7/7/2023 0 Comments Galeazzi fractureĪfter the injury, the fracture is subject to deforming forces including those of the brachioradialis, pronator quadratus, and thumb extensors, as well as the weight of the hand. If the fall is on the outstretched hand with forearm in pronation, the dislocation is dorsal, and if forearm is in supination at the time of injury, the dislocation is volar. The dislocation of ulnar head in Galeazzi fracture dislocation may be dorsal (commoner) or volar (rare) depending on the mechanism of injury. Galeazzi fractures are sometimes associated with wrist drop due to injury to radial nerve, extensor tendons or muscles. Injury to the AIN can cause paralysis of the flexor pollicis longus and flexor digitorum profundus muscles to the index finger, resulting in loss of the pinch mechanism between the thumb and index finger. A purely motor nerve, the AIN is a division of the median nerve. Anterior interosseous nerve (AIN) palsy may also be present, but it is easily missed because there is no sensory component to this finding. Forearm trauma may be associated with compartment syndrome. This injury is confirmed on radiographic evaluation. Pain and soft-tissue swelling are present at the distal-third radial fracture site and at the wrist joint. It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint the injury disrupts the forearm axis joint. The Galeazzi fracture 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.
