Supracondylar Osteotomy of the Humerus to Correct Cubitus Varus: Do Both Internal Rotation and Extension Deformities Need to Be Corrected?*

Abstract

For osteotomies to correct cubitus varus deformity, correction of internal rotation is not needed. With a three-dimensional osteotomy, it is difficult to maintain correction and to acquire the planned carrying angle because of the small area of bone contact. It is necessary to correct hyperextension in patients older than ten years of age, as after that age bone remodeling is not expected to increase elbow flexion.
