Anatomy and PE of the Upper Extremities Lecture Powerpoint Flashcards
__ joint is the only bony attachment of the upper extremity to the axial skeletal
Sternoclavicular joint
Coracoclavicular and acromioclavicular ligaments
2 ligaments that attach the clavicle to the scapula
For full 180 degree elevation of the humerus, 120 degrees is done at this joint and 60 at this (scapulothoracic rhythm, 2:1 ratio between them with early stage being elevation from the first, intermediate transition, and end stage motion primarily from the second)
Glenohumeral, scapulothoracic
3 components that provide stability to a oint
- structure
- ligaments
- musculature
4 components of the rotator cuff
Supraspinatus
Infraspinatus
Teres minor
Subscapularis
Coracoacromial arch
Ligament that creates a hood between the coroacoid and acromion process, problematic if humerus rides high and migrates superiorally and hits against it causing shoulder impingement syndrome
Sulcus sign
Test for glenohumeral instability in the shoulder, when elbow is grasped and forced downward see depression form just below the acromion
Winging of scapula
Have patient push against the wall and see scapula wing out indicative of….
Apley’s scratch test
Quick assessment of shoulder range of motion by having patient reach behind them and scratch their back in a stereotypical manner
Apprehension test
Test glenohumeral joint anterior instability by having arm abducting and externally rotated, then apply force posteriorly and watch for apprehension
Relocate release test
Done if positive apprehension test to test glenohumeral joint anterior instability by abducting and externally rotating arm then applying force posteriorally and with the other hand blocking off anterior motion of the shoulder, then release and should see apprehension return
Load and shift test
Test for anterior and posterior glenohumeral joint instability, stabilize shoulder joint and apply anterior or posterior translation for laxity
Speeds test
Resisted glenohumeral flexion while elbow is extended testing for pressure over biceps tendon, pain indicates biceps tendon pathology
Drop arm test
Tests for rotator cuff lesion, patient abducts arms to 90 degrees, lowers them slowly, examiners taps the arms forcing them into adduction, pain or instability to resist the tap indicates pathology
Empty can test
Test for supraspinatous rotator cuff lesion, eximiner resists shoulder abduction while arms are in scapular plane with thumb pointed down as though emptying a can
