Abstract (en)
[origin: WO2022192512A1] A system for treating a subject's spine can include an intervertebral spacer. The intervertebral spacer can be movable between unexpanded and expanded configurations. A locking member can have a threaded distal region configured to threadably engage the intervertebral spacer, and a proximal drive. A drive instrument assembly can include a retention mechanism detachably couplable to the locking member. The retention mechanism can include a socket configured to receive the drive head to rotationally fix the drive instrument to the locking member, and a spring element biased outwardly to releasably hold the drive head in the socket when the spring element extends into the drive head. The drive instrument assembly can be configured to rotate the locking member to move the intervertebral spacer from the unexpanded configuration to the expanded configuration.
