Equivalent lesions of Monteggia type IV injury have not appeared so far in the literature. Two Monteggia type IV equivalent lesions, which included a fracture of the radial head associated with midshaft fractures of the radius and ulna in a 3- and in a 12-year-old girl, are reported. The lesion presented in this report could be considered as a missing piece in the puzzle of Monteggia and equiva...

Radial head dislocation associated with plastic bowing of the ulna is classified as a Monteggia equivalent lesion. This injury in children can be treated by closed reduction, but manipulative reduction may not completely correct plastic bowing of the ulna. We encountered two cases of incomplete reduction in which the radial head was reduced in a supination position, but redislocated during rota...

AbsractAll perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. The most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. The reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. Concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

Simultaneous ipsilateral distal and proximal fractures of the forearm are rare [1-3]. There have been case reports describing an olecranon fracture associated with an ipsilateral distal radius epiphyseal injury[1], a Monteggia lesion with an associated ipsilateral distal radius epiphyseal injury[4] or associated with ipsilateral distal radius and ulna metaphyseal fractures[5, 6]. Furthermore, t...

Background: Prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studiedyet so, this study aims to study the recurrent shoulder dislocation following tramadol induced seizure. Methods: In this cross-sectional study, 205 patients with recurrent shoulder dislocation complaints (2 or more) referred to Shafa Orthopedic and Iranmehr hospitals Tehran, Iran, from Oc...

BACKGROUND The pathogenesis of Monteggia injuries remains controversial. The current study biomechanically explored the pathological changes during Monteggia fractures using finite element analysis. METHODS Two cadaveric forearm specimens underwent computed tomography in both the prone and supine positions. The images were imported to Mimics to construct three-dimensional images. The obtained...

A six-year-old girl sustained a Monteggia type-I equivalent fracture of the right forearm. We describe the method of treatment of this rare fracture and its outcome.
