Abstract
An insertion assembly may include a flexible tool and a DTS guide configured to engage an intervertebral spacer having a fastener channel oriented at a first angle. The DTS guide may include a DTS guide channel oriented at the first angle which may be aligned with the fastener channel. The flexible tool may include a flexible shaft and a working member disposed at a distal end of the flexible shaft. The working member may be received through the DTS guide channel at the first angle. At least a portion of the flexible shaft adjacent the DTS guide member may flex while the working member is received through the DTS guide channel, such that a distal portion of the flexible shaft may be at a greater absolute angle relative to a DTS guide shaft than a proximal portion of the flexible shaft.
