L5 and S1
what are the ADductors of the leg
ADductors longus, brevis, magnus, obturator externus and gracilis mm
what innervates ADductor longus
L2L3L4
what may happen in cases of persistent groin pulls
inferior pubic symphysis shear
What are the internal rotators of the hip
tensor fascia lata, gluteus minimus and medius
what innervates gluteus minimus
L5S1
what are the external rotators of the hip
obturators, gemelli, quadratus femoris, gluteus maximus, sartorius and piriformis
what innervates piriformis
S1 and S2
what mm can cause a decrease in hip internal rotation and irritate sciatic nerve
piriformis
what is the function of the acetabular labrum
helps maintain hip stability and provides proprioceptive information regarding hip motion
in fractures or degenerative joint diseases what motion goes first
internal rotation
when the knee is fully extended what position is it in
passively locks because the femoral condyles medial rotate
what portion of the menisci is less likely to heal and why
inner because it is avascular
what can joint locking of the knee be indicative of
severe meniscal tear
what is the terrible triat or O’Donoghues triad
injury to ACL, MCL and medial meniscus
what innervates the biceps femoris m

T10-L3
ehat is the return to work/play/sports criteria
full painless ROM, strength at least 90%
able to tolerate without increasing symptoms
tightness in ADductor longus can lead to what in the pubic area
