Second toe transplantation to reconstruct digits.
In congenital absence of fingers or in post-traumatic amputations of the thumb or fingers, reconstruction by microsurgical toe-to-hand transfer is becoming a common treatment for these difficult problems. In case of congenital absence of the thumb, fingers, or both, these transfers can provide acceptable growth, function and sensation of the transferred toes with a current success rate usually greater than 95%. The most commonly transplanted toe is the second toe, since it is the longest toe and combines all the useful characteristics of a finger (such as joint, a nail, sensitive pulp tissue, and the ability to growth) with a good reliable blood supply. In this article, we discuss the rationale for this treatment approach, by considering the indications to treatment, the patient's preoperatory assessment, and the long-term results. We also report a case of a 4-year-old female child, suffering from congenital partial absence of second finger of the left hand, who underwent reconstruction by transfer of the second toes of foot.
