- large abdomen wearing tight restrictive belts

Question 22

lateral femoral cutaneous nerve: paresthetica meralgia

need to differentiate between

Answer 22

L2-3 radiculopathy

femoral neuropathy

Question 23

lateral femoral cutaneous nerve: where does the nerve run?

Answer 23

• through pelvis anteriorly
• angles down at ASIS and passes through inguinal ligament
• moves toward lateral thigh and pierces fascia latae

Question 24

obturator nerve: originates from

Answer 24

L2-4

Question 25

obturator nerve: formed within what structure?

Answer 25

psoas

Question 26

obturator nerve: formed within the psoas, it runs where?

Answer 26

through pelvis to the obturator canal

Question 27

obturator canal: made up of what?

Answer 27

• fibrous membrane from obturator muscles

- obturator groove in pubic bone

Question 28

obturator nerve: where commonly trapped?

Answer 28

obturator canal

Question 29

obturator nerve entrapment: causes

Answer 29

• trauma from pelvic fx

- inflammation from pubic bone/hip surgery

Question 30

obturator nerve entrapment: symptoms

pain location

Answer 30

• groin

- medial thigh/knee

Question 31

obturator nerve entrapment: symptoms

pain with palpation of

Answer 31

inguinal ligament

Question 32

obturator nerve entrapment: symptoms

pain at end range (motions)

Answer 32

• flexion
• extension
• abduction

Question 33

obturator nerve entrapment: symptoms

weakness in what muscle group

Answer 33

adductors

Question 34

obturator nerve entrapment: symptoms

weakness in adductors may lead to (gait)

Answer 34

• circumduction during swing

- Duchenne during stance

Question 35

obturator nerve entrapment: differentiate from these potential pathologies

Answer 35

• L2-4 radiculopathy
• femoral neuropathy
• hip arthritis
• psoas strain

Question 36

obturator nerve entrapment:

differentiating from L2-4 radiculopathy

Answer 36

• L2-3 have similar distribution to obturator nerve, but not as much L4
• pressure over groin doesn’t cause pain in lumbar radiculopathy***
