Complications of duplicate thumb reconstruction.

Abstract

Thumb duplication is a common anomaly treated by most hand surgeons. Successful reconstruction of this disorder requires the surgeon to address abnormalities of collateral ligaments, tendon, and bone. With growth, secondary problems may occur, including bony overgrowth, tendon imbalance, and joint stiffness. Surgeons must be aware of these potential complications when the performance of initial surgery and long-term follow-up of the child are necessary.
