From 1984 to 1995, 19 patients with cubitus varus resulting from supracondylar humeral fractures underwent lateral closing-wedge osteotomies at The Royal Alexandra Hospital for Children. As the indication for osteotomy in all cases was the cosmetically unacceptable cubitus varus, we reviewed the cosmetic results. Seventeen patients were available for review. Subjective reports from patients and parents, as well as objective clinical assessment by one of the authors, were used to assess these results. According to our grading system, 12 (76%) patients had excellent results. These patients and their parents were satisfied with the cosmetic results, and there was no clinical evidence of a bony prominence over the lateral condylar region or an unsightly operative scar. One patient had a poor result with a lateral bony prominence and an unsightly scar, both of which were clinically obvious. We report that lateral closing osteotomies in children who have not yet reached skeletal maturity produce excellent cosmetic results.
