An unusual Monteggia equivalent type 1 lesion: Diaphyseal ulna and radius fractures with a posterior elbow dislocation in a child / 中华创伤杂志(英文版)

In this report, we describe an extremely unusual Monteggia equivalent type 1 lesion in a 10-year-old boy following a fall from a height of 1 m. On the plain radiographs, our patient had a particular Monteggia equivalent type 1 injury associating a posterior elbow dislocation with diaphyseal radius and ulna fractures. The patient was treated by closed reduction technique. At six months of follow-up, the fractures were consolidated and the elbow was stable. To our knowledge, only 8 adult cases and one paediatric observation with similar lesions had been reported through medical literature. Therefore, the aim of our case report is to remind this rare entity and also to provide a comprehensive review of the literature related to this uncommon lesion.

Missed Variation of the Essex-Lopresti Injury Associated with Type-I Monteggia Equivalent Lesion: A Case Report

The authors report the case of a patient with the combination of a Type I Monteggia equivalent lesion and Essex-Lopresti injury. This combination of injury is very rare, and an associated distal radioulnar injury is often missed. We hope our experience illustrates the need to examine the wrist joint carefully and to be aware of the potential for distal radioulnar joint instability in all patients with type I Monteggia equivalent lesions.

Type III Monteggia Equivalent Fracture with Ipsilateral Distal Radial Epiphyseal and Ulnar Metaphyseal Fracture in a Child: Case Report / 대한정형외과학회잡지

This paper present a rare case of a Type III Monteggia equivalent fracture with an ipsilateral distal radial epiphyseal (Salter-Harris type II) and an ulnar metaphyseal fracture in a child. An 8-year-old boy sustained a closed bipolar fracture of his forearm after a fall from a height. The closed reduction was unsuccessful. Therefore, an open reduction and plate fixation was performed for a diaphyseal fracture of the ulna, and the unstable radial fractures and the distal ulnar metaphyseal fracture were treated with a closed reduction and internal fixation using Kirschner wires (K-wires). Two years after surgery, the joint motion including the forearm, wrist and elbow were completely normal. Radiologically, the bone was well united without any residual deformity.
