Triquetral fracture | Figure 1

Triquetral fracture

Lateral radiograph of the wrist shows an avulsion fracture (arrow) of the dorsal triquetrum. The triquetrum is the second most commonly fractured carpal bone behind the scaphoid. Fractures occur after a fall on an outstretched hand and occur in three locations: along the dorsal cortical surface, at the triquetral body, and along the volar surface. Dorsal fractures are most common.

AP radiograph of the wrist shows a longitudinally oriented fracture of the trapezium (arrow). Trapezium fractures are uncommon. When they occur, they are often associated with other fractures at the first metacarpal base or injuries of the wrist. Trapezium fractures occur as a result of direct axial loading of an abducted thumb.](https://app.figure1.com/case-detail/01362978-33aa-4d40-9981-06c35fb7c52c)

AP (image 1) and a lateral (image 2) radiograph of the wrist show a displaced Salter-Harris type II fracture of the distal radius. The fracture is translated dorsally by more than 100% with overlap of the fracture fragment from the donor site. A Salter-Harris type II fracture of the wrist is one of the most common fractures identified in children. It occurs from a fall onto an outstretched hand.](https://app.figure1.com/case-detail/0b287a42-b230-40d0-bb69-eaa0b27eebf2)
