Study Notes

Reduced hip motion may indicate disease or trauma.
Limited hip motion can impact daily activities.
Two terms describe hip kinematics: femoral-on-pelvic and pelvic-on-femoral.
Range of motion is reported using the anatomic position as the reference point.
Each plane of motion is associated with a unique axis of rotation.
Internal and external rotation occur around a longitudinal axis of rotation.
The amount of hip flexion varies with knee position and hamstring muscle flexibility.
Hip abduction is limited by the pubofemoral ligament and adductor muscles.
Hip adduction may be limited by passive tension in hip abductor muscles and the iliotibial band.
Internal and external rotation are particularly variable among subjects.
