Twenty-one elbows (20 patients) with varus and valgus deformities were treated with corrective osteotomy from 1966 to 1981. Eighteen cases of varus deformities were resulted from supracondylar fractures (7 cases) and diacondyle fractures (11 cases), and three cases of valgus deformities from radial condyle fractures. The age of the patients operated upon for the deformities were ranged from 4 to 23 years.
At the follow-up survey, the deformities resulted from supracondylar fractures were corrected satisfactorily, and the deformities from diacondyle and radial condyle fractures were not always corrected satisfactorily. This results gave that the cases with growth disturbance of the distal humeral end due to the epiphyseal separation, should not be operated before about 10 years. Concerning to the operative method, French and Zuggurtung methods gave good results, that is to say, the stability at the osteotomy must be kept until the bony callus appears.
