title: Congenital pseudarthrosis of the clavicle.
abstract: This is a report of 5 cases of congenital pseudarthrosis of the clavicle, a rare disorder of the shoulder girdle. Little more than 100 cases have been reported in the literature; 3 of our 5 cases represent a very rare form of left side involvement with dextrocardia. The pseudarthrosis mass generally protrudes under the skin and may need surgical correction. When unilateral, there is marked and unexplained predominance for the right side. Three cases required no treatment; 2 were successfully treated by excision of the bone ends, bone grafting and internal fixation.
