    摘要： An instrument for tensioning a flexible elongate member in a surgical procedure includes a tensioning mechanism engageable to a portion of the flexible elongate member and operable to apply a tensioning force to the elongate member. The instrument includes a distal end portion at a distal end of the tensioning mechanism that is adapted to allow orientation of the elongate member in a first direction for implantation and to allow the instrument to extend transversely to the implantation orientation during application of a tensioning force. The distal end portion can also include a receptacle to receive a structure at the surgical site to facilitate positioning of the distal end portion at the desired location.

    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.

    摘要： A multi-piece vertebral attachment device with a first member, one or more second members, and optionally, a removable plug. The first member may have a fixed, threaded exterior surface to engage a vertebral member. The first member may further include a hollow, threaded interior. The hollow interior may be positioned inside the threaded exterior surface and at least partly positioned within the vertebral member when the first member is inserted in the vertebral member. The second member may have an outer diameter sized to fit within the hollow interior of the first member. A spinal implant device may be coupled to the second member. The second member may be installed during a separate surgical procedure from that of the first. The removable plug may be installed in the first member until the second member is installed. Revision may be performed by removing the second member and inserting a third member.

    摘要： Elongated connecting elements include bodies having anisotropic cross-sectional shapes defining a first moment of inertia about a first bending axis and a second moment of inertia about a second bending axis that is transverse to the first bending axis. The connecting elements are positioned along one or more spinal motion segments and engaged to vertebrae with anchors with the first and second bending axes in the desired orientation relative to the spinal motion segments.

    摘要： A vertebral rod has an elongated body extending along a longitudinal axis. The rod also includes a cavity extending the length of the body. Either the body or the cavity may have an asymmetrical shape about a centroid in a plane perpendicular to the longitudinal axis. Alternatively, both may have the symmetrical shape about the centroid. The body of the rod may be bounded by an exterior surface and the cavity. The body has a first bending axis that is perpendicular to longitudinal axis. The body also has a second bending axis that is perpendicular to the longitudinal axis and to the first bending axis. The body of the rod may be distributed asymmetrically about the first and second bending axes. Also, the rod may have a different bending stiffness about the first and second bending axes.
