Posterior to joint
The pelvic band on an HKAFO should be located
Midway b/w the iliac crest and the greater trochanter of the femur
A metal single axis (free motion) orthotic hep joint will control all the following motions at the hip except:
Extension:
Will control abduction, adduction, in and ex rotation
An infant with bilateral dislocated hips is usually fitted with an ox that will hold hips in:
Flexion and abduction

Milwaukee CTLSO
WHEN casting for the Milwaukee CTLSO, the patients pelvis should be in what position?
