Limb Preservation: Total Contact Casting

Diabetics with neuropathic ulcers affect at least one quarter of all diabetics in the United States, and according to Wounds Research, approximately 1 in 5 of these individuals will eventually require an amputation of their foot. Total contact casting has recently become more popular as an option for foot protection, and to mediate the excessive wear and tear that some diabetic foot sores suffer.

What is total contact casting?

As the name suggests, this technique, which is used by many diabetic foot specialists, is a thin cast that is applied to the entire plantar surface area of the foot, as well as the lower leg. Based on its design, the cast can take up as much at 92 percent of the pressure from the ulcer site. Since ulcers often occur on parts of the foot or leg that are repeatedly impacted through daily movement, it is important that they receive as much padding as possible without affecting an individual’s normal walking patterns. Although total contact casting provides relief from certain pressures, the cast works with the natural human gait to make sure that no section of the foot or leg is required to take on excessive weight or pressure.

Does it always work?

Total contact casting has been shown to be effective in the healing of foot and lower leg ulcers, but only those that are noninfected. According to current research, the success rate is between 72 and 100 percent in most patients. A study conducted at the University Hospital Maastricht in the Netherlands examined how total contact casts would fare on infected patients, and of the 28 patients in the study group, only 36 percent showed signs of healing. The study group recommended that individuals with infected diabetic ulcers look toward alternative treatments for healing, according to the American Diabetes Association.

Surgery may become necessary in conjunction with acute infections.
