Abstract: A composite vertebroplasty cement for positioning in a void in a vertebral body so as to treat a compression fracture in that vertebral body, the composite vertebroplasty cement comprising: a ceramic component for integrating with the vertebral body so as to treat the compression fracture; and a sealing component for sealing the void in the vertebral body so as to maintain the composite vertebroplasty cement within the void in the vertebral body. A composite vertebroplasty cement for positioning in a void in a vertebral body so as to treat a compression fracture in that vertebral body, the composite vertebroplasty cement comprising: a conventional PMMA bone cement component for integrating with the vertebral body so as to treat the compression fracture; and a sealing component for sealing the void in the vertebral body so as to maintain the composite vertebroplasty cement within the void in the vertebral body.

Abstract: A method and apparatus for reconstructing a ligament using a graft ligament support block which comprises a body, and a graft hole and a transverse fixation pin hole extending through the body, with both the graft hole and the fixation pin hole preferably extending substantially perpendicular to the longitudinal axis of the body. A graft ligament is looped through the graft hole, and the support block is advanced into the bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with the fixation pin hole. Then the support block is secured in place by pinning the support block within the tunnel, i.e., by advancing a fixation pin along the transverse tunnel in the host bone and into the fixation pin hole in the support block.

Abstract: A graft ligament is looped through a graft hole in a graft ligament support block, and the graft ligament support block is mounted to an installation tool. Then the installation tool is used to advance the graft ligament support block into a bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with a transverse fixation pin hole in the graft ligament support block. Then the graft ligament support block is secured in place by pinning the graft ligament support block within the tunnel, i.e., by advancing a transverse fixation pin along the transverse tunnel and into the transverse fixation pin hole in the graft ligament support block. Then the installation tool is detached from the graft ligament support block and withdrawn from the surgical site.
