Some wounds are too deep for a graft, with bone, tendon or plate lying exposed at the base. A free flap brings living tissue from elsewhere in your body and plugs it into the local blood supply.
Free tissue transfer, often called a free flap, moves skin, fat, muscle or bone from one part of the body to another together with its own artery and vein. Those vessels are then joined to vessels near the wound under an operating microscope, so the transferred tissue keeps a living blood supply from the moment it arrives.
Wounds heal from their edges and from below, so they need a base with blood supply. A skin graft manages that over muscle or healthy fat, but it cannot survive over bare bone, exposed tendon, an implant or an open joint. In those situations tissue has to be brought in, complete with its own circulation, and that is exactly what a free flap does.
The surgeon chooses a donor area whose blood supply is well described and predictable. Skin and fat from the thigh, muscle from the back or inner thigh, and bone from the fibula are among the common choices. The block of tissue is raised on its artery and vein, detached, shaped to fit the defect and stitched in place, then the vessels are joined to a suitable artery and vein beside the wound under the microscope.
Because the flap depends entirely on those two joins, monitoring afterwards is intensive. Nurses check colour, warmth, swelling and refill at short intervals, and any change is reported at once. Our team explains this rhythm before surgery, so the frequent checks feel reassuring rather than alarming.
A free flap suits people who need durable, living cover and who can safely undergo a long operation. Suitability is judged on the wound, on your circulation and on your general health.
The wound is examined, the vessels around it are checked and the donor site is planned. Blood tests, imaging and an anaesthetic review are arranged, and the donor scar is discussed with you.
All dead and infected tissue is removed until only healthy tissue remains. The recipient artery and vein are then found and prepared, since the flap can only survive on healthy vessels.
On the donor site the tissue is lifted carefully on its artery and vein. The blood supply is checked while the flap is still attached, and only then are the vessels divided.
The flap is moved to the wound and its artery and vein are stitched to the recipient vessels under the microscope. Colour and bleeding at the edges confirm that circulation has been established.
The flap is shaped and stitched into the defect without tension, drains are placed and the donor site is closed directly or covered with a graft. Dressings are kept loose around the flap.
You stay in hospital with the area elevated and warm while the flap is checked at short intervals. Movement is limited so that the vessel joins are not disturbed.
Checks become less frequent, drains are removed and dressings are simplified. Sitting out, walking and gentle therapy usually begin, guided by where the flap is.
The flap has settled and swelling is reducing. Light activity is generally allowed, and any weight bearing in the lower limb is progressed on your surgeon advice.
The flap softens and its colour blends better with surrounding skin. A small thinning or scar revision procedure is sometimes done to improve contour or fit in footwear.
A free flap is chosen for durability rather than beauty. The transferred tissue often looks like a patch at first, with a different colour and thickness from the skin around it, and it settles slowly over months. Sensation in the flap is usually reduced. Many people need a later thinning or revision to improve contour. The donor site leaves a scar that is planned but not invisible.
Free flap surgery is reliable in trained hands, yet it is major surgery with a genuine failure rate, so the risks deserve plain discussion.
Once the early danger period passes, most of the work is protecting the flap and letting it mature.
A graft has no blood supply of its own and depends on the wound bed. A free flap arrives with its own artery and vein, which is why it survives over bare bone.
Donor sites are chosen because the body copes with their loss. Some stiffness or weakness can occur, and it is discussed before surgery rather than discovered afterwards.
The vessel joins are most vulnerable in the first days. After that period the flap develops connections with surrounding tissue and becomes far more secure.
A flap usually looks like a patch to begin with. Colour and contour improve over months, and revision surgery can refine it, though a difference commonly remains.
Elegance Clinic in Surat performs free flap reconstruction with a microsurgery trained team and structured flap monitoring after surgery. Dr. Ashutosh Shah explains the donor site trade and the realistic appearance before you decide.
Free flap reconstruction is a long operation with two surgical fields, specialised instruments and close monitoring afterwards, so the cost sits above simpler wound cover. The band below reflects that range rather than a single price.
After assessment our team gives you a written estimate covering theatre, implants, hospital stay, dressings, medicines and follow up. Where the flap is needed after trauma or tumour surgery, insurance and government scheme approvals are usually possible and the front desk helps you start them.
These are the questions that come up most often in consultation. If yours is not here, send it on WhatsApp and the team will reply, usually the same day.
Ask your question →Free flap reconstruction generally falls within a band of Rs 1.8L to Rs 4.5L, varying with the flap chosen, the length of surgery, implants and hospital stay. The figure is case based, and a written estimate is shared after assessment and before admission.
A graft needs a wound bed with its own blood supply, so it cannot survive over bare bone, exposed tendon, an implant or an open joint. A flap brings its own artery and vein, which is what allows it to live in those places.
It is major surgery under general anaesthesia, and fitness is checked carefully first. The main specific risk is clotting in the joined vessels, which is why monitoring during the first days is frequent and why an early return to theatre is sometimes needed.
Plan for about a week in hospital, then several weeks of protected activity. Light routine often resumes around six to eight weeks, while the flap continues to soften and settle for many months. Recovery can vary with the site and the original injury.
It usually looks like a patch at first, with a different colour and thickness from nearby skin. Appearance improves over months, and a thinning or revision procedure can refine it. Sensation in the transferred tissue stays reduced.
People with severe vascular disease and no suitable vessel to join, those with an infected or dead wound bed that has not been cleared, and anyone unwilling to stop smoking are poor candidates. A simpler local option is preferred when it can do the job.
The wound is examined, circulation is assessed and imaging may be arranged. Donor site options, the likely appearance, the risks and the alternatives are explained, and a written estimate is provided before any date is fixed.
Each technique below has its own page explaining how it works and when it is chosen.
