Background
Bone fracture is one of the most common diseases in orthopedics clinic, and accounts for about 16% of all musculoskeletal system injuries. Fracture reduction and fixation are the key to fracture treatment. Manual reduction is an effective method for reducing fracture by reducing the fractured bone end by a doctor in a free-hand way. The good manual reduction and external fixation have the advantages of small wound, less pain and the like, and can effectively promote fracture healing. Improper manual reduction and fixation can cause injury to fractured bones, soft tissues, blood vessels and nerves, resulting in complications such as re-displacement of fractured bones and seriously affecting fracture healing. Therefore, the method has great significance for enabling young doctors to have good manual reduction and fixation technology through scientific and effective training.
Traditionally, under the guidance of teachers, young doctors directly perform manual reduction and fixation exercise on fracture patients, and besides the defects of long learning period, poor repeatability and the like, the risk of reduction failure also exists. On the other hand, in order to alleviate the pain of the fracture patient and improve the curative effect, in recent years, the chances of the young physicians to learn the fracture reduction through clinical operation are gradually reduced, and the cultivation of the young physicians is not facilitated. Therefore, if a real and reliable fracture reduction device is used for clinical teaching, training and evaluation, the reduction technology of young doctors is greatly improved.
