title: Development of pseudarthrosis in a dysplastic clavicle: A variant of congenital pseudarthrosis?
abstract: The development of a pseudarthrosis is reported in a child's right clavicle, which was previously noted to have been morphologically abnormal. Such pseudarthroses are uncommon, but they usually appear on the right side and may rarely be bilateral. The differential diagnosis is of a postpartum fracture, a posttraumatic pseudarthrosis, cleidocranial dysostosis, or neurofibromatosis. A review of the development of the clavicle and the hypotheses for such anomalous development are given.
