Q

what is most effective passive stabilize of shoulder joint?

A
  • vacuum phenomena of bone in socket
  • labrum also very important
2
Q

why avoid NSAIDs in treating fracture?

A

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

2
Q

shoulder dislocation:

-what nerves are vulnerable? what to look for?

A
  • 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
Q
A

Q

clavicular fractures

-grades

A

grade 1. fx, no ligament disruption so no displacement

  1. fx, with tear of CC ligament. so upward dispacement of medial clavicular fragment
  2. fx through AC joint, no displacement
4
Q

capsulitis of shoulder

  • mech
  • etiology
  • clinical findings
  • Tx
A
  • 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
Q

AC injury grades

A

grade 1–AC ligament injury

2–AC ligament tear, CC stretch

3–complete AC and CC ligament tears

6
Q

Biceps brachii proximal long head rupture:

tx?

A
  • leave as is. Still have function with other muscles.
  • only tx is if person is professional bodybuilder for aesthetics
7
Q

carpal tunnel syndrome

-clinical findings

A

median nerve.

  • sensation: first 3 1/2 fingers.
  • motor: thenar muscles. can result in thenar wasting
9
Q

medial epicondylitis

A

‘golfer’s elbow’

-strain of wrist flexors

11
Q

Bones with vulnerable blood supply (3)

A
  1. scaphoid–radial artery
  2. talus
  3. femoral head (adults)–medial circumflex femoral
12
Q

lateral epicondylitis

A

‘tennis elbow’

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

13
Q

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

A
  1. steroids
  2. hyaluronic acid (viscosupplementation injection)–give building blocks of articular surface
14
Q

what is joint subluxation?

A

partial displacement, not full dislocaiton

15
Q

AC sprain

-what exam tests/findings?

A
  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
Q

shoulder impingement tests:

(3)

A
  1. hawkin’s (‘like a hawk handler’) –internally rotate shoulder
  2. neer’s (‘near the ear’)
  3. jobe’s (empty can)
