Congenital pseudarthrosis of the clavicle: a case presentation and review of the literature
Congenital pseudarthrosis of the clavicle is rare. The anomaly usually occurs in the right clavicle and is manifested by a painless and cosmetically unappealing mass. The greater the motion at the pseudarthrosis, the greater is the cosmetic deformity. The defect apparently occurs from an abnormal stimulus during the 45th day of fetal development. A case report has been presented and a differential diagnosis discussed. Treatment should be observation in those cases with a mild deformity, and surgical resection and stabilization in those with a severe deformity, with the surgery performed before the age of 8 yr.
