摘要：

IntroductionHow to reconstruct the damaged fingertip is a clinical problem. Our team propose the theory of equivalent design and use the mini toenail flap pedicled with the hallux transverse artery and toe pulp vein transplantation technique to reconstruct Allen's type II fingertip injury. Thus, we perform the retrospective study to evaluate the effects of this technique on fingertip injury.Materials and methodsA retrospective analysis was performed on 56 patients admitted to our hospital from January 2015 to January 2020 who used equivalently designed miniature hallux toenail flaps for the plastic repair of fingertip damage. We recorded the size of the miniature hallux toenail flap, operation time, intraoperative blood loss, and complications and calculated the survival rate of the transplanted miniature hallux toenail flap. During routine follow-up after surgery, we recorded nail growth time and observed finger appearance. At the last time of follow-up, we recorded Semmes-Weinstein evaluating tactile sensation and Two-point discrimination testing (TPD). The efficacy was evaluated by Zook score evaluation.ResultsThe size of the mini hallux toenail flap was 0.71 cm x 1.22 cm to 0.88 cm x 1.71 cm. The operation time was (3.54 & PLUSMN; 0.58) hours, the intraoperative blood loss was (20.66 & PLUSMN; 4.87) ml, and the survival rate of mini hallux toenail flaps was 100%. The postoperative follow-up time was (30.82 & PLUSMN; 11.21) months, and the total nail growth time was (9.68 & PLUSMN; 2.11) months. The average tactile sensation evaluated by the Semmes-Weinstein test was (0.32 & PLUSMN; 0.14) g, and the average TPD was (7.33 & PLUSMN; 1.02) mm. According to Zook score, the curative effect of fifty-six cases were all excellent or good with 100% excellent and good rate, and all patients had beautiful appearances and good function of damaged fingertips.ConclusionsBased on the equivalent design theory, the mini hallux toenail flap pedicled with the hallux transverse artery and toe pulp vein transplantation technique is an effective method to reconstruct Allen's type II fingertip injury with a beautiful appearance and good function.
