The Ilizarov method: Rancho technique.

Ilizarov's methods of creating new bone within a widening distraction gap have been modified at a number of centers around the world. The Rancho technique substitutes divergent titanium half pins for Ilizarov's tension wires (in most locations), while retaining the rings, hinges, posts, and functional assemblies of the Ilizarov apparatus. In this way, the versatility of the Ilizarov system has been maintained, yet with less muscle impalement and greater functional capacity of the limb. The unique biocompatibility of titanium lessens implant site sepsis.
