The best time to rehab a finger injury is within three months of the injury. Finger injury recovery depends on a number of factors such as the presence or absence of fractures, tendon damage, and the extent of skin damage. 1. No fracture, just soft tissue and ligament damage, can be recovered within three weeks. Within three weeks, you can avoid excessive training and do light activities, which will help to reduce swelling and adhesions at an early stage. 2. If there is a fracture and the tendon has healed to a certain extent after three weeks, the brace can be removed and functional exercises can be gradually strengthened without causing tissue fracture or injury. At the same time, local physical therapy or heating can be done to promote local circulation and dissipate inflammation. Maximum recovery can be achieved through gradual and continuous adjustment of comprehensive treatment within three months. 3. Combined skin and soft tissue necrosis, due to infection or trauma caused by skin and soft tissue necrosis, need to wait until the trauma is stabilized and then repair, some need skin graft, flap repair, or even amputation. At this time, the finger needs to wait until the wound is completely healed, in order to have a more normal function and shape recovery. The effect of natural recovery after finger injury is not satisfactory, so we need to take the initiative to exercise through the doctor’s professional guidance in order to achieve a good recovery effect.
