With the rapid development of limb reconstruction surgery, which is powered by classic external fixation and Ilizarov techniques, a large number of related terms and professional jargon have been widely used. To promote the standardized development and academic exchanges of this emerging sub-discipline of orthopedics, this article systematically reviews and analyzes the key technologies and terms that are relatively unified and frequently used in the fields of external fixation and limb reconstruction. The aim is to provide standardized terminology references for relevant scholars and clinicians, and to contribute to the construction of the discipline system.
