Abstract：Objective To evaluate the efficacy of lateral divergent or parallel pin fixation using smooth K-wires for the operative management of Gartland type Ⅲ supracondylar humerus fractures in children. Methods A retrospective analysis of 138 cases of Gartland type Ⅲ supracondylar humeral fractures treated in Beijing Children’s Hospital between February 2017 to February 2019 was conducted. According to fixation methods, the patients were divided into the lateral divergent pin fixation group and the lateral parallel pin fixation group. The clinical features of the two groups and Flynn scores at the last follow-up were compared and analyzed statistically. Results A total of 134 patients were followed up for 6-24 months (mean 16 months). There was no significant difference in clinical characteristics between the two groups. Postoperative evaluation was conducted by Flynn standards. By Flynn’s function standard, the excellent and good rate of parallel group was 93.7%, compared to 90.3% in the divergent group, with no statistically significant difference. By Flynn’s aesthetic standards, the excellent and good rate of the parallel group was 92.1%, and that of the divergent group was 90.1%, so there was no significant difference between the two groups. There were no complications, such as fracture redisplacement, latrogenic nerve injury or cubitus varus. Conclusions Our series demonstrates that both lateral divergent and parallel pin fixations are effective and safe approaches to Gartland type Ⅲ supracondylar humerus fractures in children.
