are not actively controlled and are susceptible to damage from excessive force.

In contrast, active structures, such as muscles, are responsible for stability and an ideal movement pattern. When the active structures responsible for stability are compromised, the body relies more on the passive structures, leading to added stress on the hip bone (the acetabulum) and leg bone (the femur).

Over time, repetitive forces can cause the body to lay down more bone in response to this stress. This new development of bony tissue called a "CAM or Pincer" lesion, can decrease the space in the hip joint, leading to FAI. If left untreated, FAI can cause pain, decreased mobility, and other complications.

Treatment Method For Hip Impingement

Denner Chiropractic & Performance | Charlotte, North Carolina

Effective treatment for femoral acetabulum impingement (FAI) begins with a trial of conservative care. This typically involves

With early detection and intervention, rehabilitation can be an effective approach to FAI management. At Denner Chiropractic and Performance, we place great emphasis on DNS rehabilitation as we believe it offers the most powerful results in the rehabilitation world.

DNS provides patients with the tools they need to develop ideal movement patterns during daily activities and sports, leading to reduced stress on passive hip structures. Through DNS rehabilitation, our patients can achieve significant improvements in mobility, stability, and overall quality of life.

Frequently Asked Questions

Femoral Acetabular Impingement (Hip Impingement)

What Are The Signs And Symptoms Of Femoral Acetabular Impingement Syndrome?

  • Pain in the hip joint
  • Difficulty with hip movement
  • Clicking or grinding sensations when attempting to move the hip
  • Reduced range of motion of the affected hip joint (Especially true when the hip is placed in maximum internal rotation and flexion) 
  • Tenderness in the groin area
  • Loss of strength in the affected leg

Are There Any Potential Long-Term Complications Associated With Femoral Acetabular Impingement Syndrome?

Over time, FAIS can cause damage to the acetabulum and femur, leading to further joint pain and decreased range of motion. Additionally, if the cartilage becomes too damaged, it may progress to arthritis in the hip joint. Other potential long-term complications include labral tears, increased risk for avascular necrosis of the femoral head, and potential bony deformities due to overgrowth or undergrowth of bone from chronic impingement.

What Kind Of Doctor Should I See If I Think I May Have Femoral Acetabular Impingement Syndrome?

If an individual suspects they may have Femoral Acetabular Impingement Syndrome (FAIS), the most appropriate course of action is to speak to a trained healthcare professional that has proper training in both the evaluation and treatment of FAI. Well-trained sports chiropractors can diagnose and determine if the case requires surgical intervention.
