Resumo: PURPOSE: The aim of the present study was to assess, in cadavers, the resistance to medial traction of the posterior and anterior layer of the rectus abdominis muscle sheath. METHODS: An anatomical, prospective, self-controlled study was carried out in 20 male cadavers. An evaluation of the tension of the posterior and anterior layers of the rectus abdominis muscle sheath was performed following anatomical dissection of these structures. The traction necessary to advance the tissue ten millimeters was assessed using an analogic dynamometer. RESULTS: There was no significant statistical difference between the necessary traction at various levels of the anterior and posterior layers of the rectus sheath. However, medial advancement of the anterior layer of the rectus sheath required more traction strength than did advancement of the posterior layer to the midline. CONCLUSION: There is no difference in the tensile strength in the various levels of the anterior and posterior layers of the rectus sheath; however, medial advancement of the the anterior layer required more traction strength.

MÉTODOS: Vinte cadáveres adultos foram submetidos à dissecção da parede abdominal anterior. Foram feitas alças com fio de náilon no plano aponeurótico em oito pontos diferentes na lâmina anterior e na lâmina posterior da bainha do músculo reto do abdome, sendo quatro destes pontos supra-umbilicais e quatro infra-umbilicais. Com o uso de um dinamômetro analógico, foi verificada a força necessária para o avanço medial de dez milímetros destes dezesseis pontos. RESULTADOS: Não foram encontradas diferenças significantes de medidas da resistência à tração entre os diferentes níveis da aponeurose anterior e posterior, mas quando se comparou as medidas obtidas na aponeurose anterior às obtidas na posterior verificou-se que a aponeurose anterior necessitou de maior força de tração para o avanço medial. CONCLUSÃO: Não há diferença de tensão ao longo da aponeurose anterior e posterior. A aponeurose anterior é mais resistente à tração medial quando comparada à posterior.Federal University of São Paulo Postgraduate ProgramUniversidade Federal de São Paulo (UNIFESP) Department of Surgery Division of Plastic SurgeryUNIVÁS Department of Colon and Rectum SurgerySanta Casa Porto Alegre Plastic Surgery UnitUniversity Santo AmaroUNIFESP, Postgraduate ProgramUNIFESP, Department of Surgery Division of Plastic SurgerySciELOSociedade Brasileira para o Desenvolvimento da Pesquisa em CirurgiaUniversidade Federal de São Paulo (UNIFESP)UNIVÁS Department of Colon and Rectum SurgerySanta Casa Porto Alegre Plastic Surgery UnitUniversity Santo AmaroAmorim, Carlos Roberto [UNIFESP]Nahas, Fabio Xerfan [UNIFESP]Souza, Virgínio Cândido Tosta deEly, Pedro BinsSilveira, Romar Ângelo Barbato [UNIFESP]Novo, Neil Ferreira [UNIFESP]Ferreira, Lydia Masako [UNIFESP]2015-06-14T13:37:00Z2015-06-14T13:37:00Z2007-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion255-259application/pdfhttp://dx.doi.org/10.1590/S0102-86502007000400005Acta Cirurgica Brasileira.
