1. Shoulder fractures & dislocations

4.  Outstrech hand

5.  AP  30 degree cephalad view

7.  Injury to brachial plexus, great vessels, lungs  Malunion  Nonunion

8.  Anterior (95-97%)  Subcoracoid (most common)  subglenoid (1/3 associated with # greater tuberosity, or # glenoid rim)  subclavicular  Posterior  Inferior and superior

9.  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

11.  2-4% of shoulder dislocations  Secondary to seizure, direct blow to shoulder  Need to dx early to prevent long term complications

12. Adduction,int.rotation

13.  AP may appear normal!  “light bulb” – int rotation of humeral head

15.  1)Counter traction traction  2)stimson

16.  Mechanisms of Injury:  Fall on the tip of the unprotected shoulder.  Fall on the outstretched hand. 1)partial 2)complete

17.  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

19.  Diagnose X-ray

20.  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

21.  Rare  Most treated conservatively  Intraarticular displacement may need ORIF

23.  Conservative  OR

25.  Common anterior  Bankart leision  Hill-sachs leision  Apprehension test

26.  Diagnose)CT SCAN Lat.Rotation abduction
