1

femoral nerve injury most common cause

abdominal pr pelvic surgery

2

inguinal ligament what movement is spared
what movement is affected?

Spared :
Affected:
Sensation: anterior though, medal leg

3

longest branch of femoral nerve

saphenous nerve

4

saphenous neuropathy

medial knee pain
abnormal sensation in medial aspect of leg and foot

Saphenous neuropathy - pure sensory syndrome with no medial

5

what muscle does superior gluteal nerve innervate

Flute med , min and TFL

6

Commonly injured in conjunction with femoral nerve

obturator
- compression from fracture or hernia

7

obturator neuropathy injured

Wide bassed gait circumduct

8

entrapment of sciatic nerve

piriformis
injection
hip trauma
hip replacement
pelvic fracture
hematoma
infection
tumour
radiation
intramuscular injection

9

peroneal division of sciatic nerve above fibular next innervates

biceps femurs short head

10

tibial innervated

long head, semi mem , semi tendinousus , adductor magnus ( with obturator)

11

Tarsal tunnel syndrome

flexor retinaculum compresses tibial nerve , rare

12

what contents of the tarsal tunnel

tibial nerve
FHL
FD
tibitals posteiro
Tibial N , posterior tibial artery , posterior artery

Tom dick and very nervous Harry

13

anterior tarsal tunnel syndrome

compression of the terminal deep perineal nerve at the talonavicular joint deep to EHL tendon or superior and extensor retinaculum

Trauma , tight shoes, boney abnormalities, res cavus

Weakness EDB
numbness 1st and 2nd foot

14

total hip replacement - what is the most likely nerve injured and what would be second most likely

Sciatic - number one
Femoral second

15

walking slap slap slap sound
what are you worried about?
what gait does she have?

foot drop
- steppage gait

16

weakness of ankle dorsiflexors and ankle evverter s

common perineal neuropathy at the fibular head

17

Ddx

L4,5
polyneuropathy
lumbosacral plecopathy
sciatic nerve palsy
MND
intraspinal

18

9 levels of NS

Cerebrum,
BG
Cerebellum
brainstem
Cord
plexus
motor nerve
NMJ
Muscle

19

treatment of fibular nerve

avoid further pressure or injury to nerve
+/- AFP
Occasional surgical release

20

what do you call foot drop if its the LMN cause

spasticity

21

if you can't get a motor responds at EDB and what to assess fibular motor response what other muscle can you use?

tibitalis anterior
- also innervated by perineal nerve ( deep
Patient with foot drop it is weakness of TA that accounts for clinical deficit

22

Common nerve injury in Lower extremity

Fibular nerve injury

23

morton's neuroma

irritation of the interdigital nerve at the MTP joint of foot
3rd and 4th digit

test: squeeze and put pressure b/w wedge

24

Trendelnburg gait - nerve injury

superior gluteal nerve

25

pain on left foot - where does the cane go?

right hand - so that the ground reaction force goes toward the good leg and away from bad leg

26

piriformis pain DDX

trochanteric bursitis
L5 ridiculopathy
sciatica
inflammatory arthritis
fibromyalgia
CRPS


27

how do you stretch the piriformis muscle

figure 8 pose

28

strawberry pickers palsy

common fibular palsy
