AC seperation differential Dx

A

Chronic conditions can increase stress to RC Concomitant clavicle fracture RC tear

35
Q

AC seperation Tx

A

varies on grade, typically grade I, II, and usually III do not require surgery - grades higher than III do require surgery

36
Q

Acute Bursitis/Calcific Tendonitis Hx and demographic

A

Idiopathic; can result from Tendonosis or viral infection Women > men Middle age > older > younger

37
Q

Acute Bursitis/Calcific Tendonitis presentation

A

Capsular pattern: ER > ABD > IR Joint play restrictions in all directions, especially inferiorly: Histological changes in area of redundant fold Chronic cases can lead to secondary impingement

38
Q

Acute Bursitis/Calcific Tendonitis differential Dx

A

Impingement Subscapularis spasm/tightness

39
Q

Acute Bursitis/Calcific Tendonitis Tx

A

Regain motion at GH joint Regain ST rhythm Strengthen Typically self-limiting within 6-12 months Aquatic therapy should be considered

40
Q

Bicipital Tendonitis Hx

A

Overuse/overtraining Overhead sports with racquet/throwing Pain at anterior shoulder

41
Q

Bicipital Tendonitis presentation

A

Tenderness along Long Head of Biceps tendon (proximal portion) (+) Speeds test Pain with resisted shoulder flexion (typical); elbow flexion (occasional) (+) Horizontal Adduction with overpressure for symptom reproduction

42

A

similar to stage 3

48
Q

Describe Primary Impingement

53
Q

Describe Secondary Impingement

A

Narrowing of the subacromial space due to glenohumeral or scapulothoracic instability. Attempts by RC to compensate for lack of ligamentous/capsular stabilization results in fatigue of RC and superior migration of humeral head

54
Q

Secondary Impingement Hx

A

Younger populations Typically participate in overhead sports: combinations of school and community league sports does not allow for “off-season” in pre/adolescent populations reports of “arm going dead”

57
Q

Posterior (Internal) Impingement: population and Hx

Typically in overhead athletes (tennis players, swimmers, throwers) During ABD+ER (cocking phase) the supraspinatus and infraspinatus muscles get ‘pinched’ at superior/posterior glenoid Occurs on undersurface (instead of bursa side) of RC Typically associated with anterior instability

58
Q

Describe Neer

A

Maximal passive flexion of arm (overhead) compresses greater tuberosity against anteroinferior acromion

59
Q

Describe Hawkins-Kennedy
