A Case of Bilateral Congenital Pseudoarthrosis of Clavicle: An Uncommon Variant of a Rare Disorder

Congenital pseudarthrosis of the clavicle (CPC) is a rare disorder diagnosed at birth or early childhood presenting with a painless, non-tender mass on the clavicle. Its etiology is unknown, caused by failure of fusion of the medial and lateral ossification centers of the clavicle. Left-sided CPC is rare and linked to other pathological abnormalities. Bilateral involvement is extremely rare and it is seen in association with other congenital malformations. A full-term newborn baby girl was examined after a complicated emergency cesarean section delivery. Upon initial pediatric examination, there was suspicion of bilateral clavicle fracture with no limitation of movement and equal moro reflex bilateral. Plain radiographs of the clavicle revealed a suspected bilateral fracture of the clavicle. At the two-month follow-up, X-rays were taken to assess the clavicle fractures showing persistent bilateral clavicle deformities and there was no interval callus formation which confirmed the diagnosis of bilateral CPC and excluded the presence of the fracture. Bilateral pseudarthrosis of the clavicle is a rare entity, and surgical correction is not required unless the patient develops symptoms of limitations of movement or for aesthetic causes.
