Resumo Objetivos Fazer uma revisão sistemática da literatura sobre a anatomia dos ligamentos meniscotibiais (LMTs) mediais, e apresentar os achados mais aceitos e a evolução das informações anatômicas sobre essa estrutura. Materiais e Métodos A busca eletrônica foi realizada nos bancos de dados MEDLINE/PubMed, Google Scholar, EMBASE e Cochrane, sem restrições de data. Os seguintes termos de indexação foram utilizados: anatomy AND meniscotibial AND ligament AND medial. A revisão seguiu as recomendações da declaração de Principais Itens para Relatar Revisões Sistemáticas e Metanálises (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA, em inglês). Foram incluídos estudos anatômicos do joelho, como dissecções de cadáveres, investigações histológicas e/ou biológicas, e/ou imagens da anatomia do LMT medial. Resultados Oito artigos atenderam aos critérios de inclusão e foram selecionados. O primeiro foi publicado em 1984, e o último, em 2020. A amostra total nos 8 artigos foi de 96 pacientes. A maioria dos estudos é puramente descritiva em relação aos achados morfológicos macroscópicos e histológicos microscópicos. Dois estudos avaliaram os aspectos biomecânicos do LMT, e um analisou a correlação anatômica com o exame de ressonância magnética. Conclusão A principal função do LMT medial, ligamento que se origina na tíbia e se insere no menisco inferior, é estabilizar e manter a posição do menisco no platô tibial. No entanto, há poucas informações sobre LMTs mediais, principalmente em termos de anatomia, vascularização e inervação.
Introduction Fractures of the distal third of the forearm are common in the pediatric population. Conservative treatment of an ipsilateral fracture of the distal ulna metaphysis is one of the risk factors for loss of reduction. Percutaneous fixation of the fracture with K-wires is recommended. This study aims to evaluate the outcome of percutaneous fixation of both bones performed as the primary treatment. Materials and Methods A randomized, open, prospective, clinical trial was conducted, including skeletally immature patients who underwent surgery for fractures of the distal radius and ulna. They were randomized into two groups, one with fixation only of the radius fracture and the other with fixation of both the radius and the ulna fractures, and they were followed clinically and radiologically for up to 12 weeks postoperatively. Results Sixteen children were selected. In the intraoperative period, fluoroscopy was activated for a longer time when fixing the ulna (p = 0.011) and the surgical time was longer in this group (p = 0.014). In the postoperative evaluations, the group whose surgery involved the fixation of both bones had a lower postoperative pain score (p <0.001) and less time away from school (p <0.001). Conclusions In this study, postoperative pain and absence from school were both less when fixation of the radius and ulna was performed. Evidence Level II; Randomized Controlled Study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
