NEPTUN Plug - Resorbable Cement Restrictor

The NEPTUN Plug is a resorbable cement restrictor designed for use in the medullary canal during cemented endoprosthetic procedures in orthopaedics and trauma surgery. It stabilizes the bone cement application, prevents uncontrolled distal migration of the cement, and enables targeted pressure build-up in the femoral shaft. This ensures even distribution of the cement within the surrounding bone bed for optimal fixation. The restrictor is available in diameters from 8 to 18 mm (in increments of 2 mm) and adapts flexibly to individual anatomical conditions. Made from an elastic, gelatin-based biomaterial, it dissolves completely at body temperature within a few days, leaving no residue. Removal is not required, even in revision surgery.
