Supracondylar humerus fractures in children caused by monkey bar-related injuries: a comparative study.

Abstract

We evaluated the functional and radiological outcomes of surgically treated supracondylar humerus fractures based on injury mechanisms, as well as the therapeutic and prognostic aspects of monkey bar-related injuries, in this study. Between December 2014 and December 2018, pediatric patients who had undergone surgical treatment for supracondylar humerus fractures were analyzed retrospectively. According to the mechanism of injury, patients were divided into two groups: monkey bar-related injuries and other injuries. Patients were evaluated functionally using the Mayo elbow performance score, while radiographically using the anterior humeral line, humero-capitellar angle, and Baumann angle. This study enrolled a total of 50 patients, 27 females and 23 males. Each patient was followed for a minimum of 24 months. There were no significant differences in age, sex or complications between the groups. The Mayo elbow performance score and fracture types were shown to be significantly associated with injury mechanisms ( P = 0.017, P < 0.001). Additionally, a significant correlation between the necessity for open reduction and the mechanism of injury was found ( P = 0.038). There were no significant differences in radiological evaluation between the groups. Supracondylar humerus fractures caused by falling from the monkey bar were more severe in children than supracondylar humerus fractures caused by other mechanisms of injury, and surgical treatment outcomes were worse for supracondylar humerus fractures caused by falling from the monkey bar.
