The natural absorbable sutures of chromic catgut are prepared for this purpose as well as commercial synthetic<br>absorbable sutures made from polyglycolide.<br><strong>Methods</strong>: The analysis has been carried out following the standard test method for tensile strength and Young’s modulus of fiber ASTM C1557-03.<br>Measuring the diameter of each suture has been carried out with an optical microscope to determine the accuracy of manufacturers’ data. Tensile<br>testing has been performed to evaluate the tensile strength of each type of sutures. The modulus elasticity and strain (ϵ) obtained are also presented.<br><strong>Results</strong>: The results show that sutures made from braided synthetic material of polyglycolide (violet coated) present a tensile strength remarkably<br>superior (1070.292 MPa) to that of natural absorbable sutures of chromic catgut (392.276 MPa). Using optical macro microscope analysis,<br>monofilament sutures present less surface irregularities than multifilament polyglycolide sutures. Chromic catgut monofilament sutures present less<br>surface irregularities than multifilament polyglycolide.<br><strong>Conclusion</strong>: Tensile test of absorbable sutures was conducted in this research. Two types of absorbable sutures were investigated and compared. It is<br>found that sutures made from braided synthetic material of polyglycolide (violet coated) having much better tensile strength comparing with sutures<br>made from natural material (chromic catgut monofilament).</p> ER -
