Yes, because diabetic foot ulcers are actually very complex conditions with a wide variety of causes, each doctor has a different focus of treatment, which leads to different main ways of treatment in different departments. Here I will briefly introduce the treatment methods of several common departments: burn plastic surgery – skin grafting The most common method of burn plastic surgery is skin grafting, which is used to actively control blood sugar, blood pressure, blood lipids, etc., and control the development of infection in the early stage, and eventually repair the wound through flap transfer and skin grafting after treatment such as debridement and negative pressure drainage in the later stage. However, diabetic patients have poor resistance and immunity, wound healing is slow, and skin extraction site is prone to infection; normal healing tissue must grow on the wound surface before transplantation can be considered, at this time, healthy skin can grow through natural growth, and there is no need for skin grafting. Moreover, skin implants are prone to secondary infection and necrosis, and the cost of treatment is high, and the cost of a skin implant is often tens of thousands of dollars, which is a great burden for ordinary families. Orthopedics: Amputation and bone removal surgery Amputation is one of the most common methods for treating diabetic foot, especially for patients with lower limb vascular occlusions, patients with heavy and difficult to control infections and ulcers, and patients with unbearable pain, etc. Amputation is often requested. Amputation is a quick way to control infections, but there is often a serious problem of over-amputation. Moreover, the wound recurrence rate of patients after amputation is extremely high and the mortality rate remains high, with a reported mortality rate of 20% within 6 months and up to 70% within 5 years after major amputation in diabetic foot patients. Therefore, amputation treatment is not the best treatment for diabetic foot. Bone relocation surgery. It is a new technique for the treatment of diabetic foot, and its treatment concept and method and effect are increasingly understood and validated by clinical orthopedic surgeons. The treatment principle of this method is that a certain tension is generated when biological tissues are slowly pulled, which can stimulate tissue regeneration and active growth. The human skeleton, like the epithelial and connective tissues of the human body, has great regenerative potential and plasticity. By giving the skeleton a suitable stressful pull, the skeleton and its attached muscles, fascia, blood vessels and nerves will grow simultaneously. The rehealed site generates a large capillary network in order to rapidly produce new bone scabs, which in turn improves blood flow to the lower extremity. However, the surgery is associated with many complications, such as non-healing bone ends, soft tissue infection, pain, shortened deformity of the affected limb, foot drop deformity, and pin tract infection; many patients are less tolerant and have reduced compliance at a later stage, which affects the outcome of the surgery. Vascular surgery: interventional treatment Interventional treatment of diabetic foot is an emerging diabetic foot treatment method widely adopted internationally. Through local puncture techniques, special catheter guidewires and balloons are used to dilate the blood vessels of the diseased segment with or without stent placement, so as to reopen the narrowed or occluded segment of blood vessels, thereby improving the blood supply to the lower limbs and promoting the healing of ulcers. Currently, there are two main means of placing balloons and stents, which need to be used according to the different conditions of the patient. Generally speaking, for patients with segmental stenosis of the lower extremity vessels, balloons are used, which can dilate the vessels; for those with severe stenosis, stents can be placed to keep the vessels open. However, surgery has certain risks, prone to recurrence and higher treatment costs; it can easily lead to the dislodgement of fine plaques and induce cardiovascular and cerebrovascular diseases. Neurosurgery: lumbar sympathetic nerve block and nerve release Diabetic foot neuralgia is a kind of neuropathy with insidious onset and the pain gradually worsens with time. Lumbar sympathetic nerve disruption is an effective treatment for diabetic foot neuralgia, with the advantages of precise destruction and easy acceptance by patients. Nerve release is a procedure for neuropathy. For patients with numbness, pain, and foot drop in the lower extremities, dorsal foot, plantar and toes, the common peroneal nerve, deep peroneal nerve, and tibial nerve are often released to reduce the pressure on the local nerves and thus relieve pain. These two methods are mainly for the treatment of diabetic neuralgia, and whether they are effective for wound healing or not is yet to be further scientifically proven. Moreover, the surgery has many potential complication risks, such as the risk of accidental injection of ethanol into the spinal canal, abdominal cavity or blood vessels by neurodesis, injury to the kidney, renal pelvis, urethra or intervertebral disc caused by puncture needle or nerve release drugs, injury to the blood vessels of the posterior abdominal wall, back pain, sympathetic neuralgia, genitofemoral neuralgia, hypotension, and failure of ejaculation. Endocrinology: internal medicine treatment Endocrinology treatment of diabetic foot, commonly mainly oral drugs and intravenous drip, from control of blood glucose, blood pressure, blood lipids, etc., to improve lower limb circulation, restore the patient’s nerve function, control infection and other treatment, over-reliance on drugs, thus ignoring the treatment of local infection such as debridement, treatment is one-sided. Diabetic foot is a very complex condition, and medical treatment is one of them, but it also needs to do debridement of local wounds for different patients to reduce the germ load and create conditions for wound healing. Orthopedic surgery: diabetic foot load reduction and orthopedic shoes The most important manifestation of diabetic foot is ulceration, and one of the external causes of ulceration is stress damage to the tissues due to excessive local stress, prolonged stress and excessive friction on the sole of the foot. Excessive pressure on the bottom of the foot is the culprit of diabetic foot. In diabetic patients, lesions occur in the nerves and peripheral blood vessels of the foot, resulting in a significant decrease in plantar perception and eventually the formation of ulcers and infections. Specially designed therapeutic shoes with pressure-reducing insoles change the pressure in the patient’s foot, thereby reducing the risk of ulcers. Practice has shown that patient compliance has a great impact on the outcome; the effect of pressure reduction is lower than that of plaster supports and other methods, and should not be used as the main method of pressure reduction; for patients who have developed diabetic foot ulcers, wearing orthopedic shoes is no longer the best choice, and timely and effective comprehensive treatment such as debridement is the key.
