ABSTRACT

Introducción: El objetivo de este estudio es reportar los resultados funcionales, el retorno al deporte, la tasa de consolidación y las complicaciones en deportistas jóvenes con una cirugía de Latarjet previa fallida, tratados con injerto autólogo de cresta ilíaca.Materiales y métodos: entre el 2017 y el 2020, se operaron en nuestra institución doce pacientes con inestabilidad glenohumeral recurrente luego de una estabilización previa fallida con cirugía de Latarjet, con injerto autólogo de cresta ilíaca como cirugía de revisión. La evaluación funcional se realizó con el score de Rowe, la escala visual análoga (EVA) y el score de ASOSS. Evaluamos el porcentaje de retorno al deporte, el nivel alcanzado y el tiempo que tardaron los deportistas en volver a competir. La consolidación ósea y la posición adecuada del injerto se analizó en todos los casos con radiografías de hombro frente y perfil y tomografía axial computada con reconstrucción 3D. Se registraron las complicaciones y las revisiones.Resultados: el seguimiento promedio fue de 42.6 meses (rango 24 a 92 meses). El score de Rowe, la EVA y el ASOSS mejoraron significativamente luego de la cirugía (p <0.1). Nueve pacientes retornaron al deporte, ocho de ellos al mismo nivel. El injerto óseo consolidó en todos los pacientes. No hubo recurrencias. No se reportaron complicaciones.Conclusión: el injerto autólogo de cresta ilíaca es una opción válida para el tratamiento de deportistas con inestabilidad glenohumeral recurrente luego de una estabilización previa fallida con cirugía de Latarjet. Nivel de Evidencia: IV


Introduction: The purpose of this study was to report the functional results, return to sport, consolidation rate and complications in young athletes with a previous failed Latarjet surgery, treated with an autologous iliac crest graft.Materials and methods: between 2017 and 2020, twelve patients with recurrent glenohumeral instability were operated on at our institution after previous failed stabilization with Latarjet surgery with autologous iliac crest graft as revision surgery. Functional evaluation was performed with the Rowe score, the VAS, and the ASOSS score. We evaluated the percentage of return to sport, the level reached, and the time it took the athletes to compete again. Bone consolidation and the adequate position of the graft were evaluated in all cases with front and profile X-rays of the shoulder and computed tomography with 3D reconstruction. Complications and revisions were recorded.Results: the average follow-up was 42.6 months (range 24 to 92 months). The Rowe score, visual analog scale, and ASOSS were significantly improved after surgery (p <0.1). Nine patients returned to sport, eight of them at the same level. The bone graft consolidated in all patients. There were no recurrences. No complications were reported.Conclusion: autologous iliac crest grafting is a valid option for the treatment of athletes with recurrent glenohumeral instability after previous failed stabilization with a Latarjet procedure. Level of Evidence: IV

ABSTRACT

ABSTRACT Objective: To evaluate the donor site morbidity of iliac and fibular nonvascularized bone graft after mandibular resection. Material and Methods: This study was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in PubMed, Proquest, Science Direct, and Ebsco. A total of 12 studies met the criteria of studies in humans using iliac and fibular nonvascularized bone grafts in mandibular reconstruction after mandibular resection. Results: A greater proportion of patients received iliac nonvascularized bone graft (88.9%) than fibular nonvascularized bone graft (11.1%). Of the 385 cases of iliac bone graft, 153 cases (40%) experienced complications at the iliac donor site, whereas in 48 cases of fibular bone graft, two (4%) experienced complications at the donor site. Hemorrhage, bone fracture, infection requiring debridement, and hematoma were the major complications. Conclusion: The morbidity rate of the nonvascularized bone graft donor site of the fibula (4%) tended to be lower than that of the ilium (40%). Patient age and defect size were not significantly correlated with the occurrence of morbidity donor sites in either the ilium or fibula.

ABSTRACT

Introducción: El injerto óseo autólogo tomado de la cresta ilíaca posterior para artrodesis de columna presenta ventajas: es osteogénico, osteoinductor y osteoconductor, y sus desventajas son ofrecer una cantidad limitada y las complicaciones del sitio dador (8-39%), como dolor de la zona dadora, lesión neurovascular y fracturas de pelvis. Los objetivos de este estudio fueron comparar la toma de injerto cortico-esponjoso de cresta ilíaca posterior mediante técnica con escoplo gubia frente a la toma con cureta; evaluar las complicaciones intraoperatorias y posoperatorias; cuantificar la cantidad recolectada y graduar el dolor en la zona dadora. Materiales y Métodos: Estudio prospectivo aleatorizado de 34 pacientes consecutivos para artrodesis posterolateral de columna torácica y lumbosacra (26 mujeres y 8 hombres, de entre 15 y 79 años de edad). Se los dividió en dos grupos: grupo 1, cureta y grupo 2, escoplo gubia. Se evaluaron el peso obtenido, el tiempo requerido y las complicaciones. Resultados: Grupo 1: 19 pacientes (14 mujeres y 5 hombres). Se requirieron, en promedio, 9.94 min para obtener 9,26 g. En el primer control, 13 pacientes presentaron un valor 1; 5, un valor 2 y uno, un valor 3. En el tercer control, 15 tuvieron un puntaje 1; 2, un puntaje 2 y 2, un puntaje 3. Grupo 2: 15 pacientes (12 mujeres y 3 hombres). Se tomaron 11,26 g en 8,6 min. En puntaje de dolor en el primer control fue: 10 pacientes con un valor 1; 2, con un valor 2 y 3, con un valor 3, todos tuvieron un puntaje 1 en el tercer control. Conclusiones: La toma de injerto de cresta ilíaca posterior utilizando escoplo gubia es más rápida, recolecta más injerto y provoca menos dolor a los 60 días. Nivel de Evidencia: II


Introduction: The autologous bone graft harvested from the posterior iliac crest for spinal fusion presents osteogenic, osteoinductive and osteoconductive advantages; however, its disadvantages include a limited amount of available material and an incidence of donor site complications ranging from 8% to 39%, including donor site pain, neurovascular injury and pelvic fractures. Objectives: To compare the posterior iliac crest corticoancellous harvest using a chisel-gouge approach versus a curette approach; to evaluate intra-operative and post-operative complications; to quantify the harvested bone; to grade donor site pain. Materials and Methods: Prospective randomized study in 34 consecutive patients for posterolateral fusion of the thoracic and lumbosacral spine; 26 women and 8 men, between 15 and 79 years of age. Subjects were divided into two groups. Group 1: curette approach; and Group 2: chiselgouge approach. The evaluation included: the amount of bone harvested, the time required and complications. Results: Group 1: 19 patients, 14 women and 5 men. The procedure lasted an average of 9.94 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at the first follow-up survey: 13 patients scored 1; 5 scored 2; 1 scored 3. Denis Pain Scale scores at the third follow-up survey: 15 patients scored 1; 2 scored 2; 1 scored 3. Group 2: 15 patients, 12 women and 3 men. The procedure lasted an average of 8.6 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at their first follow-up: 10 patients scored 1; 2 scored 2; 3 scored 3. At the third follow-up, all patients scored 1. Conclusions: We observed that the posterior iliac crest graft harvested using the chisel-gouge approach is faster, provides more graft and results in less pain at 60 days. Level of Evidence: II

ABSTRACT

Objetivo: mostrar el tratamiento que realizamos en comunicaciones a nivel del reborde alveolar en los FLAP, tanto para pacientes con fisura unilateral como bilateral, realizados con cresta ilíaca tomada del paciente y basados en nuestra experiencia de más de 40 años. Casos clínicos: nuestro protocolo está dentro de lo que es el tratamiento que proponemos para FLAP, ortopédico y quirúrgico, teniendo en cuenta el crecimiento y desarrollo del maxilar superior, realizando dentro de éste lo que son las periostioplastías y los injertos óseos, con el correspondiente seguimiento de pacientes en el tiempo. Conclusión: se realiza un protocolo adecuado para cada paciente, para realizar el cierre de la comunicación bucosinusal, teniendo siempre en cuenta el crecimiento y desarrollo de cada paciente y no un tiempo fijo en general para todos ellos. Nos diferenciamos de otras personas que lo hacen en forma sistemática en tiempos quirúrgicos preestablecidos, igual para todos los pacientes (AU)

ABSTRACT

RESUMO A remoção de enxerto da crista ilíaca anterior é uma boa opção para a reconstrução de defeitos mandibulares após ressecções por trauma ou outras doenças. Para obtenção de resultados clínicos de excelência em cirurgias reconstrutivas com enxertos ósseos, um planejamento pré-operatório preciso e uma refinada técnica cirúrgica são essenciais. Portanto, este artigo descreve o uso de um template customizável, que é indicado para obter bloco de osso ilíaco livre para reconstruções mandibulares imediatas ou tardias após defeitos marginais ou segmentares. O template é baseado em um fragmento de metal maleável obtido de uma lata de bebida de alumínio. Ele é utilizado no transoperatório para demarcar o sítio doador do enxerto ósseo e é especialmente útil devido ao acesso limitado à cortical interna da crista ilíaca. O template customizável tem se mostrado uma ferramenta de fácil aplicação para determinar o tamanho do bloco de enxerto a ser coletado da região ilíaca, otimizando o tempo cirúrgico e evitando a remoção insuficiente de enxerto ósseo.


ABSTRACT Bone graft harvesting from the anterior iliac crest is a good option for reconstructing mandibular defects after trauma or other diseases. In order to achieve optimal clinical results in reconstructive surgeries with bone grafts, accurate preoperative planning and prestigious surgical technique are paramount. Therefore, this paper describes the use of a customizable template that is indicated for obtaining free iliac bone block for immediate or late mandibular reconstructions following marginal or segmental defects. The template is based on a piece of malleable metal obtained from an aluminum beverage can. It is used transoperatively to demarcate the bone graft donor site, being especially useful because of the limited access to the inner table of the anterior ilium. The described customizable template has been shown as a useful tool to easily determine the size of the bone block to be harvested from the iliac region, improving surgical time and preventing removal of insufficient bone graft.

ABSTRACT

Abstract Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor of the jaws, histologically characterized by the presence of agglomerates of cells with eosinophilic cytoplasm. The patient, a 62-year-old Caucasian woman, presented an intraosseous lesion in the mandibular symphysis. A clinical examination revealed a discrete volumetric increase with a hard consistency, palpable to extraoral and intraoral examinations. Imaging studies revealed an extensive radiolucent area, without defined limits, extending from the region of the right second premolar to the left canine. Incisional biopsy analysis indicated a diagnosis of CCOC. The treatment proposed was segmental resection of the mandible with a safety margin. After six months without recurrence, definitive mandibular reconstruction was performed using an iliac crest graft, followed by rehabilitation with implant-supported denture after five months. After three years of post-resection follow-up, the patient has shown no evidence of recurrence or metastasis. She continues to be under follow-up. To conclude, CCOC must be considered a malignant tumor with aggressive behavior. Previous studies have shown that resection with free margins is a treatment with a lower rate of recurrence. Nevertheless, long-term follow-up is necessary for such patients.

ABSTRACT

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm. It’s incidence approximately 1% of all oral tumors and 18% of all odontogenic tumors. More than 80% of cases of ameloblastoma occur in mandible. The ameloblastoma occurs in three variants solid or multicystic, unicystic, and peripheral. A painless expansion of the jaws is the most common clinical presentation. The correct diagnosis can be easily made with the help of plain X-rays and tissue biopsy. The standard management of ameloblastoma is marginal resection but sometimes a large tumor requires complete resection of affected part. Untreated tumors may lead to tremendous facial disfigurement, a severe malocclusion and pathological fractures of the jaw. Here we present a case of a young man with the chief complaint of facial asymmetry. The orthopantomogram of the patient was showing a multilocular radiolucency with Buccal and lingual cortical expansion. A diagnosis was made on the basis of the biopsy as multicystic ameloblastoma, and resection of the mandible was carried out. The mandibular primary reconstruction was done with avascular bilateral iliac crest bone graft. Long term prognosis showed satisfactory healing and good facial esthetics.

ABSTRACT

PURPOSE: There are no reports about bone graft and cell therapy for the osteonecrosis of femoral head (ONFH). We prospectively evaluated the clinical results of auto-iliac cancellous bone grafts combined with implantation of autologous bone marrow cells for ONFH. MATERIALS AND METHODS: Sixty-one hips in 52 patients with ONFH treated with bone graft and cell therapy were enrolled, and the average follow-up of the patients was 68 (60-88) months. Necrotic lesions were classified according to their size by the Steinberg method and location of necrosis. RESULTS: At the last follow-up, the percentage of excellent or good results was 80% (12/15 hips) in the small lesion group, 65% (17/26 hips) in the medium size group, and 28% (6/20 hips) in the large size group. The procedures were a clinical success in 4 of 5 hips (80%) of stage I, 23 of 35 hips (65.7%) of stage II, 7 of 18 hips (38.9%) of stage III, and 1 of 3 hips (33.3%) of stage IV grade, according to the Association Research Circulation Osseous grading system. Among the 20 cases with large sized necrotic lesions, 17 cases were laterally located and this group showed the worst outcomes, with 13 hips (76.5%) having bad or failed clinical results. CONCLUSION: The results of the present study suggested that patients who have a large sized lesion or medium sized laterally located lesion would not be good candidates for the head preserving procedure. However, for medium sized lesions, this procedure generated clinical results comparable to those of other head preserving procedures.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: Um número considerável de pacientes relata dor após coleta de enxerto da crista ilíaca anterior. Este estudo avaliou a eficácia da aplicação de bupivacaína embebida em uma esponja de gelatina absorvível (Gelfoam®) no local doador de osso e do uso parenteral de opioides no controle da dor pós-operatória. MÉTODO: Estudo prospectivo, duplo-cego, randomizado e controlado por placebo comparando a infiltração no período intraoperatório de 20 mL de bupivacaína (tratamento, grupo B) versus soro fisiológico (placebo) com Gelfoam embebida no local de coleta óssea da crista ilíaca em pacientes submetidos à cirurgia eletiva de coluna cervical. No período pós-operatório, a administração de cloridrato de hidromorfona (na sala de recuperação pós-anestésica e analgesia controlada pelo paciente) foi padronizada. Um escore de dor com base em escala visual analógica (EVA) com pontuação de zero a 10 foi usado para avaliar a intensidade da dor associada ao local doador. Os escores de dor e uso/frequência de narcóticos foram registrados 24 e 48 horas após a operação. Os médicos, pacientes, a equipe de enfermagem e os estatísticos desconheciam o tratamento usado. RESULTADOS: Os grupos eram semelhantes em idade, gênero e comorbidades. Não houve diferença significativa entre os grupos nos escores da EVA. As doses de narcótico foram significativamente menores no grupo B nos tempos de 24 e 48 horas (p < 0,05). CONCLUSÃO: Este estudo demonstrou que bupivacaína embebida em esponja de gelatina absorvível no local de coleta do enxerto ósseo de crista ilíaca (EOCI) reduziu o uso parenteral de opioides no pós-operatório.


BACKGROUND AND OBJECTIVE: A substantial number of patients report pain after graft harvest from the anterior iliac crest. This study examined the efficacy of local application of bupivacaine soaked in a Gelfoam® at the bone donor site in controlling postoperative pain and parenteral opioid use. METHOD: We performed a prospective, double-blind, randomized, placebo-controlled study comparing intraoperative infiltration of 20 mililiters of bupivacaine (treatment, group B) versus saline (placebo), with Gelfoam® soaked into the iliac crest harvest site for patients undergoing elective cervical spinal surgery. Postoperative administration of dihydromorphinone hydrochloride (post anesthesia care unit and patient-controlled analgesia) was standardized. A pain score based on a 10-point visual analog scale (VAS). was used to assess the severity of pain associated with donor site. Pain scores and narcotic use/frequency were recorded at the twenty-four and forty-eighth hour after the operation. Physicians, patients, nursing staff, and statisticians were blinded to the treatment. RESULTS: The groups were similar in baseline age, gender, and comorbidities. There was no significant difference between groups in VAS scores. Narcotic dosage, were significantly less in the Group B at 24 and 48 hours (p < 0.05). CONCLUSION: This study has demonstrated that bupivacaine soaked in gelfoam at the iliac bone graft harvest site reduced postoperative parenteral opioid usage.


JUSTIFICATIVA Y OBJETIVOS: Un número considerable de pacientes relata sentir dolor después de la recolección del injerto de la cresta ilíaca anterior. Este estudio evaluó la eficacia de la aplicación de bupivacaina empapada en una esponja de gelatina absorbible (Gelfoam®) en la región donadora del hueso y el uso parenteral de opioides en el control del dolor postoperatorio. MÉTODO: Realizamos un estudio prospectivo, doble ciego, aleatorio y controlado por placebo, comparando la infiltración en el período intraoperatorio de 20 mL de bupivacaina (tratamiento, grupo B) versus suero fisiológico (placebo) con Gelfoam empapado dentro de la región de la recolección ósea de la cresta ilíaca, en pacientes sometidos a la cirugía electiva de la columna cervical. En el período postoperatorio, la administración de clorhidrato de hidromorfona (unidad de recuperación y analgesia controlada por el paciente) se estandarizó. Un puntaje de dolor con base en la escala visual analógica (EVA) y un puntaje de 0 a 10 fueron usados para evaluar la intensidad del dolor asociada con la región donadora. Los puntajes de dolor y el uso/frecuencia de narcóticos se registraron 24 y 48 horas después de la operación. Los médicos, pacientes, el equipo de enfermería y los estadísticos no conocían el tratamiento usado. RESULTADOS: Los grupos eran similares en edad, sexo y comorbilidades. No hubo diferencia significativa entre los grupos en los puntajes de la EVA. Las dosis de narcótico fueron significativamente menores en el grupo B en los tiempos de 24 y 48 horas (p < 0,05). CONCLUSIONES: Este estudio demostró que la bupivacaina empapada en esponja de gelatina absorbible en la región de recolección del injerto óseo de la cresta ilíaca (EOCI) redujo el uso parenteral de opioides en el postoperatorio.

ABSTRACT

This paper presents the treatment protocol of maxillofacial surgery in the rehabilitation process of cleft lip and palate patients adopted at HRAC-USP. Maxillofacial surgeons are responsible for the accomplishment of two main procedures, alveolar bone graft surgery and orthognathic surgery. The primary objective of alveolar bone graft is to provide bone tissue for the cleft site and then allow orthodontic movements for the establishment of an an adequate occlusion. When performed before the eruption of the maxillary permanent canine, it presents high rates of success. Orthognathic surgery aims at correcting maxillomandibular discrepancies, especially anteroposterior maxillary deficiencies, commonly observed in cleft lip and palate patients, for the achievement of a functional occlusion combined with a balanced face.

ABSTRACT

The objective of this study was to investigate the bone regeneration of a "gold standard" (autograft) from iliac crest associated with cellular therapy in rabbits. A bone defect was created with 10x5x5mm in 28 rabbit mandibles. The control group animals (n=14) were repaired with autograft of iliac crest and the experimental group animals (n=14) received iliac crest autograft in association with mononuclear cells from the bone marrow of the femur. Weekly radiographs were taken of the surgery region and histological analyses was performed in seven animals in each group at 15 days and in seven animals of each group at 30 days after the surgery. A gradual increase of bone density was observed and the experimental animals presented the bone bridge in 85.7 percent (6/7) of the cases, while only 42.8 percent (3/7) of the animals in the control group presented this structure 28 days after the surgery. The histopathological parameters analyzed did not show any statistical difference between the control and experimental group in 15 and 30 days of analysis. The results suggest that the mononuclear cells from the marrow bone can better support the autograft regeneration in mandible defects in rabbits.


Avaliou-se a regeneração óssea de auto-enxerto, considerado "padrão ouro" da crista ilíaca associado à terapia celular da medula óssea em coelhos. Foi criado um defeito ósseo de 10x5x5mm na mandíbula de 28 coelhos, distribuídos em grupo-controle com, 14 animais, reparados com auto-enxerto de crista ilíaca, e grupo experimental com, 14 animais, em que o auto-enxerto foi associado a células mononucleares da medula óssea autógena do fêmur. Foram realizadas radiografias semanais da região operada e análise histológica em sete animais de cada grupo aos 15 e em sete de cada grupo aos 30 dias do pós-operatório. Houve aumento gradativo da densidade óssea, e 85,7 por cento (6/7) dos animais do grupo experimental e 42,8 por cento (3/7) do grupo-controle apresentaram formação de ponte óssea 28 dias após a cirurgia. Na análise histopatológica aos 15 dias, os enxertos foram facilmente visualizados e a atividade das células fagocitárias foi intensa. Já aos 30 dias, a visualização foi mais difícil e, quando possível, apenas um resquício foi visualizado. Os resultados sugerem que a adição de células mononucleares da medula óssea favorece a regeneração do auto-enxerto em defeitos mandibulares de coelhos.

ABSTRACT

La Implantología provocó una bisagra en la Rehabilitación Bucal moderna. La predictibilidad de los implantes llegó a porcentajes quizás impensados. Sin embargo, el giro evolutivo encuentra a la profesión hoy, cuestionando la ya vieja visión de colocar los implantes en el hueso residual existente. La reconstrucción del reborde maxilar exiguo puede entre otras formas ser realizada a partir de los injertos en bloque. Esta técnica antigua pero delicada y necesariamente precisa, disponía de mucho instrumental de mano pero carecía de un lugar de trabajo en la clásica mesa de Finochietto o en algúnotro lugar del quirófano, adecuado para esos fines. La mesa que hoy se publica es una herramienta eficaz para el manejo mas exacto de los injertos en bloque autólogos, homólogos, heterólogos o sintéticos, permitiendouna técnica más segura y precisa.

Cuando estamos ante la presencia de una patología tumoral, el cirujano se encuentra ante uno de los mayores desafíos que se le puedan plantear científicamente. Por un lado se debe tratar la patología con el margen de seguridad necesario para lograr la curación efectiva de la lesión; y por otro lado se debe restaurar en forma y función a la zona afectada. Si bien los dos aspectos fundamentales, para el paciente y su sicología, es mucho más importante este segundo aspecto. En la actualidad ha habido una evolución asombrosa en el campo de los métodos de diagnóstico, técnicas quirúrgicas y especialmente en todos los materiales utilizados para la reconstrucción; espelcialmente los referidos a la fijación rígida del tejido óseo y los implantes oseointegrados. El trabajo que se pone a consideración, reviste para nosotros una particular importancia, ya que se utilizó en forma conjunta un injerto óseo de la cresta ilíaca (hueso coxal) que servirá para la reconstrucción mandibular reemplanzando al maxilar afectado e implantes oseointegrados que nos servirán para la restauración protética posterior. La particularidad de esta técncia está dada porque estos implantes oseointegrados son colocados primero en la cresta ilíaca, se espera su período de oseointegración y con posterioridad se realiza el injerto con la cresta ilíaca y los implantes ya oseointegrados en conjunto en la zona receptora del maxilar inferior que se encontraba afectada por el tumor
