Whether the thumb tendon rupture surgery can be restored to the same as before depends on the degree of tendon rupture and the patient’s postoperative recovery, etc. Some patients can be restored to the same as before. After thumb tendon rupture surgery, you need to correctly and actively carry out functional exercises for the fingers to avoid adhesion of the hand tissues, which can help the fingers to return to their previous state. However, for thumb tendon rupture with severe infection and necrosis before surgery, more tendon tissues will be removed during the surgery, and contracture deformity and tissue adhesion may occur after the surgery, which will affect the finger dexterity, and most of them are difficult to be restored to the previous state. In addition, wound infection and inadequate functional exercises may affect wound healing and cause adhesions in the surrounding tissues, thus affecting the recovery of finger joint function after thumb tendon rupture surgery. After thumb tendon rupture surgery, rehabilitation training should be carried out under the guidance of the doctor, and timely consultation should be made when hand pain occurs.
