Objective  To explore the effect of free rasceta with vascular anastomosis combined with tissue flap repair in treating patients with replantation of severed finger without shortening.

  Methods  Totally 68 patients with severed fingers were selected and divided into two groups according to the therapeutic plan, with 34 cases in each group. The control group was treated with conventional replantation of severed finger by shortening phalanges, while the observation group was treated with replantation of severed finger without shortening by combination of free rasceta with vascular anastomosis and tissue flap repair. The excellent and good rate of treatment, hospitalization time, total recovery time, patients′satisfaction degree to finger shape and score of quality of life were compared between the two groups.

  Results  The excellent and good rate of the observation group was 91.18%, which was significantly higher than 70.59% of the control group (P < 0.05). The hospitalization time and total recovery time of the observation group were significantly shorter than those of the control group (P < 0.05). The satisfaction degree to finger shape in observation group was 94.12%, which was significantly higher than 73.53% in control group (P < 0.05). The scores of physiological function, social function, vitality and physiological function in the observation group were significantly higher than those in the control group at 3 months after treatment (P < 0.05).

  Conclusion  For patients with replantation of severed finger without shortening, free rasceta with vascular anastomosis combined with tissue flap repair can obviously increase the excellent and good rate of treatment, accelerate the process of rehabilitation and improve the quality of life.
