The Tong’s tendon suture is a tendon suture that has been developed over a large amount of clinical work. The main method is to leave about 1 cm at both ends of the tendon and to make a loop with tendon sutures, so that the tendon bundle and tendon membrane are sewn into the loop to increase the stability of both ends of the tendon. It can be applied to the tendon repair of the hand and also to the Achilles tendon. In short, it provides good stability and prevents the tendon from being reeviscerated or ruptured during the suturing process.
