  • Publication number: 20240398580
    Abstract: 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.
