摘要： A transverse fixator assembly for spanning between a number of longitudinal members situated adjacent a patient's vertebrae and methods for fixation of the spine which allow variation of the distance between two or more vertebrae. The assembly includes a number of connectors configured to span the distance between and engage the longitudinal members. The connectors define a thru-hole for engaging a bone bolt which is engaged to a vertebra plus a number of spikes projecting from the connector. A locking mechanism is configured to prevent the bolt from rotating relative to the connector when the nut is being tightened. One or more of the connectors may be a dynamic connector which is slidably engaged to the longitudinal members to vary the distance between the vertebrae for compression or distraction.

摘要： A device for supporting weak bony structures comprises an elongated tubular body having first and second ends configured for contacting adjacent bony structures. A tubular body is formed by a plurality of intersecting elongate bars with a first group of bars having their longitudinal axes arranged perpendicular to the axis of the tubular body, and a second group of bars having their axes arranged at non-perpendicular angles relative to the body axis. The tubular body also includes a plurality of joints formed by the intersection of two perpendicular bars and four angled bars. The ends of the tubular body are defined only by the intersection of angled bars. The ends include a plurality of substantially flat end surfaces that have a surface area greater than the combined cross-sectional areas of the intersecting angled bars forming the joints at the end of the body. In a preferred embodiment, the end surfaces have an undercut between the surfaces and the intersecting angled bars. The tubular body can assume various shapes when viewed from an end, such as circular and non-circular shapes including at least one flat side.

摘要： In one embodiment, a spinal fixation assembly includes an elongated member, such as a spinal rod, configured for placement adjacent the spine and a bone engaging fastener, such as a bone screw having a lower portion configured for engaging a vertebra and a head that is at least partially spherical. The assembly further includes a receiver member defining a bore therethrough from a top end to a bottom end, a recess for receiving the head of the bone screwing fastener therein, and a lower opening at said bottom end of the receiver member through which the bone screw extends. The recess is configured to at permit pivoting of the bone screw within the receiver member until the head is fixed within the recess. The receiver member also includes a channel communicating with the bore and having an upper opening at the top end of the receiver member for insertion of the spinal rod into the channel. In one embodiment, two compression members are provided, each being formed of a temperature responsive material and having a first configuration at a first temperature and a different second configuration at a different second temperature in which the compression member contracts about a portion of the receiver member to thereby compress the receiver member about both the head of the bone screw within the recess and the spinal rod within the channel.

摘要： A multi-axial bone screw assembly includes a bone screw having a partially spherical head. The bone screw head is truncated at an upper surface in which a tool receiving recess is defined. The assembly includes a receiver member including a central bore that defines a tapered recess to receive a contracting collet carrying the head of the bone screw. The bore of the receiver member also defines a channel communicating with the recess and configured to receive a spinal rod therein. A portion of the channel is threaded to receive a set screw above the rod. The assembly also includes a contracting collet disposed between the rod and the head of the bone screw. The collet defines a partially spherical recess to receive the head of the bone screw, and includes deflectable fingers that substantially surround the screw head. As the set screw is tightened into the receiver member, the set screw compresses the rod against the collet, which presses the collet into the tapered recess of the receiver member, thereby deflecting the fingers of the collet against the bone screw head.

摘要： An internal anterior fixation system for treatment of vertebral burst fractures includes an elongated plate having longitudinal axis which includes integral superior, inferior and bridge portions. The superior and inferior portions are provided for fixation to corresponding vertebrae while the bridge portion spanning between the portions over the affected vertebra. The superior portion includes a pair of generally parallel elongated slots therethrough each having scallops on for receiving bone fixation screws or bolts. The inferior portion includes a pair of openings through which fixation screws or bolts extend. The slots in the superior portion allow for compression or distraction of the intermediate vertebral region. The openings in the inferior portion are oriented at an oblique angle relative to the axis of the plate to provide a quadrilateral fixation construct. The bridge portion has a width significantly less than the width of the superior and inferior fixation portions.

摘要： This invention relates to orthopedic implants and to methods of treating bone defects. More specifically, but not exclusively, the present invention is directed to non-metallic implants and to methods for intra-operative assembly and fixation of orthopedic implants to facilitate medical treatment. The non-metallic implant assembly can be secured to underlying tissue by a fastener, such as a bone screw, that is capable of swelling on contact with fluid in the underlying tissue. Alternatively, the non-metallic implant assembly can be assembled intra-operatively using a fastener that is adhesively bonded to a bone plate or the bone plate can be deformed using heat, force, or solvents to inhibit withdrawal of the fastener. In preferred embodiments, both the fastener and the bone plate are formed of biodegradable material.
