The most common hand fractures are distal radius fractures and metacarpal and phalangeal fractures or dislocations. Hand fractures that are not significantly displaced can be fixed in a cast to restore the anatomic position of the fracture and to brake the fracture to help it heal in a normal position. When the fracture is repositioned, a cast can be applied at the same time, and the patient’s pain will be significantly reduced because the fracture end will be less displaced and misaligned. The pain will be significantly reduced after conservative treatment of the hand fracture, repositioning and plaster fixation, but the swelling caused by bleeding has not completely subsided within 3-5 days after treatment, so the pain in the wrist joint or fracture site will still exist after conservative treatment, but it will be relatively reduced, and the pain will gradually disappear after the swelling subsides over time.
