    摘要： A positionable clip is provided that is engageable on a spinal rod to capture a rod-borne component in a variable position on the rod. In one embodiment, the positionable clip includes a pair of clamping members, each including a pair of opposed arms configured for engaging the rod therebetween. A biasing hinge biases the arms together to grip the rod with sufficient force to maintain the position of the clip on the rod during manipulation of the rod. A bar connects the two clamping members to define a receiving space to receive a component that is disposed on the spinal rod. In one aspect, the bar includes a pressure surface such that a force applied to the pressure surface will cause the arms of the clamping members to displace apart to disengage from the spinal rod. The clip is configured so that this force can be applied by the component captured by the positional clip as the component is itself tightened onto the spinal rod.

    摘要： A new top-loading transverse connector of the present invention for bridging between longitudinal members of a spinal fixation system implant. The transverse connector is loaded and clamped to the longitudinal member from the top permitting easy access and adjustment and may clamp at the same location along the rod as a vertebral fixation element. The transverse connector comprises an elongate body and an engagement portion on each opposing end of the elongate body. The engagement portion includes downward legs each with a surface to engage the longitudinal member. The downward legs are displaced from each other to define a space therebetween. The engagement portion includes an upper surface defining an opening therethrough. The opening intersects the space defined between the downward legs. Together, the space and opening are configured to receive the clamp assembly carried on the longitudinal member. Another object of the invention, is to provide an improved system including the transverse connector. Another object of the invention is to provide a transverse connector that clamps to the longitudinal member at a variable angle. Another object of the invention is to provide a separate engagement portion which can be used with existing transverse connectors to permit clamping at the same site as vertebral fixation elements. Another object of the invention is to provide a way to adjust the length of the elongate body of the transverse connector.

    摘要： An iliac screw includes a smooth distal shank (35), a threaded proximal shank (37) and a proximal head portion (38). The smooth distal shank (35) is configured to penetrate the cancellous bone of the iliac wings, while the threaded shank (37) carries bone threads configured for engagement with the cortical or the cancellous bone. The head portion (38) is configured for engagement with an elongated fixation member, such as a spinal rod.

    摘要： A lateral connector assembly for connecting a bone engaging fastener to an elongated member, such as a spinal rod includes a lateral connector having an elongated opening for receiving a portion of the bone engaging fastener therethrough. The lateral connector includes a plate portion and an integral yoke portion, which yoke portion is attached to the elongated member by way of a clamp. The lateral connector assembly can include variable angle means between the clamp and the yoke portion of the lateral connector that permits rotation of the lateral connector about an axis projecting outward from the spinal rod. The plate portion and the yoke portion of the lateral connector are oriented at non-perpendicular angles, preferably an angle greater than 100 degrees. In a further embodiment the plate portion of the lateral connector is curved so that as the bone engaging fastener slides along the elongated opening, it assumes variable angular orientations relative to the lateral connector assembly and the elongated rod.

    摘要： An inflatable corpectomy device includes a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens.
