The dangers of undisplaced anterior radial displacement may include hand deformity, joint stiffness, traumatic arthritis, and hand dysfunction. 1. Hand deformity: Undisplaced anterior radius may heal abnormally, resulting in wrist deformity. 2. Joint stiffness and traumatic arthritis: the anterior end of the radius is close to the wrist joint, and displacement without resetting may cause stiffness of the wrist joint, which may also cause traumatic arthritis. 3. Hand dysfunction: hand deformity, joint stiffness, traumatic arthritis may cause hand movement limitation and other dysfunctions. Displacement of the anterior end of the radius should go to a regular hospital in time, and the doctor should give the correct treatment according to the specific condition to avoid the above risks.
