1

Articulations @ Humerulnar joint, humeroradial, proximal radioulnar, and distal radioulnar

humeroulnar- flex/xtend

humeroradial- flex/extend
- sup/pro

prox radioulnar- sup/pro

distal radioulnar- sup/pro

2

Ulnar collateral lig- 3 sections

anterior- medial epicondyle to coronoid process
transverse- medial olecranon to coronoid
posterior-olecranon to medial epi

3

lateral collateral lig
radial collateral lig
annular lig

lateral- lateral epi to tubercle of ulna
radial- lateral epi to annular lig
annular- both ends to coronoid process

4

Median/ulnar/radial nerves what do they supply

median- wrist flexors/extensors

ulnar- 4th/5th digits

radial- digit extensors, thumb, wrist

5

ulnar collateral lig MOI, SS, Test

MOI- valgus force, repetitive throwing

SS- localized pain that worse w/ movement

Test-valgus stress test

6

Osteochondritis Dissecans of Capitulum MOI, SS

MOI- insidious onset, increased valgus loading with throwing

SS- places compressive + sheer forces on capitulum + redial head
- Dull lateral elbow pain
- Xray show loose bone in joint

7

Lateral Epicondylagia MOI, SS, Test

MOI- inflammation or repetitive stress @ lateral epicondyle
- repeated eccentric contractions of wrist
- racket sports

SS- Lateral pain, decreased grip strength

Test- Palpate extensor tendon
- resist wrist extension

8

Media epicondylagia MOI, SS

MOI- Activates involving swift+ powerful snapping of wrist

SS- Point tenderness @ origin of wrist flexors

9

Distal Biceps tendon rupture MOI, SS

MOI- tendon degrades w time, sudden eccentric load

S+S- tenderness, swelling, weakness, tendon not palpate

10

Triceps Brachii rupture MOI, SS

MOI- Direct blow to posterior elbow

S+S- 80% avulsed olecranon
- Pain/swelling
- palpable defect/ step off
- can’t extend arm

11

Anterior capsulitis S+S

defuse anterior elbow pain, deep tenderness

12

Dislocation of pro radial head MOI, SS

MOI- longitudinal traction of extended + pronated upper extremity

SS- deep tenderness on palpation

13

Ulnar Dislocation MOI

MOI- hyperextension/ sudden valgus force

14

Nerve entrapments

Cubital tunnel
Pronator Syndrome
Radial tunnel

Cubital- Ulnar nerve
Pronator- Median
Radial- Radial

Test- Pinch test/ weakness
