Whether a patient’s finger tendon can heal on its own after an injury should be determined by the extent of the tendon injury and should not be generalized. Finger tendon rupture is usually seen in trauma, but it may also be due to chronic injury, which needs to be combined with physical examination to determine the condition of tendon rupture. If the tendon is partially ruptured, the tendon can heal on its own with the proper treatment by the doctor, such as local fixation and other symptomatic treatment. However, if the tendon is completely ruptured, it is usually necessary to surgically suture the ruptured tendon and immobilize it in a cast for 4-6 weeks. After the cast is removed, the patient can gradually carry out functional training of the finger, avoiding the use of violence, in a gradual manner, to avoid causing the tendon to rupture again, while aiding in the rehabilitation with blood activating and stasis removing drugs, such as Pan Long Qi tablets. Because adhesions may occur after the tendon rupture heals and affect the flexibility of finger movements, patients should try to strengthen functional exercises, such as active or passive flexion and extension activities, to restore finger functions.
