Live fibular Graft for the Treatment of Long Bone Tumors in Children

引用

Journal of Cancer Therapy 2017年第3期8卷 225-233页

作者： Seung-Koo Rhee Mohammed Einayet Abdelhameed Chi-Hoon Ahn Cheol-U Kim Department of Orthopaedic Surgery Bone & Joint Tumor Division Daejeon Sun Medical Center Daejeon Korea Department of Orthopaedic Surgery Sharg Alneel Hospital Khartom Sudan

Purposes: We would like to inform the characteristics of recurred osteo-fibrous dysplasia (OFD), and also the possible use of vascularized composite autograft and allografts (VCA) combined with live fibular graft (LFG) for the treatment of aggressive benign bone tumor and osteogenic sarcomas in children. Materials and Methods: We reviewed one boy with recurred OFD after LFG, and other four children with osteogenic sarcoma in long bone which was treated with LFG and VCA, and followed them for average 9 years (3 - 14 years). Survival of the LFG and VCA was estimated by the ISOLS Functional Radiologic Scoring System, but not with Kaplans-Meier’s scoring system because of a small series of case reports. Results: All succeed after surgeries initially, but the cause of recurrence of OFD was still unclear, and one girl with osteogenic sarcoma on distal femur died with skip and lung metastasis, 4 years after surgeries. Conclusions: The causes of recurred OFD are not found thru pathologic studies of our patient, but we believe the multifocal origin of tumor cells even on the adjacent soft tissues in OFD is one of the causes. The excised long bone tumor is recycled by pasteurization or autoclaving, or allograft, then LFG, and neo-adjuvant chemotherapy would be one of elective surgery for the treatment of malignant long bone tumors in children. The LFG into recycled autograft or allograft bone is difficult to perform simultaneously, but very effective to increase more earlier regenerative vascularities and also the stabilities of the dead bones in children.

Three-Dimensional Finite Elemental Analysis of Bone Stress near an Implant Placed at the Border between Mandible and fibular Graft in Mandibular Reconstruction

引用

Open Journal of Regenerative Medicine 2015年第4期4卷 35-45页

作者： Yukawa Ken Tachikawa Noriko Kasugai Shohei Oral Implantology and Regenerative Dental Medicine Department of Masticatory Function Rehabilitation Tokyo Medical and Dental University Tokyo Japan

Purpose: The aim of the present study was to use finite elemental analysis (FEA) to evaluate bone stress near an implant placed at the border between the mandible and fibular graft in mandibular reconstruction. Materials and Methods: A fibular model (FM) and transplantation model (TM) were constructed for FEA. In TM, mandible was on the mesial side and the fibular graft was on the distal side. The implant was positioned at the center of both bone models. In TM, it was placed on the border between the mandible and fibular graft. A 10-mm implant was used in the monocortical model and a 15-mm implant was used in the bicortical model. The loading force was set at 100 N, the angle was set at 90°, and the loading position was set as center, mesial, or distal on the upper surface of the prosthesis. Von Mises equivalent stress values of the bone near the implant collar and apex at the middle line between buccal and lingual side were measured. Results: In all models, stress values were significantly lower with center loading than with distal loading and mesial loading. In center loading, the stress values were significantly lower in the bicortical model than in the monocortical model. There were no significant differences in stress values between FM and TM in all conditions. Conclusions: Bone stress was least with the center loading position, which was further decreased by bicortical fixation. There was no increase in mechanical stress associated with placing an implant at the border between the mandible and the fibular graft.

Three-Dimensional Computed Tomography Assessment and Planning for Severe Lower Limb Deformities: A Case Report of Bilateral fibular Hemimelia

引用

Open Journal of Orthopedics 2013年第3期3卷 167-171页

作者： Yoshiteru Kawasaki Mitsuhiko Takahashi Natsuo Yasui Department of Orthopedics Institute of Health Biosciences The University of Tokushima Graduate School Tokushima Japan.

To correct a lower limb deformity, orthopedic surgeons must have an exact understanding of the deformity. In general, preoperative planning is carried out using anterior-posterior (AP) and lateral radiographs. However, for severe cases with a combination of angular and rotational deformities of the lower limb, obtaining true AP and lateral radiographs is difficult and accurate calculation of the rotational deformity from radiographs is impossible. In this report, we propose to focus on preoperative assessment using three-dimensional (3D) reconstruction images of computed tomography (CT) scans for severe lower limb deformity in a patient with bilateral fibular hemimelia type II according to the Achterman- Kalamchi classification. She underwent bifocal deformity corrections of the bilateral tibiae using Taylor spatial frames in combination with the Ilizarov external fixator. Complete bony union was achieved, without angular deformity or limb length discrepancy.

Open Journal of Orthopedics 2014年第11期4卷 285-291页

作者： Venkatesh Gupta Vijaya Kumar Department of Orthopaedics Mamata Medical College Khammam India

Giant cell tumour of the distal radius is the 3rd most common site after proximal tibia and distal femur. It is locally aggressive and is associated with a high rate of recurrence. Although it is usually treated with various modalities of treatment, wide resection and reconstruction with proximal fibular autograft is most commonly accepted in recurrent cases. The following is a case report of such a case with surgical management.

Reconstruction Using a Free Vascularized fibular Graft after Frozen Autograft Reconstruction for Osteosarcoma of the Distal Tibia: A Case Report

引用

Modern Plastic Surgery 2013年第1期3卷 47-50页

Recently we have been performing biological reconstruction for malignant bone tumors of the extremities using frozen autografts. Here we present a case treated with free vascularized fibular graft (FVFG) after this method. A 23-year-old man developed osteosarcoma in his left distal tibia. There was nonunion after frozen autograft reconstruction, which we treated with FVFG. Twenty-four months later, bridging between the host bone and the frozen autograft was achieved. Our department has achieved bone union in almost all cases, but we sometimes encounter cases of nonunion after this method because of delayed blood supply. In these instances, reconstruction using FVFG may represent an attractive choice for salvage treatment.

Giant cell tumor(GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome.

Long-Term Follow-Up of Microsurgical Reconstruction for Pelvic Tumor Focusing on Spinal Deformity and Quality of Life

引用

Journal of Cancer Therapy 2014年第4期5卷 354-362页

作者： Soichi Ejiri Shin-ichi Kikuchi Takahiro Tajino Ryoichi Kawakami Michiyuki Hakozaki Shin-ichi Konno Department of Orthopaedic Surgery Fukushima Medical University School of Medicine Fukushima Japan

Background: To provide patients with a superior quality of life (QOL) after their pelvic tumor resection, ensuring the stability of the trunk as well as satisfactory lower extremity function is important. Although microsurgical reconstructions for the pelvic ring and hip are used clinically, the details of postoperative long-term spinal deformity and QOL remain unclear. Methods: The patients were 66- and 43-year-old men and a 43-year-old woman. The mean postoperative follow-up period was 134 months. The surgical procedures performed on these patients were: pelvic ring reconstruction using a double-barreled free vascularized fibular graft (FVFG) in Patient 1;simultaneous pelvic ring reconstruction using FVFG and hip arthrodesis in Patient 2;and latissimus dorsi free flap without pelvic ring reconstruction in Patient 3. As indicators of spinal deformity, we measured the Cobb angle, thoracic kyphosis angle, lumbar lordosis angle, pelvic angle on the sagittal plane, and sagittal plane balance using whole spine radiography. To assess the patients’ QOL, we examined the International Society of Limb Salvage (ISOLS) score, the Roland-Morris Disability Questionnaire (RDQ), activities of daily living (ADL) satisfaction using a visual analogue scale (VAS), and the SF-36. Results: Spinal alignment in the frontal plane worsened in order from Patient 1 to 3. Spinal alignment and pelvic tilt in the sagittal plane were at appropriate levels in Patients 1 and 2. The trunk tilt in the sagittal plane was at an appropriate level only in Patient 1. In the QOL assessment, the function of the affected limb worsened in order from Patient 1 to 3. RDQ scores were lower than the national norm in Patients 2 and 3. With respect to ADL satisfaction and the SF-36, Patient 3 had a markedly low VAS, physical functioning, role-physical, and role-emotional scores. Conclusion: In the long-term clinical course after pelvic tumor resection, in order to obtain satisfactory spinal alignment and QOL, pelvi
