Flashcards in Lecture 2: Upper limb bones and joints Deck (12):
1

Bones in the upper extremity

30 bones

2

Lesser tubercle

Anterior side

3

Greater tubericle

Extends laterally

4

3 of the 4 muscles of the rotator cuff

Attach to the greater tubercle

5

Surgical neck

fracture just below the head needs a pin or wire to be inserted
Fracture here compromises the deltoid. SITS muscles will cause the limb to drop

6

Movement of the arm

Foward -> deltoid and pect
Backward -> deltoid and lats

7

Epicondyles

5 muscles attach to both lateral to medial

8

landing on hands with elbow extended

force goes to -> carpal bones -> radius -> interossetus membbrane -> ulna -> humerus -> shoulder -> scapula -> Clavicle = SNAP

9

Fall on hands with elbow bent

Force -> hands -> carpal bones -> radius = SNAP
2 inches beyond the wrist, sometimes the ulna at the same location = colle's fracture

10

Little leaguer elbow

16 yr or less, injured the grwoth plate of epipcondyle medial collateral ligmanet, stretching or tearing it

11

Pitcher's elbow

older than 16,
Tear or stretch the medial collateral ligament
You get tommy John surgery (Pitcher)
Tissue from palm is put in the elbow

12

Wrist and distal radius fractures

most common fractures in indv 50 yrs of age or older
