Total-Contact Casts: Healing Ulcers Fast—with Remarkably Low Reported Thrombosis Risk
Summary: Total-contact casts (TCCs) remain the gold standard for offloading diabetic foot ulcers in tolerant patients, alongside irremovable devices, but concerns about immobility-related venous thrombosis have limited use. A recent systematic review reports remarkably low DVT rates (~0.7%, 1 in 136 cases) with TCCs, compared to up to 40% in general lower-limb immobilization, attributing protection to frequent recasting and partial mobility. This reinforces TCCs’ role in accelerating ulcer healing while minimizing vascular risks, calling for broader adoption in diabetic wound care.
Key Highlights:
- TCCs or irremovable casts are top for offloading diabetic foot ulcers in suitable patients.
- DVT prevalence with TCCs: ~0.7% (1/136 cases), far below 40% in standard immobilization.
- Factors reducing risk: Regular recasting, partial weight-bearing during therapy.
- Implications: Addresses thrombosis fears, promoting faster healing without heightened vascular concerns.
