Internal fixation with mini plate and hollow screw decreases average operation time and blood loss in comparison to Kirschner wire and steel wire suture. a comparison of operative time of patients between four groups; b comparison of intraoperative blood loss of patients between four groups. n = 31 in the mini plate group; n = 44 in the hollow screw group; n = 62 in the Kirschnner wire group; n = 27 in the steel wire suture group; measurement data was presented as mean ± standard deviation; multi-group data was compared using single factor ANOVA; *, vs. the mini plate group, p < 0.05; ^#, vs. the hollow screw group, p < 0.05
