Bone implants |
摘要 |
A prosthetic joint for replacing a natural joint in a body includes a first prosthetic component of the prosthetic joint which, when implanted into a first resected bone of the natural joint has a junction between the implanted component and the bone. The joint further includes a second prosthetic component of the prosthetic joint which, when implanted into an adjacent resected bone of the natural joint, articulates with the first component. A microporous membrane surrounds the first prosthetic component and is secured to the first prosthetic component and, when implanted in a body, is secured to bone surrounding said first prosthetic component, thereby sealing the junction against ingress of particles, but permitting liquids to pass through said membrane without restricting articulation of the joint.
