Abstract: A sterile holder for sterile surgical implants. The implant holder is an ergonomically shaped body of deformable material having an implant-receiving cavity similar in size and shape to the implant. To remove the implant from the holder, the surgeon mates a sterile tool to the implant and gently pries the implant out of the holder by deforming the body. Preferably the tool used to pry the implant out of the body is an insertion tool mated to the implant which is also used to insert the implant in a patient. In this way the surgeon retrieves the implant from its container without touching the container and directly inserts the implant in the patient without risking contamination: sterility is maintained for both the surgeon and the implant. In a preferred embodiment, the implant holder is configured to hold two pedicle screws and their set-screws.

Abstract: A facet screw system and method includes an implant assembly having a screw with a removable head, a locking nut, and a collet. An insertion instrument is used to insert the screw, compress the facet joint, locks the implant, and breaks off the head of the screw providing a lower profile implant.

Abstract: The present disclosure relates to an anchor for fixating a tissue graft to bone. The anchor includes a through hole extending an entire length of the anchor and a polymer composition having shape memory qualities. Other anchors and methods for fixating a tissue graft to bone are also disclosed.

Abstract: A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

Abstract: Connector assemblies are provided to couple an elongate member extending along the spinal column to a bone engaging implant engaged to the spinal column. The connector assembly includes a coupler and a clamping member in the coupler that is movable to secure the implant between the clamping member and the coupler when the elongate member is secured in the coupler with an engaging member engaged to the coupler.

Abstract: A system, kit and method are provided for treatment of the spinal column, including a plurality of elongate support elements configured for placement across multiple levels of the spinal column wherein at least one of the elongate support elements is formed of a first material and at least one other of the elongate support elements is formed of a second material different from the first material, with the first material having a modulus of elasticity that is different from that of the second material. A plurality of fixation elements are provided which are configured to engage a number of the elongate support elements to the spinal column and which are formed of a third material that is bio-compatible with each of the first and second materials.

Abstract: An instrument is provided for use in orthopedic surgery for reduction of a connecting member such as a spinal rod toward an implant such as a bone screw. An embodiment of the instrument includes handle portions that are pivotable relative to each other and biased apart, and arm portions pivotable relative to each other and to the handle portions. Distal portions of the arm portions, which are offset from the arm portions, provide structure for engaging a connecting member and an implant. Squeezing the handle portions force the distal portions of the arm portions together, forcing together the connecting member and the implant. A toothed bar and pawl may be provided to retain the instrument in a squeezed state.

Abstract: An improved apparatus is provided to allow for an adjustable length tether for use in the spine and other parts of the body. The tether comprises an artificial strand with an eyelet formed in one end, the other end being looped through the eyelet. The other end is then secured with respect to the eyelet by a crimp, the excess length being cut off after the length of the tether has been given an appropriate tension. Alternatively, the eyelet end may be formed around a grommet. The crimp may be separate from the grommet or a part of the grommet. The mechanism by which the length is adjusted in some cases will take advantage of the shape memory properties of alloys such as nickel-titanium.
