Epiphysiodesis in juvenile hallux abducto valgus. A preliminary retrospective study.

Juvenile hallux abducto valgus manifested prior to physeal plate closure was treated by lateral epiphyseal stapling and modified McBride bunionectomy in nine children (15 feet) from 1984 to 1992. The prevalent preoperative symptoms were significantly reduced postoperatively. The intermetatarsal angle decreased an average of 6.6 degrees (initial decrease was 2.7 degrees with an additional 3.9 degrees occurring over time). The hallux abducto valgus angle decreased an average of 19.6 degrees (initial decrease was 10.7 degrees with an additional 8.9 degrees occurring over time).
