Total contact casting (TCC) — a well-molded fiberglass or plaster cast applied in contact with all surfaces of the plantar foot to distribute weight-bearing pressure uniformly — is the gold standard off-loading device for both diabetic plantar neuropathic ulcers and acute Charcot neuroarthropathy. Understanding the TCC application protocol, monitoring requirements, and cast change schedule is essential for achieving optimal outcomes with this highly effective but technically demanding intervention.

Indications and Contraindications

TCC indications: Grade 1–2 plantar neuropathic ulcers in diabetic patients (Wagner classification); acute and subacute Charcot neuroarthropathy (Eichenholtz stage 0–II) requiring non-weight-bearing or protected weight-bearing immobilization; and midfoot Charcot deformity with recurrent ulceration. TCC contraindications: active deep infection or osteomyelitis (requires surgical debridement before casting); significant wound depth with undermining (heel ulcers — TCC is high-risk at the heel); and inadequate skin quality (skin fragility syndromes, severe chronic venous insufficiency with weeping dermatitis). The removable cast walker (RCW) — while easier to apply — produces worse ulcer healing rates than TCC in randomized trials because patient compliance with non-weight-bearing is dramatically lower with removable devices.

TCC Application and Change Protocol

TCC application: the foot is positioned at 90 degrees of dorsiflexion (neutral position); all bony prominences (malleoli, dorsal foot) are padded with felt or foam; a well-molded stockinette is applied; a minimum of two layers of fiberglass casting material are applied in total contact with the plantar foot surface — this equal distribution of plantar pressure (rather than focal loading) is the mechanism of ulcer healing. Cast change schedule: weekly for ulcer patients (to clean the wound and assess healing) and every 1–2 weeks for Charcot patients. Casting duration: until wound closure for neuropathic ulcers (average 5–7 weeks); until skin temperature normalized and maintained <2°C differential between feet for Charcot (typically 3–6 months). Dr. Biernacki at Balance Foot & Ankle applies and manages total contact casts for diabetic foot ulcers and Charcot neuroarthropathy.

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.
