Posttraumatic nonunion of the clavicle in a 13-year-old boy causing an arteriovenous fistula.

CONTEXT: Fractures of the clavicle are one of the most common injuries to the bone in childhood, but posttraumatic nonunion of pediatric clavicle fractures are extremely rare, with only isolated reports in literature.

CASE REPORT: We report a case of a posttraumatic painful nonunion of a clavicle fracture in a 13-year-old boy that caused symptomatic compression of the external jugular vein (EJV) and the formation of an arteriovenous fistula. The fracture was treated successfully with open reduction and internal fixation with a contoured recon plate 6 months following the injury. The fistula was treated by ligation and closure.

CONCLUSION

The patient made a full recovery 6 months following surgery and was asymptomatic with full range of shoulder movement. Fracture union was confirmed by computed tomography (CT) scanning and no residual fistula was found.
