Question

what is the arthrokinematics of open chain iliofemoral flexion?
a) anterior roll, posterior glide
b) posterior roll, posterior glide
c) anterior roll, anterior glide
d) posterior roll, anterior glide

Explanation:

Arthrokinematics refers to the movement of joint surfaces. In open - chain iliofemoral flexion (hip flexion), the femoral head (which is the moving part in open - chain) rolls anteriorly on the acetabulum (stationary part). To prevent impingement and allow smooth motion, it glides posteriorly.

Answer:

A. Anterior roll, posterior glide
