The process of internal fixation of fracture plate is mainly anesthesia, preparation of the operation area, surgical incision, reduction of fracture breaks, observation of reduction, fixation of the plate, and rinsing and suturing. 1. Anesthesia: according to the fracture site and fracture condition, general anesthesia will be performed in most cases. In some cases, regional block anesthesia will be performed. 2. Preparation of the operation area: including preoperative sterilization and laying of sterile towel. 3. Surgical incision: In the pre-localized and marked surgical area, surgical incision is made layer by layer, such as incising the skin, subcutaneous tissues, deep fascia, and pulling open the muscles in order to fully expose the fracture end. 4. Repositioning the fracture break: after treating the blood clot of the fracture break, carry out the repositioning of the fracture break and temporarily fix it with Kirschner’s pin or repositioning forceps. 5. Observation of the reduction: C-arm fluoroscopy is used to observe the reduction, and the operation is continued after the reduction is correct. 6. Fixation of steel plate: choose the appropriate length of steel plate, drill holes and screws to fix the plate. 7. Flush suture: Close the surgical incision layer by layer after flushing the wound.
