Congenital Pseudoarthrosis of the Clavicle in a Softball Player.

Abstract

Congenital pseudarthrosis of the clavicle remains remarkably rare, and the pathogenesis is unclear, but orthopaedic surgeons should be prepared to make this diagnosis and confident in the outcomes of open reduction and internal fixation with grafting. A 15-year-old female softball player presented with anterior shoulder pain during softball activities, with no precipitating trauma. She was diagnosed with congenital pseudarthrosis of the clavicle and initially treated conservatively. Following no improvement with physical therapy, home therapy, rest, and anti-inflammatory drugs, she was treated with open reduction and internal fixation of the clavicle with iliac crest autograft and demineralized bone matrix allograft.
