    摘要： Connectors are disclosed herein that can be used to attach a rod to a bone anchor assembly that is already occupied by a separate rod. Various ways of attaching the connector to the bone anchor assembly are disclosed, including arrangements in which the connector is locked to the bone anchor, arrangements in which the connector is constrained in one or more degrees of freedom relative to the bone anchor, arrangements in which the connector is adjustable in one or more degrees of freedom relative to the bone anchor, and arrangements that include a spherical articulation joint. In some embodiments, attachment of the connector to a bone anchor can be aided with the use of a positioner. The geometry of the connector can be selected to minimize the offset between a first rod received in the bone anchor assembly and a second rod received in the connector, for example using an angled or curved rod recess and/or a fastener, or set screw, that is offset from the center of the rod or angled relative to the bone anchor. The connector can be configured to align the first and second rods in a common coronal plane, or can be configured to position one rod more anterior or posterior than the other rod.

    摘要： A spinal correction system includes a tensioning member and a fulcrum tensioner device including a housing defining a chamber having a biasing member therein and a camming pin operatively coupled with the biasing member. The tensioning member is configured to be received in the biasing member and looped around the camming pin, such that a first end of the tensioning member is oriented in a first direction and a second end of the tensioning member is oriented in a second direction. The camming pin is transitionable between an extended position in which the biasing member applies tension to the tensioning member and a retracted position in which the biasing member is compressed to inhibit application of tension to the tensioning member.

    摘要： There is disclosed a tool for use with a hollow screw extender housing configured to be coupled to a screw assembly implanted into vertebrae. The tool comprises a static first shaft including a first proximal portion with a handle, a first curved mid-portion, and a first distal portion with a rod-receiving groove configured to receive an end of the spinal rod, a sliding second shaft including a second proximal portion coupled with a rotary mechanism, a second curved midportion, and a second distal portion, and a control mechanism on the handle arranged to actuate the rotary mechanism to translate the second shaft relative to the first shaft and engage the second distal portion with an end of a spinal rod received in the rod-receiving groove. There is also disclosed a method for grasping a spinal rod.

    摘要： Spine stabilization systems are disclosed. One spine stabilization system includes a bone screw assembly including a coupling member and a screw member received therein. The coupling member includes a pair of extension elements that form a pair of slots. The slots include bottom angled surfaces. An angled wedge member having a substantially horizontal bottom surface and an angled top surface is delivered on top of the screw member within the coupling member. A rod member can be delivered down the coupling member such that it rests on the slots and on top of the angled wedge member. A locking assembly comprising a cap member and set screw can be delivered down the coupling member to secure the rod member to the coupling member. The rod member and locking assembly components can be delivered through a single incision and at a same or similar angle as the screw member during surgery.
