1/22/2024 0 Comments Galeazzi fracture mechanismThe ulnar head, distally, serves as an insertion point for the TFCC and supplements distal radioulnar joint. Three main stabilizers of this frame are triangular fibrocartilage distally, interoseous membrane which connects both the bone, and annular ligament which holds the proximal radius. The radius and ulna bones form the bony framework of the forearm. When the radial fracture is more than 7.5 cm from the articular surface, this incidence is 6%.įractures in the proximal two-thirds of the radius are not associated with injury to the distal radioulnar joint. The incidence instability of radial fracture is 55% when the fracture is within 7.5 cm from the articular surface. It is named after surgeon, Riccardo Galeazzi, who described this fracture in 1934 though Cooper was first to describe this injury pattern in 1842. Typically, Galeazzi fracture-dislocations occur due to a fall on an outstretched hand (FOOSH) with the elbow in flexion leading to axial loading on the hyperpronated forearm Most of these fractures are seen in children, with a peak incidence at age 9-12 years.Īdult Galeazzi fractures account for less than 7 percent of forearm fractures. The ulnar shaft is intact.Ī fracture of distal radius Galeazzi-equivalent fracture is a distal radial fracture with a distal ulnar physeal fracture 2. Galeazzi fracture-dislocations is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint.

Ipsilateral combination of Galeazzi and Monteggia fractures in a ten-year-old patient: a case report. They have not been described in skeletally immature patients, but clinicians should be aware of the risks of proximal migration of the radius that can occur after radial head resection in these patients.Īkalin Y, Akinci O, Kayali C. Essex-Lopresti injuries are seen in patients that have interruption of the interosseous membrane and dissociation of the radius and ulna. Once fracture healing is identified, therapeutic exercises can be initiated and a gradual return to full activities can be expected. The key to treatment of these complex injuries is an anatomic reduction and the creation of a stable joint whether by closed or open methods. Anatomic reduction of the fracture typically leads to DRUJ stability unless soft tissues are interposed in the joint or physis. In children, this can be a true DRUJ dislocation or can also be a fracture-separation of the distal ulnar physis. Galeazzi fractures occur when the current of injury in the forearm fractures the radius shaft and then proceeds through the distal radioulnar joint (DRUJ) to cause dislocation or subluxation of the joint. Injuries to the forearm can lead to fractures of either or both the radius and ulna as well as dissociation between the bones in the forearm.
