View Edit Delete	IPP-0050-US35 nextremity	FIG. 56 is a diagram of an example of an engagement interface 1042 that may be used in various embodiments of the present disclosure. In one embodiment, the engagement interface 1042 may include an interlocking coupling of a plurality of teeth 1052 and a plurality of valleys 1054 on each of two surfaces, inferior surface 1056 and superior surface 1058. The plurality of teeth 1052 and the plurality of valleys 1054 intermesh when the inferior surface 1056 and the superior surface 1058 abut or come into contact with each other. The plurality of teeth 1052 and plurality of valleys 1054 are sized and shaped relative to each other to intermesh. The inferior surface 1056 and superior surface 1058 may have any variety or configuration of teeth relative to valleys. Furthermore, in certain embodiments, the inferior surface 1056 and superior surface 1058 may have a single tooth and/or valley respectively. In the illustrated embodiment, the plurality of teeth 1052 and plurality of valleys 1054 have a squared surface (cross section). Alternatively, or in addition, the plurality of teeth 1052 and plurality of valleys 1054 may have triangular cross section.	165	Added by DJM 12 2021	12/2/21, 12:00 AM

View Edit Delete	IPP-0050-US35 nextremity	In the illustrated embodiment, the shaft 1002 engages the bone fastener by way of threads 1014 that engage internal threads 1022 of a socket 1030 of the inserter 1008. Those of skill in the art will appreciate a variety of features, structures, and implementations may be used for the shaft 1002 to engage the bone fastener. For example, a pin extending laterally near the distal end 1012 may slide vertically along a channel along a wall of the socket 1030 and then seat within a horizontal section of the channel to compress the protrusion 1006 against at least a portion of the collar 1004. In certain embodiments, the inserter 1008 may include a coupling member 1032 near its proximal end. The coupling member 1032 may include the socket 1030.	160	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	Those of skill in the art will appreciate that the socket 1030 may have a variety of different forms, features, and configurations within the scope of the present disclosure. In one embodiment, the socket 1030 has a depth that accepts distal advancement of the shaft 1002 until the protrusion 1006 presses against the collar 1004. Alternatively, or in addition, the socket 1030 has a depth that accepts distal advancement of the shaft 1002 until the protrusion 1006 presses against the collar 1004 with a sufficient press fit to restrain rotation of the collar 1004 about the inserter 1008 and/or bone fastener.	159	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	In one embodiment, the shaft 1002 engages the bone fastener by way of threads 1014 that engage internal threads 1022 of a socket 1030 of the inserter 1008 which is secured to the bone fastener. In the illustrated embodiment, rotation of the shaft 1002 in a first direction may cause the threads 1014 to advance within the internal threads 1022 of the socket 1030 and thereby draw the protrusion 1006 closer to the collar 1004. As the threads 1014 advance, the protrusion 1006 presses against at least a portion of the collar 1004 (e.g., the inferior surface 1024 may press against the superior surface 1026). In certain embodiments, this pressure (or bias) is sufficient to retain the collar 1004 and a coupled guide in a first orientation about an engagement axis.	158	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	The protrusion 1006 may extend laterally from a cross sectional diameter of the shaft 1002. The protrusion 1006 may be coupled to the shaft 1002 near the proximal end 1010. In certain embodiments, the protrusion 1006 can be a variety of shapes including rectangular, cylindrical, or the like. The protrusion 1006 includes an inferior surface 1024 configured to contact a superior surface 1026 of the collar 1004.	157	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	The collar 1004 may be coupled with or integrated with the body of a guide and may include a through passage that axially aligns with the engagement axis. In certain embodiments, the collar 1004 may include a pin that extends distally from the collar 1004. In one embodiment, the through passage may include a proximal section 1016 and a distal section 1018. The proximal section 1016 and the distal section 1018 may be cylindrical and the proximal section 1016 may have a smaller diameter than the distal section 1018. In one embodiment, the proximal section 1016 may include internal threads 1020 configured to engage threads 1014 of the shaft 1002. Alternatively, or in addition, the proximal section 1016 may include internal threads 1020 configured to engage threads (not shown) near a proximal end 1010 of the shaft 1002. The internal threads 1020 may serve to secure the shaft 1002 and/or protrusion 1006 to the collar 1004 when a guide is not coupled to an inserter 1008 and/or bone fastener.	156	Added by DJM 12 2021	12/2/21, 12:00 AM
