[ 9. A method of performing surgery, comprising:
inserting an expandable intervertebral implant into an intervertebral space between an upper vertebral body and a lower vertebral body, the expandable intervertebral implant including:
an upper body and a lower body articulatable relative to each other in a first direction away from one another and a second direction towards one another, the upper and lower bodies being articulatable to a plurality of articulated arrangements in each of which the upper and lower bodies are positioned to define a different respective angle therebetween; and
a locking mechanism movable independently of articulating the upper and lower bodies relative to each other between an unlocked configuration and a locked configuration, wherein, when the locking mechanism is in the locked configuration, the locking mechanism locks the positions of the upper and lower bodies relative to each other in any one of the plurality of articulated arrangements with the respective angle therebetween, wherein, when the locking mechanism is in the unlocked configuration, the upper body and lower body are articulatable freely in both the first and second directions, and wherein a portion of the locking mechanism translates along a linear axis without rotating when the locking mechanism moves between the unlocked and locked configurations. ]
