Galeazzi Fractures are a type of fracture of the radial shaft which is associated with dislocation of the distal radio-ulnar joint (DRUJ). This particular fracture is name after Ricardo Galeazzi who was an Italian surgeon in Milan. This injury is uncommon and only accounts for about 7% of all forearm fractures in adults.
A radius fracture may be short, oblique, or transverse and involves a fractures at the junction of the middle third and distal third of the radius with associated injury to the distal-ulnar joint. The closer the fracture is to the DRUJ, the more likely that it will be unstable. Dislocation of the DRUJ is usually dorsal. It may be associated with either a ligamentous injury or fracture of the styloid process of the ulna.
A fracture is usually located above the proximal border of the pronator quadratus muscle. The distal fragment usually moves towards the ulna. Galeazzi fractures are best treated with open reduction and internal fixation of the radius and assessment of the distal radio-ulnar joint.
Surgery is necessary. Nonsurgical treatment in adults usually results in recurrent dislocations of the distal ulna and a bad outcome. Surgery is done by a volar plate fixation. Followed by assessment of the Distal Radio Ulnar Joint (DRUJ), if stable, the forearm will be splinted in supination for six weeks. If the joint is unstable, reduce and pin the distal radio-ulnar joint in supination for about four weeks. If the joint is not reducible, open and explore the joint. Check for entrapment of the ECU.
