ThenThe invention relates to the modular use of open-pore metal sponges asnthermoset bone substitute in trauma surgery and orthopedics, whosenEspecially suitable for the permanent replenishment of post-traumatic andnOsteoporosis or tumor-related bony defects of elderly patientsnoffering. It becomes a spongy-metallicnImplant proposed as alloplastic bone substitute made exclusively fromnone or more connected, graduated open-pored metal sponge structuresnexists, which are assembled as modules of a modular system ornindividually formed on the basis of a costum made CT evaluation.nThe preferred material is titanium or a titanium alloynCommitment; The metal sponge thus formed is characterized by anvery high porosity.nFor thenProduction of the structure uses a special method,nthat makes it possiblenproduce relatively thick webs compared to the prior artnand thus a high dimensional stabilitynto ensure the metal sponge.nAs a result, the implant according to the invention comes without supportingnMetal core, especially since it is the completenosseousnPenetration allows. |
