congenital pseudarthrosis of the clavicle: a clinical and radiological examination

Results of the clinical and radiological examination of 20 children aged between 2 years and 13 years with congenital pseudarthrosis of the clavicle are presented. In 35% cases, malformations of the cardiovascular and musculoskeletal systems were identified. The most common variants of the affected clavicle were shortening, localization of nonunion in the distal part of its middle third, and thinning. Less frequent deformations included thickening of the ends of the bone fragments with moderate sclerosis of all bone fragments and normal bone structure of the diaphysis; deformity of bone fragments (in 60% cases) mainly in the frontal plane; and the displacement of bone fragments in the cranial direction. These changes need to be considered when planning surgery.
