**9. Fractures of forearm**

Fracture of the forearm is extremely rare and may be a sign of the underlying bone fragility, with similar fractures in the femur or humerus. Child abuse must be ruled out. Extremely rare is the report of a constriction band in the forearm with fracture of the underlying radius and ulna, with severe compromise of the vascularity of the forearm. Pseudorarthrosis of the radius or ulna as signs of neurofibromatosis are rarely diagnosed in the neonatal period. Hyperostosis of the forearm (Caffeys disease) is among the extremely rare cases with x-ray similar to neonatal fracture [66–70] (**Figures 23** and **24**).
