The most common wrist fracture is a distal ulnar radius fracture, also known as a Colles fracture or Smith fracture, depending on the direction of displacement of the fracture. For some stable fractures, the fracture is not comminuted and is fixed in a cast or splint after traction repositioning, which is relatively firm and with good patient compliance, it will not be re-displaced. However, for some comminuted fractures with unstable bone masses that affect the articular surface or fractures with collapsed articular surface, the use of plaster or splint fixation after manual repositioning is not firm, and if the patient’s compliance is not good, it is very likely to cause re-displacement. Therefore, for comminuted unstable fractures, it is better to use surgical treatment to cut and reset the fracture, and plate and screw to fix it. After fixation, the fracture is relatively firm, and functional exercise can be started early to avoid stiffness of the wrist and metacarpophalangeal joint later.
