MSK ramey and ferrill Flashcards
rotator cuff (RC) injuries
- Dx specific to tendinous attachments of mm
- usually d/t chronic repetitive microtrauma, acute macrotrauma, or combo
- MC sports related injury
subscap
major inferior attachment of RC
internal rotation of humerus and downward rotation of head in GH joint
supraspinatus
- superior attachment of RC
- major mm affected in impingement syndrome bc under coracoacromial lig
- elevation and abduction of humerus and upward traction of head in GH
infraspinatus
post-sup attachment of RC
external rotation of humerus and downward traction of head in GH
teres minor
post inf attachment of RC
external rotation of humerus in concert w/infraspinatus and downward traction of head in GH
what is the major mm involved w/impingement syndrome?
supraspinatus
impingement interval
space btwn undersurface of acromion and superior aspect of humeral head
maximally narrowed when arm ABducted
primary impingment
most common
impingement of RC mm/tendons from anatomical restriction and repetitive motion (especially elevation and internal rotation)
secondary impingement
- may result from pain which causes reflex inhibition and weakness of RC mm -> fail in fnx to center humeral head
- subsequent superior translation adds to impingement
symptoms of impingement syndrome
- varies from minimal pain w/activity to marked tendinitis, significant pain and decreased ROM
- if pain and decreased ROM severe think tear
PE impingement syndrome
-observe scapulothoracic motion while pt abducts shoulder
-firing of upper traps and weak scapula stabilizing mm -> slight winging
-painful at 90-120 degrees of abduction
+ neers and hawkins
neers
internally rotate arm and passively bring into flexion -> pain
hawkins
arm and elbow flexed at 90 and passively internally rotated -> pain
x-ray for subacromial space
scapular Y view
AP view good for GH and sclerosis of greater tuberosity
what are MRI and US good for
grade II lesions
who needs surgery
younger pts w/full thickness tears
conservative therapy
strengthening Ice-after use heat and massage- before use meds-NSAIDs steroid injection rest
biceps tendinitis
inflammation of biceps tendon secondary to repetitive use or sudden violent extension of elbow
biceps tendinitis PE
-tenderness on palpation of groove, sometimes crepitus or snapping w/flexion
