Tensile Mechanical Property Evaluation of Two Absorbable Sutures: Effects of Size and Types

摘要

Polymer type, suture configuration, and size had significant effects on tensile properties of two experimental sutures. While a large suture can bear more load, small sutures will have higher normalized tensile strength and modulus. Tensile modulus cannot be used to describe the flexibility of sutures of different configuration. PDO and PLGA sutures in this study showed significantly different failure mechanisms.
