    摘要: A spinal fixation system comprises an elongated fixation plate (13) having an elongated slot (21) with a number of concave depressions (28,25) formed at the top and bottom surfaces (19,17) of the plate. The system further includes a pedicle screw (40) and a nut (32) for load transmission between a vertebra and the plate. The pedicle screw includes a threaded nut engaging portion (42), a threaded bone engaging portion (44) and an intermediate portion (46) therebetween which has rigid upper and lower arcuate surfaces (47) that are complementary to the concave depressions in the plate. The nut also includes a rigid lower arcuate surface (36) which is complementary to the upper concave depressions of the plate. In one assembled configuration the plate is clamped between the upper arcuate surface of the pedicle screw and the nut. In an alternative embodiment of the pedicle screw (70), the intermediate portion has an upper and lower arcuate surface (79,77) of different spherical radii of curvature.

    摘要: A a spinal fixation system comprises an elongated fixation plate having a bottom side for facing the vertebrae, an opposite top side extending generally parallel to the bottom side, and an elongated slot defined therethrough which extends substantially along the length of the plate. The slot has a lower edge at the intersection of the slot and the bottom surface and an upper edge at the intersection of the slot and the top surface with a number of concave depressions formed at each edge. In one embodiment, the concave depressions at the lower and upper edges of the slot form comparable scalloped surfaces. In another embodiment, the lower edge of the slot forms a single concave surface extending around the entire perimeter of the lower edge of the slot. The system further includes a pedicle screw and a nut for load transmission between the vertebrae and the fixation plate. The pedicle screw includes a threaded nut engaging portion, a threaded bone engaging portion and an intermediate portion therebetween. The intermediate portion has a rigid upper arcuate surface facing toward the nut engaging portion which is substantially complementary to the concave depressions in lower edge of the slot. The nut includes a threaded head portion for engaging the nut engagement portion of the pedicle screw, and a rigid lower arcuate surface which is substantially complementary to the concave depressions at the upper edge of the slot. In the assembled configuration of the spinal fixation system, the fixation plate is supported by the upper arcuate surface of the pedicle screw and is clamped between the pedicle screw and the nut. The concave depressions and the upper and lower arcuate surfaces coact to permit angulation of the pedicle screw relative to the elongated plate while maintaining load transmitting contact over a wide range of angles of the pedicle screw relative to the fixation plate.

    摘要: Skeletal stabilization systems include a base, a longitudinal member, and a retaining member. The base includes an engagement surface with a surface area that is positionable in contact with a bone to atraumatically or traumatically engage the base to the bone. The retaining member engages the base to retain the longitudinal member relative to the base so that the longitudinal member can provide a desired stabilization effect to one or more adjacent bony portions.

    摘要: A orthopedic fixation system comprising a plate with an outwardly-extending member. A saddle may be mounted on the member and includes spaced-apart arms that form a channel to receive a rod. An engagement member may be mounted within the saddle to prevent escape of the rod. In one embodiment, the engagement member is attached to the saddle to apply a downward force on the rod and an upward force on the saddle to lift the saddle relative to the plate. A method of attaching an orthopedic rod is also included. In one embodiment, a rod is positioned within a channel in the saddle and a downward force is applied against the anchor which results in an upward force on the saddle to lift the saddle relative to the anchor.

    摘要: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together. The cylindrical member can be bent along multiple axes. The occipital plate secures the rods to the occipital bone of the skull. The occipital plate has a cross-shaped plate with a plurality of apertures defined in the plate and at least one saddle member coupled to the plate. Alternatively, the occipital rod can be secured to the occipital bone.

    摘要: A cable used in spinal surgery has one crimp of a two crimp assembly crimped to one end of it. The second crimp has a ball held in a socket of the first crimp. The other end of the cable is passed around the bone or bones and any necessary orthopedic spinal device and it is then passed through an aperture in the second crimp. The cable is then tensioned by application thereto of a tensioning tool with the tool applied to the cable and to an abutment face of the second crimp, whereupon the cable is tensioned, with the ball and socket arrangement enabling swiveling of the crimps with respect to each other, thus minimizing sharp bends in the cable. Then the second crimp portion receiving the cable portion in the aperture adjacent the tensioning tool is crimped onto that cable portion to complete the attachment. Then the tensioning tool is removed, and the free end of the cable is cut off at the abutment surface. Other embodiments include a bar with two swivel crimps captured therein and a cable passing from one of the crimps around some spinal processes and back into the other of the crimps. A further embodiment includes a bar with sets of concave seats for engaging but not capturing swivel crimps. A further embodiment includes a base factory-crimped to one end of the cable, and concave seats on opposite sides of the base for swivel mounting but not capturing a ball crimped to another portion of the cable.

    摘要: A double-apertured L-shaped crimp is crimped to one end of a cable. The other end of the cable is passed around the bone and an orthopedic device to be attached to the bone, and it is then passed through the other aperture in the crimp. A releasable, lever-operated cable clamp is installed on the cable, followed by a tensioning tool. The tensioning tool applies a pre-positioning tension on the cable. The cable clamp is clamped to the cable to hold the tension. The tool is removed for use on another cable. When ready for final tensioning, the tensioning tool is re-installed, adjusted to the desired final tension, the crimp swaged onto the cable to hold the final tension, the cable clamp unclamped, the tensioning tool released and removed with the cable clamp, and the cable is cut off at the crimp.
