Distal Thumb Reconstruction with a Great Toe PartialNail Preserving Transfer Technique

The great toe partialnail preserving transfer technique is another modification for distal thumb reconstruction in composite defects at or below the interphalangeal joint of the thumb. Noting the size difference of the nail width between the great toe and thumb, the authors dissected only a thumb nail width and skin flap from the great toe, leaving the remainder of the medial skin flap and nail of the great toe at the donor site. A total of 25 cases between 1993 and 1996 were performed using this technique, and the mean followup period was more than 12 months. The reconstructed thumb had a better cosmesis with a more natural appearance. At longterm followup, the thumb nail width decreased an average of 1.8 mm, but the pulp volume was almost the same as that of the normal contralateral side. The average static 2point discrimination was less than 9.0 mm. In cases with preserved interphalangeal joint, an average of 48 degrees of range of motion with keypinch of 80 percent of that of the normal contralateral thumb was achieved. The final appearance of the donor site with partial nail looks like a brachymetatarsia. Plast. Reconstr. Surg.101 114, 1998.
