FAI Hip Impingement (Femoro-acetabular Impingement)

FAI Hip Impingement Awareness facts - It is estimated that approximately 15% of the young, adult population have hip impingement, so who do you know that might have it?
Hip impingement causes painful labral tears within the hip socket.
Hip FAI symptoms are misleading to the average medical professional, as FAI hip impingement pain frequently presents as low back pain and interesting only 10% of back pain is ever clinically diagnosed and cured... Which begs the question what percentage is actually caused by hip FAI or hip impingement, as its otherwise known.
The more active you are, the more likely you are to trigger hip impingement symptoms, so busy mums and gym bunnies beware... but at least you're in good company as many premiere league football players have also suffered FAI hip pain.
Hip impingement is diagnosed through x-ray and labral tears are diagnosed through MRI arthograms - but both need to be read by hip consultants specifically trained in FAI hip impingement.
There are 60,000 hip replacements every year in the UK and it now appears that FAI hip impingement, over the years, could be the leading cause of hip osteoarthritis. A silent epidemic.
Hip arthroscopy can reduce the hip impingement and reattach the torn labrum to the hip socket. This surgery can eliminate the pain and disability caused by FAI hip impingement and divert the need for hip replacement in later life.

Hi I'm Louisa Weeks, from the UK and my FAI Hip impingement story began in September 2003 with low back pain, pain on sitting and after a couple of years, groin pain arrived. I was written off as having a bad back, despite regularly asking if it could be a hip pain issue.. 'No you're too young', they said, not true, you can be any age to develop FAI hip pain and mostly hip impingement effects the young and athletic.
By 2009 and I had no sitting tolerance and little ability to walk for more than 10 mins. After seeing easily 20 experts over 6 years, I finally chanced upon a fantastic physio Louise Grant at Physiocure, Esporta in Leeds, Louise Grant suspected a hip labral tear caused by FAI hip impingement. Consequently I met my consultant and had several x-rays and an MRI arthogram and the evidence is there to see - bi lateral (both hips) femoral acetabular hip impingement, pincer type and this had also caused a labral tear within the hip socket.
I had a hip arthroscopy in July 2009 to reduce the pincer part of my hip socket and re-attach the torn labrum to the socket. This was done by UK FAI hip impingement expert Professor Ernest Schilders. I am 2 years post op with mixed results. However FAI hip impingement is currently in its infancy, though advancing daily and I feel sure I will be fixed. Treatment for femoral acetabular impingement (FAI) of the hip has advanced, even since my surgery. The knowledge, technology and experience is progressing daily, so I do believe my FAI hips will be fixed and if that is true, then so can yours...  (Since writing this page 2 years ago I have had further surgery with a brilliant surgeon called Paul Jairaj from London Sports orthopaedics.  Significantly better recovery and outcome than my first surgery. Paul Jairaj re-did my right hip and found scar tissue and a large missed cam, left by previous surgeon and then operated on my left. So far and touch wood I am doing well, though have been warned that I now have grade 3 arthritis in my right hip, so I suspect at some point in my life to need a total hip replacement.)
