The Ilizarov system consists of individual parts that can be assembled into an unlimited number of configurations. The adjustability of the apparatus allows control of bone angulation, rotation, translation, and lengthening or compression at one or more levels of a bone, either simultaneously or consecutively. Fixation elements are the components that secure wires to the frame: the wire fixation bolts. Pin-gripping clamps also fit into this category. Supporting elements (where wires attach) include various diameters of half-rings, full-rings, specialized rings ( ⅝ circle, Omega-shaped) and arches, as well as plates—both straight and twisted—and posts of different lengths. Connecting elements comprise the threaded rods and telescopic (or ratchet) tubes that connect the supporting elements together. Assembly elements include the nuts, bolts, and sockets that fasten things together. Sliding elements (buckles, bushings), as the name implies, permit supports and other elements to move with respect to each other.
