Background

Distal radius fractures are one of the most common fractures in emergency department, and are frequently seen in middle-aged and elderly women. The injury mechanism is often a fall, in which the hand is stretched to prop up the ground, resulting in a fracture caused by the concentration of violence on the distal cancellous bone of the radius. Epidemiological studies show that the incidence of distal radius fractures is increasing with aging population and changes in lifestyle. Also, severe weather and environment can increase the risk of accidents.

For most of fractures of the distal radius, especially common straight fractures (Colles fractures), the fracture can be treated by combining traditional Chinese medicine bone setting techniques with plaster fixation.
