Aims:Vascularized fibula has been widely used in limb salvage surgery to reconstruct large bone defects. Aim of this study is the analysis of the complications related both to the donor and the recipient site in a series of patients affected by bone tumors. Material and methods: In the period from 1988 to 2002, 114 patients ranging in age between 4 and 64 years underwent bone reconstruction by mean of a vascularized fibula graft. There were 64 men and 50 women and all them were affected by malignant neoplasm. The upper limb was involved in 25 cases and the lower extremity in 89 cases. The length of resection ranged between 7 and 28 cm, the follow up between 6 and 166 months. Results: Several complications have been noted either at the donor or at the recipient site. The most common complications affecting the donor leg, have been the retraction of flexor tendons (6), the valgus deformity of the ankle (3) the retraction of extensor hallucis longus (1) and a transient palsy of the peroneal nerve (1). The most frequent complications observed at the recipient site has been a fracture of the graft (15) followed by non union (12), infection (5 cases), failure of plate (5), skin necrosis (4), transient palsy of the peroneal nerve (3) and joint stiffness. Because of complications, a total failure of the procedure occurred in 4 cases. Conclusions: Although the vascularized fibula graft is the recommended procedure in dealing with challenging reconstruction of large diaphyseal defects, this option is not free of complications. However, in our experience, when conservative treatment of complications was not successful, further surgery was able to lead to recovery in the majority of cases

Introduction

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.

Introduction

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.

Objective and Purpose: Pilon fractures are complex fractures of the tibial articular surface usually associated with high energy trauma and major soft tissue injury. We investigated the effectiveness of Ilizarov external fixator in such cases. At our hospital, we obtain excellent results performing reconstruction using vascularised fibular grafts for the infectious non-union.

Methods and Materials: We examined 21 cases treated with the Ilizarov apparatus for the fresh pilon fracture from 1999. There were 13 males and 8 females, with an average of 44 years. The AO classification was A2 type in 2 cases, B1 in 4, C1 in 3, C2 in 3, and C3 in 9, with open fractures of Gustilo type?Uor ?Va in 7 cases. 11 cases were treated by the Ilizarov technique only. 10 cases were treated by the additional limited open reduction with screw, K-wire and fibular plating. The average time between injury and surgery was 4 days. We examined 6 cases treated with the vascularised fibular graft for the infectious non-union cases after internal fixation. Age at the surgery was from 19 to 70 (mean 46).

Results: All fractures were united and removed at an average of 10 weeks (range 8–12 weeks). Complications included 5 cases of superficial pin tract infections. There is no deep infections and no pseudarthrosies.

Conclusion: The use of Ilizarov fixator is a safer method of treatment of pilon fractures, especially for the severe soft tissue injury and we don ft delay surgery for soft tissue considerations.

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.

Aims

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.

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. Vascularized fibula grafting remains a valuable option in limb salvage surgery with acceptable long-term outcomes. However, especially in lower extremity cases, a low rate of graft union and multiple reoperations are to be expected

Aim. Vascularized fibula flap is one of the available options in the management of bone loss that can follow cases of severe haematogenous osteomyelitis. The aim of this study was to evaluate the outcomes of this procedure in a pediatric population in a Sub-saharan setting. Method. The retrospective study focuses on the procedures done in the period between October 2013 and December 2016. Twenty-eight patients, 18 males and 10 females, were enrolled. The youngest was 2 years old, the oldest 13. The bones involved were tibia (13), femur (7), radius (5) and humerus (3). In 5 cases the fibula was harvested with its proximal epiphysis, whereas in 17 cases the flap was osteocutaneous and osseous in 6 cases. In most cases, operations for eradication of the infection were carried out prior to the graft. The flap was stabilized mainly with external fixators, rarely with Kirschner's wires or mini plate. No graft augmentation was used. Results. Graft integration was achieved in 24 cases. Three cases of early flap failure required the removal, while in one case complete reabsorption of the flap was noted a few months after the procedure. The follow-up period ranged from a minimum of 2 and half to a maximum of 6 years. Integration of the graft was obtained in a period of 4 months on average. The fibular flap with epiphysis had good functional outcomes with reconstruction of articular end. Early and delayed complications were observed. All grafts underwent a process of remarkable remodeling. No major problems were observed in the donor site, except for a transitory foot drop that resolved spontaneously. Conclusions. Reconstruction of segmental bone defects secondary to hematogenous osteomyelitis with vascularized fibula flap is a viable option that salvages and restores limb function. It can be safely used even in early childhood. The fibula can be harvested as required by the local conditions. When harvested with a skin island, bone loss and poor soft tissues envelope may be addressed concurrently. The procedure is long and difficult but rewarding. When surgical skills and facilities are available, it can be carried out even in settings located in low resources countries

Aims

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.

Aims

We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts
