Galeazzi fracture-dislocation fixation is an operation to fix a fracture of the radius combined with disruption of the distal radioulnar joint (DRUJ). The radius fracture is fixed with a plate, and the DRUJ stability is assessed.
An incision is made over the anterior (Henry) approach to the radius. The radius fracture is anatomically reduced and fixed with a plate and screws. The DRUJ is then tested for stability. If stable after radius fixation, no further intervention is needed. If unstable, the DRUJ may be pinned with a K-wire in a reduced position, or the TFCC may be repaired. The operation takes one to one and a half hours.
All Galeazzi fracture-dislocations in adults require surgery. Without accurate radius fixation, the DRUJ remains disrupted, causing chronic wrist instability and pain with forearm rotation.
Not appropriate in adults. Surgical fixation is the standard treatment.
X-rays of the full forearm and wrist. CT may be used to assess the DRUJ.
Restoration of radius length and alignment with stable DRUJ. Good outcomes when treated promptly.
Some loss of pronation or supination.
Residual clicking or discomfort at the wrist.
May require further surgery.
Radius fracture failing to heal.
Superficial radial nerve or posterior interosseous nerve.
Wound infection.
General or regional anaesthesia.
Splint for two to four weeks (longer if DRUJ pinned). K-wire removal at six weeks if used. Active forearm rotation exercises. Full recovery three to six months.
X-rays at two weeks, six weeks, and three months.
The distal radioulnar joint is where the radius and ulna bones meet at the wrist. It allows the forearm to rotate (pronation and supination). Disruption causes pain and instability with turning movements like opening a door or using a screwdriver.
