Abstract

Background:Congenital pseudarthrosis of the clavicle is a rare disease. There are about 200 individual cases reported so far in world literature, mainly in the form of case reports. The majority of authors recommend surgical. An analysis of 103 cases published since 1980 shows only a few post-surgical complications.Case Report: The authors present a female patient operated at the age of 4.5 years. During surgery both cartilaginous ends were resected and internal fixation was performed by a one-third semitubular plate fixed by 3.5 mm cortical screws. Ten days after hardware removal, a fracture occurred in the screw-hole following a minor impact. Surgery to heal the congenital pseudarthrosis was successful, but a new fracture occurred, resulting from bone weakening. This simple fracture was treated conservatively. At present (5 years after the first surgery) the patient’s parents are completely satisfied with both the functional result and the cosmetic appearance.Conclusions: The authors have not found in the literature any reports of similar complications after surgical treatment of this condition. The use of more delicate osteosynthetic material might prevent the complication described here.
