Reposition is an artificial restoration correct position shifted splinters of bone fractures.
When fresh fractures main obstacle to reposition is a contraction of the muscles, in the later stages - cicatrical changes of the surrounding soft tissues. In some cases reposition difficult infringement between fragments bones, muscles, tendons, nerves, fascias and other nearby tissue.
Reposition can be made simultaneously or within a certain period of time (the so-called dynamic reposition). Simultaneously reposition can be manual or hardware; closed (through the surrounding soft tissue) or open (with the operational exposure ends of fragments). Dynamic reposition using stretching (see)when there is a gradual relaxation of muscles.
The position of fragments when reposition necessarily controlled by radiography or fluoroscopy.
Successful simultaneously reposition of fragments is possible only with good anesthesia. Depending on the type, location and other features of fracture during reposition apply anesthesia or local anesthesia. Anaesthesia to reposition should provide relaxation of the muscles in the damaged area, relieve pain. Good effect gives provodnikova anaesthesia or introduction to the hematoma between fragments 10-25 ml of 2% solution novokaina. When reposition in persons with muscular have to use anesthesia, often ward. In children reposition produce mainly under General anesthesia. Cm. also Fractures.
