Delayed brachial plexus neurapraxia complicating malunion of the clavicle.

Delayed brachial plexus neurapraxia is a rare complication of midshaft clavicular fracture. The symptoms are variable and occur insidiously. Surgical decompression to release the compression of brachial plexus is the treatment of choice and usually has a good result. We report a patient whose brachial plexus was compressed by malunion of the clavicle. This patient had a good outcome after treatment with intramedullary nailing and Knowles pin fixation after corrective osteotomy without bone grafting.
