Pathogenesis and Management of Diabetic Foot Ulcer
Diabetic foot ulcers are very significant problems of diabetes that often precede with amputating the lower part of the body. Very common underlying etiologies are trauma, neuropathy, high plantar pressures, deformity, and peripheral arterial disease.
Foot Ulceration Etiology
The etiology of a diabetic foot ulcer normally has a lot of components. One recent multi-centre study showed that sixty-three percent of diabetic foot ulcer attributed to the critical triads of peripheral sensory neuropathy, deformity, and trauma. Additional factors in foot ulceration include callus formation, ischemia, and edema. In diabetic foot ulcers, infections are rarely implicated, although these ulcers are most susceptible to complications once the presence of wound is starting to get in. Most of the risk factors for diabetic foot ulcer are mostly predisposing factors for amputations, since ulcers are the main cases of amputation.
Some Risk Factors Involving Diabetic Foot Ulcer
All ulcers are generally contaminated which explains why culture of non-infected wounds are generally not recommended. A polymicrobial infection mostly predominates in diabetic foot infections. This includes varieties of aerobic gram-positive cocci, anaerobes, and gram-negative rods.
For patients with a longstanding diabetic foot ulcer, radiographs must be obtained to rule out possible osteomyelities. However, these are not very sensitive indicators though of acute bone infections. If clinical suspicions generally indicate osteomyelitis and radiographs are negative, undergoing a leukocyte or bone scanning is mostly falsely positive because of Charcot's arthropathy or hyperemia. Bone biopsy is also necessary to establish the firm osteromyelities diagnosis.
Prevention of Diabetic Foot Ulcer
To avoid amputation, it is important to prevent initial foot lesions. One of the best approaches is to use a team of multidisciplinary professionals, committed to limp possible salvage. Additionally, centres that have their own instituted teams just for this purpose have reported dramatic reductions in lower-extremity amputations, while improving the rate of a primary-ulcer healing.
Most commonly, patient education plays a major role in the prevention of a diabetic foot ulcer. This would include proper foot hygiene instructions, proper footwear, daily inspection, and the immediate treatment upon finding new lesions.
Regular foot-care examinations also play a lot in preventing diabetic foot ulcers. Using therapeutic shoes that have pressure-relieving insoles are also important element of preventing foot ulcers. This has long been associated with noteworthy reductions in the development of foot ulcers.
To correct structural deformities that can no longer be accommodated just by using therapeutic footwear, elective surgery is the answer. Common procedures of this type of surgery normally include metatarsal osteotomies, hammertoe repairs, Achilles tendon lengthening, and plantar exostectomies. For patients with neuropathy, these surgeries can be done under local anaesthesia.
It is important to know some facts about diabetic foot ulcer. This is helpful enough to at least prevent your foot from getting amputated just because of lack of knowledge of this foot problem. Take time to learn more about this.
