Which statement about absorbable sutures is incorrect?

The first statement about chromic gut sutures accurately describes their characteristics. Chromic gut sutures are indeed known to have a moderate tissue reaction due to the nature of the materials used in their composition, and the claim of a half-life of 5-6 days is in line with their absorption properties.

However, it's important to note that chromic gut sutures do not have poor tensile strength; rather, they provide a reasonable amount of tensile strength for their expected duration of application. Thus, this statement is misleading and does not represent the characteristics of chromic gut sutures appropriately.

The remaining statements correctly represent the absorption times and reactions of other types of absorbable sutures. Polyglactin 910 does indeed have a longer absorption time and minimal tissue reaction, while Poliglecaprone 25 is recognized for its prolonged absorption time and fair tensile strength, both of which align well with the established information in surgical practice.
