Paragraph Number

140

The proximal end 858 of the inserter 806 includes a coupling member configured to rotationally couple to a guide 802 described herein. In the illustrative example of FIGS. 43-46, the coupling member includes a socket 880 extending distally into a superior surface 882 of the coupling member and a peripheral edge 884. In certain embodiments, the socket 880 may include internal threads 886. Alternatively, or in addition, the socket 880 may be a stepped cylindrical socket or cavity with a larger diameter proximal portion 888 and a smaller diameter, distal portion 890 that includes the internal threads 886. In one embodiment, the threads 834 of the lock mechanism 824 are configured to engage the internal threads 886 of the socket 880 and the socket 880 has a depth that permits distal advancement of the shaft 828 until the shoulder 830 presses against the superior surface 832 of the engagement member 818.
