1

what is most effective passive stabilize of shoulder joint?

-vacuum phenomena of bone in socket

-labrum also very important

2

why avoid NSAIDs in treating fracture?

NSAIDs interere with bony healing via PGs. PGs contribute to bone healing.

2

shoulder dislocation: 

-what nerves are vulnerable? what to look for?

-Axillary and musculocutaenous nerves are vulnerable.

-check deltoid function with arm abduction--first 30 degrees is supraspinatus, then deltoid

-check sensory on deltoid and forearm (musculocutaneous)

3

3

clavicular fractures

-grades

grade 1. fx, no ligament disruption so no displacement

2. fx, with tear of CC ligament. so upward dispacement of medial clavicular fragment

3. fx through AC joint, no displacement

4

capsulitis of shoulder

-mech

-etiology

-clinical findings

-Tx

-inflammation of capsule

-etiology unknown (sometimes follows trauma)

3 clinical stages:

1. freezing (pain, losing ROM)

2. frozen (no pain, no ROM)

3. thawing (no pain, increase ROM)

Tx: reassurance because usually self-limiting. (thawing may take 1/2 to 2 years). can use NSAIDs

5

AC injury grades

grade 1--AC ligament injury

2--AC ligament tear, CC stretch

3--complete AC and CC ligament tears

6

Biceps brachii proximal long head rupture:

tx?

-leave as is. Still have function with other muscles.

-only tx is if person is professional bodybuilder for aesthetics

7

carpal tunnel syndrome

-clinical findings

median nerve.

-sensation: first 3 1/2 fingers.

-motor: thenar muscles. can result in thenar wasting

 

9

medial epicondylitis

'golfer's elbow'

-strain of wrist flexors

11

Bones with vulnerable blood supply (3)

1. scaphoid--radial artery

2. talus

3. femoral head (adults)--medial circumflex femoral

12

lateral epicondylitis

'tennis elbow'

-strain of wrist extensors (most likely extensor carpi radialis)

13

For OA arthrtitic joint, what 2 things can you inject?

1. steroids

2. hyaluronic acid (viscosupplementation injection)--give building blocks of articular surface

14

what is joint subluxation?

partial displacement, not full dislocaiton

15

AC sprain

-what exam tests/findings?

1. cross-arm flexion test

-have person raise arm to 90 degrees, then adduct over chest to elicit AC pain.

2. painful arc of abduction over 150 degrees

16

shoulder impingement tests:

(3)

1. hawkin's ('like a hawk handler') --internally rotate shoulder

2. neer's ('near the ear')

3. jobe's (empty can)
