[Differential treatment of proximal humerus fractures in childhood].

In proximal humeral fractures with first degree displacement and in fractures with second degree displacement, which primarily prove to be stable, reduction is not necessary. Closed reduction is indicated in unstable fractures with second degree displacement and in all fractures with third degree displacement. If closed reduction fails to improve the position of the fracture, open reduction and Kirschnerwire transfixation should be performed. Retention for two to three weeks is sufficient.
