Monteggia and Galeazzi Fractures

A 28-year-old female presents with a fracture of the distal third of the radius with dorsal angulation and an associated dislocation of the distal radioulnar joint (DRUJ). Neurovascular examination is normal. After initial closed reduction and immobilization in a long-arm cast, repeat X-rays at 1 week show loss of reduction with re-angulation of the radius fracture and DRUJ subluxation. What is the most appropriate next step in management?

A 35-year-old woman with a Monteggia fracture (proximal radius fracture with anterior radial head dislocation) is compared to a 40-year-old man with a Galeazzi fracture (distal radius fracture with dorsal ulnar head dislocation). Which radiological finding is the most reliable way to differentiate these two injuries on anteroposterior and lateral forearm radiographs?

A 28-year-old female falls on her extended right wrist while rollerblading. She presents with pain and swelling over the dorsal aspect of the distal forearm. On examination, there is loss of pronation and a prominence over the dorsal wrist. X-rays reveal a fracture of the distal third of the radius with dorsal displacement, and the distal radioulnar joint (DRUJ) appears widened on the AP view. What is the most appropriate initial management?

A 35-year-old female presents 4 hours after a fall on an outstretched hand with dorsal wrist pain and swelling. X-rays reveal a fracture of the distal radius with dorsal angulation and a posterior dislocation of the distal radioulnar joint (DRUJ). There is no associated ulnar fracture. What is the most appropriate next step in management?

A 35-year-old man presents to the emergency department after a fall on an outstretched hand while playing cricket. Radiographs reveal a fracture of the proximal third of the radius with an anterior dislocation of the radial head. What is the most common mechanism of injury in Monteggia fractures?
