PDS is an example of which type of suture?

PDS, or Polydioxanone, is categorized as an absorbable synthetic monofilament suture. As an absorbable suture, PDS is designed to degrade in the body over time through hydrolysis, allowing tissues to heal without the need for suture removal. The monofilament structure of PDS contributes to its smooth passage through tissues, reducing friction and minimizing tissue trauma during suturing.

The synthetic nature of PDS is essential as it offers more predictable absorption rates and mechanical properties compared to natural absorbable sutures, which can vary. This absorbable, synthetic monofilament design is particularly advantageous in surgeries where long-term support is needed during the healing process and where the risk of infection from suture material needs to be minimized.

Other types of sutures could differ in their absorbability, dosing forms (monofilament versus multifilament), or whether they are made from natural or synthetic materials, but PDS's specific characteristics clearly place it in the category of absorbable synthetic monofilament sutures.
