How long does a Monteggia fracture take to heal?
Children have little trouble regaining motion lost through stiffness, despite immobilization of the fractures for the duration of the initial healing period (3-6 weeks) The potential may exist for remodeling of mild residual angular deformities (< 10°)
What is a Monteggia variant fracture?
Introduction. Monteggia fracture is a combination of fracture of proximal ulnar shaft associated with radial head dislocation (proximal radio-ulnar joint subluxation or dislocation). Such an injury is not common among children but may be challenging and lead to serious complications if not treated in acute stage.
How do you fix a broken Monteggia?
For Monteggia fracture-dislocations, best treatment includes ORIF of the ulna diaphyseal fracture. The ulna fracture is approached and reduced first. The radial head dislocation then usually reduces indirectly and is stable. (More than 90% of radial head dislocations are stable after fixation of the ulna.)
What are Monteggia variants?
Purpose: Monteggia variant defined as Monteggia fracture dislocation with radial head or neck fracture, coronoid fracture, ulnohumeral joint dislocation or combination of these injuries.
How does a Monteggia fracture happen?
Monteggia fractures are primarily associated with falls on an outstretched hand with forced pronation. If the elbow is flexed, the chance of a type II or III lesion is greater. In some cases, a direct blow to the forearm can produce similar injuries.
What causes Monteggia fracture?
How common is Monteggia fracture?
Monteggia fractures account for approximately 1% to 2% of all forearm fractures. Distal forearm fractures are far more frequent than midshaft forearm fractures, which occur in about 1 to 10 per 10,000 people per year.
How do you remember monteggia?
GRUesome MURder assists remembering which bone is firstly fractured and then secondly which is dislocated:
- G: Galeazzi R: radius fracture U: ulna dislocation.
- M: Monteggia U: ulna fracture R: radial head dislocation.
What is difference between monteggia and Galeazzi fracture-dislocation?
Monteggia fractures and Monteggia variants are fractures of the proximal 1/3 ulna with concomitant proximal radioulnar joint (PRUJ) disruption (evident by radiocapitellar subluxation or dislocation). Galeazzi fractures are fractures of the radial shaft with concomitant dislocation of the distal radioulnar joint (DRUJ).
What is Monteggia fracture-dislocation?
Monteggia fracture-dislocations consist of a fracture of the ulnar shaft with concomitant dislocation of the radial head. The ulnar fracture is usually obvious, whereas the radial head dislocation can be overlooked, with potentially serious functional and medico-legal ramifications.
What is the difference between ulnar fracture and Monteggia fracture?
The ulnar fracture is usually obvious, whereas the radial head dislocation can be overlooked, with potentially serious functional and medico-legal ramifications. Typically, Monteggia fracture-dislocations occur as the result of a fall onto an outstretched hand (FOOSH) 4.
What are the treatment options for Monteggia fractures?
Historically, nonsurgical treatment methods were recommended for adults; however, the emphasis is now placed on early surgical repair of most Monteggia fractures ( 62 ). Recent reports have shown improved outcomes after surgical intervention ( 62 – 64 ), with prompt detection of these injuries allowing appropriate early intervention.
Which radiographs are characteristic of a Mason-Johnston type I neck fracture?
Oblique (a) and lateral (b) radiographs of the elbow demonstrate a nondisplaced radial neck fracture with anterior and posterior fat pad elevation (black arrows in b ), findings indicative of a Mason-Johnston type I injury.
