Q

Severity of AC separation?

A
  • varies as well as expected time of recovery
  • could have involved disruption of CC ligaments and AC ligament

  • full PROM but limited AROM
  • weakness in external rotation = infraspinatus tera
  • weakness w/ empty can: supraspinatus
  • weakness w/ internal rotation = subscap
  • xray will have subtle findings but most time negative
- special tests:
Bear hugger test = subscap 
lift off = subscap
belly compression = subscap
\+ Hawkins, + neers

What is calcific tendonitis?

A
  • deposition of Ca++ “hydroxyapatite” the rotator cuff tendon - supraspinatus MC
  • diff consistency of Ca++ deposit, during liquid/tooth paste phase more painful and inflammatory
  • chalk consistency more dormant and no inflammation, less pain
21
Q

24
Q

What is adhesive capsulitis? RFs? 3 phases?

A
  • frozen shoulder is a loss of motion of shoulder as a result of tightening and shrinking of the shoulder capsule

28
Q

Labral injuries are common in what pop? Describe the injury?

A

- + obrien test = SLAP tear

31
Q

Tx for labral tear?

A
  • tx is conservative w/ no significant time off needed from sports
  • PT for rotator cuff strength and stabilization
  • if pain is presenting despite conservative measures then surgical repair
32
Q

Impingement problems of the shoulder?

A
  • posterior impingement is common in throwers due to increased laxity to anterior shoulder capsule during cocking phase of throwing and tightness in the back (pain and impingement occurs in acceleration and deceleration phase)
  • most will complain of pain in back of shoulder getting worse while throwing
  • tx w/ aggressive stretching program for anterior capsule of shoulder and strength program for rotator cuff
33
Q

When do shoulder dislocations commonly occur? Which dislocation is more common?

A
  • occurs most often due to elevation and external rotation of the shoulder
  • anterior much more common than dislocation
  • *** posterior dislocation more common in fb linemen due to blocking position, also result of seizure and electrocution
  • if you see bony bankart (part of glenoid bone broken off - indicates that labrum and ligaments in front part of shoulder aren’t attached to glenoid) : need surgery
34
Q

Clinical presentation of anterior dislocation?

A
  • pain following an injry: felt a pop and sensation of dislocation w/ signifcant pain. May stay out and need to be reduced or self reduces
  • 1st time dislocation is tx w/ reduction of dislocation and early immobilization
  • PT to work on shoulder stabilization w/ rotator cuff strengthening
35
Q

exam findings of anterior dislocation?

A
    • apprehension sign
    • relocation sign (after + apprehension test, provides relief to pt)
  • increased anterior translation
  • pain w/ ROM and guarding w/ reaching overhead
36
Q

Tx of anterior dislocation?

A
  • xray to r/o ant/inf glenoid fracture “bony bankart”
  • x ray hillsachs deformity
  • PT to work on cuff strength and stabilization
  • return to play roughly 4-6 wks and may reqr bracing to prevent re-dislocation
  • recurrent dislocations will rqr surgery
  • MRI of shoulder if older than 50 to r/o tear
37
Q

Tx of posterior dislocation?

A
  • tx conservatively w/ reduction and immobilization
  • PT to work on rotator cuff strength exercises
  • bracing may help w/ prevention
  • recurrent dislocation reqr surgery to stabilize
38
Q

Etiologies of posterior dislocation?

A
  • MC in linemen due to blocking or being blocked
  • shoulder will get forced out the back by getting struck in shoulder or by blocking an immovable object

41
Q

Tx of shoulder instability?

A
  • tx w/ aggressive PT to strengthen scapular stabilizers as well as rotator cuff
  • surgical intervention is last tx option
42
Q

What is glenhumeral OA? RFs?

A

46
Q

What is parsonage turner syndrome?

A
  • brachial plexus neuritis or neuralgic amyotrophy, is condition characterized by inflammation of network of nerves that innervate the muscles of chest, shoulders, arms “suprascapular nerve”
  • although individuals w/ condition may experience paralysis of affected areas for months or in some cases years, recovery is usually eventually complete
  • usually follows viral URI, white knuckle pain, risk of shoulder wasting away
47

Other shoulder conditions an injuries?

A
  • stinger or brachial plexus traction injury: fb player, unable to move or feel arm
  • proximal humerus fracture: elderly women falling
  • scapular fractures: high impact, dirt bike, fall off roof
  • long thoracic nerve injury “scapular winging”: vball player - constantly serving, serratus anterior affected, can’t do push up w/o scapula winging out
  • OA of AC jt: rfs - AC sep, bench press, tx: steroid injection, surgery
  • long head biceps rupture: 60 yo throwing bales - feels electric shock, bruise and popeye deformity, tx: reassurance, assoc of rotator cuff degeneration
  • spinoglenoid cyst: kid w/ weakness w/ resistance on external rotation - tear of labrum, form cyst on posterior aspect of labrum, take out cyst, and fix labrum
