ALMEIDA FILHO, Ildeu Afonso et al. Glenoumeral arthroplasty: polyester properties after methyl methacrylate contact. Acta ortop. bras. [online]. 2010, vol.18, n.3, pp. 158-161. ISSN 1413-7852. http://dx.doi.org/10.1590/S1413-78522010000300008.
OBJECTIVE: The authors studied the physical properties of polyester thread (ethibond) following methyl methacrylate contact in a biomechanics laboratory. METHODS: Strain at rupture, elasticity and traction deformity were evaluated using an Instron 4482 machine. The student-t test was used for the statistical analysis. RESULTS: There were no statistical differences between the two groups. CONCLUSION: It is concluded that methy metacrylate contact with polyester does not affect its elastic properties and traction resistance.
