The fracture around the elbow is frequent in the children. The cubitus varus and cubitus valgus deformities are the common late complications of the elbow fracture. The reason of correction for these problem is not the elbow fuction, but the cosmetic problem of tardy ulnar nerve palsy.

We performed five supracondylar osteotomies that are modification of Milch osteotomy from Mar, 1988 to Jan, 1989 of which four cases were cubitus varus and one case was cubitus valgus at In Chon Christian Hospital.

The results were as follows;

1. the cubitus varus deformities were four cases and the cubitus balus deformity was one.

2. The injuries were supracondylar fractures of the humerus for the cubitus varus and lateral condyle fracture of the humerus for the cubitus valgus.

3. The result was excellent by modified Milch osteotomy with derotation in the case of rotational deformity.

4. In adult, the bone healing was promoted by deepening the triangular shaped notch in the Milch osteotomy by widening the contact surface.
