Flashcards in UE Deck (51):

2

Reverse Barton Fx

volar margin of the distal radius best viewed laterally

3

Hutchinson Fx

4

Smith Fx

Large fx of the distal radius that displaces volarly
MOI fall on back of hand or direct blow to dorsum of hand

5

Galeazzi Fx

Fx of distal 1/3 of radius with proximal end displaced dorsally
MOI FOOSH or blow to dorsolateral wrist

6

Best view of scaphoid bone

PA with ulnar deviation
MOI FOOSH

7

Best view of pisiform and pisotriquetral joint

Supinated oblique

8

Best view of triquetral bone and radial styloid

Pronated oblique

9

Best view of hook of hammate, pisiform, and volar aspect of trapezium

Carpel tunnel view (full wrist extension)

10

Bennet Fx

Fx of proximal end of the 1st metacarpal

11

Boxers Fx

Fx of metacarpal neck (typically 5th) with volar angulation of distal fragment

12

Gamekeepers Thumb

Fx of base of proximal phalanx

13

Stener Lesion

Ruptured end of ulnar collateral ligament displaced superficially to the adductor pollicis aponeurosis

14

Hulten Variance (ulnar variance)

radial styloid process normally exceeds the length of articular end of ulna by 9-12 mm
Negative variance ulna is more proximal (more than 12 mm)
Positive variance ulna is displaced distally and has less ulnar variance

15

Radial angle

ulnar slant 15-25 degrees

16

Palmar Inclination

Volar tilt of the articular surface of radius 10-25 degrees

17

TFCC

Triangular Fibrocartilage Complex
Triangular fibrocartilage
Radioulnar ligament
Ulnocarpal ligament
Extensor Carpi Ulnaris tendon sheath
Meniscus homologue

18

Normal Elbow carrying angle

approx 15 degrees

19

CRITOE

Capitellum
Radial Head
Internal (Medial) Epicondyle
Trochlea
Olecranon
External (Lateral) Epicondyle

If you see only 3 fragments should be the first 3 on the list otherwise (they disappear with External epicondyle first)

20

Elbow Lateral View

Best view for olecranon process, anterior radial head, humeroradial joint
Disad- poor view of posterior radial head and coronoid process

21

Radial head Capitellum view

Radial head visible free of coranoid process, good view of capitellum, hueroradial and humeroulnar

22

What position do most elbow fractures occur in?

extension

23

Radial head fx Mason System

Type 1 - Undisplaced
Type 2 - Displaced
Type 3 - Comminuted (multiple fragments)
Type 4 - Fx with dislocation
MOI FOOSH

24

Osteochondritis Dissecans

Panner Disease valgus strain of elbow leads to fllattening of capitellum

25

Radial head articulates with what part of the humerus?

Capitellum

26

Ulnar coronoid process articulates with what part of the humerus?

Trochlea

27

Monteggia Fx

Fx of ulna and dislocation of radius
MOI: force pronating during fall or direct blow to posterior ulna

28

Bado Classification

Type 1 Distal Ulna displaced posteriorly
Type 2 Distal Ulna displaced anteriorly
Type 3 Distal ulna displaced laterally
