IPP-0050-US35 nextremity
The superior surface of the coupling member and an inferior surface of the collar form an engagement interface configured to constrain rotational movement of the inserter and the collar about the engagement axis. The engagement interface may include one or more protrusions on one of the superior surface of the coupling member and the inferior surface of the collar and one or more recesses on another one of the superior surface of the coupling member and the inferior surface of the collar. The engagement interface may include an interlocking coupling that may include a plurality of both teeth and valleys on each of the superior surface of the coupling member and the inferior surface of the collar, the teeth and valleys of each of the superior surface of the coupling member and the inferior surface of the collar intermesh when the coupling member and the collar abut.

In certain embodiments, one or more surfaces of the engagement member 1000 that contact one or more surfaces of the inserter 1008 and/or bone fastener may form an engagement interface. As used herein, an "interface" refers to an area, a boundary, or a place at which two separate and/or independent structures, members, apparatus, assemblies, components, and/or systems join, connect, are coupled, or meet and act on, or communicate, mechanically or electronically, with each other. In certain embodiments, "interface" may refer to a surface forming a common boundary of two bodies, spaces, structures, members, apparatus, assemblies, components, or phases. (search "interface" on Merriam-Webster.com. Merriam-Webster, 2021. Web. 15 Nov. 2021. Modified.) In certain embodiments, the term interface may be used with an adjective that identifies a type or function for the interface. For example, an engagement interface may refer to one or more structures that interact or connect to mechanically join or connect two separate structures, each connected to a side of the interface.

Figure 58 illustrates one example of a method 3000 for stabilizing a bone fastener that traverses a first bone portion and a second abutting bone portion. Referring to Figures 26 through 34, the method 3000 starts with a user, such as a surgeon, deploying 3002 a bone fastener within a first bone portion and a second bone portion. In one embodiment, the second bone portion abuts the first bone portion. The two bone portions may be parts of the same bone or may be parts of two different bones. In one embodiment, an implant may be used instead of one of the two bone portions. As illustrated in the figures and described above, deployment of the bone fastener may include a number of steps.

In certain embodiments, the pivot member 2024 includes a lock mechanism 2030. The lock mechanism 2030 enables a user to change the superior and/or inferior orientation to a desired superior and/or desired inferior orientation and then secure the pivot member 2024 to retain the desired orientation of the cross fixation insertion axis relative to the engagement axis 412. Of course, various forms of a lock mechanism 2030 may be used. In one example embodiment, the lock mechanism 2030 may be a knob with a threaded shaft that tightens against the pivot member 2024 to create a press-fit interface within the pivot member 2024 (and/or surfaces the pivot member 2024 and surfaces of the guide body 2014) and thereby maintain a current orientation.

Rotation of the pivot member 2024 may change the orientation of the fixation axis 420. In one embodiment, a user may use the pivot member 2024 to orient the cross fixation insertion axis 420 from a perpendicular orientation in relation to the engagement axis 412 to a superior orientation 2026. Alternatively, or in addition, in one embodiment, a user may use the pivot member 2024 to orient the cross fixation insertion axis 420 from a perpendicular orientation (or any superior or inferior orientation) in relation to the engagement axis 412 to an inferior orientation 2028. In this manner, a user can use the pivot member 2024 to pivot the cross fixation insertion axis 420 to any of an infinite number of superior and/or inferior orientations.

In the illustrated embodiment, the guide 2002 includes a guide member 2016 that may include a pivot member 2024. The pivot member 2024 may be connected or coupled to the guide body 2014 near the proximal end 2020. The pivot member 2024 enables a user to adjust an orientation of the fixation axis 420 (also referred to as a cross fixation insertion axis). In certain embodiments, the pivot member 2024 connects to a passage that accepts sleeves 2008. The pivot member 2024 may pivot or rotate about an axis which is transvers to a cross fixation insertion axis and an engagement axis.

In certain embodiments, the engagement member 2018 is configured to secure the guide member 2016 and/or the guide 2002 at any of the plurality of relative orientations. In one embodiment, the engagement member 2018 may secure the guide member 2016 at a desired relative orientation temporarily. For example, while a fixation member 812 is being deployed. In another embodiment, the engagement member 2018 may secure the guide member 2016 at a desired relative orientation permanently.

In certain embodiments, the relative orientations are orientations of the guide 2002 and/or its members in relation to the bone fastener 804. In one embodiment, the engagement member 2018 couples the guide 2002 to the bone fastener 804 directly. In another embodiment, the engagement member 2018 couples the guide 2002 to the bone fastener 804 indirectly by way of an inserter 806. In one embodiment, the engagement member 2018 may be coupled to the body 2014 near the distal end 2022. In the illustrated embodiment, the engagement member 2018 is coupled to the body 2014 at the distal end 2022.

In one embodiment, the engagement member 2018 couples the guide 2002 to the bone fastener 804. For example, in one embodiment the engagement member 2018 engages the bone fastener 804 such that the guide member 2016 is rotatable relative to the bone fastener 804 about an engagement axis 412 to a plurality of relative orientations. In another example, the engagement member 2018 engages the bone fastener 804 such that the guide 2002 is rotatable relative to the bone fastener 804 about an engagement axis 412 to a plurality of relative orientations.

In one embodiment, the guide member 2016 includes a passage through the guide member 2016 defining the cross fixation insertion axis 420 and one or more sleeves 2008a,b received in the passage in axial sliding relationship. In one embodiment, a passage of the guide member 2016 is sized to accept one or more sleeves 2008. Each sleeve 2008 may include an axial through passage having a cross-sectional diameter sized to permit the sleeve 2008 to slide axially within the passage. In the illustrated embodiment, the sleeves 2008a,b may each have different cross-sectional diameters that permit certain ones of the one or more sleeves 2008a,b to fit within each other in a nested configuration such that a longitudinal axis of the sleeves 2008a,b aligns with the fixation insertion axis 420.

The guide member 2016 may facilitate or enable preparation of a site for deployment of a fixation member 812. Alternatively, or in addition, the guide member 2016 may serve to guide deployment of a fixation member 812 to secure a bone fastener 804. In one embodiment, the guide member 2016 may be coupled to the body 2014 near the proximal end 2020. In the illustrated embodiment, the guide member 2016 is coupled to the body 2014 at the proximal end 2020.
