Congenital pseudarthrosis of the tibia associated with cleidocranial dysostosis and osteogenesis imperfecta. A case report.

A neonatal boy with cleidocranial dysostosis presented with congenital pseudarthrosis of the tibia. Clinical observation later revealed he also had osteogenesis imperfecta. The osteogenesis imperfecta was classified as Type I and the congenital tibial pseudarthrosis as Type II. Cleidocranial dysostosis, osteogenesis imperfecta, and congenital pseudarthrosis of the tibia have not been previously reported to coexist in one individual.
