Background
The distal radius fracture is very common in usual fracture treatment, the common saying of the distal radius fracture is wrist fracture, and the fracture position is within 2-3 cm of the distal radius. The far end of the radius is the junction of the bone end and the diaphysis, and is also the junction of the cancellous bone and the cortical bone, which is a weak part on stress and is easy to fracture. If a person falls down and lands on the palm, the wrist joint stretches to the back, and the fracture of the far end of the radius with the fractured end shifted to the back is called Colles fracture, and most Colles fractures are clinically encountered. When a person falls, the back of the hand touches the ground, the wrist joint bends to the palm side, and the fracture of the far end of the radius with the fractured end moving to the palm side is called Smith fracture. A fracture of the distal edge of the radius, called Barton fracture, following a volar or dorsal displacement of the hand and carpus, is a special fracture of the distal radius. Generally, pain, swelling, deformity and dysfunction of the wrist joint occur after fracture. Most distal radius fractures can basically achieve good prognosis through conservative treatment, manual reduction and splint or plaster external fixation.
During the injury process, under the pulling action of external force and muscles, the patient can have fracture shortening and angulation displacement after being injured, so that the wrist needs to be pulled in the recovery process, meanwhile, for better reduction, two medical staff are usually needed to carry out counter traction, one person pulls the elbow and the other person pulls the palm.
