Abstract
An intervertebral spacer may include a fastener channel configured to receive a fastener, a locking member channel, and a locking member. The locking member channel may include an inner wall and one or more inner wall engagement features. The locking member may include an anti-backout member, a collet retainable within the locking member channel, and one or more collet engagement features. The locking member may be rotatable within the locking member channel between an unlocked position and a locked position. The one or more collet engagement features may engage the one or more inner wall engagement features in order to retain the locking member in either the unlocked position or the locked position, such that the anti-backout member may selectively obstruct the fastener channel and prevent the fastener from backing out of the fastener channel.
