Shoulder & Elbows dislocations Flashcards
A/C joint separation
Acromioclavicular joint disruption and seperation
Anterior shoulder D.
Involves the glenohumeral joint w/ the humeral head displaced anteriorly and inferiorly: may be associated w/ one of the following
Bankhart lesion / Hill-Sachs Lesion
Bankhart Lesion:
Seen surgically as detachment of glenoid labrum and sometimes a bone fragment from glenoid: Perthes-Bankhart lesion
Hill-Sachs lesion:
Seen radiographically as an indentation of the posteromedial humeral head: which occurred at the time of the dislocation.
Locked Scapula
Rare scapulothoracic dissociation w/ entrapment of scapula into chest wall or w/ anterior displacement: ussually associated w/ severe neurovascular injury
Luxatio erecta
dislocation of shoulder so that the arm stands straight up over the head w/ humerus locked in 110* to 160* abduction
Multidrectional instability
shoulder that is unstable in multi planes, commonly anterior inferior and posterior inferior planes
Posterior shoulder D.
involves the glenohumeral joint w/ the humeral head displaced psoteriorly
Reverse Bankhart Lesion
Seen surgically as a detachment if tge rim of the posterior labrum from the glenoid rim
Reverse Hill-Sachs lesion:
Defect of anteromedial humeral head: may be seen on radiographs or at surgery
Sternoclavicular loint separation
Disruption of the sternoclacicular joint
Subcoracoid D
glenohumeral D. w/ the humeral head displaced medially
Subglenoid D.
glenohumeral dislocation w/ the humeral head displaced inferiorly
Direct injury D.
posterior displacement of the olecranon
Divergent D.
ulna and radius are dislocated separately
