Posttraumatic locked dislocation of congenital pseudarthrosis of the clavicle

Congenital pseudarthrosis of the clavicle is a rare condition. It is generally right-sided but some cases involving the left side have been described. It is usually associated with dextrocardia. A few cases of nonfamilial bilateral pseudarthrosis have been reported. We describe a case of traumatic, locked dislocation of a congenital pseudarthrosis of the right clavicle after a road traffic accident injury. Operative treatment with reduction, resection of the pseudarthrosis margins, plate fixation, and bone grafting was necessary, with uneventful healing and union. To the best of our knowledge, there are no previous reports of such an injury.
