The effect of two different skin flaps on replantation repair of skin defect type severed fingers and their impact on finger function recovery / 中国医师杂志

ABSTRACT

Objective:To explore the effects of lateral finger flap and micro free venous flap on the replantation repair of skin defect type severed fingers and their impact on finger function recovery.Methods:A retrospective selection was conducted on the clinical data of 94 patients (94 fingers) with skin defect type finger amputation admitted to Affiliated Hospital of Jiangnan University from January 2020 to September 2022. According to the different design methods of the skin flap, there were 48 cases in the observation group (micro free venous flap) and 46 cases in the control group (finger side flap). We compared the repair effects, blood circulation, finger function recovery, and complications between two groups.Results:Two months after surgery, there was no statistically significant difference ( P>0.05) in the total effective rate of repair between the observation group [79.17%(38/48)] and the control group [76.09%(35/46)]. The blood flow velocity, skin temperature, and skin redness ratio of the observation group were higher than those of the control group, and the capillary filling time was shorter than that of the control group, with statistical significance (all P<0.05). There was no statistically significant difference (all P>0.05) in the scores of joint autonomy, daily living activities, and recovery between the two groups. The subjective sensation and appearance scores of the observation group were lower than those of the control group, and the differences were statistically significant (all P<0.05). The incidence of complications in the observation group was 10.42%(5/48), and there was no statistically significant difference ( P>0.05) compared to the incidence of complications in the control group [13.04%(6/46)]. Conclusions:For patients with severed fingers with skin defects, the lateral finger flap and mini free vein flap are effective methods for replantation. In clinical practice, reasonable skin flap repair methods can be flexibly selected based on the patient′s actual situation.
