Introduction. Vascularized fibular grafting following tumor resection is an essential treatment option in limb salvage surgery. This study aimed to assess the surgical and oncological outcomes of patients treated in Denmark between 2010 and 2022. Method. We present a retrospective review of a national cohort comprising 27 patients. The indications were 13 cases of Ewing sarcoma, 12 cases of osteosarcoma, and 2 cases of giant cell tumor. The median age at surgery was 16 years (range: 2-39), and the median follow-up was 82 months (range: 12-138). Patients were analyzed overall and stratified into upper and lower extremity groups based on tumor location. Result. The primary rate of graft union was 63%, and after secondary procedures, the overall rate of graft union was 67%, with a median time to union of 13 months (range: 7-29). The reoperation rate was 74%, while the rate of limb salvage was 93%, with two patients undergoing amputation during follow-up. The 5-year overall survival rate was 81% (95% CI: 61-92). Patients with upper extremity tumors were more likely to attain graft union (92% vs. 47%, p=0.02) and less likely to undergo multiple reoperations (17% vs 60%, p=0.047) compared to patients with lower extremity tumors. Conclusion.
The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration. Sixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents.Introduction
Materials & Methods
The use of vascularised fibula grafts is an accepted method for reconstructing the distal femur following resection of malignant childhood tumours. Limitations relate to the mismatch of the cross-sectional area of the transplanted fibula graft and thel ocal bone, instability of the construct and union difficulties. We present midterm results of a unique staged technique—an immediate defect reconstruction using a double-barrel vascularised fibula graft set in in A-frame configuration and a subsequent intramedullary femoral lengthening. We retrospectively included 10 patients (mean age 10 y)with an osteosarcoma of the distal femur, who were treated ac-cording to the above-mentioned surgical technique. All patients were evaluated with regards to consolidation of the transplanted grafts, hypertrophy at the graft-host junctions, leg length discrepancies, lengthening indices, complications as well as functional outcome.Introduction
Materials & Methods
We have previously reported cryoablation-assisted joint-sparing surgery for osteosarcoma with epiphyseal involvement. However, it is not clear whether this is a comparable alternative to conventional joint arthroplasty in terms of oncological and functional outcomes. A total of 22 patients who had localized osteosarcoma with epiphyseal involvement around the knee and underwent limb salvage surgery were allocated to joint preservation (JP) group and joint arthroplasty (JA) group. Subjects were followed with radiographs, Musculoskeletal Tumor Society (MSTS) score, and clinical evaluations at one, three, and five years postoperatively.Aims
Methods
The use of frozen tumour-bearing autograft combined with a vascularized fibular graft (VFG) represents a new technique for biological reconstruction of massive bone defect. We have compared the clinical outcomes between this technique and Capanna reconstruction. From June 2011 to January 2016 a retrospective study was carried out of patients with primary osteosarcoma of lower limbs who underwent combined biological intercalary reconstruction. Patients were categorized into two groups based on the reconstructive technique: frozen tumour-bearing autograft combined with concurrent VFG (Group 1) and the Capanna method (Group 2). Demographics, operating procedures, oncological outcomes, graft union, limb function, and postoperative complications were compared.Aims

Aim.
We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts This retrospective study included 27 patients who underwent resection en bloc and reimplantation of an extracorporeal irradiated autograft. The mean patient age and follow-up period were 31.7 years (9 to 59) and 16.6 years (10.3 to 24.3), respectively. The most common diagnosis was osteosarcoma (n = 10), followed by chondrosarcoma (n = 6). The femur (n = 13) was the most frequently involved site, followed by the tibia (n = 7). There were inlay grafts in five patients, intercalary grafts in 15 patients, and osteoarticular grafts in seven patients. Functional outcome was evaluated with the Musculoskeletal Tumor Society (MSTS) scoring system.Aims
Patients and Methods
Following resection of primary malignant bone tumours of the humerus, limb salvage can be performed by vascularized fibula graft for reconstruction of large segmental defects. In 12 patients with malignant bone tumour of the proximal humerus, tumour was resected and the bone defect reconstructed by vascularized fibula graft. Median age of the patients was 23 years. Median follow up was 114 months. In 10 patients humeral head had to be resected and was replaced by fibular transplant including head and shaft of the ipsilateral fibula. Humeral head could be left in place in 2 patients. Median length of transplant was 17.2 cm. Radiographic union could be seen after 8 months in median. In 7 patients partial necrosis of the fibular head occurred, in 4 patients fracture of the transplant happened following trauma. In these 4 cases revision surgery was required. Partial necrosis of the head of fibula had no significant influence on shoulder function. One patient died of disease, the others are disease free. Enneking Index was 61% in median at time of last follow up. At donor side 3 cases of transient peroneal palsy could be seen. We conclude that vascularized fibula graft is a successful surgical procedure for upper limb salvage especially for preservation of joint function also in long term follow up.
