- Discussion and Classification
- Exam Findings:
- brachial plexus
- ref: Injury to the brachial plexus by a fragment of bone after fracture of the clavicle
- Radiology:
- Serendipity View
- best visualized sitting up w/ AP view & view w/ beam angled 30 deg. cephalad;
- w/ frx of clavicle, distal fragment & arm tend to sag, while proximal fragment, held by SC joint tends
to point upward;
- in any clavicular frx, carefully scutinize x-rays for presence of scapular frx, which represents
a floating shoulder;

- Upright versus supine radiographs of clavicle fractures: does positioning matter?
- Non Operative Treatment:
- it is difficult to reduce and maintain the reduction of clavicle fractures;
- despite deformity, healing usually proceeds rapidly;
- union usually occurs rapidly & produces prominent callus;
- w/ midshaft fractures, there will also be some degree of malunion;
- in these patients be attentive to medial cord nerve symptoms (more often ulnar nerve);
- distal clavicle fractures may have a high incidence of non union but most of these are asymptomatic, and of these
only a small number will be severe enough to require surgery;

- Non Union and Malunion of the Clavicle:
- defined as absence of radiographic healing by 4 months;
- non unions occur in more severe traumatic injuries;
- occurs most often in the central third where the clavicle lacks abundant muscular coverage;
- in mid-clavicular region, deforming forces include pectoralis major (pulls distal fragment inferiorly and medially) and
sternocleidmastoid (pulled superiorly);
- note that the diagnosis of clavicular non union can sometimes be difficult (because 2 orthogonal views cannot be obtained), and
supermposed ends of the clavicle on the AP view can give the false impression of union;
- exam:
- note function of brachial plexus (esp lower trunk);
- r/o presence of thoracic outlet syndrome;
- management:
- intra-medullary clavicular fixation:
- iliac crest bone grafting;
- internal or external bone stimulator;
