Figures A and B show a scapulothoracic dissociation, with significant lateralization of the scapula and widening of the acromioclavicular joint to over 4 cm (Figure A). This can be thought of as an internal disarticulation of the scapulothoracic association and acromioclavicular joints. The referenced article by Riess et al revealed that functional outcomes are worse with brachial plexus injuries and concomitant scapulothoracic dissociation than with isolated brachial plexus injuries. In fact, at 2 year follow-up, only 57% of the dissociation patients could carry anything over 5 lb with the injured side. The other referenced article by Zelle et al found that complete brachial plexus injuries portended the worst outcome for scapulothoracic dissociation injuries.
