Objective To investigate the clinical effect of tongue-shaped flap cut into the triceps and triceps both sides of the road approach road into the way of two surgical treatments of supracondylar fractures in children.Methods 90 patients with pediatric supracondylar fractures were chosen.50 cases of tongue-shaped flap to triceps road cut into were set as A group,40 patients taking brachial three muscles on both sides of the first approach were set as the B group.The clinical effects of the two groups were compared.Results The operative time,blood loss,cast immobilization time in B group was superior to group A ( P ＜ 0.05 ),there was statistically different.The pain score improvement in group B was significantly better than group A before and after treatment(P ＜0.05),the difference was statistically significant.After treatment,A group of patients with excellent results was in 22 cases,good in 24 cases,the fine rate was 92％.B group with excellent results was in 23 cases,good was in 16 cases,the good rate was 97.5％.The superior quality of the treatment effect in B group was better than A group( P ＜ 0.05),the difference was statistically significant.Conclusion The operative time,blood loss,time cast immobilization,pain improvement,the treatment effects for triceps both sides of the approach for the treatment of supracondylar fractures in children are better than the triceps tongue-shaped flap cut into the road,and there is high clinical value.
