Total contact casting (TCC) — the application of a well-molded, minimally padded plaster or fiberglass cast to distribute weight-bearing forces across the entire plantar surface of a diabetic foot — is the gold-standard treatment for neuropathic plantar foot ulcers in patients with adequate circulation. Despite its proven efficacy (healing rates of 72–100% in randomized controlled trials), TCC remains underutilized in clinical practice because of the technique’s learning curve and the availability of less effective but more convenient alternatives.
Mechanism and Evidence
How TCC heals neuropathic ulcers: plantar neuropathic ulcers result from repetitive pressure and shear at a bony prominence in an insensate foot — the patient cannot sense the tissue damage occurring with each step. TCC heals ulcers not by local wound management alone but by dramatically reducing plantar pressure at the ulcer site (up to 84% pressure reduction) and enforcing offloading compliance — the cast cannot be removed by the patient. Evidence base: TCC vs. removable cast walkers — TCC achieves 90% healing vs. 65% for removable devices in randomized trials; the key difference is compliance — patients remove removable walkers 72% of walking hours. TCC vs. half-shoes and heel wedges: TCC superior for forefoot and midfoot ulcers. Contraindications: infected wounds (active cellulitis or osteomyelitis — TCC traps infection and accelerates destruction); critically ischemic limb (ABI <0.5); fragile skin from severe peripheral edema; patient unable to ambulate at baseline. Application technique: wound debridement and dressing; foam padding over bony prominences and malleoli; well-molded plaster inner layer followed by fiberglass outer layer in plantigrade position; cast changed weekly (more often if drainage is excessive); healing assessed at each change. Removable cast walker (instant TCC): a removable walker rendered irremovable by wrapping with a cohesive bandage — nearly equivalent to TCC in compliant patients and easier to apply.
After Healing
Prevention of recurrence: custom accommodative orthotics with extra-depth diabetic shoes within 4 weeks of healing — the healed ulcer site remains a vulnerability; annual podiatric surveillance for recurrence.

Frequently Asked Questions
How often should diabetics have their feet checked by a podiatrist?
People with diabetes should have a comprehensive foot examination by a podiatrist at least once per year, and more frequently (every 1–3 months) if they have neuropathy, poor circulation, history of foot ulcers, or active foot problems.
What is the biggest foot danger for diabetics?
Loss of protective sensation (neuropathy) combined with poor circulation creates a dangerous combination — minor injuries can go unnoticed and become infected. Foot ulcers affect 15–25% of diabetics over their lifetime and are the leading cause of non-traumatic amputations.
Does Medicare cover diabetic foot care?
Yes. Medicare covers annual diabetic foot exams for patients with peripheral neuropathy, as well as therapeutic shoes and inserts under the Diabetic Shoe Bill. Balance Foot & Ankle accepts Medicare.
