A Novel Variant of Type II Monteggia Equivalent Fracture-Dislocation in Children: A Case Report

Abstract

Monteggia fracture-dislocations are extremely rare in children. By definition, it is an ulnar shaft fracture with proximal radioulnar joint dislocation. Throughout the years, various equivalents of this entity have been described. In this report, we present a unique case of a type II Monteggia fracture equivalent with an ipsilateral fracture of the proximal radius and olecranon in a child. The patient was a 12-year-old male who presented with a history of a fall on an outstretched hand. The diagnosis was made based on the clinical examination and plain radiographs. We describe the management of this unique fracture and discuss the possible mechanism of injury. We have highlighted a rare combination of injuries. It is crucial to investigate the condition properly in order to avoid missing the diagnosis and to prevent poor outcomes and further unnecessary revision surgeries.

CORHD Lesions: A New Pediatric Terrible Triad of the Elbow. A Case Report and Literature Review

“…Other atypical forms of Monteggia type ll fracture-dislocation in children have also been described [46]. In medical practice over time, for more than 50 years, equivalent lesions have not been clearly understood and there is no clear definition of what an equivalent Monteggia lesion would be [47]. The typological classification of Monteggia fractures-dislocations assesses the features and type of the two associated lesions: ulna fracture and dislocation of the proximal end of the radius.…”
