[Malunion and growth disorders following fractures of the condylus radialis humeri in children].

Basing on the results of 46 fractures of the lateral humeral condyle in children possible mal-unions and disturbances of growth after conservative and operative treatment are shown. Varus-tendency of the elbow axis was observated in 23% after conservative treatment of undisplaced fractures and in 37.5% after open reduction and Kirschner wiring of displaced fractures. Fish-tail deformity was seen both after conservative treatment and fixation with Kirschner wires; only open reduction and osteosynthesis with small-fragment screws could avoid this two disturbances of growth. One non-union was seen after conservative treatment.
