Objective:To investigate the clinical effect of the proximal interphalangeal kite flap in repairing the wound of the posterior web of the split toe.Methods:A retrospective case series study was used to analyze the clinical data of children with syndactyly after toe web wounds were repaired with proximal kite flap between toe webs in the Yidu Central Hospital of Weifang from May 2010 to March 2019. The satisfaction of flap repair effect (the total score is 5-10) and the operation effect according to toe function, toe web slope, and depth were evaluated. The measurement data of normal distribution were expressed in Mean±SD and analyzed by paired sample t-test. Results:A total of 10 children with syndactyly were included, including four males and six females, aged from 6 months to 9 years. Seven cases were on the right side, and there were on the left. All were soft tissue connexions, incomplete syndactyly 6 feet, complete syndactyly 4 feet. All flaps survived and were followed up for an average of 13 months (range, 6-24 months). The score of satisfaction was 8.6±2.7. The appearance, color, elasticity, and texture of the reconstructed web are similar to those of the uninjured side. At the last follow-up, there was no significant difference between the abduction of the separated toe and that of the healthy side (43.57 ± 3.82)° and (44.39 ± 4.25)°( P=0.64). There was no significant difference between the two groups ( P=0.66). The reconstruction depth of the toe web was (1.19 ± 0.23) cm, which was not significantly different from that of the healthy side (1.21 ± 0.27) cm ( P=0.85). Conclusions:The proximal interphalangeal kite flap is one of the ideal methods to repair the wounds of the posterior web of the congenital syndactyly. However, the number of cases in this study is small, and the follow-up time is short. The curative effect of the children with the growth and development process needs further research.
