A rare combination of an ulnar fracture with posterior dislocation of the head of the radius and fracture of the radius shaft concomitant with an ipsilateral scaphoid fracture is presented. To the best of our knowledge, no such case has been reported. The mechanism of this fracture combination is discussed with respect to its role in producing the Monteggia type II fracture. Treatment consisted...

INTRODUCTION Traumatic dislocation of the radial head in paediatric population is a well described injury, it is usually associated with an injury to the ulna in the Monteggia lesion (1), but can occur as an isolated injury also (2,3). CASE REPORT A 4.5 year old girl presented to emergency department with her right upper limb held in pronation and flexion following isolated closed injury. Roe...

UNLABELLED Dislocation of the head of the radius may be either congenital, an isolated injury or more commonly part of a complex injury to the elbow such as the Monteggia fracturedislocation. Isolated traumatic radial head dislocation without associated injuries in children is a rare and easily missed condition. We report such a case in a 7-year-old boy without any associated injuries or co-mor...

We illustrate a rare complex dislocation of the elbow involving a posterior ulno-humeral dislocation associated with open diaphyseal fracture of the ulna, radial shaft fracture, Type 1 coronoid fracture and neuropraxia of the deep branch of the radial nerve. The isolated ulno-humeral dislocation without radio-capitellar involvement, and ulnar diaphyseal fracture, makes this "reverse Monteggia" ...

A one-year-old neutered male cat was referred for a grade IIIA open radius and ulna fracture. The mid-diaphyseal radial and ulnar fractures were associated with lateral radio-humeral and radio-ulnar dislocations. From these abnormalities, a diagnosis of type IV Monteggia fracture was made. The annular ligament was found to be intact on examination and the radial head was correctly positioned an...

There are two varieties of the fracture-dislocation originally described by Monteggia (1814), according to whether the head of the radius is dislocated anteriorly or posteriorly. The anterior variety, which is the more common, has received a prominent place in all text-books on fractures, chiefly on account of the frequency with which the dislocation is overlooked (Speed and Boyd 1940, \\‘atson...

INTRODUCTION The eponym "Monteggia fracture" includes various patterns of complex fracture-dislocations of the proximal ulna and radius, which are not well defined yet. They are frequently described as Monteggia-like lesions or Monteggia equivalent injuries. Until today, these injury patterns have been reported rarely. The objective of this retrospective study was to better define patterns of i...
