- typically congenital pseudarthrosis of the clavicle causes little discomfort and requires no treatment;
- ORIF & bone grafting are performed if cosmesis or functional capacity are not satisfactory;
- in the report by Lorente Molto FJ, et al, the authors reviewed six cases of children with congenital pseudarthrosis of the clavicle;
