Objective To explore the value of applying the flat responsibility care model in the surgical treatment of pediatric supracondylar humerus fractures. Methods One hundred and thirty-eight cases of children with supracondylar humerus fractures admitted to a hospital in Zhengzhou from December 2018 to January 2021 were selected and divided into a control group and an experimental group using the random number table method

with 69 cases in each group. All children received surgical treatment

and the children in the control group were treated with conventional care

while the children in the experimental group were treated with flat responsibility care on the basis of the control group. The number of days of hospitalization

fracture healing time

postoperative visual analog scoring（VAS） score

treatment compliance and elbow function before and after the intervention were compared between the two groups. Results The compliance with medication

exercise and reasonable diet scores were higher in the experimental group than in the control group（P<0.05）; the hospitalization days and fracture healing time were shorter in the experimental group than in the control group（P<0.05）; the elbow function scores were higher in the experimental group than in the control group after the intervention（P<0.05）; the incidence of elbow dysfunction in the experimental group was 2.90%（2/69） compared with 5.80%（4/69） in the control group

showing no statistically significant difference（P>0.05）; 2 weeks after surgery

the VAS scores were lower in the experimental group than in the control group（P <0.05）. Conclusion When applied to the surgical treatment of pediatric supracondylar humerus fractures

the flat responsibility care model can help improve the children’s treatment compliance

reduce postoperative pain

improve elbow joint function

and promote recovery of the body.
