1) A patient presents with a lesion on L5, S1 and S2 where they converge to form the tibial nerve. Answer the following question on the impact on the walking gait with respect to the gluteal region and thigh.
A) which walking gait functions is this patient no longer able to perform?
B) Why are they able or unable to perform these functions? (in your response, discuss the relevant muscles, nerves, and spinal levels if appropriate)
C) Which walking gait functions are compromised?
D) Why are these functions compromised and not completely unavailable to the patient (in your response, discuss the relevant muscles, nerves, and spinal levels if appropriate)
ASNWER:
A) There are no completely non functional WG functions
B) Trunk extension: functional b/c of G Max (innervated by inferior gluteal nerve so not impacted) & HS pt of Add magnus (innervated by L2, L3, L4 of tibial so again not impacted)
Knee flexion: may or may not be occuring actively. If it is, we still have SH biceps femoris, which is Common fibular nerve, so not impacted
C) Trunk extension & knee flexion

ANSWER

Select the statement(s) that best associate(s) structures to their communicating region:
A) The sural nerve travels through the adductor canal
B) The femoral nerve, and the external iliac artery and vein pass deep to the inguinal ligament
C) The superior gluteal artery and sciatic nerve pass superior to the piriformis muscle to enter the gluteal region
D) The obturator nerve travels with the great saphenous nerve through the adductor canal
E) The femoral nerve, artery and vein pass through the popliteal fossa into the posterior compartment of the leg


ANSWER: B
