Operative Treatment of Clavicle Fractures:

- Discussion:
    - indications for surgery:
            - open fracture
            - gross displacement of fracture w/ tenting of skin
            - fractures w/ signficant medialization (causing medialization of the shoulder girdle); 
            - ref: Fixation of Displaced Midshaft Clavicle Fractures in Skeletally Immature Patients
    - surgical considerations: 
            - subclavian artery (axillary artery begins as it crosses the first rib)
            - brachial plexus (esp lower trunk damage (C8, T1); 
            - look for posterior cord injury
            - references:
                   - Injury to the brachial plexus by a fragment of bone after fracture of the clavicle.
                   - Clavicular caution: An anatomic study of neurovascular structures.
    - floating shoulder:
            - multiple authors have reported excellent results with healing rates greater than 99% for variety of immobilization techniques;
            - incidence of nonunion, malunion, NV complications total < 1%;
            - single disruptions of SSSC have uniformly good results with nonoperative treatment;
            - double disruptions of SSSC are a combination of innocuous injuries which create instability for UE best surgically treated
            - ORIF simpler fracture reduces other injury satisfactorily

- Surgical Choices:
      - intra-medullary clavicular fixation: 
          - references:

    - plate fixation: (Synthes Clavicle Products) 
            - consider unicortical fixation with a Synthese 3.5 mm pelvic reconstruction locking plate (unicortical screws will not risk
                      injury to the deep neurovascular structures;  (axillary artery)
            - post op exam includes neurovascular check - check for full abduction and ext rotation (inorder to test for thoracic outlet syndrome); 
            - careful to note potential vascular complications;
                       - references:

                             - Safe drilling angles and depths for plate-screw fixation of the clavicle: avoidance of inadvertent iatrogenic subclavian neurovascular bundle injury.
            - advantages of anteroinferior plating:
                       - include less hardware prominence and the ability of the surgeon to direct instrumentation away from infraclavicular neurovascular structures;
