of the lower jaw using vascularized (having its own intact blood supply, so tissue survives transfer) bone flaps, bone grafts, or titanium plates.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/) Vascularized fibular grafting is the standard choice for defects larger than 6 cm, for failed nonvascularized grafting, for infected nonunion, and after tumor resection when postoperative radiation is anticipated.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/)\n\n| Key fact | Value |\n|---|---|\n| Fibula bone available | 22–26 cm of dense cortical bone in adults, the longest bone transferable by microsurgical technique [2](https://www.sciencedirect.com/science/article/abs/pii/S0020138319306631) |\n| Fibula height | Approximately 13 mm, versus native mandibular height above 3–4 cm [2](https://www.sciencedirect.com/science/article/abs/pii/S0020138319306631) |\n| Share of free osseous flaps | 982 of 1,353 patients (72.6%) in a systematic review received fibular flaps [2](https://www.sciencedirect.com/science/article/abs/pii/S0020138319306631) |\n| Flap survival (fibula) | 94.50% in a network meta-analysis of 22 studies (1,513 patients) [3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457); published series range 87–100% [4](https://head-face-med.biomedcentral.com/articles/10.1186/s13005-021-00293-z) |\n| Most common complication | Plate-related exposure or fracture, 26.8% [5](https://pmc.ncbi.nlm.nih.gov/articles/PMC9391286/) |\n| Dental implant success in fibula grafts | 92% pooled (95% graft success); 2.91× higher failure than implants in natural bone [6](https://www.springermedizin.de/outcomes-and-influential-factors-in-functional-and-dental-rehabi/25587262) |\n| Effect of virtual surgical planning | Ischemia time reduced by 1.55 h (95% CI 1.22–1.87) and total operative time by 1.01 h (95% CI 0.80–1.23) [7](https://link.springer.com/article/10.1186/s12885-025-13505-5) |\n\n## How it works\n\nThe fibula has a dual intraosseous and segmental blood supply from the peroneal artery, which allows the bone to be cut into several segments, each remaining perfused, and shaped to the mandibular arch.[2](https://www.sciencedirect.com/science/article/abs/pii/S0020138319306631) • [8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx)\n\n## How it is done\n\n**Planning.** Preoperative workup uses bilateral lower-extremity CT angiography and facial CT for virtual surgical planning (VSP), which produces a fibula cutting guide, a mandibular resection guide, and a patient-specific reconstruction plate.[8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx) Images should be obtained no more than 3 weeks before surgery (2 weeks is considered optimal) to keep oncological margins accurate, and a web conference with a biomedical engineer is held about 2 weeks preoperatively.[9](https://fomm.amegroups.org/article/view/42414/html) The CT must confirm permeability of the three leg vascular axes.[9](https://fomm.amegroups.org/article/view/42414/html)\n\n**Harvest.** The central portion of the fibula is harvested with a tourniquet inflated to 250 mm Hg,[8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx) preserving the distal 5 cm for ankle stability and the proximal 5 cm to protect the common peroneal nerve;[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/) osteotomies must maintain 7 cm of proximal and distal fibula in the VSP protocol.[8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx) Doppler identifies perforators about 1 cm posterior to the mid-lateral line at the junction of the middle and distal thirds.[8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx) The distal fibula can provide up to 15 cm of vessel length for a longer pedicle (the blood-vessel stalk supplying a transferred tissue flap).[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/)\n\n**Shaping and fixation.** Fibula osteotomies are performed with piezosurgery under cutting guides before the pedicle is clamped, which reduces flap ischemia time compared with freehand modeling.[9](https://fomm.amegroups.org/article/view/42414/html) The segments are fixated to a 2.7 mm locking reconstruction plate with unicortical locking screws before the peroneal pedicle is divided.[8](https://journals.lww.com/prsgo/fulltext/2023/11000/free_fibula_flap_mandibular_reconstruction__a.1.aspx) In the neck, the facial vessels are commonly used for anastomosis, with the superior thyroid, transverse cervical, superficial temporal, and external carotid arteries as alternatives and the external jugular vein as a secondary venous option; a 2 mm reconstruction bar is a common alternative fixation, and hardware should not be changed once vascular anastomosis is complete.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/)\n\n**Dental rehabilitation.** In the \"jaw in a day\" concept, dental implants are placed into the fibula during flap transfer under the same anesthesia, with a provisional prosthesis fitted to the neomandible to expedite oral feeding.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/)\n\n## Origin\n\nThe free vascularized bone flap was reported by G. [Ian Taylor](https://www.edgepedia.org/ian-taylor), Graeme D. H. Miller, and Frank J. Ham in 1975 in *Plastic & Reconstructive Surgery*, using the fibula to repair a post-traumatic tibial defect.[4](https://head-face-med.biomedcentral.com/articles/10.1186/s13005-021-00293-z) • [10](https://doi.org/10.1097/00006534-197505000-00002) Taylor and Neil Watson reported a free groin skin and iliac bone flap on the superficial circumflex iliac artery in 1978,[11](https://doi.org/10.1097/00006534-197804000-00002) and Taylor, Paul Townsend, and Russell Corlett described the deep circumflex iliac artery (DCIA) as the preferred supply for free groin flaps in 1979.[12](https://doi.org/10.1097/00006534-197912000-00001) Neil Ford Jones and colleagues described the \"double barrel\" free vascularized fibular bone graft in 1988.[13](https://doi.org/10.1097/00006534-198803000-00011) David A. Hidalgo reported mandibular reconstruction with the fibula free flap in 12 patients in 1989: twelve segmental defects averaging 13.5 cm, flap survival in all patients, primary healing of all osteotomies, miniplate fixation in 11 of 12, and at least two osteotomies per graft.[14](https://europepmc.org/article/MED/2734406) Ian M. Zlotolow and colleagues reported secondary osseointegrated dental implants in fibula-reconstructed mandibles in 1992.[15](https://doi.org/10.1016/s0002-9610%2805%2980733-0) [John Yoo](https://www.edgepedia.org/john-yoo) and colleagues described the scapular tip free flap for mandibular reconstruction in 2012,[16](https://doi.org/10.1002/hed.23065) G. Succo and colleagues published a step-by-step VSP technique with patient-specific guides in 2014,[17](https://doi.org/10.1007/s00405-014-3078-3) and Bo-Yeon Hwang, Kwantae Noh, and Jung-Woo Lee reported a 3D-bioprinted patient-specific polycaprolactone implant combined with a fibula flap in 2023.[18](https://doi.org/10.3390/bioengineering10060684)\n\n## Variants\n\n**Double-barrel fibula.** The flap is folded over its own base, maintaining the original vascularization, to double the vertical height and solve the height discrepancy of the single-barrel fibula.[4](https://head-face-med.biomedcentral.com/articles/10.1186/s13005-021-00293-z) A 2024 systematic review of 17 studies (245 patients, 402 implants) found 98.3% flap survival and a 1.74% implant failure rate over a mean 34.3 months.[19](https://www.mdpi.com/2077-0383/13/12/3547) The technique is limited to defects not more than 8 cm for fully dentally rehabilitated outcomes.[3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457)\n\n**Scapular tip.** The scapular tip free flap offers pedicle lengths of up to 17 cm and suits linear defects with complex soft-tissue requirements;[20](https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/1671203) the scapula flap cannot be used for total mandibular reconstruction because of limited bone stock.[3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457)\n\n**DCIA iliac crest.** The iliac crest provides bone that mimics the vertical height of the native mandible and is described as ideal for osseointegration,[3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457) • [21](https://doi.org/10.1097/prs.0000000000002040) but in a single-center comparison of 163 reconstructions the DCIA group had the highest flap loss rate (\\( p = 0.001 \\)) and the most severe donor-site complications, including chronic pain, hernias, gait problems, and fractures of the anterior superior iliac spine.[22](https://journals.sagepub.com/doi/10.1177/1457496918772365)\n\n**Selection.** A defect-based algorithm assigns lateral bony defects without soft-tissue loss to the ilium, lateral defects with small skin or mucosal defects to the fibula, lateral defects with extensive or through-and-through soft-tissue loss to the scapula, and anterior defects to the fibula.[3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457) Combined rates of anatomic anomalies and peripheral vascular disease precluding safe fibula harvest are reported at 21–25%.[20](https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/1671203)\n\n## Applications\n\nIndications include defects larger than 6 cm, failed nonvascularized grafting, infected nonunion, and segmental defects after tumor resection when postoperative radiation is anticipated.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/) Flap survival should not drive donor-site selection: a network meta-analysis of 22 studies found survival of 94.50% (fibula), 93.12% (DCIA), 97% (scapula), and 95.95% (osteocutaneous radial forearm), with no statistically significant differences.[3](https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257457) Pooled implant success in fibula grafts is 92%, but radiated bone carries a 2.29× higher implant failure risk (\\( p = 0.03 \\)), smokers a 3.16× higher risk (\\( p = 0.04 \\)), and success declines over time, from 93% at 1 year to 69% at 9 years in one included study.[6](https://www.springermedizin.de/outcomes-and-influential-factors-in-functional-and-dental-rehabi/25587262)\n\n## Limitations and alternatives\n\n**Complications.** Across studies of fibula-flap mandibular reconstruction, the most common complication is plate-related exposure or fracture (26.8%), followed by wound dehiscence (14.0%), malunion or non-union (11.7%), fistula formation (8.6%), infection (6.8%), partial flap loss (7.7%), and total flap loss (6.0%).[5](https://pmc.ncbi.nlm.nih.gov/articles/PMC9391286/) Vascular compromise affects about 4% of free-flap reconstructions in one large study, with salvage rates exceeding 50% when return to the operating room occurs within 3 hours.[1](https://www.ncbi.nlm.nih.gov/books/NBK564337/) • [27](https://pubmed.ncbi.nlm.nih.gov/29280859/)\n\n**Fixation choice.** A meta-analysis of 16 studies (1,513 patients) found mini-plate fixation associated with more plate-related complications (32.5% vs 18.8%, \\( p < 0.01 \\)), fistula (15.8% vs 4.7%), total flap loss (9.4% vs 4.7%), and re-operation for vascular compromise (13.3% vs 4.0%) than reconstruction bars, though random-effects modeling found no significant difference in plate-related complications (OR 2.02, 95% CI 0.87–4.71, \\( p = 0.10 \\)).[5](https://pmc.ncbi.nlm.nih.gov/articles/PMC9391286/)\n\n**Plates alone.** Bridging-plate reconstruction is faster and avoids donor-site morbidity, but a meta-analysis of 2,379 patients found plate extrusion risk of 20% with soft tissue plus plate versus 10% with osseous reconstruction, and revision surgery twice as often (32% vs 14%).[23](https://aao-hnsfjournals.onlinelibrary.wiley.com/doi/10.1177/0194599820949223) The evidence on plate exposure conflicts: the 335-patient cohort with patient-specific 3D-printed titanium plates found no significant difference between bridging plates and osseous reconstruction (exposure 21.6% vs 24.8%, \\( p = 0.669 \\)),[24](https://pmc.ncbi.nlm.nih.gov/articles/PMC12812072/) whereas the Bauer meta-analysis reported a significant difference (20% vs 10%).[23](https://aao-hnsfjournals.onlinelibrary.wiley.com/doi/10.1177/0194599820949223) That cohort supports a two-stage approach, initial bridging plate for frail patients (mean age 74.4 vs 63.4 years) with secondary vascularized bone later for dental rehabilitation.[24](https://pmc.ncbi.nlm.nih.gov/articles/PMC12812072/)\n\n**Alloplastic implants.** In 16 patients, 3D-printed PEEK implants gave satisfactory outcomes in 6 of 8 with significantly shorter operative time than free fibula flap (\\( p < 0.05 \\)), but 2 required explantation for uncontrolled infection, with fibula flap as successful salvage; the PEEK implants were not designed to support dental implantation.[25](https://www.frontiersin.org/journals/oncology/articles/10.3389/fonc.2025.1656914/full)\n\n**Digital developments.** Meta-analyses found no statistically significant differences in flap loss, fistula, or infection between VSP and conventional reconstruction, despite VSP's time savings and accuracy gains.[9](https://fomm.amegroups.org/article/view/42414/html) A partially adjustable guide system (ReconGuide) achieves comparable surface matching (median RMSE 2.9 mm vs 3.1 mm for CAD/CAM) without preoperative virtual planning.[26](https://www.frontiersin.org/journals/oncology/articles/10.3389/fonc.2023.1167071/full) [Distraction osteogenesis](https://www.edgepedia.org/distraction-osteogenesis) is possible with both scapula and fibula.[20](https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/1671203)\n\n## References\n\n1.
