    摘要： The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. The cages may contain an articulating mechanism to allow expansion and angular adjustment, and enable upper and lower plate components to glide smoothly relative to one another. The cages may have a first, insertion configuration characterized by a reduced size at each of their insertion ends to facilitate insertion through a narrow access passage and into the intervertebral space. In their second, expanded configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. The intervertebral cages are able to adjust the angle of lordosis, and can accommodate larger lodortic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

    摘要： An intervertebral implant for spondylolisthesis correction includes a superior side with serrations angled superiorly and toward the implant insertion direction, an inferior side with serrations angled inferiorly and opposite the implant insertion direction, and an instrument connection feature. An instrument for connection to the implant includes an implant connection feature movable between unlocked and locked states, and a friction-reducing feature movable between disengaged and engaged states. The instrument has a first state, in which the implant connection feature is in the unlocked state and the friction-reducing feature is in the disengaged state; a second state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the engaged state; and a third state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the disengaged state. Methods of apparatus assembly and surgery are disclosed.

    摘要： An expandable bi-dimensional intervertebral implant for an intervertebral fusion is provided. The implant includes a first hinge arm, a second hinge arm connected to the first hinge arm, and a translation member movable relative to the first hinge arm and the second hinge arm between an initial position and an engaged position. The second hinge arm is movable between a primary position and a secondary position relative to the first hinge arm. In the engaged position, the translation member biases the first hinge arm to move from a first position to a second position and biases the second hinge arm to move between a first position and a second position.

    摘要： An implant includes a first support, a second support rotatably coupled to the first support along a distal end of the implant, and a control assembly configured to move the implant between at least a first, collapsed orientation and a second, expanded orientation, the control assembly includes a control driver coupled to the first support and comprising a head and a shaft, the control driver configured to control relative movement between the first support and the second support, a control member configured to move along the shaft of the control driver, and a first linkage hingedly coupled to the control member and the second support, wherein movement of the control member causes the first support to move relative to the second support.

    摘要： Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

    摘要： A spinal implant apparatus that is an expandable spacer including features to minimize or eliminate spacer cant or offset during and after completing the expansion process. The spacer includes a top component, a base component in engagement with the top component, and an expansion mechanism arranged to change the top component's position with respect to the base component. The mechanism for causing expansion may be a screw, a cam, a wedge or other form of distracting device. In one embodiment, the expandable spacer includes a base component with a set of towers and a top component with a set of corresponding silos, where the towers and silos are configured to minimize or eliminate tilt of the top component as it extends upwardly from the base component.
