Abstract

Abstract : Background: Complex fracture-dislocations of the elbow, including terrible triad of the elbow, are serious injuries with guarded outcomes in adults. Although described extensively in adults, little is known about similar complex fracture-dislocations of the elbow in the pediatric population. The purpose of this study was to describe patterns of elbow dislocations with associated fractures in children and report the outcomes of these injuries. Methods: This was a retrospective review of patients who presented to a level I trauma center from 2007 to 2019 with an elbow dislocation and at least 2 associated fractures. Demographic data, fracture locations, and treatment modality were recorded. Operative reports and radiographs were reviewed to determine clinical outcomes and complications. Results: A total of 26 patients (mean age, 9.8 y) were identified. The majority of patients sustained an elbow dislocation and a medial epicondyle fracture (n=16). The most common third fractures involved the lateral condyle (n=8) or radial neck (n=7). At mean 6.03±3.11 months follow-up, 3 patients lacked ≥10 degrees of extension, and 2 patients lacked ≥15 degrees of flexion. Most patients had a Flynn score of "excellent" (n=20, 76.9%) or "good" (n=2, 7.7%). One patient with significant residual stiffness (>30 degrees flexion contracture) eventually underwent open contracture release. Conclusions: The most common complex elbow fracture-dislocation pattern in this series was an elbow dislocation with fracture of the medial epicondyle and lateral condyle or radial neck. In contrast to adult terrible triad injuries, most patients had a favorable clinical outcome, with nearly 80% excellent results and a low rate of complications. Level of Evidence: Therapeutic Level IV—case series. Abstract : Supplemental Digital Content is available in the text.
