As the finger is immobilized for a long time, it is easy to lead to stiffness of the finger joint or adhesion of the surrounding soft tissues, and the recovery takes about 1~3 months, which is related to the severity of the injury, the degree of adhesion, and the situation of functional exercise. 1. For patients who have been immobilized in plaster for a relatively short period of time and have no or mild adhesions in the joints, they can return to normal in about 1 month after removing the plaster and through active functional exercises. 2. For patients who have been immobilized in plaster for a long time, with serious adhesion of tendons and other soft tissues around the joints, and who do not actively carry out scientific functional exercises after the removal of the plaster, the recovery time is often longer, and it will take about 3 months or even longer. 3. For those with serious injury, especially those with deformity of the finger joints, the recovery time is often longer, or even cannot be completely recovered. It is recommended that patients go to the hospital for consultation and functional recovery under the guidance of professional physicians.
