Background
The clavicle is S-shaped and is arranged between the sternum stem and the acromion. Is the only bony framework connecting the lower and upper limbs and the trunk. The clavicle is positioned under the skin and superficial, and is easy to fracture under the action of external force, the incidence rate of the clavicle fracture accounts for 2.6-5 percent of the total fracture, wherein the middle-segment fracture of the clavicle accounts for about 2/3 percent of the total fracture of the clavicle, and the clavicle fracture is mostly generated in children and young adults. Internal fixation therapy is one mode of clavicle fracture treatment, and among them, a nail plate system is one of the most commonly used internal fixation modes. The internal fixation treatment mode principle is to cut at the fracture broken end, place the bone fracture plate, make the bone fracture plate cross the fracture position, fix the bone fracture plate at the far and near both ends of the fracture with screws and make the skeleton at the fracture end obtain effective fixation.
