Galeazzi and Monteggia Fractures

Galeazzi Fracture: Definition:

-       Fracture of the shaft of radius (most commonly at the junction of the middle and distal thirds) with dislocation of distal radioulnar joint (DRUJ)

Mechanism:

- Direct wrist trauma

- Fall onto outstretched hand with forearm in pronation

Treatment:

-       Operative:

- ORIF of radius with reduction and stabilization of DRUJ. Anatomic reduction of DRUJ is required. Acute  operative treatment far superior to late reconstruction

Complications:

- Compartment syndrome: increased risk with high energy crush injuries

-       Neurovascular injury: uncommon except type III open fractures

 

Monteggia fracture:

Definition:

-       Fracture of the proximal portion of the ulna combined with dislocation of the radial head.

Epidemiology:

-       Rare in adults

-       More common in children with peak incidence between 4 and 10 years of age

Mechanism:

- Fall on an outstretched hand with the forearm in excessive pronation (hyper-pronation injury)

Prognosis:

-       If diagnosis is delayed greater than 2-3 weeks complication rates increase significantly

Treatment:

- Nonoperative

o   Closed reduction 

  • indications
  • more common and successful in children

- Operative

o   ORIF

  • indications
  • acute fractures which are open or unstable
  • comminuted fractures
  • Most Monteggia fractures in adults are treated surgically

o   IM Nailing of the ulna

  • Indications
  • transverse or short oblique fracture

Confusing right? Well... Just Remember "MuGGeR"!!
