The recovery time for finger fracture stiffness varies from person to person, with the optimal recovery time being around the 4th-6th week after surgery. In clinical practice, patients with finger fractures are usually braked and helped to reset the bones by external fixation in plaster as well as surgical fixation. At 4-6 weeks postoperatively, the fracture heals initially, the local swelling gradually decreases, and the hematoma at the fracture end is gradually absorbed. However, due to long-term inactivity, the finger may have different degrees of joint adhesions and stiffness. It is recommended to conduct rehabilitation training under the guidance of a professional rehabilitation doctor at this time, which is the best time to recover from finger stiffness. Rehabilitation training mainly includes physical therapy such as infrared light and hot compresses to promote blood circulation and improve the range of motion of the joint, as well as smooth and gentle passive stretching of the fractured joint, joint loosening movements and active movements of the involved joint. The main purpose of rehabilitation training after fracture surgery is to eliminate residual swelling, soften and stretch the fibrous tissue, increase the range of motion of the joint, enhance muscle strength and train muscle dexterity, and help promote recovery.
