Abstract

Introduction: A variety of fracture patterns are seen in supracondylar humerus fractures in children and these are well described by Bahk et al. Currently followed treatment protocol doesn't recognize these common fracture patterns and pin placement is done at the discretion of the treating surgeon. The aim of the study is to evaluate the usefulness of Bahk classification system in deciding the pin configuration for the specific fracture patterns and thereby assess the functional outcome in the management of supracondylar fractures in children.

Method: The study was done on 100 children of 2-12 years of age from February 2019 to January 2020. After closed reduction under general anesthesia, fractures were classified and pin configuration was decided according to Bahk classification. In the follow-up, patients were assessed for clinicoradiological outcomes based on Modified Flynn's criteria, Baumann angle, and anterior humeral line.

Results: In our study Typical transverse and low sagittal fracture were the most common fracture patterns. In the final follow up as per Flynn's criteria, 93% of the patients showed excellent results. Mean Baumann's angle was not significantly different from the uninjured side and anterior humeral line passed through anterior or middle third of the capitulum in 95% patients.

Conclusion: Using pin configuration suitable to fracture pattern as per Bahk classification improves functional outcome in supracondylar humerus fractures in children and minimizes complications.

Keywords: Anterior humeral line; Bahk classification; Baumann angle; Flynn criteria; Supracondylar humerus.
