Background

Chronic refractory wounds refer to wounds that have no tendency to heal for at least 1 month of treatment. According to global estimates, the prevalence of chronic wounds is about 1-2%, and is high in developing countries and in people over 65 years of age. At present, about 3000 million people develop chronic refractory wounds on the body surface in the skin, operation incision, sinus tract and other wounds of about 1 hundred million people in China. The etiology of the chronic wound is mainly metabolic diseases (diabetes), wounds, infection, burns, tumors and lower limb vascular diseases, wherein the proportion of the metabolic diseases to the diabetes is increased year by year, and the etiology of the chronic wound is up to 33.3% through domestic investigation by 2008, and the chronic wound becomes the main etiology of the chronic intractable wound. In the life of diabetes patients, about 25 percent of patients (with morbidity) have diabetic feet with different degrees, wherein the diabetic feet refer to the pathological changes of peripheral arteriole occlusion caused by diabetic neuropathy including unextended nerve sensory disturbance and vegetative nerve damage, lower limb angiopathy-arteriosclerosis, or foot pain, foot ulcer, foot gangrene and the like caused by skin microangiopathy and bacterial infection. Diabetic feet appear in diabetic patients, which indicates that the damage of nerves and blood vessels of the body, especially microvessels, reaches a serious stage, the worst result is amputation, the final treatment aim is to protect limbs, and how to promote the wound healing of the diabetic feet and avoid amputation are always the clinical problems of diabetic foot treatment.

The origin of the theory of the transverse tibial bone migration and the current popular treatment method aim at the migration of bone fragments, and Novekov professor in the Ilizarov medical center thinks that the transverse bone migration promotes the regeneration of blood vessels to artificially cause fractures and promote the body reaction to generate the effect which is controlled by the hand of an orthopedic doctor and is the operation basis of the transverse tibial bone migration. The reasons for bone migration include decreased intra-osseous pressure, relief of vasospasm in the bone marrow, etc.; see in detail: the origin and development of the Ilizarov transverse tibial bone migration technology in the Beijing bone lengthening bone migration treatment center, Jichong's doctor Qulong paper, can see that the traditional theoretical record emphasizes the fracture of the tibia, namely, the tibial bone fragments are to be migrated, so as to play the roles of increasing the vascular network and reducing the intra-osseous pressure, which brings the cognitively opposite teaching to the inventor's invention. Therefore, the inventor's invention is a significant technical innovation that overcomes the prior technical bias.

In the traditional operation process, large-area skin on the tibia is firstly cut to expose the tibia, then holes are drilled on the tibia along a rectangular bone block by using an electric drill, two holes are drilled on the rectangular bone block by using bone needles to fix the bone block by using bone needles, then supports are fixed on two sides of the bone block by using the bone needles, and finally the bone block is lifted. The whole operation process is long in time consumption, the process is complicated, the damage to the tibia is large, the operation risk is large, the patients with multiple wounds are infected more easily, the requirement on the bone quality of the patients is high, and the operation cannot be completed by the patients with poor bone quality.
