Flashcards in upper extremity squirm Deck (28):
1

Classification of clavicle fractures that are lateral third?

Allman
Group 2 type 2 is operative
1. lateral to conoid
2a is medial to conoid and trapezoid so displaced
2b is torn conoid
3 is intraarticular into joint and table. arthritis risk

2

Type IV and V A/c separation

4 is posterior and into trap.. V is more than 100% with displacement, skin tenting
VI is conjoined tendon

3

Compartment syndrome sign for scapula?

Comolli sign

4

Corocoid classifcaion

1 is proximal to cozrococlavicular ligament, 2 is TIP

5

Glenoid classification

Ideberg
1a anterior rim, 1b posterior rim
2 is inferior/lateral
3 is superior
4 is medial exit fracture
5 is mix
6 is comminuted

6

OR for glenoid when?

25% or more involvement or 5 MM step off. CONSIDER 3d econ

7

When do you operate on scapula neck?

40 degrees translated

8

Acromion fracture classification

1 nondisplaced
2 opening of subacromial space
3 closure of space. THREE IS OPERATIVE

9

Classification of scapulothoracic dissassocation

Mild medium hot. 1 cm neuro intact. 2 a vascular 2 b neuro issue 3 is both neuromuscular out

10

HAGL? Bankhart? Hillsachs? Who gets rotator cuff tear? What is hillsachs view

Humeral avulsion of glenohumeral ligaments.

labral tear, or fracture of glenoid if bony, hillsachs is humeral head fracture.

Hilsachs view is internal rotation to see posteriolateral cortex

11

blood supply humeral head

Used to say anterior circumflex to arcuate, but now say posterior humeral circumflex contributes a lot

12

parts of humerus definition

45 degree angle or 1 cm separation unless greater tuberosity and it is 5 mm.

Lesser tuberosity: assume posterior dislocation until proven otherwise.

13

Proximal humerus malunion classification

2 classifications

Beredjiklian
1. tuberosity off 1 cm
articular surface incongruent
3 articular surface malalignmed

boileau
1 necrosis or impaction
2 chronic dislocation
3 surgical neck nonunion
4 malunion of tuberosity is SEVERE

14

Where is radial nerve?

14 cm from lateral epicondyle, 20 from medial

15

Acceptable humerus shaft allignment

20 degrees ap, 30 varus/valgus and 3 cm shortening

Nonunion risk increaesed in proximal third

16

Distal humerus intercondylar fracture classification

Risenburg

1 non displaced
II slight displacement without rotation
III rotated
IV severe comminution

Tx is ORIF or Bag of Bones

17

AO distal humerus classiation

A extreaarticular
B single column
C both column

18

What is concern of Jupiter H type?

Trochlea at risk of AVN (Jupiter is 2 column distal humerus fractures)

19

Olecrenon schatzker

transverse
transverse with dip
oblique
comminuted
oblique distal
Comminuted?

20

Radial head classification

Mason - 4 types
Nondislaced
angulatedmight block
III comminuted and blocked
4 with a dislocation

fun fact LCL injured with 80% of them

21

OR for radial head?

2 mm displaced of 25% of articular surface

22

Insertion of mcl most important bundle?

Anterior bundle on sublime tubercle (Anterior medial facet of coronoid

23

LUCL insertion

tends to avuse off of lateral epicondyle. It inserts on supinator crest

24

Monteggia classification

Bado:
1 anterior in kids commonly
2 posterior dislocato (subclassifications from proximal to far).
2 a is coronoid level. B is metaphysical junction. C is distal coronoid, D is distal half of ulna
3 is laterally
4 is both bone FF with radial head dislocation

25

Nerve with monteggia?

PIN

26

5 ligaments of IOM?

Central band is key. Accessory, distal oblique, proximal oblique, dorsal oblique accessory cord

27

When can you cast ulna?

Distal 2/3. 50% overlap and less than 10% displacement

28

DRUJ suspicion of

5 mm shortening, ulnar styloid avulsion, subluxation on XR or wide AP space on AP
