Introduction
There are very few reports on the use of a free composite flap from the toe to repair small tissue defects in the hand. Here, we describe our experience using a free composite flap from the great toe and second toe.
Method
Fifteen patients sought surgical treatment for tissue defects of the hand at our medical institution from July 2008 to December 2010. These defects included: dorsal defect of the distal thumb, dorsal-radialis defect of the proximal thumb, degloving injury of distal index finger, pulp defect of the middle finger and these were repaired with toe side pulp flaps. In five subjects, treatment of the metatarsophalangeal joint (MPJ) or proximal interphalangeal joint (PIPJ) involved a combined extensor tendon defect with a composite flap with MPJs and PIPJs and the extensor tendon of the second toe. All flaps were transferred as free flaps.
Results
All flaps survived. At 34.8 months of follow-up, the average subjective satisfaction score was 8. Eleven patients (73.3 %) experienced cold intolerance, and one patient (6.7 %) dysesthesia. The Semmes–Weinstein Sensitivity Score was 3.48–4.71 at the flap and 0–4.21 at the donor site. The mean two-point discrimination was 7.13 mm. Grip strength was 10 % less than in the unaffected hand. Mobility loss in the MPJ and PIPJ was <10°. No patients had complications at the donor sites.
Conclusion
Based on the unique characteristics of the free flap from toes, we consider them to be good options for reconstruction of small tissue defects in the hand according to various sizes, shapes, and sites.
