Posteromedial elbow dislocation associated with external condyle fracture in children. Presentation of three clinical cases
Abstract
Introduction: Traumatic posteromedial elbow dislocations associated with external condyle fractures constitute a rare injury in orthopedic pathology. They can go unnoticed if there is no clinical suspicion, and failure in diagnosis and treatment can lead to a poor functional prognosis for the injured limb.
Methods: Between 2020 and 2022, we identified 3 pediatric patients with posteromedial elbow dislocation associated with an external condyle fracture. The three patients presented type 2 external condyle fracture of the Milch classification. All patients were treated surgically. A 2-year follow-up was carried out, except in one of them. A clinical and radiological follow-up was performed to evaluate the injury. The DASH questionnaire was administered to the 3 patients.
Results: Excellent results were obtained in 2 of the patients and a good result in one of them due to a loss of extension of 15 degrees. Although everyone had a good DASH functional questionnaire.
Conclusion: Elbow dislocation associated with lateral condyle fracture is a rare injury. It is necessary to make an early diagnosis through a correct study of the injury, whether with x-rays, arthrography, tomography or magnetic resonance imaging. Good results can be achieved as long as correct treatment is carried out with exhaustive evolutionary control.
