Lower body

Question 1

Lateral femoral cutaneous N

Origin
Muscle
Commonly entraped

Answer 1

2nd and 3rd Lumbar nerves

Passes through the posts muscle (2nd and 3rd Lumbar nerves combine in the muscles)

commonly entrapped in the lateral aspect of the inguinal ligament

ONLY SENSORY

Question 2

arises from the 3rd and 2nd lumbar nerves, formed in the Psoas muscles and is most commonly impinged at the lateral aspect of the ilioinguinal ligament

Answer 2

Lateral femoral cutaneous N-meralgia paresthetica

Question 3

Meralgia paresthetica vs Lumbar nerve roots

Answer 3

Lateral femoral cutaneous N is solely sensory so zero mmt findings, usually better when seated and worse when standing, aggravated by hip extension

Lumbar nerve roots 1&2: weak quads and patella reflex

Question 4

False Meralgia paresthetica

Answer 4

entrapment of superior gluteal Nerve

innervates medius, minimus and TFL

Question 5

Meralgia paresthetica vs Lumbar nerve root 2 and 3

Answer 5

Lateral femora cutaneous N- Sensory only
Tender latereal inguinal ligament that deep palpation makes pain worse

2nd 3rd Lumbar- diminished patellar reflex and Quadracep strength

Question 6

False Meralgia Paresthetica

Answer 6

entrapment of the superior gluteal N

Question 7

cutaneous innervations for which nerves?

Answer 7

Question 8

Glute max is vulnerable in piriformis syndrome because…

Answer 8

Inferior gluteal nerve differentiates below the piriformis muscle making it vulnerable to hyperotonicity sparing glute medius and minimus innervated by superior gluteal nerve

Question 9

Piriformis syndrome management

Answer 9
