With the improvement of the living standard of people, the incidence rate of diabetes and peripheral vascular diseases tends to rise year by year. The cases of limb ischemia, pain and necrosis caused by diseases such as diabetic foot, arteriosclerotic obliteration, thromboangiitis obliterans and the like are more and more common, many patients have amputation or risk of amputation, even more patients have wound surfaces which are not healed after amputation, and the disability rate is extremely high. With the popularization of motor vehicles, motor vehicle accidents are frequent, and the risk of ischemic nonunion of fracture patients caused by the high-energy injury is obviously increased compared with the prior art. It has long treatment period, high cost and poor curative effect.
For limb far-end ischemia caused by vascular diseases, treatment modes such as microcirculation improvement, thrombolysis, thrombus removal, vascular stent and the like are mostly adopted in the past, but most of the treatment modes can only temporarily relieve symptoms, the condition of limb ischemia caused by peripheral vascular diseases is not obviously improved, the current curative effect of ischemic nonunion is required to be improved, and the problem can be really solved only by reconstructing limb tissue microcirculation.
In recent years, the proposed technique of lateral bone migration based on the "tension-stress principle" of Ilizarov has become a focus of research and has achieved significant success in the treatment of such diseases. Saves many limbs and functions which need to be cut off in the past.
