Question | Answer |
---|---|
Reversible cuff edema, hemorrhage...what stage of shoulder impingement? | stage I |
Irreversible fibrosis, tendinitis...what stage of shoulder impingement? | Stage II |
Partial or complete tear...what stage of shoulder impingement? | Stage III |
What is the most common acromial morphology? | type II 43% |
Where is the avascular zone of the supraspinatus? | 1cm proximal to the insertion into the greater tuberosity |
Where is the avascular zone of the biceps? | region of tendon that passes over humeral head |
What does the following describe? Age-related thinning, degeneration, and weakening, Permits proximal humeral migration into the CA arch, Vicious circle leading to full-thickness tears | RC tendinopathy |
What stage of impingement does the following describe? < 25 y/o, Reversible lesion, Pain after (progressing to during) activity, Often overhead sports/activities. | Stage I: reversible cuff edema, hemorrage |
What stage of impingement does the following describe? 26‐40 y/o, Prolonged history, Discomfort often worse at night, May have pain after activity or at rest, Inability to perform maneuver that elicits pain (overhead activities) | Stage II: irreversible fibrosis, tendinitis |
What stage of impingement does the following describe? >40 y/o, May/may not have weakness (cuff integrity), Significant cuff degeneration or partial cuff tears (avg. 50 y/o), Full thickness tears(Avg. 60 y/o) | Stage III: partial or complete tears |
Pain during activity, at rest, at night, Frequently biceps involvement, AC pain, Pain‐related weakness, Minor insults may extend a degenerative/partial RC tear...what stage of impingement does this describe? | Stage III |
What percent of cuff tears occur in sedentary individuals? | 70% |
Are RC tears always symptomatic? | no |
T or F? RC degeneration is a natural phenomenon of aging. | T |
According to the Neer 1980 study, does the prescence of massive rotator cuff tears imply progression to cuff tear arthropathy? | no |
Impingement may lead to _____ rupture? | biceps |
How can a biceps rupture cause a RC impingement. | part of the biceps function is to depress the humeral head, rupture causes superior mvmt of the humeral head and can cause impingement |
In young pts, what kind of trauma is required to tear the biceps? | violent |
What is the common tear location of a biceps tear? | at the musculotendinous junction |
Is impingement a common cause of biceps tears in the young? | no |
Impingement of the rotator cuff (or biceps) beneath the coracoacromial arch is what king of impingement? primary or secondary? | primary |
What kind of impingement is associated with alterations in: Anterior 1/3rd of acromion, Coracoacromial ligament, AC joint?(primary or secondary) | Primary impingement |
What kind of impingement is caused by a relative decrease in the subacromial space due to glenohumeral instability or functional scapulothoracic instability?(primary or secondary) | secondary |
_____= open surgical procedure that will allow for better fixation, but more precautions after surgery (active/resisted flex b/c delt released from ant acromion. | Arthrotomy |
_____= surgical procedure where visualization is great and allows for less precautions in rehab, but fixation not as good as open technique. | Arthroscopy |
_____= surgical procedure where deltoid splitting is used for visualization; involveds supraspinatus +/- infra, T minor (depends on size of tear) | Mini-open rotator cuff repair |
