OINAS
Innervation of glute max
Inferior gluteal nerve
Roll and glide for NWB knee flexion

What motions does the iliofemoral ligament primarily restrict?
Hip ER and extension
When palpating your patient's ankle, you note bony tenderness at the lateral malleolus. What's your next right move?
Refer pt for x-ray
Position of maximal congruency of the hip joint.
Quadruped
All muscle actions of the gluteus medius
hip abduction
anterior fibers--> IR
posterior fibers--> ER
Roll and glide for NWB hip IR
anterior roll, posterior glide
What does the medial meniscus have attachments to?
MCL, medial joint capsule (doesn't move as much)
Your patient has a high ankle sprain. What AROM testing will be painful?
Ankle DF and eversion
Compensation if someone has femoral retroversion.
Toe-out
Muscles innervated by the deep peroneal nerve
Tib ant, EHL/B, EDL/B, peroneus tertius
Roll and glide for NWB ankle DF

Where is the articular cartilage the thickest on the femoral head?
Superior and posterior
Your patient has medial knee pain and laxity with valgus stress testing at both 0 and 30 degrees. What structure(s) are likely involved?
MCL
Possibly ACL and PCL too
What muscles' primary function is hip IR?
None!
Insertions of peroneus longus AND brevis
base of 1st met
styloid process of 5th met
Roll and glide for WB knee extension
Role of the ACL?
Anterior roll, posterior glide
ACL pulls the femoral condyles posteriorly while the femur rolls anteriorly (i.e. helps with the glide)
What motion does the CFL resist?
Straight inversion

biceps fem LH, semiten/mem, adductor magnus hamstring part
inferior gemellus, quad fem
Describe iliosacral anterior rotation in terms of the direction the ASIS and PSIS move
ASIS moves inferior, PSIS moves superior
What motions do the iliolumbar, sacrotuberous and sacrospinous ligaments restrict?
posterior rotation of the innonimate and nutation of the sacrum
What PROM will be painful for your patient with an ATFL sprain?
PF and INV
