GALEAZZI FRACTURE- DISLOCATION
Galeazzi Fracture-dislocation
- Defined as fracture of the distal third of radius with dislocation or subluxation of distal radio-ulnar joint.
- Mechanism of injury : Fall on out-stretched hand.
Clinical features
- Prominence and tenderness over the ulnar styloid process.
- Piano-key sign : The distal third of radius is ballotable
- Instability of the distal radio-ulnar joint can be made prominent by supination and pronation of forearm.
- Can be complicated as ulnar nerve injury (resulting in Ulnar claw hand)
Radiological features
- Transverse of oblique fracture of the distal third of radius.
- Dorsal displacement of the distal ulna or the distal radio-ulnar joint.
Complications
- Main complication is mal-union, which limits supination and pronation of the forearm.
Treatment
- Close reduction is not done (unless in children), since this fracture is unstable.
- Instead, open reduction and internal fixation is done.
Exam Important
- Galeazzi fracture is fracture of the distal third of the radius with dislocation of the distal radio-ulnar joint.
- Galeazzi fracture is fracture of Lower end of radius.
- Galeazzi fracture is Fracture of the distal radius with inferior radio ulnar joint dislocation.
- Fracture distal 1/3 radius with DRUJ subluxation.
