Nonunion of the Coracoid Base Secondary to Cutibacterium acnes Infection in a Surgically Naive Patient: A Case Report.
Overview
abstract
CASE: We present the case of a 42-year-old man with a coracoid base fracture that progressed to nonunion. The patient underwent percutaneous autologous bone-marrow and demineralized bone matrix (DBM) grafting 8 months after injury, with all intraoperative cultures positive for Cutibacterium acnes. The patient had no prior surgeries, but he began shaving his axillae around the time of injury. He was treated with amoxicillin; by the 6-week follow-up, computed tomography demonstrated complete fracture healing. CONCLUSION: Our case demonstrates a novel etiology of coracoid nonunion treated successfully by eradicating the infection with biologic augmentation by percutaneous autologous bone-marrow grafting with DBM and oral antibiotics.
