摘要: A modular bone fastener system for use with a longitudinal member, such as a plate, having a fastener with a threaded lower potion for engaging a spinal element and an upper portion adapted to receive a headpiece. The headpiece is adapted to mate with the upper portion of the fastener and to engage a longitudinal member. A plurality of headpieces having angulated projections, lateral sections, and angulated lateral sections, all of which are adapted to engage a longitudinal member and overcome angular and translational misalignment of the fastener, may also be provided. The headpieces of some connectors are configured to permit angulation of a bore fastener relative to the connector.

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.

摘要: A method and an assembly for reducing a displaced vertebra and connecting the displaced vertebra to a spinal implant rod. The assembly has a reduction bolt with machine threads on one end and coarse threads on the other. A connection unit attaches the spinal rod to the reduction bolt, and until it is tightened, the connection unit allows the reduction bolt to slide within the connection unit. The connection unit includes a washer that rides against the side of the reduction bolt, and a nut is threaded onto the machine threads of the reduction bolt over a collar. The collar open is open at both ends and is of a size to readily slide over the reduction bolt. The posterior face of the collar has a notch to accept that portion of the lateral side of the washer as it presses against the reduction bolt. The notch is part of the open end of the collar into which is slide over the reduction bolt and down onto the connection unit. Arranged in this fashion, the nut can be tightened against the collar to move the displaced vertebra toward the longitudinal member. The third clamp can be tightened to secure the reduction bolt to the longitudinal member, and then the nut and the collar can be removed from the patient without the vertebra moving away from the longitudinal member.

摘要: Forceps are provided with a bifurcated gripping nose on one end adapted to pivotally engage an implant while a rod passes between the branches of the bifurcated gripping nose. The forceps further define a fulcrum adjacent the gripping nose. The pivotally engaging gripping nose and included fulcrum permit a surgeon to urge the rod into an opening in the implant with a single instrument while securely gripping the implant. With the implant pivotally engaged by the gripping nose, movement of the forceps towards the rod brings the fulcrum into contact with the rod and further movement urges the rod into an opening in the implant. In an alternative form, the gripping nose is laterally offset to urge a laterally offset rod into alignment with the implant upon rotation of the forceps.

摘要: A spinal fixation system includes a relatively rigid fixation plate which is engaged to a plurality of vertebrae by bone screws or bolts. The plate includes a longitudinal slot defined therethrough with an arrangement of scallops formed at the edge of the slot on the upper and lower surfaces of the plate. The scallop arrangement includes a first set of scallops formed at one spherical radius and a second set of scallops nested within the first that are formed at a smaller radius. Thus, the fixation plate can accommodate bone screws or bolts, or other bone engagement or load transmitting components having curved engagement surfaces of various diameters and providing varying degrees of rigidity. In another feature of the invention, a C-shaped ring is provided which encircles the plate to entrap the side walls of the plate, thereby restricting the plate walls from spreading as the bone screws or bolts are tightened onto the plate. The side walls of the plate and the inner walls of the C-shaped ring are correspondingly curved to retain the ring on the plate.

摘要: One external fixation frame, for immobilizing bone segments adjacent a fracture or joint, includes a fixation block with a pair of arms extending from the block across the fracture or joint. Another embodiment has but a single arm while a third embodiment includes one or two arms projecting from each end of the block. A ball and socket joint connects each arm to the block for universal movement thereabout. Length adjustment is accomplished via a turnbuckle formed in each arm. The outer end of each arm includes a slot for connecting to pins inserted in the respective bone segments. Set screws are provided for tightening the ball and socket joints and for holding the pins in the slots.

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.
