View Edit Delete	FLO-4	In FIG. 1A, the top two locking mechanisms 110 are shown in the unlocked orientation, while the bottom locking mechanism 110 is shown in the locked orientation. Each of the rotatable structures 112 may have a drive feature 118 or other torque-receiving feature that mates with a tool, such as driver (not shown) with a star-shaped head, to allow a surgeon to rotate the rotatable structure 112.	36	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	Referring now to FIGs. 1A and 1B, each of the locking mechanisms 110 may further have a detent mechanism that tends to urge its rotatable structure 112 to move fully into the unlocked orientation or the locked orientation. As used herein, a "detent" refers to an apparatus, instrument, structure, device, component, feature, system, mechanism, assembly, or module structured, organized, configured, designed, arranged, or engineered to resist or arrest the motion or rotation of a wheel, axle, spindle, or other structure. (Search 'detent' on Wikipedia.com June 22, 2020. Modified. Accessed March 19, 2021.) In certain embodiments, the detent continues to resist or arrest the motion or rotation while in an engaged configuration and permits the motion or rotation when in a disengaged configuration. Examples of a detent may include a single structure or a combination of structures cooperating to serve as a detent. Examples of a detent and/or detent assembly include but are not limited to a ratchet and pawl, a nub or bump and a recess, a recess and a raised or extending structure, a notch and a pin, a set of notches or recesses in a smooth structure and a set of corresponding nubs, latches, pins, spring loaded ball bearings, or the like. In one embodiment, a detent may comprise an ear of a rotatable structure and a groove, niche, notch, or carve-out of another structure.	46	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	Those of skill in the art will appreciate that the lock feature 105 and head feature 107 can be any structure on either the rotatable structure 112 and/or the head 210 configured and designed to engage with each other to accomplish the same result as the radial grooves 116 and raised ridges 216 described in the example embodiments herein. For example, in one embodiment, the lock feature 105 may be a bump or protuberance and the head feature 107 may be a depression or recess or hole such that these two features are configured to engage with each other to retain a screw 104 in the screw opening 106. In certain embodiments, the lock feature 105 and the head feature 107 may together be consider a type of detent mechanism.	45	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	The rotatable structure 112 is positioned on the bone plate 108 such that the lock feature 105 is disengaged from the head feature 107 when the rotatable structure 112 is rotated to an unlocked orientation. Accordingly, the screw 104 can rotate within the screw opening 106. When the rotatable structure 112 is rotated to a locked orientation the lock feature 105 engages the head feature 107 and in this manner restricts rotation of the screw 104 within the screw opening 106.	44	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	In one embodiment, the radial grooves 116 extend like radii of a circle that can be centered approximately where a screw 104 may seat within a screw opening 106 of the bone plate 108. In another embodiment, the lock feature 105 may include a single groove 116 positioned along the bottom surface 103 of the arm 114. Similarly, the head feature 107 may include a single raised ridge 216 configured to engage a corresponding single radial groove 116 of the lock feature 105.	43	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	In the illustrated embodiment, the lock feature 105 includes radial grooves 116. In embodiments for which the lock feature 105 includes radial grooves 116, the head feature 107 may include raised ridges 216 that correspond to the radial grooves 116. The raised ridges 216 of the head feature 107 may be shaped similarly to engage with the radial grooves 116.	42	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	The lock feature 105 and head feature 107 are configured such that once they engage with each other they cooperate to prevent both counterclockwise rotation and linear backing out of each of the screws 104, relative to the bones 102. Having the lock feature 105 on the bottom surface 103 enables the rotatable structure 112 to engage the lock feature 105 with the head feature 107 when the rotatable structure 112 is in the locked orientation. By rotating the rotatable structure 112 to the locked orientation the lock feature 105 engages with the head feature 107 and this restricts rotation of a screw 104 within a screw opening 106.	41	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	In one embodiment, the lock feature 105 and head feature 107 include structures that cooperate to selectively engage and lock two structure relative to each other. For example, a lock feature 105 may include one or more radial grooves 116. And a head feature 107 may include one or more raised ridges 216 adapted to engage a corresponding one or more radial grooves 116 of the lock feature 105. Of course, in another embodiment, the lock feature 105 may include one or more raised ridges 216 and the head feature 107 may include a corresponding one or more radial grooves 116.	40	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	The bottom surface 103 includes a lock feature 105 configured to cooperate with a head feature 107 (See FIG. 1A, 2A) of a screw 104. As used herein, "feature" refers to a distinctive attribute or aspect of something. (Search "feature" on google.com. copyright Oxford Languages, 2021. Web. 20 Apr. 2021.) A feature may include a modifier that identifies a particular function or operation and/or a particular structure relating to the feature. For example, a lock feature 105 refers to a feature that relates to, or is involved in, a locking function. Similarly, head feature 107 refers to a feature that is associated with a particular part, such as a head of a screw 104.	39	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	FIG. 1B is a bottom view of a rotatable structure 112, according to one embodiment of the present disclosure. The rotatable structure 112 may include a top surface 101 (See FIG. 1A) and a bottom surface 103. The bottom surface 103 may face the bone plate 108.	38	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	Optionally, each of the rotatable structures 112 may include a pair of opposed arms 114, with each arm blocking withdrawal of a respective screw 104 when the rotatable structure 112 is in the locked orientation. In some embodiments, a locking mechanism may be shaped to block withdrawal of one, three, or more screws rather than two. In such configurations (not shown), the locking mechanisms may have one, three, or more arms, with one arm for each screw 104 the locking mechanism is to retain. In some embodiments, the arms 114 may not only interfere with linear motion of the screws 104 out of the bones 102 but may also interfere with rotation of the screws 104 in a direction that would loosen their engagement with the bones 102 (for example, counterclockwise in the view of FIG. 1A).	37	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	Specifically, each of the rotatable structures 112 may sit in a recess 120 manufactured into an outer surface of the bone plate 108. In one embodiment, the recess 120 may be a partially circular recess 120. Further, each of the partially circular recesses 120 may define a niche 130 that can receive either of two ears 132 protruding from a central hub 134 of the rotatable structure 112. One of the ears 132 may reside in the niche 130 in the locked orientation, and the other may reside in the niche 130 in the unlocked orientation. As the rotatable structure 112 approaches the locked orientation or the unlocked orientation, the corresponding ear 132 may slide into the niche 130, causing the rotatable structure 112 to “snap” into the locked configuration or the unlocked configuration. The engagement of an ear 132 within the niche 130 can provide either an audible “snap” as the two parts engage and/or the engaging ear 132 and niche 130 can provide a tactile movement that an operator can feel in a driver (not shown) that engages the drive feature 118 of the rotatable structure 112 to move the rotatable structure 112 into a locked orientation. Similarly, engagement of an ear 132 within the niche 130 can provide a tactile feedback to an operator using the driver to move the rotatable structure 112 into an unlocked orientation	47	Added by DJM 5 2021	5/1/21, 12:00 AM
