The healing of foot symptoms does not mean that the foot is no longer protected by a special foot device, but rather that a suitable foot device is needed to prevent the reappearance of symptoms. Although the injury has healed, the foot condition that caused it still exists, and if left unattended once healed, the pain of the disease may soon return. A functional foot device that conforms to the condition of the foot and disperses the plantar pressure well can be a good preventive measure for the affected limb. For patients who have healed from minor amputations, partially padded foot devices, with some processing of soles and insoles, are also needed to address the residual function of the affected foot. Foot device can be “printed” Nowadays, there are few choices of special shoes for diabetic foot on the market, and the foot device is too specialized, so it is difficult to understand it. In the face of their feet, many “sugar lovers” are willing to do nothing: although they want to do something to protect their feet properly, but suffer from the lack of knowledge, do not know where to start. The Department of Endocrinology of the 454th PLA Hospital is the Diabetic Foot Center of Nanjing Military Region, which has a medical team with endocrinologists as the core and orthopedic, vascular and imaging doctors as members, and has developed a variety of unique and effective new technologies for foot disease treatment, such as the “Plantar Pressure Correction System” that can automatically produce orthopedic insoles to prevent the occurrence of diabetic foot disease. “Dr. Sun Xinjuan from the Endocrinology Department of 454 Hospital gave a lot of practical advice on how to choose foot devices for patients, including some high-tech products, which is refreshing. ”Print” a pair of insoles Dr. Sun said that patients should choose some small devices or small supports to avoid foot ulcers in advance when the foot has not yet been traumatized, but deformities have occurred. For example, when a bunion occurs, you can choose special socks similar to five-finger socks to separate the toes to avoid ulcers from occurring when the skin between the toes is too close; if a second toe is riding on the big toe, you need to use some elastic small devices to borrow external force to put the toes back to their normal position, also to avoid pressure ulcers from occurring between the toes for a long time. Speaking of which, Dr. Sun pointed out that most foot deformities are caused by long-term poor gait. Anyone with diabetes who has foot abnormalities should choose appropriate insoles to equalize plantar pressure and correct gait to slow the progression of foot disease. There is a new way for patients to quickly get the right insoles, which is to use the emerging 3D printer to “print” a pair of insoles that fit their feet perfectly and are their own. 3D printers, which you may have heard of, print layers of bonded material to form a usable three-dimensional object, rather than just flat graphics like traditional printers. However, a pair of suitable insoles is not just a casual hit. Before making them, doctors need to test the pressure distribution on the patient’s soles, determine the size of the pressure on the soles according to different colors, find out the area most in need of pressure reduction, and then design individualized insoles according to the patient’s own problems, and finally make them. This allows for individualized treatment for the patient’s own unique problems. The patient uses the device that best fits his or her foot type, and the best combination of decompression and orthopedics, prevention and treatment is achieved. For patients who have undergone amputation, it is also necessary to have the inside of the shoe filled. Because the shape of the foot after amputation changes significantly compared to a healthy foot, some parts of the foot that would not otherwise come into contact with the inside of the shoe begin to come into contact with the shoe, and if the inside of the shoe is not padded, it is easy for these parts to wear down and ulcers to occur. Practical choice of footwear Professor Xu and Dr. Sun coincidentally offered some good advice to diabetic foot patients on the purchase of shoes: ① When there is no obvious foot abnormality, for the purpose of prevention, you can choose “sugar man shoes” with a higher and wider front, breathable fabric, seamless lining and a more flexible sole; ② “Darco (Darco shoes)” and “Dr. Comfort (Mr. Comfort)” are professional shoes for diabetic foot, and “sugar people” with foot deformities or injuries can choose to buy them online. ③ Common sports brands in shopping malls, such as “New Balance (New Balance)” some styles of shoes are wider and deeper, more suitable for diabetic foot patients into special insoles, patients can refer to the shape and structure of professional footwear for diabetic foot, according to their own situation in the market to buy; ④ When choosing shoes, pay attention to the inner surface of the shoes, there should not be inward rough projections such as stitching joints to avoid abrasion of the foot skin and serious consequences such as ulcers.
