    摘要： A spinal fixation assembly is provided that includes a bone engaging fastener and an elongated member, such as a spinal rod. The fixation assembly is a multi-axial assembly that permits fixation of the bone engaging fastener to the spinal rod at any of a continuous range of angles relative to the rod in three-dimensional space. The fixation assembly includes a receiver member having a bore therethrough, the walls of which are tapered near the bottom, and a channel communicating with the bore and having an upper opening at the top of the receiver member for insertion of a spinal rod. Also included are an outer wedge member and an inner wedge member, both of which have generally the shape of a washer and a bore therethrough. In each wedge member, the respective bore is not parallel to the central axis of the respective wedge member. Additionally, the outside surfaces of the wedge members may be tapered, and the respective bores may be tapered, so as to self-lock when seated and tightened. The bone engaging fastener fits within the bore of the inner wedge member, which in turn fits within the bore of the outer wedge member, which in turn fits within the tapered sides of the receiver member. When the desired position of the bone engaging fastener in three-dimensional space is attained, the components are seated to achieve a tight friction fit.

    摘要： The treatment and correction of spinal deformities, such as scoliosis, is accomplished without the need for fusion of the intervertebral disc space. A surgical technique is provided in which opening and closing osteotomies are created in the affected vertebrae. Correction devices are provided which hold the osteotomies in either their closed or open orientations. The correction devices include staples holding the vertebral body on opposite sides of the body to retain the osteotomies in their desired orientation. In the opening osteotomies, the correction devices include a wedge member that is disposed within the opened wedge osteotomy and in contact with the vertebral body. The correction devices also include connection members which can be used to engage the devices to an elongated member spanning the spine, such as a spinal rod. Once bone union has occurred in the instrumented vertebrae, the spinal rod can be disconnected from the correction devices and removed from the patient. In another aspect of the invention, curvature deformities in two planes can be corrected using the same techniques and devices.

    摘要： A multi-axial bone engaging fastener 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. In another embodiment, the bone screw head includes a plurality of circumferential ridges configured to bite into the crown member. In a further aspect, the crown member is threaded to be inserted into the receiver member by threading through the threaded portion of the receiver member.

    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.

    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.
