There are three common surgical methods for tibia fracture surgery: extramedullary fixation, intramedullary fixation, and external fixation frame fixation. Tibia fracture surgery extramedullary fixation usually refers to incision reduction plate screw internal fixation. A longitudinal incision is made in the fracture to reveal the fracture, and the fracture is then repositioned and fixed with screws at both ends of the fracture, so that the fracture reaches a stable state, and the wound is closed with irrigation suture, and the field is bandaged, and the operation is finished. There is also closed intramedullary nail fixation, where an incision is made below the knee joint, the medulla is expanded and a suitable intramedullary nail is inserted through the end of the fracture and locked in place with screws. There is also a kind of external fixation frame fixation, after the fracture is manipulated or cut and repositioned, holes are made in the calf skin to locate and implant an external fixation frame to fix the two ends of the fracture. These are the procedures for the three common surgical approaches to tibia fracture surgery.
