Vascularized fibular graft for reconstruction after resection of aggressive benign and malignant bone tumors.

From 1982 to 1991, 19 patients at Nara Medical University, Kashihara, Japan, underwent resection of aggressive benign and malignant bone tumors, with limb salvage and reconstruction by free vascularized fibula grafts. The patients were followed up for an average of 54 months. The reconstructed site was the jaw in 6 cases, upper extremity in 3, spine in 1, pelvis in 2, and lower extremity in 7. Six patients had aggressive benign lesions, and 13 had malignant lesions. The sizes of the resultant bone defect ranged from 6 to 20 cm, and the lengths of fibular used ranged from 8 to 24 cm. The average time to union was 4.1 months (2-9 months) in the extremities and pelvis. Local recurrence was observed in 3 cases, for whom vascularized fibula grafts were performed for recurrent tumors. In cases of primary untreated tumors, no recurrences occurred. Therefore, this procedure should be performed at the time of primary operation after extensive resection of an aggressive benign or malignant bone tumor.     

The use of free vascularized fibular grafts in skeletal reconstruction for bone tumors in children

The reconstruction of large skeletal defects in children following resection of a bone tumor presents a unique challenge to the orthopaedic surgeon. Issues in this population that are not present in the adult population include significant remaining growth potential, the desire for biologic preservation of the joint surface, and the need for a long-term viable reconstruction in patients who are anticipated to survive for decades. The use of a free vascularized fibular graft, supplied by the peroneal vessels in intercalary fibular grafts and the anterior tibial vessels in proximal fibular grafts, has been shown to provide biologic reconstruction that successfully addresses these issues in the pediatric population. Specific techniques are applied in the upper and lower extremity to provide long-term excellent functional results. Experience in microvascular surgery and careful postoperative care are required for the success of these procedures.

Vascularized fibular graft for bone defects after wide resection of musculoskeletal tumors

Background  

In reconstruction by vascularized fibular graft (VFG) after wide resection of musculoskeletal tumors, there are problems such as the method of fixing the fibular graft, the period of achieving bone union, and the avoidance of postoperative fractures. We have performed VFG on 19 cases over a 30-year period. We have investigated these problems and now report the results.     

Vascularised free fibular flap in bone resection and reconstruction.

This paper compares allograft alone and in combination with vascularised free fibular flaps (FFF) to reconstruct long bone defects after tumour excision. We present 33 cases, 21 of these patients had reconstruction with an allograft alone as the initial procedure. Nine patients underwent reconstruction with FFF plus allograft plus iliac crest bone graft (ICG), two patients underwent reconstruction with a FFF and ICG and one patient underwent reconstruction with an allograft, a pedicled fibular flap and a FFF. The allograft was obtained from the Queensland Bone Bank and had been irradiated to 25 000Gy. In our experience (N=21) the complication rates with allograft alone were: delayed union 3, nonunion 7, fractured allograft 6, infection requiring resection of the allograft 3, other infections 2. The revision rate was 48% (10 cases of which five required a free fibular flap) and an average of 1.8 revision procedures were required. In the lower limb cases, the mean time to full weightbearing was 20 months and 40% were full weightbearing at 18 months. We felt that the high complication rate compared with other series may have been related to the irradiation of the graft. FFFs were used in 18 cases, 12 cases were primary reconstructions and six were revision reconstructions. The mean fibular length was 19.4 cm (range 10-29 cm). There were no flap losses and the FFF united at both ends of 11 of 12 primary reconstruction cases. One case had nonunion at one end, giving a union rate of 96% (23 of 24 junctions). When a FFF was used in combination with an allograft as a primary reconstruction, the allograft nonunion rate was 50% (five of 10 cases). The mean time to full weightbearing in the lower limb cases was 7.5 months and 100% were full weightbearing at 18 months. The FFF hastens time to full weightbearing but does not appear to affect the complication rates of allograft. The number of revision procedures required is reduced in the presence of a FFF and is the latter is a useful technique for the salvage of refractory cases.     

Microsurgical reconstruction of lower limb bone defects following tumor resection using vascularized fibula osteoseptocutaneous flap

This study included 25 patients with lower limb tumors who had wide local resection and reconstruction by vascularized fibula osteoseptocutaneous flap, and who had their surgery performed at least 24 months before the end of the study. The average age at operation was 23.5 years. Twenty-three tumors were malignant;16 were staged as high-grade sarcomas (stage IIA, stage IIB, and Ewing's sarcoma). Tumor volume averaged 293.2 cc (range, 41.4-860). The resulting defect after tumor resection averaged 16 cm (range, 9-20 cm). The fibula was inserted as a single strut in 21 patients, and as a double-barrel construct in 4 patients. Fixation was augmented by interlocking nail in 11 cases, bridge plate in 9 cases, and external fixator in 5 cases. Twenty-four (96%) flaps survived. All grafts united in an average period of 4.5 months (range, 3-8 months) after transfer. Two secondary procedures were necessary to achieve graft union. Full weight bearing was possible after an average period of 7.5 months (range, 5-14 months). Significant hypertrophy (> or =30% of original fibular diameter) occurred in 85% of patients after an average period of 10 months from the index operation. In the latest follow-up radiographs (mean, 32 months), the degree of hypertrophy averaged 90% (range, 30-200%). Graft fracture occurred in three patients, and all healed conservatively. The Musculoskeletal Tumor Society rating score (MTSRS) averaged 21.2 points at the end of the first postoperative year, and 23.6 at the end of the study.     

Free vascularized fibular graft: a versatile graft for reconstruction of large skeletal defects and revascularization of necrotic bone.

The microvascular transfer of a fibular graft that was initially introduced for the treatment of massive bone loss in the appendicular skeleton has more recently found another useful application in the management of the osteonecrosis of the femoral head. Since 1989, we have successfully used the free vascularized fibula in two patients with segmental bone loss, one in the forearm and the other in the distal femur. We have also attempted revascularization of the femoral head in fifteen patients (eighteen hips) with osteonecrosis. Although our follow-up is short, the results have been encouraging and this method is now the treatment of choice in the early stages of the disease.

Metatarsal reconstruction with use of free vascularized osteomyocutaneous fibular grafts following resection of malignant tumors of the midfoot. A series of six cases

BACKGROUND: Bone and soft-tissue sarcomas are uncommon, and their location in the foot is extremely rare. While limb salvage has become the standard of care in the treatment of sarcoma in an extremity, the unique anatomy of the foot presents challenges in reconstructing a viable and functional limb. METHODS: Between 1998 and 2005, we used free microvascularized osteomyocutaneous fibular grafts to reconstruct the defects created after extensive midfoot resection in six consecutive patients with a primary malignant tumor. In all but one patient, the extent of the resection involved at least two metatarsals. The mean age (and standard deviation) at the time of the operation was 30+/-13 years. At the final follow-up examination, clinical and radiographic evaluations were performed on all patients, and functional outcome and quality of life were assessed with use of the Musculoskeletal Tumor Society score, the American Orthopaedic Foot and Ankle Society Score, and the Toronto Extremity Salvage Score. RESULTS: The median duration of follow-up was 52.2 months. Limb salvage was achieved in five patients. In the remaining patient, amputation was necessary because of flap failure. Revision surgery was necessary in all patients because of complications (skin ulcerations in three patients; hematoma in two patients; and infection, necrosis of the second toe, and flap necrosis in one patient each). At the time of final follow-up, five patients had satisfactory function and reported good quality of life. The average Musculoskeletal Tumor Society, American Orthopaedic Foot and Ankle Society, and Toronto Extremity Salvage scores were 82%, 75 points, and 92%, respectively. At the time of the final follow-up, five patients had no evidence of disease and one patient had disease. CONCLUSIONS: Following the resection of a malignant tumor in the midfoot, the use of microvascularized osteomyocutaneous fibular grafts has proven to be a successful surgical technique, offering an alternative to ablative surgery with functional restoration of the salvaged limb.     

Free vascularized fibular grafts for reconstruction of skeletal defects

Nourished by the peroneal vessels, the versatile free vascularized fibular graft can be transferred to reconstruct skeletal defects of the extremities. It may be combined with skin, fascia, muscle, and growth-plate tissue to address the needs of the recipient site. It may be cut transversely and folded to reconstruct the length and width of tibial or femoral defects. The main indications for this graft are defects larger than 5 to 6 cm or with poor vascularity of the surrounding soft tissues. Detailed preoperative planning, experience in microvascular techniques, and careful postoperative follow-up are necessary to minimize complications and improve outcome. The free vascularized fibular graft has been successfully applied as a reconstruction option in patients with traumatic or septic skeletal defect, after tumor resection, and has shown promise in patients with congenital pseudarthrosis.     

The free vascularized fibular graft for bridging large skeletal defects of the upper extremity

Large skeletal defects of the upper extremity pose a serious clinical problem with potentially deleterious effects on both function and viability of the limb. Recent advances in the microsurgical techniques involved in free vascularized bone transfers for complex limb injuries have dramatically improved limb salvage and musculoskeletal reconstruction. This study evaluates the clinical and radiographic results of 18 patients who underwent reconstruction of large defects of the long bones of the upper extremity with free vascularized fibular bone grafts. Mean patient age was 27 years (7-43 years) and mean follow-up was 4 years (1-10 years). The results confirm the value of vascularized fibular grafts for bridging large bone defects in the upper extremity.     

Primary malignant bone tumors of the shoulder girdle: surgical technique of resection and reconstruction

Limb ablation for tumors of the shoulder is a devastating procedure. Recent advances in preoperative investigative measures, adjuvant chemotherapy, and reconstructive techniques have resulted in an increased interest in limb-sparing resection. For limb-sparing procedures to present a viable alternative in these cases, recurrence rates must be comparable to those obtained with ablative surgery. In addition, the resection must result in an improvement over the status obtainable with prosthetic devices. Twenty-four patients underwent limb-salvage procedures of various forms for primary bone tumors of the shoulder girdle. At follow-up (average: 33 months), 19 patients were alive without disease, one was alive with disease, and four were dead. One patient had local recurrence. All surviving patients enjoyed nearly normal function of the distal extremity. Improvements in techniques of soft tissue reconstruction in an effort to gain function and stability after wide resection of these tumors are necessary. Results indicate that these limb-salvage attempts offer successful alternatives to mutilating and crippling proximal amputations of the upper extremity.

目的报道应用携带监测皮岛的腓骨移植修复股骨上段骨肿瘤术后骨缺损的临床效果。方法对于7例股骨上段肿瘤切除术后的骨缺损采用携带监测皮岛的腓骨进行移植。根据骨缺损长度,设计带监测皮岛(3cm×5cm)的腓骨,切除腓骨长度比骨缺损长度多4cm,上下各2cm插入股骨髓腔后用滑动鹅头钢板(DHS)桥接固定腓骨。结果全部病例获得随访12—24个月,无复发。术后功能恢复良好,腓骨和受区骨均呈骨性愈合。结论采用带监测皮岛的腓骨移植复合DHS固定是治疗股骨上段骨肿瘤术后骨缺损的有效方法。     

Microsurgical fibular flap for pelvic ring reconstruction after periacetabular tumor resection

Reconstruction after resection of tumor about the acetabulum represents a considerable challenge in reconstructive surgery. Between 1999 and 2003, three patients with periacetabular tumors underwent tumor resections (Ennecking type B) and pelvic ring reconstruction with microsurgical fibular flaps. Histological diagnosis showed osteosarcoma, giant cell tumor, and aneurysmoid bone cyst. All patients survived surgery without complications. The follow-up for patients ranged from 14 to 42 months. The average time for bone healing and full weight bearing was 13.6 weeks after surgery. In evaluations of the functional outcome using Enneking scoring system, two reached the score of excellent (>or= 23 points), and one reached the score of good (15 to 22 points). This report shows our experience in use of microsurgical fibular flaps for arthrodesis of the hip after periacetabular tumor resection, which restores the continuity of the pelvic ring with minimal shortening of the limb.

The purpose of this study was to evaluate the results of using free vascularized fibular graft (FVFG) combined with locking plate in the treatment of large skeletal defects from open fracture and infection.     

Intercalary reconstruction following resection of diaphyseal bone tumors: A systematic review

IntroductionThe options for the reconstruction of diaphyseal defects following the resection of bone tumors include biological or prosthetic implants. The purpose of our study was to evaluate different types of intercalary reconstruction techniques, including massive bone allograft, extracorporeal devitalized autograft, vascularized free fibula, and modular prosthesis.MethodsWe performed a systematic review of articles using the terms diaphyseal bone tumor and intercalary reconstruction. All the studies reporting the non-oncological complications such as infection, nonunion and fracture of the intercalary reconstructions were included. We excluded articles published before 2000 or did not involve humans in the study. Case reports, reviews, technique notes and opinion articles were also excluded based on the abstracts. Thirty-three articles included in this review were then studied to evaluate failure rates, complications and functional outcome of different surgical intercalary reconstruction techniques.ResultsNonunion rates of allograft ranged 6%–43%, while aseptic loosening rates of modular prosthesis ranged 0%–33%. Nonunion rates of allograft alone and allograft with a vascularized fibula graft ranged 6%–43% and 0%–33%, respectively. Fracture rates of allograft alone and allograft with a vascularized fibula graft ranged 7%–45% and 0%–44%, respectively. Infection rates of allograft alone and allograft with a vascularized fibula graft ranged 0%–28% and 0%–17%, respectively. All of the allograft (range: 67%–92%), extracorporeal devitalized autograft including irradiation (87%), autoclaving (70%), pasteurization (88%), low-heat (90%) or freezing with liquid nitrogen (90%), and modular prosthesis (range: 77%–93%) had similar Musculoskeletal Tumor Society functional scores. Addition of a vascularized fibula graft to allograft did not affect functional outcome [allograft with a vascularized fibula graft (range: 86%–94%) vs. allograft alone (range: 67%–92%)].ConclusionAseptic loosening rates of modular prosthesis seem to be less than nonunion rates of allograft. Adding a vascularized fibula graft to allograft seems to increase bone union rate and reduce the risk of fractures and infections, though a vascularized fibula graft needs longer surgical time and has the disadvantage of donor site morbidity. These various intercalary reconstruction techniques with or without a vascularized fibula autograft had similar functional outcome.     

Treatment of large skeletal defects in the lower extremities using double-strut, free vascularized fibular bone grafting.

This article reports on the use of double-strut, free vascularized fibular grafts to treat six patients with infected nonunion or traumatic bone loss in the femur or tibia after prolonged treatment and multiple operations. The defects were 6-13 cm long. Five patients achieved solid union within 6 months, and one patient required additional cancellous grafting to achieve union at the distal end of the fibula. One patient experienced a stress fracture due to strenuous exercise, and union was achieved 3 months after reapplying an external fixator. Although three patients had some restricted knee motion, all patients had a satisfactory outcome in regard to walking, and no limb-length discrepancies were noted in any patient.
