Avaliação clínica e radiográfica da cobertura acetabular à cabeça femoral, após aplicação de cunha sacroilíaca em cães

O objetivo deste estudo foi aplicar cunhas de polímero de mamona poroso com adição de cálcio na junção sacroilíaca, avaliar clinicamente a interferência da técnica na deambulação dos cães e, radiograficamente, verificar o aumento da cobertura acetabular à cabeça femoral. Para tal, foram utilizados oito cães, adultos, com peso entre 16,5 a 32 kg, quatro normais e quatro displásicos, porém sem sintomatologia dolorosa. Na junção sacroilíaca esquerda foi aplicada cunha de 30°. Foram realizadas avaliações clínicas pós-operatórias, perimetria da coxa, avaliação do apoio do membro do lado operado, aferição dos ângulos de flexão e extensão. Para avaliação da ventroversão acetabular foram empregados os métodos radiográficos do ângulo de Norberg e a porcentagem de cobertura acetabular. Os animais foram avaliados no pré-operatório, pós-operatório imediato, 30, 60 e 90 dias. Para a avaliação clínica, perimetria da coxa, avaliação da claudicação e apoio do membro, flexão e extensão, também se incluiu os períodos de sete, 14 e 21 dias. Observou-se na avaliação radiográfica aumento da cobertura acetabular logo no pós-operatório imediato, tanto no método do ângulo de Norberg quanto na porcentagem de cobertura acetabular. Não houve interferência na deambulação dos animais, uma vez que todos retornam a deambulação normal ao término do período de avaliação. Do ponto de vista clínico, a cunha comportou-se como biopolímero, suportando a aplicação de parafuso em efeito compressivo. A técnica promove aumento da cobertura acetabular, comprovado radiograficamente, podendo ser empregada em cães displásicosThe goal of this study was to apply castor oil porous polymer wedges with addition of calcium in the sacroiliac joint; to evaluate clinically the interference of the technique in the walking of dogs and, radiographically, to check the increasing of the acetabular covering to the femoral head. In order to accomplish it, eight adult dogs weighting 16.5 - 32 kg were used, four of them normal and four of them dysplastic, although without painful symptomatology. In the left sacroiliac joint was applied 30 wedge. Postoperative clinical evaluations, thigh perimetry, evaluation of the support of the operated side member, gauging of the flection and extension angles were carried out. To evaluate the acetabular ventroversion the Norberg angle radiographic methods and the percentage of acetabular covering were used. The animals were evaluated in the preoperative, immediate postoperative, 30, 60 and 90 days. To the clinical evaluation, thigh perimetry, claudication evaluation and member support, flection and extension, they were also included the periods of seven, fourteen and twenty-one days. It was observed in the radiographic evaluation an increasing of the acetabular covering soon in the immediate postoperative, in both the Norberg angle method and the percentage of acetabular covering. There wasn´t interference in the walking of the animals, considering that all of them recover the regular walking at the end of the evaluation period. From the clinical point of view, the wedge behaved as biopolymer, bearing the screw application in compression effect. Such technique promotes the acetabular covering increase, radiographically proven, and it can be employed in displastic dog

Avaliação radiográfica da cobertura acetabular à cabeça femoral, após osteotomia tripla e aplicação de cunha sacroilíaca, em pelve de cadáveres de cães

Na tentativa de evitar algumas das dificuldades associadas à osteotomia pélvica tripla (OPT), foi desenvolvido experimentalmente o método de aplicação de cunha na junção sacroilíaca para aumentar a ventroversão acetabular. O objetivo deste estudo foi aplicar as técnicas de cunha sacroilíaca e OPT em cadáveres e avaliar radiograficamente a eficácia da ventroversão acetabular. Para tal, foram utilizados 10 cadáveres de cães, adultos, com 15-25 kg. em cada hemipelve direita foi realizada OPT com placas de 20° e 40°. Na hemipelve esquerda foram aplicadas cunhas nas articulações sacroilíacas de 20° e 40°. Avaliações radiográficas em projeções ventrodorsais foram realizadas para mensuração da cobertura acetabular à cabeça femoral nas duas técnicas. de acordo com os dados obtidos pode-se observar que não houve diferença entre a técnica de OPT e o uso de cunha sacroilíaca utilizando implantes de 20° e 40°, mas ocorreu diferença significativa (p<0,05) entre os cães antes e após a aplicação dos implantes de 20° e 40°, e também entre os que receberam implantes de 20° e os de 40°. A aplicação de cunha sacroilíaca produziu resultados semelhantes à OPT, e também se mostrou como de mais fácil aplicação.Attempting to avoid difficulties associated to triple pelvic osteotomy (TPO), the sacroiliac wedge method was experimentally developed to increase the acetabular ventroversion. The goal of this study was to apply the techniques of sacroiliac wedge and TPO to canine cadavers and radiographically evaluate the efficacy of acetabular ventroversion. Ten cadavers of adult dogs weighting 15-25 kg were used. To each right hemipelvis the technique of TPO with 20° and 40° plates was applied. In the left hemipelvis, 20° and 40º wedges in the sacroiliac joint were applied. Radiographic evaluations in standard projections were carried out for measurement of the acetabular covering of the head of the femur in the two techniques. There was no significant differences between TPO and the use of sacroiliac wedge using implants of 20° and 40°, however a significant difference (p<0,05) could be observed before and after application of the 20° and 40° implants, as well as between those that received 20° and of 40° implants. The application of sacroiliac wedge produced similar results of those observed in TPO, and it is more feasible.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Experimental model of a bone gap by radial ostectomy in rabbits

A lot of experimental models have been used to study the process of a fracture’s consolidation, but the problem is that due to anatomic, biologic and technical differences, these models do not always have appropriate parameters for the exact species, for which the experiment was done. The rabbit is an experimental model that is widely used in studies involving bone physiopatology in the face of fractures and their different types of treatment, corresponding to approximately 35% of all the musculoskeletic system’s scientific studies. Several surgical techniques have been used on rabbit’s bone for experimental studies, and the partial ostectomy of the radius bone is one of them. In this study, 14 rabbits (Oryctolagus cuniculus familiaris), males, adults, of white New Zeland breed, neutered, with weight between three and four kilograms, were used. Clinically, the animals did not present any alterations that compromised the study. There were evaluated through radiographic exam on days zero, 30 and 60 after the surgery, visualizing the quality of the gap and the relevant alteration of bone proliferation. The histologic exam elucidated the neoformed bone architecture and its components. The efficacy of the techinique was proved and it could be reproduced for many purposes in orthopedic surgery
