Answer

Group I fractures (middle third of the clavicle) have been associated with injuries to the neurovascular bundle and the pleural dome.

Neurovascular compromise can develop from exuberant callus formation or from malunion. The medial cord and ulnar nerve are affected most often; treatment is surgical in nature. Brachial plexus compression resulting from hypertrophic callus formation may cause peripheral neuropathy.
