Outcomes of French's Corrective Osteotomy of the Humerus for Cubitus Varus Deformity in Children

Summary

Background:

Supracondylar humerus fractures are the most common elbow fractures in the pediatric population.

Objectives:

To evaluate the outcomes of French's corrective osteotomy for correction of post-traumatic cubitus varus deformity in children.

Method:

We conducted a retrospective review of medical charts of all patients who had undergone French's corrective osteotomy in our institution from 1998 to 2012. We recorded range of motion, cosmetic deformity, carrying angle, lateral cortex prominence index, hyperextension, and lateral cortex step before and after the surgery.

Results:

Seven patients were enrolled the study. Average follow-up time was 4.6 years (range 2–9 years). An average of 18.3º of limited flexion (range 5º–35º) compared to the healthy elbow was recorded in three patients. Lateral condylar prominence was recorded in one patient. The average preoperative carrying angle was -20.5º (range -15º–30º) and postoperative angle was 9.6º (range 7º–13º). In comparison, the average carrying angle in the healthy elbow was 8.5º (range 4º–13º). No lateral cortex prominence was recorded. An average of 27.5º (range 15º–35º) of hyperextension of the distal fragment was recorded immediately postoperatively in four patients; however, during postoperative follow-up, the hyperextension was corrected spontaneously in all patients.

Conclusions:

As described by French, osteotomy has the ability to correct the varus deformity only in the coronal plane. However, our research supports the assumption that hyperextension in the sagittal plane might be corrected spontaneously.
