1

Order of neurovasculature in femoral triangle

vein, artery, nerve (medial to lateral)

2

location of cricothyroid membrane (for cricothyroidotomy if someone is choking)

superior to cricoid cartilage inferior to thyroid cartilage (vignettes 22)

3

paraesophageal hernia

Fundus protrudes into thoracic cavity. GEJ remains fixed below diagram unlike in sliding hiatal hernia.

4

Femoral nerve palsy: 1) common scenario 2) dysfunction

1) Pelvic fracture
2) weakness in right leg and lack of sensation in anterior area of thigh + weakness with extension of right knee + weak hip flexion

5

klumpke vs erb palsy

klumpke is an abduction injury; Erb palsy is an adduction injury

6

Jugular foramen (Vernet) syndrome

lesion to jugular foramen, thus CN 9, 10, 11 affected

7

Jugular foramen (Vernet) syndrome presentation

dysphagia + hoarseness + dysarthria + loss of gag reflex on ipsilateral side + deviation of uvula toward normal side + atrophy of sternocleidomastoid muscle and trapezius.

8

unhappy triad

ACL + MCL + medial meniscus

9

compartment syndrome presentation

Persistent leg pain + swollen, tense, and warm region + decreased anterior tibial pulse.

10

causes of compartment syndrome

crush injury + fracture + chronic vigorous exercise

11

FDS vs. FDP

- FDS wraps around PIP.
- FDP goes all the way to the end and flexes wrist + MCP + interphalangeal joints.

12

ACL location

lateral femoral condyle --> anterior tibia.

13

PCL location

medial femoral condyle --> posterior tibia.

14

Lachman test

Tests for ACL injury, at 30 degree angle

15

valgus/varus

lateral force/medial force

16

McMurray test

1) pain, "popping" on external rotation --> medial meniscal tear.
2) pain, "popping" on internal rotation --> lateral meniscal tear.

17

Baker cyst

Popliteal fluid collection in gastrocnemius-semimembranous bursa, commonly communicating with synovial space and related to chronic joint disease.

18

most common rotator cuff injury?

supraspinatus

19

test for supraspinatus tear?

"empty/full can" test.

20

infranspinatus innervation

suprascapular nerve

21

Most common pitching injury

infraspinatus

22

teres minor innervation

axillary

23

subscapularis innervation

upper and lower subscapular nerves

24

SITS muscle innervated by

C5-C6

25

bone palpated in anatomic snuff box

scaphoid

26

lunate dislocation

Can cause carpal tunnel syndrome

27

damage to hook of hamate

ulnar nerve injury (common with fall on outstretched hand).

28

axillary innervation

C5-C6

29

musculocutaneous innervation

C5-C7

30

loss of supination suggests...

musculocutaneous damage
