Abstract

The authors successfully performed a series of 32 distal finger reconstructions using partial second toe-to-finger transfers solely for aesthetic indications. The resulting hand function shows an average static 2-point discrimination of 8 mm. Total active range of motion was 205 degrees. Key-pinch strength and grip strength averaged 65 and 90% of the normal contralateral side, respectively. Patient satisfaction, as reflected by the average subjective satisfaction scores for aesthetic appearance and function (SSSAF) of the reconstructed distal finger, was high at 82 and 78, respectively. The SSSAF for the donor site averaged 88 for function and 75-80 for aesthetic appearance, which is statistically significant (p<0.05). The authors modified the technique of distal finger reconstruction using second toe transfers in three ways. One is to skeletonize the neurovascular bundle of the harvested toe and pass it through a subcutaneous tunnel between the distal finger incision and the web space incision to avoid lengthy and unsightly scars on the reconstructed finger. Another is to defat the skin flaps developed at the amputated stump and to use a zigzag incision on the toe flap to create a smoother skin junction between the stump and the transferred toe. The third refinement is to perform the arterial microanastomosis at the level of the web space to take advantage of the larger diameter of the vessels in this area. Cosmetic reconstruction of the distal finger with a partial second toe-to-hand transfer provides a high degree of patient satisfaction, both aesthetically and functionally.
