Adhesion of the tendon of the severed finger needs to be handled according to the patient’s condition and can be treated conservatively or surgically. If the adhesion of the tendon of the severed finger is mild, it can be treated conservatively by small passive movements of the finger, such as flexion and extension of the finger, to promote functional recovery and restore the normal range of motion of the tendon, but it should be gradual. If the adhesion of the tendon of the severed finger is more serious, then conservative treatment is not so ideal, and surgery is needed to loosen the adhesion of the tendon, after which rehabilitation training should be continued. It is important to rest regularly, eat a balanced diet, and avoid smoking and alcohol. Tendon training for severed fingers is a relatively long process, and it is necessary to insist on training and train correctly under the guidance of the doctor.
