An intervertebral implant includes a first endplate member and a second endplate member, and a distal wedge member and a proximal wedge member that couple the first and second endplate members together. The distal wedge member is configured to move in an expansion direction that causes the fusion cage to move from a contracted position to an expanded position.

Implant bending instruments disclosed herein can have a plurality of bending elements that can be symmetrically driven to bend or contour an implant, such as a spinal rod. A single actuator handle can be moved to drive a compound gear train and move the bending elements to intersect an implant-receiving channel and bend an implant received therein. Instruments of the present disclosure can have an increased mechanical advantage than conventional bending instruments thereby allowing for an increased amount of force to bend an implant. A locking pawl can selectively prevent counter rotation of the gear train such that the handle can be actuated a plurality of times to achieve a desired contour angle.

An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.

Expandable intervertebral fusion cage

An intervertebral fusion cage includes first and second endplate members, first and second ramp members, and an actuator. The first and second ramp members and first and second endplate members have complementary ramp surfaces that engage to expand the height of the fusion cage and to impart a lordotic profile to the fusion cage.
