  • Patent number: 9439681
    Abstract: The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

  • Patent number: 8968374
    Abstract: A biocompatible interference screw for soft tissue or bone-to-bone fixation comprises a screw body extending from a screw head to a distal tip of the screw. The screw body has an outer surface, and comprises polyether-ether-ketone (PEEK) material. Advantageously, the body outer surface has a textured surface finish for substantially improving pull-out strength of the interference screw. The textured surface finish is textured, in preferred embodiments, with a minimum of approximately 16 micro inches of surface roughness. The screw head comprises a tapered square keyhole for receiving a distal end of a driver instrument. The screw comprises a series of threads, which have a relatively smooth profile, in order to prevent graft tissue laceration as the screw is being inserted. The distal tip of the screw body comprises a narrow tip, and a distal end of the screw body is angled inwardly toward the narrow distal tip.

  • Patent number: 7556638
    Abstract: Endosteal fixation of a ligament graft with a bioabsorbable interference screw installed in a retrograde manner in ACL reconstruction. The bioabsorbable interference screw is insert-molded with a length of suture extending from the distal tip of the screw for pulling the interference screw into the joint and into position for retrograde insertion at the top of the tibial tunnel. The interference screw has a cannulation extending partially through the screw from the leading tip. The cannulation is shaped to receive a correspondingly shaped driver. The driver is inserted into the tibial tunnel to engage the screw. By turning the driver, the interference screw is turned into the tibial tunnel in a retrograde manner. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.

  • Patent number: 7520898
    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.

  • Patent number: 7500990
    Abstract: A surgical method for loading ligament grafts into a joint. A longitudinal socket formed in a bone is intersected by a transverse pin. A flexible strand is drawn with the pin through the bone. A looped portion of the strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the strand remaining 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 a transverse implant.

  • Patent number: 7485136
    Abstract: A jamming retainer for fixing a ligament in a bone tunnel without excessive sideways pressure on the ligament that may result in tissue necrosis the jamming retainer including a substantially rigid body with a bore or loop for receiving a ligament or tendon and a bore or ring for receiving a suture for towing the jamming retainer and ligament or tendon through a bone tunnel. Once positioned, the jamming retainer is fixed in the bone tunnel with an interference screw.

  • Publication number: 20090024174
    Abstract: Procedures for the fusion of the sacroiliac joint advantageously make use of an implant selected to distract the joint upon insertion and to maintain or increase tension upon insertion. The implant can have a varying structure along its length. In some method described herein for fusing the sacroiliac joint using an implant, an implant is screwed into the sacroiliac joint between the sacrum bone and the iliac bone. The implant comprises a shaft, a tool engagement flange at top end of the shaft, a pointed tip comprising no more than about 20 percent of the length of the screw, and threads spiraling around the shaft. For screws of particular interest, the volume displacement perpendicular to the shaft increases at least about 5 percent from a point adjacent the tip to a point near the top of the shaft. Some of the desirable screw designs can be used in other orthopedic application, especially situations involving varying bone hardness.

  • Publication number: 20080177336
    Abstract: A method and apparatus for performing a surgical repair may involve fixation of a repair material, such as a ligament or tendon in knee ligament repair procedure, to an internal cortical contact area in a bone. The cortical bone contact area may be located immediately adjacent an opening in the bone's surface through which the repair material extends. The repair material may be engaged with the contact area by way of a fixation device, such as a device that is attached to the repair material and functions as a stop member. An illustrative fixation device may include an annular portion with an aperture through with the repair material passes. The repair material may be attached to a securing portion that extends from the annular portion.
