[The results of digital replantations at the level of the distal interphalangeal joint and the distal phalanx].
OBJECTIVE
We retrospectively evaluated replantations performed for distal amputations.


METHODS
The study included 82 patients (75 males, 7 females; mean age 29 years; range 10 to 52 years) who underwent replantations distal to the distal interphalangeal joint for a total of 98 amputations. According to the Tamai classification, there were 58 zone 1 and 40 zone 2 amputations. Local digital anesthesia was used in 77 patients (93.9%). Arterial anastomosis was accomplished after bone fixation, and venous anastomosis and nerve repair were performed whenever possible. When venous anastomosis was not possible or in case of venous insufficiency, venous decompression was performed with heparinized gauze placed on the bleeding nail matrix. Functional results and the degree of patients' satisfaction with the cosmetic outcome were evaluated. The mean follow-up was 16 months (range 3 to 46 months).


RESULTS
Replantation was successful in 60 amputations (61.2%) and unsuccessful in 38 cases (38.8%). In successful cases, cosmetic results were satisfactory due to the preservation of the nail and finger length. Functional results were satisfactory in cases in which the distal interphalangeal joint could be preserved. Replantations for zone 1 amputations (74.1%) yielded better results than those performed for zone 2 amputations (42.5%).


CONCLUSIONS
Despite technical difficulties, replantations for distal finger amputations can provide satisfactory functional and cosmetic results.
