发明名称 Joint prosthesis
摘要 <p>A cylindrical, fibrous, porous joint spacer is provided, having excellent properties, flexibility of formation, and operability, which is intended to be implanted as a prosthesis between bones (8,9) to be joined together. The joint spacer of the present invention can be formed from a strip of fabric (1), which is comprised of bioabsorbable fibers and made by a knitting, weaving, non-woven or other technique. The fabric (1) is typically relatively narrow (e.g. 1 to 10 mm wide) and thin (e.g. 0.1 to 1.0 mm thick), depending on the intended application of the prosthetic device to be formed from the fabric (1). The joint spacer of the present invention is made by wrapping said fabric (1) to yield a cylindrical body (2); and fixing the free end of the fabric (1) to the surface of the cylindrical body (2) so formed. The joint spacer of the present invention can be implanted in conjunction with one or more fixation parts (14',14''), to hold the joint spacer in place between the bones (15,16) to be joined. &lt;IMAGE&gt;A cylindrical, fibrous, porous joint spacer is provided, having excellent properties, flexibility of formation, and operability, which is intended to be implanted as a prosthesis between bones (8,9) to be joined together.
