Hip surgery for femoroacetabular impingement syndrome (FAI)
Femoroacetabular impingement (FAI) results from abnormal morphology of the acetabulum and femoral head/neck resulting in abnormal contact between the proximal femur and acetabulum during the end range of hip motion, particularly flexion and internal rotation. There are two types of FAI: cam impingement (non-spherical femoral head or abnormality at the head-neck junction) and pincer impingement (deep or retroverted acetabulum resulting in over coverage of the femoral head).
Status: Public comment open
Why is FAI being reviewed?
Proponents believe that surgical correction of the impinging deformities will alleviate the symptoms and retard the progression of OA degeneration. However, significant questions remain about the safety, efficacy and effectiveness, and cost effectiveness of hip surgery for FAI.
Primary criteria ranking
