![]() ![]() The mechanism of injury is commonly a FOOSH (Fall on an Outstretched Hand) and often dictates the fracture pattern. According to the literature, 79% of the carpal fractures are seen in the scaphoid, 14% in the triquetrum, 2% in the trapezium, 2% in the hamatum, 1% in the lunatum, 1% in the pisiform, 1% in the capitatum, and 0.2% in the trapezoid. ![]() Unrecognized carpal bone fractures may lead to complications such as nonunion, osteonecrosis, and degenerative osteoarthritis resulting in persistent pain and functional impairment. In acute traumatic settings, the difficulty in recognizing fractures of the wrist on the initial radiographs can lead to missed wrist fractures. Wrist trauma may engender serious osseous and soft-tissue injuries. Therefore, in acute and subacute setting, computed tomography may be helpful for the detection of subtle fractures, and magnetic resonance imaging, for the early diagnosis of occult fractures and ligament injuries. Patients without osseous injuries may present intrinsic and extrinsic ligament tears that may lead to carpal instability when they are clinically and/or radiologically missed. The initial radiographs may miss the fractures and result when untreated in complications as nonunion, osteonecrosis, and degenerative osteoarthritis.įractures of the distal radius and of the scaphoid may be associated with ligament injuries, most frequently the scapholunate complex, which are often overlooked at the emergency department. Acute and subacute wrist trauma predominantly consist of fractures of the distal radius in elderly patients and most frequently carpal fractures (scaphoid, followed by triquetrum and hamatum) and avulsion fractures of the ulnar styloid in younger patients, especially in sports-related injuries but also in work activities. ![]()
