【発明の名称】人体の関節を外科的処置するための使い捨て可能な関節接合間隔保持装置
Document Type and Number:
Japanese Patent JP2003529440
Kind Code:
A
Abstract:
A disposable articulated spacing device for the treatment of joints of the human body, particularly for temporary replacing an explanted joint prosthesis, comprises at least one first member (2) able to be secured to a first articulation end and at least one second member (3) able to be secured to the other articulation end, both said members (2, 3) being pre-formed and made entirely of biological compatible and porous material suitable to be added with pharmaceutical and therapeutical products; the pre-formed members (2, 3) are reciprocally coupled in an articulated manner to maintain a suitable joint space and at least a partial articulation for the time necessary to perform the further implantation of a joint prosthesis. The biologically compatible and porous material is chosen among metals, metallic alloys, organo-metals, ceramics, glasses, plastics materials, bone cements and combinations thereof. The articulated spacing device maintains a suitable space in the joint seat while allowing a considerable articulated mobility, and re-establishes suitable conditions of implantation of a new permanent joint prosthesis.
