1. Biomechanical Evaluation of Different Tibial Fixation Methods in the Reconstruction of the Anterolateral Ligament in Swine Bones
Resumo Objetivo Avaliar a força de resistência à tração de diferentesmétodos de fixação tibial na reconstrução do ligamento anterolateral (LAL). Além disso, comparar os mecanismos de falha da fixação tibial dessa reconstrução em joelhos suínos. Métodos Foram usados 40 membros recém-congelados de suínos, divididos em quatro grupos de de

2. BIOMECHANICS OF BONE BLOCK GRAFT MODELS OF DIFFERENT GEOMETRY
RESUMO Objetivo: Avaliar o comportamento mecânico de enxertos ósseos em blocos com geometrias diferentes usando modelos de madeira. Métodos: Montagens com “enxertos” de perfil retangular (G1) e trapezoidal (G2), fixadas com placas de compressão dinâmica de 3,5 mm e oito orifícios, foram submetidas a ensaios não destrutivos de flexão, com a carg

3. The diagnosis and treatment of tibial intercondylar chondroblastoma
OBJECTIVES: To investigate the diagnosis and treatment of tibial intercondylar chondroblastoma. METHODS: We retrospectively analyzed the diagnosis and treatment of 12 patients with tibial intercondylar chondroblastoma admitted to the orthopedics department from May 2011 to February 2016; among them were 4 males and 3 females aged 10-19 years, with an avera

4. Application of bioabsorbable screw fixation for anterior cervical decompression and bone grafting
OBJECTIVES: To examine the application of bioabsorbable screws for anterior cervical decompression and bone grafting fixation and to study their clinical effects in the treatment of cervical spondylosis. METHODS: From March 2007 to September 2012, 56 patients, 36 males and 20 females (38-79 years old, average 58.3±9.47 years), underwent a novel operation.

5. Biomechanical performance of Bio Cross-Pin and EndoButton for ACL reconstruction at femoral side: a porcine model
Abstract Introduction The method of graft fixation is critical in anterior cruciate ligament (ACL) reconstruction surgery. Success of surgery is totally dependent on the ability of the implant to secure the graft inside the bone tunnel until complete graft integration. The principle of EndoButton is based on the cortical suspension of the graft. The Cross-P

6. Graft tendon slippage with metallic and bioabsorbable interference screws under cyclic load: a biomechanical study in a porcine model
Introduction The rupture of the anterior cruciate ligament (ACL) is the most common type of knee injury. Reconstructive surgery is the ‘gold standard’ treatment. During the immediate post-operative period, the fixation of the graft is entirely dependent on the ability of the grafted implant to be secured inside the bone tunnel under the cyclical loads a

7. Comparative study of the fixation and integration of "onlay" bone grafts with the use of n-Butyl-2-cyanoacrylate or titanium screw. Histological, immunohistochemical and CT in rabbits / Estudo comparativo da fixação e integração de enxertos ósseos onlaycom o uso de n-Butil-2-Cianocrilato ou parafuso de titânio. Estudo histológico, imunohistoquímico e tomográfico em coelhos
Alguns trabalhos sobre a resposta do tecido ósseo ao Cianocrilato podem ser encontrados na literatura, embora nenhum deles avalie a resposta histológica e a fixação de enxertos ósseos onlay com o N-Butil-2-Cianocrilato (Indermil™). O objetivo do estudo proposto foi (1) analisar a manutenção do volume de enxertos ósseos onlay fixados à mandíbu

8. ANALYSIS EX VIVO BIOMECHANICS OF TWO METHODS OF OSTEOSYNTHESIS OF PELVIS IN DOGS / ANÁLISE BIOMECÂNICA EX VIVO DE DOIS MÉTODOS DE OSTEOSSÍNTESE DE PELVE EM CÃES
Approximately 25% of all fractures in dogs involve the pelvis, of which 18-46% are iliac fractures. Conservative treatment can be performed in simple cases where minimum displacement occurs fractured fragments. However when there is severe displacement of the fragments, pelvic canal narrowing and involvement of weight bearing, surgical fixation is indicated.

9. Analise da estabilidade do reposicionamento inferior da maxila sem a utilização de enxerto interposicional : um estudo cefalometrico retrospectivo / Analysis of stability after maxillary inferior repositioning without interpositional graft : a retrospective cephalometric study
The true vertical maxillary deficiency is a characteristic of Short Face Syndrome (CFS), in these patients, the inferior repositioning of the maxilla is indicated in order to provide a better facial esthetics and improved function. But this surgical movement has been described as the most instable movement, and interpositional autogenous bone graft usually i

10. Enxerto Ãsseo autÃgeno mantido em diferentes meios de armazenagem no perÃodo transcirÃrgico: AnÃlise histomorfomÃtrica em coelhos
The success of autogenous bone graft is related to the graft cells viability transferred to receptor site. During surgical bone grafting procedures, a time passes by the graft removal till its fixation in receptor site. Various media for temporary storage of bone grafts during the surgical procedure have been suggested to minimize the deleterious effect duri

11. Evaluation of tissue response due to different fixation materials in autogenous bone grafts: microscopic morphological analysis / Avaliação da resposta tecidual frente a diferentes materiais de fixação em enxertos ósseos autógenos: análise microscópica morfológica
Autogenous bone grafts have been largely used for the reconstruction of severely atrophic ridges. The fixation of these grafts plays an important role in bone graft repair, leading to the integration to the receptor bed and early revascularization. Resorbable plates and screws are being developed in an attempt to minimize some negative aspects of the metalli

12. Tendon Graft—Ulna Fixation in Distal Radio-Ulnar Joint Stabilisation; Biomechanical Comparison of Three Graft-Bone Fixation Methods
A common distal radio-ulnar joint (DRUJ) stabilisation procedure uses a tendon graft running from the lip of the radial sigmoid notch to the ulnar fovea and through a bony tunnel to the ulnar shaft, before being wrapped round the distal ulna and sutured to itself. Such graft fixation can be challenging and requires a considerable tendon length. The graft len
