<p>The invention relates to the modular use of open-pore metallic sponges as duroplastic bone replacement in accident surgery and orthopedy, the application thereof being particularly suitable for the permanent filling of post-traumatic bone defects and bone lesions related to osteoporose or tumours in the case of elderly patients. According to the invention, a spongy metallic implant is provided as alloplastic bone replacement. Said implant solely consists of one or more connected, graduated open-pore metallic sponge structures which are configured as a modular system or are individually formed on the basis of a costum made CT evaluation. Preferably, titanium or a titanium alloy is used as material; the metallic sponge formed therewith is characterized by a very high porosity. A special method is used for producing the structure, allowing thereby the production of relatively thick webs in comparison to those known in prior art and thus ensuring a high amount of dimensional stability of the metallic sponge. For this reason, the implant does not require a supporting metallic core, especially since it allows the complete penetration of the bone.</p> |
