Amputation at the proximal phalanx or at the metacarpophalangeal joint can be treated by pollicization of a finger, osteoplastic reconstruction, free microvascular transfer of a toe, or distraction lengthening. The best technique to use to treat these cases depends on the place of amputation and the patient's age, sex, occupation and functional demands. In the past 6 years, we treated 4 patients by lengthening the thumb metacarpal ray and adding a mini wraparound flap from the great toe. All the subjects were female with an average age of 22 years. All 4 patients had sustained traumatic amputations: 2 at the metacarpophalangeal joint and 2 at the base of the proximal phalanx. Distraction was completed approximately 65 days after osteotomy, obtaining an average lengthening of 23 mm. To achieve bone consolidation, the lengthener was left in place for 127 days on average. Microsurgical thumb reconstruction was performed around 3 months after consolidation of the osteotomy. There were no failures or cases of postoperative vascular compromise. The average pinch power was 66% of the opposite hand. The static 2-point discrimination of the reconstructed thumb was 8 mm (range, 7-10 mm). All patients reported being satisfied with the treatment, although 1 patient was partially dissatisfied due to the prolonged length of the treatment. Donor site morbidity was minimal. This procedure is mainly chosen by selected patients who refuse standard microsurgical thumb reconstruction because it requires a longer treatment period. © 2013 American Society for Surgery of the Hand.
