[Finger reconstruction by microvascular second toe-to-finger transplantation in patients with traumatic loss of all fingers].
OBJECTIVE
To assess the utility of second toe-to-finger transplantation with neurovascular reconstruction in patients with loss of all four digits.


METHODS
Analysis of 24 toe-to-finger transplantations in 18 patients regarding over-all survival, complications and secondary procedures, sensibility, function, foot symptoms, and patient satisfaction. The original metacarpophalangeal joint was preserved in 50 % of the transplantations. In six patients, a second transplantation was performed.


RESULTS
A mean follow-up of 5.8 years was available in 94 % of the patients. 92 % of the transplanted toes survived, in 38 % of the cases complications occurred followed by a secondary procedure. Two-point-sensibility was present in 62 % of the transplantations, the largest range of motion of ca. 50 degrees was obtained in the metacarpophalangeal joint. An increase in the range of motion could be achieved by preservation of the original finger joint. The mean extension lag was 37 degrees independent of the preservation of the metacarpophalangeal joint. Foot symptoms were mild in four patients, in two cases severe donor-site-problems were observed. Cold intolerance was present in 47 % of the transferred toes. Overall patient satisfaction was high with 83 % of the patients confirming their decision to undergo operative treatment.


CONCLUSIONS
Second toe-to-finger transplantation is indicated in patients with traumatic loss of all digits. By this method, a great functional gain could be achieved as well as a high level of satisfaction. The rate of complications and possible foot symptoms should be considered. The preservation of the original metacarpophalangeal joint seems to be of importance for the function of the transplanted toe.
