Long-term review of thirty-eight supracondylar humeral fractures in children demonstrated cubitus varus deformity in ten cases (26.3% of patients). The majority of cubitus varus deformity were noted in the patients treated by plaster cast. The deformity occurred more frequently in the cases with medial displacement (particularly medial tilt) than with lateral displacement. There is no case that the varus deformity occurred due to growth imbalance.
