Three-Dimensional Corrective Osteotomy for Treatment of Cubitus Varus after Supracondylar Fracture of the Humerus

Cubitus varus deformity after supracondylar fracture of the humerus in children generally includes deformities of varus, hyperextension and internal rotation. Recently almost all corrective osteotomies for treatment of the varus deformity have been limited to correction of only the varus or of the varus and hyperextension deformity. Electromyographic study has revealed unphysiological joint motion and muscle activity around the joint in elbows with cubitus varus, hyperextension and internal rotation deformity. On this basis we have successfully attempted simultaneous correction of all three deformities. The end results in ] 3 elbows have been satisfactory without any complications such as delayed union, limitation of elbow motion or nerve palsy. In conclusion, we recommend simultaneous correction of the three elements of cubitus varus deformity to restore anatomic alignment of the elbow joint.
