What type of fracture is a Monteggia fracture?

A Monteggia fracture-dislocation refers to dislocation of the radial head (proximal radioulnar joint) with fracture of the ulna….2. How are they classified?

What is Monteggia fracture dislocation?

The Monteggia fracture is a fracture of the proximal third of the ulna with dislocation of the proximal head of the radius. It is named after Giovanni Battista Monteggia.

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 does a Monteggia fracture occur?

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 is Barton’s fracture?

A Barton fracture is a compression injury with a marginal shearing fracture of the distal radius. The most common cause of this injury is a fall on an outstretched, pronated wrist.

Which nerve is damage in Monteggia fracture?

Posterior interosseous nerve palsy is the most common nerve injury in Monteggia fracture-dislocations,. Most of these injuries are neuropraxia and recover slowly after the anatomical reduction of the radial head.

What is the difference between Galeazzi and Monteggia fracture?

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 the difference between Galeazzi and monteggia fracture?

What is a Bennett’s fracture?

Introduction. Bennett fracture is the most common fracture involving the base of the thumb. This fracture refers to an intraarticular fracture that separates the palmar ulnar aspect of the first metacarpal base from the remaining first metacarpal.

What causes Barton’s fracture?

The most common cause of this injury is a fall on an outstretched, pronated wrist. The compressive force travels from the hand and wrist through the articular surface of the radius, resulting in a triangular portion of the distal radius being displaced dorsally along with the carpus.

How would you describe a Monteggia fracture?

A Monteggia fracture is defined as a proximal 1/3 ulna fracture with an associated radial head dislocation.

What is a Galeazzi fracture?

A Galeazzi fracture is a fracture of the middle to distal third of the radius associated with dislocation or subluxation of the distal radioulnar joint (DRUJ).

How is a Monteggia fracture classified as a dislocation?

2. How are they classified? A Monteggia fracture-dislocation refers to dislocation of the radial head (proximal radioulnar joint) with fracture of the ulna. The Bado classification system (Table 1) describes four types. Table 1: Bado classification of Monteggia fracture-dislocations.

When to see an orthopedic specialist for a Monteggia fracture?

If an ulna fracture is present, always look for a radial head dislocation. All Monteggia fracture-dislocations require an urgent orthopedic assessment. Reduction is always required. Delayed or missed diagnosis is the most frequent complication. 2. How are they classified?

Is there an ORIF for a Monteggia fracture?

Treatment can be isolated closed reduction in the pediatric population (if radiocapitellar joint remains stable). Adults and unstable injuries generally require ORIF of the ulna. Please rate this review topic.

Which is the most common type of Monteggia lesion?

Bado Type I A Bado type I lesion is an anterior dislocation of the radial head associated with an apex anterior ulnar diaphyseal fracture at any level. This is the most common Monteggia lesion in children and represents approximately 70% to 75% of all injuries.
