    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 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 crown member disposed between the rod and the head of the bone screw. As the set screw is tightened into the receiver member, the set screw compresses the rod against the crown member, which presses the head of the bone screw into the tapered recess. In one embodiment, the head of the bone screw includes a flared edge that penetrates at least the crown member as the assembly is tightened.

    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： 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： An apparatus comprises a pair of bone attachment devices and a crosslink device for a spinal fixation system or other implant arrangement. The bone attachment devices include a head with socket to receive a spinal rod or other elongate element and the crosslink device includes a pair of bridging members each having an end section for connecting with the bone attachment devices. An interconnection device situated between the bridging members receives the bridging members and allows translational and rotational freedom therebetween while being operable to secure the bridging members in position relative to one another. A pair of engaging members are structured to engage the head of the respective bone attachment device and bear against the respective adjacent end of crosslink device to lock the crosslink and the bone attachment device in a rigid construct are also included.
