Tendon rupture suture surgery mainly has several steps of anesthesia, disinfection, debridement, suture and fixation, as follows: 1. Anesthesia: the patient lies flat on the operating table, and local anesthesia, brachial plexus anesthesia, epidural anesthesia and so on are used according to the different parts of the tendon rupture, and the tourniquet stops bleeding. 2. Disinfection, debridement:After the anesthesia takes effect, wound debridement, disinfection, and sheet laying should be carried out, and the wound should be thoroughly debrided to remove the severely contaminated tissues, appropriately enlarging the incision to reveal the proximal and distal ends of the tendon. 3. Suture: There are many ways to suture the tendon, and the common ones are as follows: Kessler suture, Bunnell buried suture, double-cross suture and so on. 4. Fixation:Relax the tourniquet, disinfect the wound again and then bandage it, after bandaging, fix it with plaster locally. If the patient has a tendon rupture, it is recommended to go to the hospital immediately for consultation and examination, and the doctor will provide a suitable treatment plan.
