Abraçadeira de náilon: resistência à tração em testes físicos e seu emprego como cerclagem no fêmur de cães

Abstract

The cramp is a belt made of nylon 6.6 (polyamide – PA). It has been applied after sterilization in several surgical procedures, amongst these, the reduction of fractures of lengthy bones. In this study, firstly, it was evaluated tensile strength of these cramps using specific tests of physical effort, carried through in its natural and autoclaved conditions. Thereafter, qualitative evaluation of resistance was carried out applying the nylon cramp in oblique fractures reduction of femur in dogs, verifying the tensile strength and security of the safety catch after its fasten. The polyamide belt showed appropriate resistance to autoclaving, physical efforts and its application in the focus of fracture. Thus, it can be concluded that the nylon cramp has tensile strength in its natural state as well as in autoclaved condition and it can be an option in treatment of oblique fractures of femur.
