Reconstructive Surgery
Vascularized bone free flap reconstruction transfers living bone and its blood vessels to rebuild a damaged or missing section of bone.
How is this different from a bone graft?
The transferred bone comes with blood vessels that are reconnected at the reconstruction site.
A conventional bone graft does not have its own surgically reconnected circulation. It relies on the surrounding tissue to establish a blood supply.
Where does the bone come from?
Common donor areas include the fibula in the lower leg, the pelvis, and the shoulder blade.
The choice depends on the length and shape of bone needed, whether skin or muscle is also needed, and the health of the donor area.
Is this a single operation?
It may be one major operation within a longer reconstruction plan.
Additional procedures, rehabilitation, or dental restoration may be needed. Your surgeon should explain the likely stages before treatment.
01 · Overview
This operation replaces a substantial bone defect with living bone taken from another part of your body. The surgeon uses microsurgery to connect the flap's artery and vein to blood vessels near the defect. Skin, muscle, or other tissue may travel with the bone when the area needs more than structural support. [1]
Reconstruction may be considered after tumor removal, severe injury, infection treatment, or a bone-healing problem. Common applications include rebuilding the jaw or a long bone in an arm or leg. Infection control, cancer treatment, and the condition of nearby tissue can influence when reconstruction is appropriate. [1]
A free flap is completely detached from its donor area before its blood vessels are reconnected. This differs from a pedicled flap, which stays attached to its original circulation, and from a conventional bone graft. Plates, screws, or other fixation usually hold the reconstruction in place while the bone joins the surrounding skeleton. [1]
Bone with a reconnected blood supply may be useful for a large defect or an area with damaged surrounding tissue. It still needs to unite with the remaining bone. The added surgical complexity is not necessary for every defect.
No. Blood-flow monitoring checks whether the transferred tissue is surviving. Bone union is a separate process assessed over time through examinations and imaging.
02 · Concerns & Goals
A major bone defect can affect movement, support, appearance, or everyday activities. The goals depend on the area being rebuilt and what matters most to you.
A large gap may need living bone to restore continuity and support after injury or tissue removal.
Some bones fail to join after earlier treatment. Your team will assess infection, stability, circulation, and other reasons for delayed healing.
Depending on the site, reconstruction may aim to support walking, arm use, chewing, swallowing, or other daily tasks.
A defect may affect body contour and the skin or muscle over the bone. A combined-tissue flap may address several needs together.
03 · Options
These are examples of donor-flap choices, not interchangeable treatments. Your reconstructive surgeon will recommend an approach based on the defect, blood vessels, and donor-site health.
Uses a segment of the smaller bone in the lower leg.
Uses bone from the shoulder-blade region.
Uses bone from the pelvic rim.
Uses a smaller or more specialized donor site for selected defects.
Donor-site selection requires an individualized assessment. A flap that is useful for one person's jaw or limb may not be appropriate for another person's reconstruction. [1].
Your team may use imaging of the defect and donor area, including blood-vessel imaging when appropriate. Some reconstructions use computer-assisted planning, cutting guides, or customized fixation.
Sometimes. The bone position, soft tissue, bite, radiation history, and overall treatment plan affect whether and when implants are possible. Dental rehabilitation may require separate procedures and costs.
04 · Results
The goal is living bone that joins the remaining skeleton.
Recovery depends on more than the transferred bone.
Reconstruction may restore contour without recreating the original anatomy exactly.
Flap survival, bone union, and functional recovery are separate milestones. Your team should explain how each will be assessed. [1]
05 · Recovery
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery involves both the reconstructed area and the donor site. The hospital stay and home-care plan vary substantially between jaw, arm, and leg reconstruction.
Step 1 · Day of surgery
The team transfers and secures the bone, reconnects its vessels, and closes or covers both surgical areas. After anesthesia, monitoring focuses on circulation, breathing, pain, and overall stability.
Step 2 · First several days or longer
Staff check the flap frequently. Drains, dressings, splints, feeding support, or breathing support may be needed depending on the site. Therapy and safe movement begin when the team considers them appropriate.
Step 3 · Following discharge
Your team provides specific wound-care, diet, positioning, and activity guidance. Follow-up checks address both sites and any equipment or support you need at home.
Step 4 · Over subsequent months
Examinations and imaging guide changes in loading and activity. Rehabilitation and any later restorative procedures follow your progress, not a fixed calendar.
Follow your surgical team's instructions rather than a general recovery schedule. Ask your surgical team whether compresses are appropriate and exactly how to use them.
A clot or another circulation problem can threaten the flap. Early recognition may allow urgent treatment, sometimes including another operation. Frequent checks are especially important early in recovery.
Many people regain useful function, but recovery varies. Persistent pain, weakness, altered sensation, swelling, or activity limits are possible. Ask how the proposed donor site could affect your work and interests.
06 · Safety
Pain, swelling, bruising, fatigue, scars, and temporary changes in movement or sensation can occur at both surgical sites. Your team should explain what is expected for your reconstruction and which changes need prompt assessment.
Clotting or problems with the connected vessels can cause partial or complete tissue loss. Urgent surgery or another reconstruction may be needed.
Infection, delayed closure, or tissue breakdown may require antibiotics, drainage, wound treatment, or further surgery.
The bone may heal slowly, fail to unite, fracture, or heal in an unfavorable position. Plates or screws may loosen, become exposed, or need removal.
Possible problems include weakness, pain, numbness, wound difficulty, and site-specific issues such as fracture, walking changes, or hernia.
Bleeding, fluid collections, blood clots in the legs or lungs, and anesthesia-related complications can occur during a major operation and recovery.
Scarring, asymmetry, altered sensation, or lasting limits in movement, chewing, speech, or swallowing may remain, depending on the reconstruction.
Discuss these risks and your individual health history with your surgeon. [1]
07 · Costs
Compare written estimates for the same planned scope, including the donor flap, hospital care, and expected stages. Coverage and out-of-pocket costs depend on your insurance benefits, authorization, and participating providers.
Surgeon
Reconstruction, donor-site surgery, microsurgery, fixation, and any other planned surgical work.
Ask your surgeonAsk which surgeons and procedures are included and whether later operations are estimated separately.
Facility
Anesthesia, operating-room services, hospitalization, and postoperative monitoring.
Ask your surgeonAsk about separate bills, network status, and how a longer admission or additional surgery would be handled.
Supplies
Potential charges for dressings, equipment, imaging, follow-up, rehabilitation, and dental restoration when relevant.
Ask your surgeonConfirm what is included, what is billed separately, and which services need authorization.
TRC
Any separately listed care-coordination or patient-support services.
Ask TRCAsk whether these services apply to your plan, what they include, and whether they are optional or covered by insurance.
Your written estimate should explain the services included, any separate charges, and payment terms.
08 · Questions
In this procedure, the living bone flap usually comes from your own body. Donor bone used in some conventional grafts is a different approach and does not have surgically reconnected circulation.
A flap made from your own tissue does not require anti-rejection medicine. Your team may prescribe other medicines for reasons such as infection prevention, pain control, or clot prevention.
Sometimes it can. Timing depends on the tumor operation, your health, tissue condition, and other planned treatment. Some people need staged reconstruction.
The team may urgently explore the blood-vessel connections. If the tissue cannot be saved, further wound care and a different reconstruction may be needed. Ask about backup options before surgery.
