nonreabsorbable

Nonreabsorbable, also called nonabsorbable, refers to materials that do not break down or get absorbed by the body over time. In medical contexts, nonreabsorbable materials are chosen when long-term or permanent mechanical support is required, remaining in the implanted site for years or indefinitely. This is in contrast to absorbable (reabsorbable) materials, which are designed to be gradually degraded and resorbed as healing occurs.

Common nonreabsorbable materials include synthetic polymers such as polypropylene, nylon, and polyester used for sutures and surgical meshes, as well as metals like stainless steel and titanium. Expanded polytetrafluoroethylene (ePTFE) is another nonabsorbable option used in vascular grafts and implants. The choice of material depends on the clinical need, the required duration of support, and the desired tissue response.

Applications of nonreabsorbable materials include sutures that must maintain strength over long periods, meshes for hernia repair and pelvic floor reconstruction, and various implants or grafts intended to remain in the body permanently. Nonreabsorbable sutures are favored when prolonged wound support is essential, while nonabsorbable meshes provide durable structural reinforcement in the repaired area.

Risks associated with nonreabsorbable materials include chronic inflammation or foreign body reactions, infection, erosion into adjacent tissues, and, in some cases, the need for removal if complications arise. Some materials may also interfere with imaging or cause patient discomfort over time. Proper selection and technique are important to balance long-term stability with potential risks.
