Bilateral congenital seudarthrosis of the clavicle. A clinical case

Congenital pseudarthrosis of the clavicle is a rare malformation in which the aetiology is still unclear. Bilateral involvement is exceptional. Although it is a congenital malformation, it may not be diagnosed until late childhood, with patients presenting with a painless deformity of the middle third of the clavicle in the absence of prior trauma. The treatment is controversial, and may be surgical, depending on the functional impact and aesthetics. A case of bilateral involvement is presented, together with a review of the relevant literature.
