Shoulder Instability Flashcards
Bankart lesion
tear of glenoid labrum in the anterior part
Bony bankart lesion
if part of bone comes off of glenoid with bankart lesion
Reverse bankart lesion
tear of glenoid labrum in posterior region
Hill-Sachs lesion
compression fracture of the humeral head occuring as result of traumatic dislocation anterior.
Damages posterolateral humerus
Moving in ER, ABD; force pushes it forward
Reverse Hill-Sachs lesion
compression fracture of humeral head occuring as result of a traumatic dislocation posterior.
damages anteromedial humerus
moving in IR, ADD; force pushes it back
Anterior instability
unidirectional with traumatic onset
ABD and ER (may have bankart)
Posterior instability
less common
unidirectional with repetitive loading (bench press)
ADD,IR, FLEX (may have reverse bankart)
Multi directional instability
congenital or acquired laxity
Biceps tendon/slap lesions
may or may not be associated with GH instability
injury of labrum at the attachment site of the long head of biceps
Anterior dislocations typically occur from what?
trauma or fall (elderly)
fall with a combo of ABD, EXT, and posterior force
Why would someone have acquired instability?
excessive ER
posterior joint tightness
strength imbalance
If someone had a traumatic injury, what does presentation depend on?
etiology
direction
severity
frequency
Acquired instability is a combo of what?
traumatic and atraumatic
Test item cluster for anterior instability?
apprehension test
relocation test
surprise test
anterior drawer
Test item cluster for posterior instability and labral tear
Jerk test -post
kim and biceps load test- labral tear
(not looking for pain, looking for click. consistent= tear, few times=instability)
