Resumo(s)
As fraturas do rádio são a terceira fratura de osso alongado mais comum em cães, afetando principalmente a metade distal do osso. Estas fraturas ocorrem com maior frequência em cães de raças pequenas associadas a uma elevada taxa de complicações. O tratamento pode envolver desde métodos conservativos a técnicas cirúrgicas, sendo a redução aberta com fixação com placa e parafusos a abordagem mais utilizada. Este estudo em cadáver pretendeu verificar a viabilidade de realizar um novo acesso cirúrgico pela face caudal do rádio, desenvolvido com base no acesso de Henry modificado, descrito em Medicina Humana, e adaptado à anatomia do cão. O objetivo visa reduzir possíveis complicações pós-operatórias ao proporcionar uma maior cobertura por tecidos moles sobre a placa de osteossíntese. O acesso proposto foi realizado um total de vinte repetições, utilizando dez cadáveres da espécie canina de diferentes pesos. Em apenas dez membros, realizou-se uma osteotomia como simulação de fratura e estabilização com placa e parafusos. Os resultados revelaram uma exposição adequada da face caudal do rádio, beneficiando de uma cobertura tecidual ótima, o que pode reduzir o risco de infeção, irritação tecidual e otimizar a regeneração óssea. Adicionalmente, a técnica apresentou vantagens na manipulação dos implantes e no encerramento dos bordos cutâneos, podendo contribuir para a redução do tempo cirúrgico. Apesar das limitações inerentes a um estudo em cadáver e à ausência de comparação direta com acessos convencionais, os resultados sugerem que a adaptação do acesso de Henry para a espécie canina é viável e promissora, contribuindo para o avanço das técnicas de osteossíntese e abrindo caminho para futuras investigações que possam validar o seu uso na prática clínica
Radial fractures are the third most common long bone fracture in dogs, primarily affecting the distal half of the bone. These fractures occur more frequently in small breed dogs and are often associated with a high rate of complications. Treatment options range from conservative methods to surgical techniques, with open reduction and internal fixation using plates and screws being the most commonly employed approach. This cadaveric study aimed to assess the feasibility of a novel surgical approach through the caudal surface of the radius, developed based on the modified Henry approach described in Human Medicine and adapted to canine anatomy. The goal is to reduce potential post-operative complications by providing greater soft tissue coverage over the osteosynthesis plate. The proposed approach was performed a total of twenty times using ten canine cadavers of various body weights. In only ten limbs, an osteotomy was performed to simulate a fracture, followed by stabilization with a plate and screws. The results showed adequate exposure of the caudal surface of the radius, benefiting from an optimal soft tissue coverage, which may reduce the risk of infection, soft tissue irritation, and optimize bone regeneration. Additionally, the technique demonstrated advantages in implant handling and ease of skin closure, potentially contributing to reduced surgical time. Despite the limitations inherent to cadaveric studies and the absence of direct comparison with conventional approaches, the results suggest that the adaptation of the Henry approach to the canine species is feasible and promising, contributing to the advancement of osteosynthesis techniques and paving the way for future research to validate its use in clinical practice
