Galeazzi Fracture Dislocation: Clinical Features, Treatment and Complications
Galeazzi fracture dislocation is a fracture of the middle to distal radius associated with a subluxation or dislocation of the distal radioulnar joint
Galeazzi fractures are much more common than Monteggia fractures, Galeazzi account for 7% of all forearm fractures in adults
Radius fractures occurring closer to the wrist are associated with greater instability of the DRUJ
Mechanism of injury
Caused by a fall on the outstretched hand with extended wrist and pronated forearm and a rotational force applied to the body
They also could occur from sports injuries and motor vehicle accidents
Clinical features
Symptoms
Patient present with pain in the forearm and wrist
Physical examination
Look
Look for Swelling, contusions and lacerations
Deformity of the radius or wrist might be obvious
Inspect the lacerations for any evidence of open fracture
Feel
Feel for tenderness over the forearm and wrist
Neurovascular examination is done to look for nerve/vessel injury (esp. median and radial nerves), inquire about weakness, numbness, paresthesia and motor examination
Move
Patient refuse movement due to pain
Examination is repeated multiple times to exclude compartment syndrome
Imaging
X-ray radiographs (forearm AP and lateral) should be ordered and they are enough for diagnosis
A transverse or oblique fracture is seen in the radius with angulation or shortening,
DRUJ is disrupted, signs include:
- Widening of DRUJ on AP
- Dorsal displacement of the ulna on the lateral view
- Ulnar styloid fracture
- Radial shortening greater than 5 mm

Note
The distal radioulnar joint could be injured with isolated radial fracture at any level, or in both forearm bones fractures
Emergency management
Pain management
Gross forearm deformity should be reduced in the emergency department under procedural sedation
Above elbow backslab is applied to support the fracture and prevent rotation
Reassessment of neurovascular status is done
Definitive management
Same as Monteggia, it is important to restore the length of the broken bone
In children, closed reduction is often successful, but in adults closed reduction lead to poor outcomes
That is why in adults, reduction is best achieved by ORIF and plating of the radius and the DRUJ is re examined and re imaged to ensure it is reduced
If the DRUJ is reduced and stable on full range of movement, no further management is needed
If the DRUJ is reduced but unstable then the forearm should be immobilized in the position of stability for the DRUJ (usually supination); K wires maybe applied to support the joint
If the DRUJ is irreducible by closed reduction then open reduction is needed to remove soft tissue interposition or fracture fragment preventing reduction; the triangular fibrocartilage complex and dorsal capsule are then carefully repaired, if there is associated ulnar styloid fracture then it has to be repaired by ORIF
After reduction in all cases, above elbow casting in supination is done for 6 weeks , exercises started as soon as possible
Complications
Early
- Vascular injury
- Nerve injury
- Compartment syndrome: especially in high energy injuries
- Muscle tendon entrapment: make reduction difficult
Late
- Malunion
- Non union
- Radioulnar synostosis
- Elbow stiffness
