Part 5 of 9 in Plastic Surgery: From Reconstructions to Aesthetics

Reconstructing Bone Defects with the Vascularised Free Fibula

July 27, 2025

The vascularised free fibula, a segment of the calf bone transferred with its own blood supply intact, reconstructs bone defects across the body that would otherwise leave a patient with major functional loss. For mandible reconstruction after ameloblastoma resection, a free fibula flap rebuilt the whole jaw with good contour, and dental implants were placed at the same sitting in one case, giving the patient a functioning bite again.

Preserving growth plates in children

For a child with osteosarcoma of the lower humerus involving the growth plate, where oncologic surgery required removing the bone segment along with the growth plate, the reconstruction used the opposite leg's fibula including its own growth plate and metaphysis, based on dual blood supply from the peroneal and anterior tibial arteries, specifically to avoid future growth discrepancy between the limbs. Two years later, the child walks without shortening and with good range of motion.

Restoring blood supply after avascular necrosis

For a 12-year-old with post-traumatic avascular necrosis of the femoral head, a vascularised fibula graft placed inside the reamed femoral head restored blood supply to the area. The result was full, pain-free range of motion with no leg-length discrepancy, the child was recorded walking and jumping normally on follow-up. Across all these cases, the underlying principle is the same: a free fibula flap carries its own living blood supply, giving it healing potential that a non-vascularised bone graft cannot match.

FROM THE LIVE Q&A

DR

Dr. Dinawal (Ethiopia)

What is the golden time for an amputated body part to be reconstructed and have a good outcome, and does it differ by body part?

PK

Dr. Pradeep Kumar Singh

Yes, it varies significantly. For the arm, the golden period is 4 hours. For the forearm, 6 hours. For fingers, replantation can be attempted even at 8-10 hours. Early in his practice, proximal replantation was attempted at 10-12 hours, but the post-operative course was unpredictable enough that the lesson learned was not to attempt proximal replantation beyond 4, at most 6, hours.

Frequently Asked Questions

In a cross-border setting, immediate replantation within the golden window often isn't feasible. Is there still hope for these patients if they reach India two to six months later, can meaningful improvement still be achieved?

Yes. For fingers, toe-to-hand transfer can restore good functional benefit even when the original finger wasn't salvaged in time. A few centres, though not this one yet, have started cadaveric hand transplant, though this is legally restricted in India to Indian citizens only, ruling it out for international patients. This centre is planning to start a hand transplant programme within about a year to a year and a half. In the meantime, options include toe transfer, cosmetic prostheses including osseointegrated ones, and myoelectric bionic hands.

What are the pre-surgical evaluations for brachial plexus injuries?

Three things: clinical examination first, to map out the deformity pattern and plan; nerve conduction study and EMG, to identify how many donor nerves or muscles are available for transfer; and MRI, to map the brachial plexus itself. Both birth-related (obstetric) and adult traumatic or oncological brachial plexus injuries are managed with this same three-part workup.

What is the lowest age limit for aesthetic surgery?

For facial procedures, growth is considered complete by around 15-16 years, so a 15-year-old's face is functionally comparable to an adult's for surgical purposes, with parental consent sufficient at that age. For the rest of the body, 17-18 is considered the optimum age, since patients are mature enough by then to properly weigh their own body image and understand the implications of the procedure.

In real time, how should our doctor colleagues in Africa triage a case, based on which parameters should they identify that this looks fit for reconstructive surgery versus purely aesthetic, and at what point should they send the case note to you?

Plastic surgery was originally developed for reconstruction, so any wound that hasn't healed in three weeks, whether traumatic, burn, or post-cancer resection, needs plastic surgery intervention and can be referred directly. Any congenital defect, a hand anomaly, cleft, or other soft tissue deformity, should also be sent directly. Cancerous skin lesions, where excision and reconstruction go together, are handled by plastic surgery too. And any leg oedema that doesn't resolve with elevation and conservative management is a specific trigger for lymphoedema referral. These are the practical trigger points to know.

What are the cost implications of these surgeries?

Costs are considerably lower than in the Western world. Microvascular reconstructions range from roughly $6,000 to $9,000-10,000 depending on the number of procedures required and typically a 4-5 day hospital stay. Purely cosmetic procedures range from $2,000 to $7,000; a bundled "mommy makeover" package (breast reduction, liposuction and tummy tuck) is offered at a fixed $7,000.

What is a vascularised free fibula flap used for?

Reconstructing major bone defects, such as the jaw after tumour resection, long bone defects after cancer surgery, or the femoral head after avascular necrosis, using a segment of the calf bone transferred with its own intact blood supply.

How is growth preserved when reconstructing a child's bone after tumour resection?

By using a fibula segment that includes its own growth plate and metaphysis, based on dual blood supply from the peroneal and anterior tibial arteries, specifically to avoid a future growth discrepancy between the limbs.
