Hip impingement
There are several different impingement syndromes of and around the hip, which are all characterized by a painful reduction of motion in the hip joint.
- femoroacetabular impingement (FAI)
- ischiofemoral impingement
- anterior inferior iliac spine impingement
- greater trochanteric-pelvic impingement
Femoroacetabular impingement is intraarticular, the other hip impingement syndromes are external forms of impingement.
