Shoulder fractures & dislocations
Outstrech hand
AP 30 degree cephalad view
Injury to brachial plexus, great vessels, lungs Malunion Nonunion
Anterior (95-97%) Subcoracoid (most common) subglenoid (1/3 associated with # greater tuberosity, or # glenoid rim) subclavicular Posterior Inferior and superior
Arm in abduction and external rotation. Force is taken on the hand or arm which increases the external rotation of the arm causing the head of the humerus to dislocate
2-4% of shoulder dislocations Secondary to seizure, direct blow to shoulder Need to dx early to prevent long term complications
Adduction,int.rotation
AP may appear normal! “light bulb” – int rotation of humeral head
1)Counter traction traction 2)stimson
Mechanisms of Injury: Fall on the tip of the unprotected shoulder. Fall on the outstretched hand. 1)partial 2)complete
Grade I Mild tenderness over AC joint, mild swelling Full ROM Grade II Mod/severe pain, clavicle slightly displaced up Grade III Arm kept in adduction, obvious deformity
Diagnose X-ray
Complete open reduction I and II Conservative (sling, ice, analgesia, physio) 6/52 before lifting III Conservative with late distal clavicle excision Refer to Ortho <72h
Rare Most treated conservatively Intraarticular displacement may need ORIF
Conservative OR
Common anterior Bankart leision Hill-sachs leision Apprehension test
