Abstract
Purpose: FAI has been defined as a dynamic cause of hip arthritis, mostly present in young adults without any other cause of pain in the hip joints. It is typically present in young soccer players, or ice hockey players, or patients with hypermobile joints.
Methods: X-ray diagnosis with subsequent therapy - Joint Preserving Surgery - is essential for FAI. X-ray diagnosis is very important to specify alpha angle - the diagnostic angle for the FAI.
Over 65deg. is specific for FAI cam type and usually needs operative therapy. The offset ratio - OR is not as specific as alpha angle is, and it could be decreased in any other necrosis or other hip affection in the joint.
Results: Operative therapy is essential for FAI as it is a dynamic cause of arthritis - which is caused only during specific movements of the hip. Basic operation from Joint Preserving Surgery technique is open dislocation and modulation of the hip through Ganz approach.
This seems to be very safe procedure for the hip motion, though we still couldn't say how this prevents or postpone final arthritis of the hip. Conclusion: The aim of this study is to present basic diagnosis and therapy in FAI patients.
