    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.

  • Publication number: 20040059415
    Abstract: A surgical implant for securing ligament grafts into a joint. The implant is formed entirely of allograft cortical bone, and has a tapered tip with a suture eye. A length of suture is knotted or looped through the eye. The suture is used to draw the implant transversely through a looped graft construct to fix the graft by spanning a bone socket, for example. In a preferred embodiment, the implant is used for knee ligament repair by forming a longitudinal socket in a bone. A flexible strand is drawn with the pin through the bone. A looped portion of the flexible strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the flexible strand remain accessible on either side of the bone. The ligament graft is captured within the strand loop protruding from the entrance to the socket. The strand is retracted into the socket, drawing the graft into the socket by pulling on the accessible ends of the flexible strand. The graft is fixed in the socket using the transverse implant.

  • Publication number: 20040030341
    Abstract: In order to form positive connections with human or animal tissue parts, particularly bones, implants (7) are used that at least partially consist of a material that can be liquefied by means of mechanical energy. Particularly suitable materials of this type are thermoplastics (e.g. resorbable thermoplastics) or thixotropic materials. The implants (7) are brought into contact with the tissue part, are subjected to the action of ultrasonic energy and are simultaneously pressed against the tissue part. The liquefiable material then liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, it is positively joined thereto. The implantation involves the use of an implantation device comprising a generator (2), an oscillating element and a resonator (6), whereby the generator (2) causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator (6).

  • Patent number: 6679889
    Abstract: Apparatus and methods for conditioning and pre-tensioning soft tissue grafts during joint repair surgery, such as during repair of the anterior cruciate ligament (ACL). The inventive apparatus is advantageously adapted and configured so as to enable a surgeon to independently apply a desired tensile load onto individual strands of a multiple-stranded soft tissue graft, such each of a pair of ham strings. The inventive methods advantageously ensure that each strand of a multiple-strand soft tissue graft is adequately tensioned so as to both “condition” the graft to prevent subsequent stretching, relaxation or elongation following surgery, which can destabilize the joint, and pre-tension each strand of the graft to a desired amount so that each significantly contributes to the strength and stability of the joint, thus resulting in a stronger and more durable joint.

  • Publication number: 20030065391
    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.
