Introduction: Monteggia fracture-dislocation refers to traumatic ulnar fractures and dislocation of the radial head, which is one of the most frequently missed injuries, especially in children. The most widespread attitude towards chronic Monteggia lesion is the open reduction of the radial head associated with ulnar osteotomy with or without annular ligament reconstruction. Our study aimed to analyze the risk factors for redislocation after surgical management of chronic Monteggia lesion and the benefits of annular ligament reconstruction and radiocapitellar pinning in paediatric.

Monteggia fracture is characterized by radial head dislocation combined with proximal ulnar fracture. If not diagnosed at an early stage, these lesions can gradually lead to forearm deformities and dysfunction, finally resulting in neglected Monteggia fracture. When the radial head is not reduced, several deformities develop at the humeroradial joint, including cubitus valgus and osteoarthritis. Read More

Introduction: Monteggia fracture-dislocations are rare and complex injuries that usually involve a fracture of the proximal ulna associated with a proximal radioulnar and radiocapitellar joint dislocations. These injuries comprise <1% of all pediatric forearm fractures. We report on a pediatric Monteggia fracture-dislocation variant that included an irreducible divergent ulnohumeral joint dislocation, an irreducible anterior radial head dislocation, and a proximal and distal radius and ulna fracture.

Rationale: Traumatic radial head dislocation (RHD) can occur due to hyperpronation injury with sequential disruption of the annular ligament, quadrate ligament, and the interosseous membrane. Although studies have shown that traumatic RHD is generally associated with Monteggia fracture-dislocation, traumatic RHD occurring with ipsilateral radial shaft fractures has rarely been reported. Delayed RHD secondary to the malunion of isolated radial shaft fractures is extremely rare. Read More

Background: Monteggia fractures are uncommon injuries in paediatric age. Treatment algorithms assert that length-unstable fractures are treated with plate fixation. In this case report, intramedullary fixation of an acute length-unstable Monteggia fracture allowed a stable reduction to be achieved, along with an appropriate ulnar length and alignment as well as radio capitellar reduction despite the fact that the orthopaedic surgeon did not use a plate for the ulnar fracture.

A pulled elbow is a common childhood orthopaedic injury that is usually caused by longitudinal traction on the hand. The pathophysiological mechanism of a pulled elbow involves interposition of the annular ligament into the radiohumeral joint. Recent ultrasonographic studies have shown that both the supinator muscle and annular ligament were trapped into the radiohumeral joint. Read More

Background: Monteggia and equivalent lesions are relatively rare but result in severe injuries in childhood, typically affecting children between 4 and 10 years old. The diagnosis and treatment of an equivalent Monteggia lesion is more complicated than those of a typical Monteggia fracture. This type of lesion may be challenging and may lead to serious complications if not treated properly. Read More

Essex-Lopresti injuries and terrible triad injuries of the elbow are rare injuries that typically result from high-energy trauma such as falling from a height or a motor vehicle collision. However, the combination of an Essex-Lopresti injury and terrible triad injury is unique and poses a significant challenge for treatment as these injuries are independently associated with poor functional outcomes if they are not acutely diagnosed. We describe a case of a 19-year-old who presented with an unusual variant of a terrible triad injury associated with an Essex-Lopresti injury. Read More

Monteggia fractures classically involve a proximal ulna fracture with an associated radial head dislocation. The presence of radial head/neck fracture and comminution of the proximal ulna with coronoid involvement elevates the complexity of surgical reconstruction considerably. The Jupiter classification captures this injury pattern as a subgroup of Bado posterior Monteggia lesions. Read More

The incidence of untreated Monteggia fracture-dislocations is not insignificant. But there is no consensus as to the surgical indication and best surgical technique to use. Single-stage reduction of the radial head through an elbow arthrotomy and ulnar osteotomy is a complex surgical procedure that requires stabilization of the ulnar segments during every step of the intervention.

Abstract: A neglected Monteggia fracture is defined as the fracture of the proximal ulna associated with radial head dislocation (RHD) without undergoing any treatment for 4 weeks or more after injury. One-stage operation of ulnar corrective osteotomy and open reduction of RHD might result in many complications. Therefore, a two-stage strategy, including ulnar osteotomy (UO) with or without annular ligament reconstruction (ALR), was adopted at our institute since 2010. Read More
