A New Three–Dimensional Osteotomy for Cubitus Varus Deformity After Supracondylar Fracture of the Humerus in Children

In the past, supracondylar osteotomy for the correction of cubitus varus deformity has been associated with a high failure rate and significant complications, even in simple lateral closing wedge osteotomy. This is because the supracondylar area is thin and fixation is difficult to maintain. In cubitus varus deformity, not only medial, but posterior, tilt and internal rotation of the distal fragment also frequently occurs. To correct all these deformities and to achieve a wide bony contact and more rigid fixation than simple lateral closing wedge osteotomy, we propose a new three-dimensional osteotomy. Among 12 patients who received this osteotomy, 11 had an excellent result and one had a good result.
