Abstract
Bone implants and stabilizing rod coupling assemblies to secure a stabilizing rod relative to the bone implant. Bone implants may include a radially recessed collet receiving region that includes a proximal end with an undercut ledge configuration that is sized and configured to interface with and couple to a collet of a tulip assembly.

A method of securing a bone implant to a rod, the method comprising:
- advancing a bone implant into bone with a bone implant delivery tool that is coupled to a proximal region of the bone implant;
- disengaging the bone implant delivery tool from the bone implant and removing the bone implant delivery tool;
- coupling a guide rod to the proximal region of the bone implant such that the guide rod extends proximally from the bone implant;
- coupling a tulip assembly delivery tool to a tulip assembly, the tulip assembly including a tulip, a collet at least partially disposed within the tulip, and a saddle within the tulip and at least partially proximal to the collet;
- using the tulip assembly delivery tool to advance the tulip assembly over the guide rod;
- advancing the collet against a proximal end of the bone implant proximal region and causing a distal end of the collet to expand as it is advanced over the bone implant proximal region;
- continuing to advance the collet over the bone implant proximal region until a radially inward protrusion of the collect moves radially inward into a recessed region of the bone implant, the recessed region of the bone implant having a proximal end with an undercut ledge configuration.

- and
- positioning a rod through a side opening in the tulip and screwing a set screw into the tulip until the set screw applies a stabilizing force on the rod and until the tulip is secured in place relative to the bone implant.
