Lateral Humeral Condyle Fracture in Childhood: Results of a New Surgical Technique

TL;DR

A new surgical technique for treating lateral humeral condyle fractures in children shows good healing and functional outcomes with minimal complications.

Contribution

A novel surgical technique using trans-bone suture with resorbable threads is proposed and evaluated for treating lateral condyle fractures in children.

Findings

Radiological healing was achieved in all 36 patients treated with the new surgical technique.

Only one complication occurred, and no additional surgeries were needed.

Most patients achieved full elbow flexion of 110 degrees or more and complete extension.

Abstract

Fractures of the lateral condyle of the humerus are one of the most common fractures in children, accounting for between 10% and 20% of fractures involving the elbow, with a peak incidence at 6 years of age. Treatment is often surgical for displaced fractures > 2 mm, according to Milch and Jakob classification. There is no consensus in the literature about the appropriate surgical management of these fractures. Objectives: The aim of this study is to describe, propose, and evaluate outcomes and complications of the surgical technique of reduction and osteosynthesis using trans-bone suture with resorbable threads. Methods: Patients with lateral condyle fractures treated with this surgical technique from 2015 to 2019 were included in this retrospective study, with a minimum follow-up of 24 months. For clinical and functional assessment of the elbow, Mayo Elbow Scores were recorded; we assessed the time of fracture healing, carrying angles, and Baumann angle of the affected limb compared to the healthy contralateral elbow for radiographic data. Complications have also been described. Results: We achieved satisfactory results; 36 patients with lateral condyle fractures were included in this study. Radiological healing was achieved in all cases. There was only one complication. No cases required additional surgical procedures. Almost all patients achieved a complete flexion of 110 degrees or more and complete extension. Conclusions: This surgical technique has good functional outcomes and fracture healing, a lower incidence of complications when compared to other surgical techniques, and no mechanical failure with good clinical and radiological results.
