Familial pseudarthrosis of the clavicle: does it need treatment?

The eighth family with multiple cases of congenital pseudarthrosis of the clavicle is described. This usually presents as a clavicular lump and is distinct from more common conditions such as birth fractures, craniocleidal dysostosis and neurofibromatosis. There has so far been no clear indication on whether familial pseudarthrosis of the clavicle should be treated operatively. We recommend that when a suspected case of congenital pseudarthrosis of the clavicle is diagnosed the parents and siblings be examined also. If other family members are affected, we advise that the treatment should be conservative.
