patient with trauma to lateral leg, only superficial fibular nerve in injured. what can he not do?
cannot evert+ senstaion of dorusm and distal third of anterior leg
patient with charcot marie tooth, he has what type of symptoms?

knee trauma penetrating injury
tibial
just traction like anterior and posterior knee injury
popliteal artery

chronic inflam
great siatic foramen is divided by piriformis. what goes above(1) and what goes below (3)
and which goes into lesser siatic foramen
above is superior gluteal
below is siatic nerve, pudendal and inferior gluteal
