This is a variation of bony structure within one or both of the bones forming the hip joint. This extra bone growth can lead to the bones rubbing against each other during movement, causing friction which can damage the joint and causing pain to develop.  FAI affects approximately 20% of the population and is thought to have a genetic predisposition. It can develop during the rapid growth stages during adolescence.  Not all people with FAI experience pain, people who are active (athletes, active people) are more inclined to experience pain from FAI.  Athletes and active people tend to do more vigorous movement causing the likelihood of damage to the labrum and cartilage within the joint.  


  • Pain
  • Stiffness or limping.

Movements which can trigger the pain

  • Twisting, turning, squatting, crossing your legs, sleeping with your leg rolled in.

How can Myotherapy help? 

Once we have identified an individual has FAI, we will look at the activities they are currently involved in. Often a change in activity and/or movement patterns can reduce the likelihood of ongoing impingement, as can the volume or load of such activities.  Movements that incorporate flexion, internal rotation and adduction should be avoided.  These actions are usually performed when crossing your legs or hiking one hip.  Soft tissue therapy can help reduce the tightness in surrounding muscles and specific strengthening exercises are often required to increase your movement in the area and to help support the joint.
