Extremity fractures should be the most common fractures in orthopedics. In trauma orthopedics, the dominant type of treatment is mainly extremity fracture, which includes upper extremity fracture, lower extremity fracture, periarticular fracture, and foot and ankle fracture. This is a common fracture, in general, the treatment method in the past is incision and reduction, plate fixation, which is the surgery, the more serious treatment method. But now with the development of orthopedics, basically the incision and plate fixation is less and less, and the minimally invasive treatment method is generally used. Minimally invasive treatments mainly include intramedullary nail fixation, or percutaneous plate fixation, percutaneous pin fixation, or screw fixation, including pelvic and acetabular fracture surgeries, which can also be treated minimally now by using screw and rod system for fixation. Usually no large incisions are made, all small incisions are made. Of course, conservative treatment can also be used for those without significant displacement or with little displacement. Conservative treatment includes manipulation, Chinese medicine application, including traction is also feasible.
