Triquetrum Fractures

Fractures of the triquetrum on the dorsal ulna aspect of the wrist are the second most common carpal fracture. Usually they result from a hyperextension injury and represent an avulsion of the dorsal lip of the triquetrum. This is best seen on the lateral x-ray view of the patient. Treatment usually consists of splinting and early mobilization of the wrist as soon as the patient can tolerate this.
