Elbow/forearm

Question 1

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

Answer 1

humeroulnar- flex/xtend

humeroradial- flex/extend
- sup/pro

prox radioulnar- sup/pro

distal radioulnar- sup/pro

Question 2

Ulnar collateral lig- 3 sections

Answer 2

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

Question 3

lateral collateral lig
radial collateral lig
annular lig

Answer 3

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

Question 4

Median/ulnar/radial nerves what do they supply

Answer 4

median- wrist flexors/extensors

ulnar- 4th/5th digits

radial- digit extensors, thumb, wrist

Question 5

ulnar collateral lig MOI, SS, Test

Answer 5

MOI- valgus force, repetitive throwing

SS- localized pain that worse w/ movement

Test-valgus stress test

Question 6

Osteochondritis Dissecans of Capitulum MOI, SS

Answer 6

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

Question 7

Lateral Epicondylagia MOI, SS, Test

Answer 7

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

Question 8

Media epicondylagia MOI, SS

Answer 8

MOI- Activates involving swift+ powerful snapping of wrist

SS- Point tenderness @ origin of wrist flexors

Question 9

Distal Biceps tendon rupture MOI, SS

Answer 9

MOI- tendon degrades w time, sudden eccentric load

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

Question 10

Triceps Brachii rupture MOI, SS

Answer 10

MOI- Direct blow to posterior elbow

S+S- 80% avulsed olecranon

   - Pain/swelling
    - palpable defect/ step off
    - can’t extend arm

Question 11

Anterior capsulitis S+S

Answer 11

defuse anterior elbow pain, deep tenderness

Question 12

Dislocation of pro radial head MOI, SS

Answer 12

MOI- longitudinal traction of extended + pronated upper extremity

SS- deep tenderness on palpation

Question 13

Ulnar Dislocation MOI

Answer 13

MOI- hyperextension/ sudden valgus force

Question 14

Nerve entrapments

Cubital tunnel
Pronator Syndrome
Radial tunnel

Answer 14

Cubital- Ulnar nerve
Pronator- Median
Radial- Radial

Test- Pinch test/ weakness
