Oral and masticatory rehabilitation using osseointegrated dental implants after resective treatment of multicystic ameloblastoma in the lower jaw with a fibula graft

Ameloblastoma is an aggressive odontogenic tumor which typically occurs between third and fourth decade of life that often needs resective approach. Immediate reconstruction may show better results. The treatment of multicystic ameloblastoma in the mandible being a rare case that occurred in the late second decade of life, which was surgically removed along with the affected teeth with safety margins, and the region was immediately reconstructed using a vascularized graft, removed from the fibula. Its integration, in combination with osseointegrated dental implants and fixed implant-supported prostheses, restored chewing function and esthetics. After 6 years from fibular graft and 24 months of dental implants, an excellent outcome was observed, with oral health and normal functions properly restored, and the immediate reconstruction of the mandible in resective cases, associated with oral rehabilitation with dental implants, may be considered a suitable treatment option.

Osteotomía proximal en cuña abierta de tibia con injerto de peroné en la enfermedad de Blount / Ostéotomie tibiale proximale en chevron ouvert et greffon de péroné dans la maladie de Blount / Proximal osteotomy in tibia open wedge with fibular graft in Blount's disease

Introducción: La tibia vara es una enfermedad compleja que consta de varias deformidades en la rodilla y la pierna. Su tratamiento es controvertido. Con las técnicas quirúrgicas actuales se logra la corrección, pero la tendencia a la recidiva es elevada. Objetivo: Evaluar el uso de la osteotomía proximal de tibia en cuña abierta con injerto de peroné en la enfermedad de Blount. Métodos: Se realizó un estudio de intervención en 11 pacientes (18 miembros inferiores) con tibia vara, con edades entre 3 y 18 años, que acudieron a la consulta externa del Servicio de Miembro Inferior y Artroscopia del Complejo Científico Ortopédico Internacional Frank País del 1ro de junio de 2009 al 31 de mayo de 2011. A estos pacientes se les realizó una osteotomía proximal en cuña abierta medial de tibia. Se empleó un injerto estructural de peroné para corregir la deformidad. Se utilizaron los criterios clínico-radiográficos de Schoenecker PL y otros para la evaluación del procedimiento quirúrgico. Resultados: A partir de la propuesta de Schoenecker PL y otros, se pudo comprobar que 77,77 por ciento de los resultados fueron buenos; 16,66 por ciento, regulares, y 11,11 por ciento, malos, lo cual demuestra que el tratamiento con esta técnica fue efectivo. Se determinó además que un ángulo tibiofemoral mayor de 30º y un estadío radiográfico avanzado de la enfermedad son factores que afectan negativamente los resultados obtenidos. Conclusión: La osteotomía proximal en cuña abierta medial de tibia con injerto estructural de peroné ofreció buenos resultados clínicos y radiográficos en el tratamiento de la enfermedad de Blount(AU)

Introduction: Tibia vara is a complex disease consisting in several deformities in the knee and leg. The treatment is controversial. Correction is achieved with current surgical techniques, but the tendency to relapse is high. Objective: To evaluate the use of medial opening wedge proximal tibial osteotomy with fibular graft in Blount's disease. Methods: An intervention study was achieved in 11 patients (18 lower limbs) with tibia vara. The ages of these patients ranged from 3 to 18 years, and they were assisted in the outpatient clinic of the Lower Limbs and Arthroscopy Service at Frank País International Orthopedic Scientific Complex from June 1, 2009 to May 31, 2011. These patients underwent medial opening wedge proximal tibial osteotomy. A fibular structural graft was used to correct the deformity. The clinical and radiographic criteria of Schoenecker PL and others were used for the evaluation of the surgical procedure. Results: As of the proposal of Schoenecker PL and others, it was found that 77.77 percent of the results were good; 16.66 percent acceptable, and 11.11 percent poor, which shows this technique was effective for the treatment. It was also determined that a tibiofemoral angle larger than 30º and an advanced radiographic stage of the disease are factors that negatively affect the results. Conclusion: The medial opening wedge proximal tibial osteotomy with structural graft offered good clinical and radiographic results in the treatment of Blount's disease(AU)

Introduction: Le tibia vara est une maladie complexe comportant plusieurs déformations au niveau du genou et de la jambe. Son traitement est controversé. Elle peut être corrigée par les nouvelles techniques chirurgicales, mais la récidive tend à être élevée. Objectif: Évaluer l'utilisation de l'ostéotomie tibiale proximale en chevron ouvert et du greffon de péroné dans la maladie de Blount. Méthodes: Une étude interventionnelle de 11 patients (18 extrémités inférieures), âgés de 3 à 18 ans, atteints de tibia vara, et vus en consultation externe du 1 janvier 2009 au 31 mai 2011 au service des affections des extrémités inférieures et d'arthroscopie du Complexe scientifique internationale d'orthopédie «Frank Pais¼, a été réalisée. Ces patients ont été traités par une ostéotomie tibiale proximale en chevron ouvert médial. Un greffon structurel de péroné a été employé pour corriger la déformation. On a utilisé les critères cliniques et radiographiques de Schoenecker PL et al pour évaluer la procédure chirurgicale. Résultats: À partir de la proposition de Schoenecker PL et al, on a pu constater que les résultats ont été bons (77.77 pourcent); acceptables (16.66 %), et mauvais (11.11 pourcent), montrant ainsi que la technique était effective. On a aussi trouvé qu'une angulation tibio-fémorale de plus de 30° et un stade radiographique avancé de la maladie sont des facteurs influant négativement sur les résultats obtenus. Conclusions: L'ostéotomie tibiale proximale en chevron ouvert médial et le greffon structurel de péroné offrent de bons résultats cliniques et radiographiques dans le traitement de la maladie de Blount(AU)

Clinical comparison of vascularized fibular flap transplantation with vancomycin calcium sulfate in treatment of chronic osteomyelitis and bone defects / 实用医学杂志

Objective To compare the clinical effect of vascularized fibular flap transplantation and vancomycin sulfate calcium on chronic osteomyelitis of the tibia and bone defects.Methods A total of 35 cases with chronic tibial osteomyelitis and bone defect were involved and divided into group A with 21 cases receiving anastomosis of vascularized fibular flap transplantation and group B with 14 cases recciving vancomycin sulfate calcium.Infection control rate and Enneking score were compared in both groups.Simultaneous detection of two groups preoperative,postoperative 2 weeks,1 month and 3 months of the levels of CRP and PCT were conducted.Results Postoperative CRP and PCT were under control in both groups.No statistical significance was found in the comparison of CRP and PCT preoperative and postoperative 2 weeks,1 month and 3 months.In terms of infection control rate,two groups had no signiticant difference (P ＞ 0.05) and there was statistical significance of the comparison of postoperative Enneking score (P ＜ 0.05).Conclusions The clinical results of the two methods are satisfied.The infection degree and the length of the bone defect are decisive factors in choosing the treatment method and sometimes the combination of two treatment methods may be a better choice.

Reconstruction of Large Femur and Tibia Defect with Free Vascularized Fibula Graft and Locking Plate

PURPOSE: The reconstruction of femur and tibia defects following tumor resection remains a surgical challenge. The clinical outcome of free vascularized fibula graft (VFG) reconstruction with locking plate for massive femur and tibia defects of more than 10 cm that were secondary to skeletal tumor resection is reported. MATERIALS AND METHODS: Thirteen patients with a mean follow-up of 3.3 years were reviewed. Seven patients received vascularized fibula grafts in the femur and six in the tibia. The mean bony defect of the femur and tibia was more than 10 cm and the length of the grafted fibula was more than 15 cm. All defects were stabilized with long locking plates. RESULTS: All patients were free of disease at final follow-up; All VFGs were transferred successfully. All patients had a successful outcome with bony union. Stress fractures of the grafted fibula had occurred but the locking plate stabilized the fracture and healed until the last follow-up. All patients were able to walk without a brace after a mean of 9 months postoperatively. CONCLUSIONS: VFG with locking plate is a reliable reconstructive procedure for massive femur and tibia defects.

Large desmoplastic fibroma: case report using microvascularized fibula graft for reconstruction / Fibroma desmoplásico de grandes proporções: relato de caso usando enxerto microvascularizado de fibula para reconstrução

The Desmoplastic Fibroma is a benign rare tumor of fibroblastic origin, representing only 0.03% of benign bone tumors. Displays aggressive behavior and high rates of recurrence, which makes the treatment more aggressive. The authors present a case of an 11 years-old female, complaining of increased volume in the jaw. The patient had an extensive swelling of the left mandibular body with invasion of the border of the tongue and floor of the mouth at the same side. She had a history of 4 recurrences at the same site. Image exams revealed expansive lesion in body and ramus of the mandible with involvement of soft tissue on the lingual side of the lesion. The treatment was excision of the lesion with extra oral access and reconstruction with microvascularized fibula graft. The patient has been followed for 2 years with no clinical or radiographic signs and without recurrence

O Fibroma Desmoplásico é um tumor benigno raro de origem fibroblástica que representa apenas 0,03% dos tumores ósseos benignos. Apresenta comportamento agressivo e elevadas taxas de recorrência, o que torna o seu tratamento mais agressivo. Os autores apresentam um relato de caso de uma paciente do sexo feminino de 11 anos de idade com queixa de aumento de volume em mandíbula. A mesma apresentou extensa expansão do corpo mandibular esquerdo, com invasão da borda da língua e assoalho da boca do mesmo lado, com histórico de quatro recorrências na mesma localização. Os exames de imagem revelaram lesão expansiva no corpo e ramo da mandíbula com envolvimento dos tecidos moles do lado lingual da lesão. O tratamento foi a excisão da lesão com acesso extra-oral e reconstrução com enxerto microvascularizado de fíbula. A paciente apresenta seguimento de 2 anos sem sinais clínicos ou radiográficos de recidiva.

Free fibula and flap graft for reconstruction all the first metatarsal bone / 中华显微外科杂志

Objective To evaluate the clinical effects of free fibula and flap grafts on the repair of all the first metatarsal bone at one stage.Methods There were 9 cases with the first metatarsal bone defect from Janurary 2003 to December 2009 that treated with free vascularized fibular bone and free vascularized flap at one stage.In which 6 cases reconstructed at the primary stage and 3 cases reconstructed at the second stage.Seven cases reconstructed by free vascularized fibular combined with ALTPF,two cases reconstructed by free vascularized fibular combined with TAPF.The free vascularized fibular and flap restored the first metatarsal bone and the soft tissue defects respectively.Vascular anastomosis was the artery of flap anastomosis with anterior tibial artery and the vein of the flap anastomosis with great saphenous vein,the peroneal artery and accompany vein anastomosis with artery and vein of the flap.Results The grafted tissues survived smoothly in 8 cases,vein crisis happened in I case and the ALTPF necrosis after blood vessels expedition.So the TAPF was changed to cover the soft defect and survived smoothly.Followiy-up were done from 6 to 36 months in 9 cases.There were no ulcer on flaps and no fracture again,the fibulas had been bone healing.Evaluated by Maryland standards,six cases were excellent,two cases were fine,one case was good.Conclusion The fibula combined flap grafts provide a relatively better alternative to repair the first metatarsal bone compound tissue defects at one stage.In addition,the procedure decreased frequency of operations and short the course of treatment.Sensory function reconstruction of fibula flaps should be given full attention.As fine function of the reconstructed foot,it is a effective method for reconstruction the burdened area of the foot.

Free Vascularized Fibular Grafts for Treatment of Infected Nonunion of the Tibia

PURPOSE: To analyze the result of free vascularized fibular grafting for treatment of infected nonunion of the tibia with radical bone and soft tissue defect. MATERIALS AND METHODS: 17 patients with infected nonunion of the tibia who underwent a reconstruction using free vascularized fibular grafting were reviewed retrospectively. The mean follow-up period was 70.3 months. We analyzed the results radiographically which included the time of bone union, the amount of hypertrophy of grafted bone and complications. RESULTS: The average length of bone defect was 8.8 cm (5~15 cm), and the average length of fibular graft was 14.1 cm (10~17.5 cm). Bony union was achieved in 11 of 17 cases and the average time of bone union was 5.2 months (4~6 months). There were 6 cases of nonunion. All nonunions developed at the proximal end of graft in patients who underwent fixation using pin and external fixator. Union was eventually achieved in all cases in 6.0 months (5~8 months) after the cancellous bone graft and plate internal fixation. Hypertrophy of grafted bones with more than 20% developed only in 4 cases out of 17. There were 3 cases of stress fracture, however there was no recurrence of infection or serious donor site morbidity. CONCLUSION: Free vascularized fibula grafting is one of the most effective reconstruction options for the infected nonunion of the tibia with radical bone and soft tissue defect. Strong internal fixation using plate and screws is required to reduce the rate of nonunion and stress fracture of grafted fibulas.
