Orthopedic surgery for steel nailing mainly includes the process of incision, repositioning, internal fixation with steel nails, and suturing. 1. Incision: after anesthesia, disinfection and toweling, incise the skin, subcutaneous tissue and fascia in turn, bluntly separate the tissues, pull apart the muscles and expose the fracture end. 2. Reduction: Trim the raised tissues around the fracture, remove the tissues on the two sides of the fracture end, and complete the reduction with instruments such as reduction pliers. 3. Internal fixation: Place the steel plate on the tension side of the fractured bone, attach it securely and then drill holes with a bone drill, measure the depth and select the appropriate screws, and fix them sequentially. 4. Suture: Thoroughly flush, place drainage according to the situation, reset the pulled apart muscle, cover the plate, and suture the fascia, subcutaneous tissue and skin in turn. All of the above are professional operations and need to be carried out by doctors in regular hospitals.
