    摘要: A tool assembly has a shaft with a sleeve slidable along it. A hexagonal drive post at the lower end of tile shaft is received in a hex socket at the upper end of a bone bolt secured in a patient's spine. A nut to secure a connector on the bolt, is temporarily stored on a short thread on the shaft near the lower end. The sleeve is slid down the shaft and a hex socket at tile lower end of tile sleeve is received on the nut. The sleeve is manually turned while a handle on a drive post at the top of the shaft prevents the shaft, and thereby the bolt, from turning. As the sleeve turns, the nut is turned off the short thread and down onto the bolt thread. A torque wrench coupled to a tool receiving surface at the top of the sleeve tightens the nut on the bolt to the specified torque while the handle on the top of the shaft prevents the bolt from turning.

    摘要: A surgical spinal fixation system includes a bone bolt having first end portions that are adapted to be surgically implanted into a patient's spine at first and second spaced apart positions and a central portion of the bone bolt defining a load transfer surface, the bone bolt having a second upper threaded sections for threadably receiving a nut at a shaped, countersunk interface. As an alternate embodiment, a bone screw provides an upper enlarged head with a lower coarsely threaded shank. A plate having upper and lower surfaces and outer opposed edges is provided with an elongated slot for accommodating a selected bone bolt or bone screw. The plate edges carry fine adjustments extending between the upper and lower surfaces of the plate and a load transfer washer interfaces the plate and the selected bone bolt or bone screw for distributing load (and reducing stress) from the bone bolt (or screw) to the plate.

    摘要: An orthopedic stabilization system of implants that includes a bone attachment means that provides poly-axial fixation of the system to the vertebrae, and a connector means that connects the bone attachment means to the spinal rod in a fashion that allows variable height adjustment of the spinal rod (dorsal in the case of posterior spinal pedicle fixation). The orthopedic stabilization system includes a locking means with a tightenable ball-joint arrangement that locks a post means to the bone attachment means in a desired relative spatial orientation. Several embodiments are disclosed, some using traditional mechanical locking means such as screw fasteners, taper-locking interfaces and collets. Embodiments are described that use the austenitic transformation of shape memory alloy (SMA) material to effect a locking of both the ball-joint arrangement and the connector means.

    摘要: A cable operated bone anchor compressor and a method for thoracoscopically compressing bone anchors are disclosed. In procedures in which bone anchors, such as bone screws, are fixed to bone tissue and such bone tissue is to be readjusted or realigned, the device of the present invention is thoracoscopically inserted. The device includes a cable to be placed in contact with one bone anchor, and an elongated member with a mating head to be placed against another bone anchor. When the cable is retracted, the bone anchors are compressed or pulled toward each other to realign, in a desired fashion, the bone tissue to which they are attached.
