[Double toe to hand transfer in children with symbrachydactyly]

Symbrachydactyly is fairly frequent congenital malformation that appears during first weeks of pregnancy. The range of clinical presentations goes from hypoplastic fingers to true agenesis. Although it usually appears in a random fashion, sometimes it is associated to other systemic malformations.

The aim of this study is to check the functional, cosmetic and psychological results of those patients affected of grade IV symbrachydactyly treated using a double second toe transfer. The method employed is a retrospective study of the clinical records from 6 patients (5 males and 1 female) operated in our Department during the last five years. The follow up period was from 3 months to five years.

Transfer from the second toe to the first ray was performed during the first surgical period, while transfer to the fourth ray was done in a second procedure. The mean age for the first operation was 19 months, and 30 months for the second one. There were no flap failure or major surgical complications. Tenolysis and tenoplasty was done in two patients to improve flap function and position. Motion rehabilitation was installed during the postoperative period. Functional, opposing pinch, and cosmetic results were satisfactory. Parents "and patients" psychological acceptance was also good. No walk disturbance was observed.

Double second toe to hand transfer is a good option for the symbrachydactyly treatment in cases of thumb agenesis. Rehabilitation is the key clue for functional recovery. Surgery improves social and family relationships.
