Plantar ulcers that do not heal in patients with diabetes and peripheral sensory neuropathy have been shown to be precursors of lower extremity amputation. The total contact cast is considered by many authorities to be the most effective technique for healing of wounds in the neuropathic extremity, yet it still is not widely used in clinical practice. Use of the total contact cast allows mobilization and results in diminished edema and decreased pressure over the ulcerated area. Complete healing usually occurs in eight weeks or less. Total contact casting with careful follow-up should be considered as a useful modality for healing plantar ulcers in diabetic patients with neuropathy of the extremities.
