Soft-Tissue Reconstruction & Regenerative Closure
From minimally invasive epidermal cell harvesting to free-flap reconstruction — closing what debridement left open, with techniques matched to each defect and patient.
Patients with residual soft-tissue defects after infection control and revascularization — too large for secondary-intent closure — in whom infection is controlled, blood supply is adequate, and glycemic control is established. Also includes early-stage wounds where regenerative techniques (autologous cell therapy, topical biologics) can accelerate closure before a defect becomes complex.
When infection is controlled and circulation is restored, what often remains is a soft-tissue defect that the body cannot close on its own. Our reconstructive team selects the least-invasive technique that will achieve durable closure — starting with biological options and escalating to surgical flaps only when needed.
Micro-dome epidermal harvesting
Standard split-skin grafting removes a dermal-layer donor patch that leaves a visible wound. Micro-dome harvesting uses a specialized device to extract ultra-thin 0.06 mm epidermal blisters from a very small donor site — typically the thigh. The 1 cm² of donor skin is expanded into a 40 cm² mesh, applied to the prepared wound, and secured. Donor-site healing is typically complete in 3–5 days with minimal scarring.
- Done under local anaesthesia — no general anaesthesia required for most patients
- Graft secured with biological adhesive; first dressing change at day 5
- Suitable for wounds up to ~200 cm² with a single donor harvest
Autologous cell therapy (BM-MNC)
For ischemic wounds where no targetable vessel exists, bone-marrow mononuclear cells (BM-MNC) — harvested from the patient's iliac crest and concentrated — are injected into the ischemic foot tissue. These cells release angiogenic growth factors locally, stimulating capillary ingrowth over 4–8 weeks. The procedure is done under sedation and is combined with ongoing wound care.
Rotational and free-flap reconstruction
For larger defects involving the plantar surface, heel, or forefoot, rotational or free-flap reconstruction moves well-vascularized tissue to provide durable, load-bearing coverage. Our microsurgery team performs free-flap anastomoses to pedal and tibial vessels — often in patients whose vessel caliber would be considered marginal by general microsurgery teams unfamiliar with the diabetic foot.
Reconstructive flap surgery is available globally. What differs at our centers is the range of less-invasive alternatives used before flap surgery becomes necessary. Micro-dome epidermal harvesting extracts ultra-thin 0.06 mm grafts under local anaesthesia, expanding 1 cm² of donor skin to cover 40 cm² of recipient wound — a technique requiring specialized equipment and training not widely deployed at general hospitals. Autologous bone-marrow mononuclear cell (BM-MNC) injection into the ischemic foot as an adjunct to wound care is performed routinely at our centers, while still experimental at most Western institutions.
