Abstract
Bone anchors, expandable intervertebral fusion devices, systems, instruments, and methods thereof. The anchor may include a spherical head and a curved blade extending therefrom. The spherical head may define a non-threaded opening including a vertical slot in communication with an internal spherical pocket, which interfaces with a corresponding non-threaded tip of a single anchor impactor instrument. The anchor may attach to the instrument via a quarter-turn connection, which provides navigation for straight and angled insertion and/or removal of the anchors.

- a lever for locking an anchor to the instrument, the lever being pivotably connected to the central shaft and the rear housing of the inner shaft by a lever pin, wherein the shuttle and washers are configured to slide axially over the central shaft when the lever is actuated and the central shaft is moved axially;
- and
- a ball detent within the rear housing of the inner shaft configured to engage with divots within the housing of the outer sleeve such that the inner shaft is held in one of two relative positions when rotated with respect to the outer sleeve.
