[Spontaneous corrections, growth disorders and post-traumatic deformities after fractures in the area of the forearm of the growing skeleton].
Growth phenomena after paediatric forearm fractures are described. The capacity for spontaneous remodelling of malunions should be primarily considered in the treatment of fractures of the growing skeleton. Thus, unnecessary reductions, anaesthesia and posttraumatic deformities can be prevented. Generally speaking, a high remodelling capacity can be expected in cases of enough remaining growth, proximity to a physis with high activity, and if the main deformity lies in the plane of motion of the nearest joint. It is widely accepted that distal radius and/or ulna fractures are fully remodelled up to the age of 11 to 12 years. However, the remodelling capacity of fractures of the proximal and middle third of the shaft is smaller and less well known. Stimulating growth disturbances at the upper extremities are clinically of minor importance. Growth arrests are rare. Their fateful occurrence is not predictable and not closely related to fracture pattern or amount of dislocation.
