|
Definition
|
|
Term
|
Definition
excessive external rotation and abduction, middle GH ligament, resultant f rom dmirect blow |
|
|
Term
|
Definition
rare, resultant from flexion and internal rotation along with longitudinal force (blocking in football), weakness in subscapularis muscle |
|
|
Term
|
Definition
loss of control of small arthrokinematic joint movements that occur when patient tries to stabilize the joint during movement |
|
|
Term
|
Definition
Excessive or gross physical movement in a joint where patient becomes apprehensive at end of ROM (subluxation or dislocation is imminent) |
|
|
Term
|
Definition
Either an inability to control ROM consciously or unconsciously |

|
Term
|
Definition
tear resultant from dislocation or anterior instability (posterior aspect of humeral head) |

|
Definition
inferior GH ligament avulsed from labrum, crepitis as humeral head moves against anterior labrum |
|
|
Term
|
Definition
superior labrum anteroposterior lesion - small articular defect on humeral head (due to impact of humeral head and glenoid fossa when trying to relocate), falling on outstretched arm, excessive forceful biceps contraction |
