NEPTUN Plug Cement Restrictor

NEPTUN Plug is a resorbable cement restrictor for use in the medullary canal during cemented endoprosthetic procedures in orthopaedics and trauma surgery. The restrictor is designed to support targeted intramedullary pressurization and controlled cement distribution while preventing uncontrolled distal migration of bone cement.

The restrictor is manufactured from an elastic, gelatin-based biomaterial and dissolves completely at body temperature within a few days without leaving residues. Different diameters from 8 to 18 mm allow adaptation to individual anatomical requirements and support reproducible cementing procedures in everyday clinical use.

The corresponding insertion instrument enables depth-controlled placement of the restrictor within the medullary canal. Trial olives support precise sizing and allow straightforward integration into existing surgical workflows with minimal instrumentation.
