What are the advantages and disadvantages of AO internal fixation technology?
This is the advantage of AO technology. However, AO internal fixation technology emphasizes strong internal fixation, which leads to stress shielding effect at the fracture end and sometimes affects fracture healing. In addition, some people use it improperly, blindly believe in its powerful fixation function, and the movement of the affected limb is not restricted, which leads to delayed healing, nonunion or fracture after healing, and frequent plate breakage. Some people think that AO is not perfect, and many orthopedic surgeons have been researching and developing new internal fixators. If you use AO technology to treat fractures, you must master its essence and follow the principles of AO technology, instead of just learning fur. Fracture needs open reduction and internal fixation in many cases. The purpose of AO method has four points: (1) anatomical reduction of fractures, especially intra-articular fractures. (2) The design of internal fixation meets the requirements of local biomechanics. (3) Non-invasive technique was used to preserve the blood supply of fracture block and soft tissue. (4) Actively and painlessly move the muscles and joints near the fracture in the early stage, so as to prevent the occurrence of fracture diseases. Internal fixation must be superior to the above requirements, which can not only achieve painless rehabilitation, but also significantly shorten the hospitalization date and disability time.
