ABSTRACT

La pseudoartrosis congénita de la clavícula es una malformación rara y benigna, caracterizada por la ausencia del tercio medio de la clavícula. Suele ser unilateral y mayoritaria en el lado derecho. La etiología es desconocida y se postulan diversas teorías etiopatogénicas (vascular, embriológica y genética).Puede detectarse en el período neonatal o, más frecuentemente, durante la infancia. En ocasiones, puede ser sintomática. Puede requerir tratamiento mediante reconstrucción quirúrgica por injerto óseo.Se presentan 2 casos, uno de diagnóstico neonatal y otro de 3 años de edad realizados con 24 h de diferencia. Se destaca la consideración de este diagnóstico como diferencial de fractura obstétrica o postraumática, displasia cleidocraneal y neurofibromatosis de tipo 1.


The congenital pseudoarthrosis of the clavicle is a rare and benign malformation, characterized by the absence of the middle third of the clavicle. It is usually unilateral and the majority on the right side. The etiology is unknown, postulating diverse etiopathogenic theories (vascular, embryological and genetic).It can be detected in the neonatal period or, more frequently, during childhood. Occasionally it can be symptomatic. It may require treatment by surgical reconstruction by bone graft. Two cases are presented, one of neonatal diagnosis and another one of 3 years of age performed with 24 hours of difference. We emphasize on its consideration as a differential diagnosis of obstetric or post-traumatic fracture, cleidocranial dysplasia and neurofibromatosis type I.
