Comminuted fracture of the left distal radius is mostly related to indirect violence, such as landing on the back of the hand during a fall, etc. It can be categorized into straight fracture, Barton fracture, flexion fracture, and so on. 1. Extension fracture: it is more common, which may be caused by dorsal extension of the wrist joint and rotation of the forearm when falling, and the palm of the hand landing on the ground, and the violence is concentrated on the cancellous bone of the distal radius. 2. Barton’s fracture: it may be caused by the palm of the hand or the back of the hand landing on the ground during the fall, and the violence is transmitted upward. 3. Flexion fracture: less common, usually caused by the back of the hand landing on the ground during a fall, with the distal end of the fracture displaced to the palmar side and the proximal end of the fracture displaced to the dorsal side. Patients may show symptoms such as swelling, pain, deformity and limitation of activities at the left wrist. Patients with mild symptoms can be reset by manipulation under the guidance of specialized doctors, while patients with severe symptoms can be reset by surgery with internal fixation with Kirschner’s pins, screws or t-plates.
