View Edit Delete	FLO-4	Rotation of the rotatable structures 112 may be limited by flat surfaces 122 manufactured into one or more partially circular recesses 120. Each of the flat surfaces 122 may engage a corresponding surface 124 associated with each of the arms 114 of the rotatable structure 112, thereby limiting the degree of rotation 504 and deployment of each of the rotatable structures 112 beyond the unlocked and locked orientations. The corresponding surface 124 may be flat but does not have to be.	75	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	FIG. 5 is a perspective top view of part of an implant assembly 100, according to one embodiment of the present disclosure. FIG. 5 illustrates examples of a rotation limiter 502a, b that includes corresponding surface 122, 124. In one embodiment, a rotation limiter 502 limits rotation of the rotatable structure 112 in either, or both directions, beyond the locked orientation and the unlocked orientation, while allowing rotation of the rotatable structure 112 between the locked orientation and the unlocked orientation. For example, rotation limiter 502a may limit rotation of rotatable structure 112 beyond a locked orientation. Similarly, rotation limiter 502b may limit rotation of rotatable structure 112 beyond an unlocked orientation.	74	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	As shown in FIG. 4B, each of the screws 302 may have a “toe in,” or angulation, within transverse plane (parallel to the page of FIG. 4B) relative to the screw 302 alongside it. This angulation may also be about 12 degrees. This angulation is merely exemplary; in some embodiments, it may range from about -15 degrees to about 45 degrees, or more particularly, from about 0 degrees to about 30 degrees, or yet more particularly, from about 5 degrees to about 20 degrees.	73	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	Each of the screws 302 may be pivotable, relative to the bone plate 108, such that the longitudinal axis 400 has a range of motion 420 in all directions of approximately 30 degrees. This range of motion is merely exemplary; in some embodiments, the range of motion may range from about 5 degrees to about 55 degrees, or more particularly, from about 15 degrees to about 45 degrees, or yet more particularly, from about 25 degrees to about 35 degrees.	72	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	FIGS. 4A and 4B depict the implant assembly 100 with four of the screws 302 of FIG. 3A, inserted in a neutral orientation such that each of the screws 302 is at the center of its range of motion relative to the bone plate 108. As shown in FIG. 4A, each of the screws 302 may have a longitudinal axis 400 that extends generally away from the bone plate 108. In the neutral orientation shown, the longitudinal axis 400 may be oriented at about 12 degrees, within a coronal plane (parallel to the page of FIG. 4A) from a normal vector 410 extending from the nearest surface of the bone plate 108. This orientation is merely exemplary; in some embodiments, it may range from about -15 degrees to about 45 degrees, or more particularly, from about 0 degrees to about 30 degrees, or yet more particularly, from about 5 degrees to about 20 degrees.	71	Added by DJM 5 2021	5/1/21, 12:00 AM
View Edit Delete	FLO-4	The semispherical seat 140 and semispherical rim 222 may cooperate to enable the screw 302 to pivot within the screw opening 106 within a range of motion. For example, the screw 302 may pivot within a range of motion ranging between approximately 45 degrees and approximately -45 degrees and the head feature 107 and lock feature 105 can engage and maintain engagement with each other with the rotatable structure 112 in a locked orientation. FIGs. 3B-3D illustrate examples of a screw 302 in three different orientations within the range of motion. FIG. 3B illustrates a screw 302 having its longitudinal axis oriented approximately 45 degrees from normal relative to the rotatable structure 112. FIG. 3C illustrates a screw 302 having its longitudinal axis oriented approximately 0 degrees from normal relative to the rotatable structure 112. FIG. 3D illustrates a screw 302 having its longitudinal axis oriented approximately -45 degrees from normal relative to the rotatable structure 112.	70	Added by DJM 5 2021	5/1/21, 12:00 AM

The implant assembly of claim 4, wherein the rotation limiter comprises a second flat surface of the bone plate and a second corresponding surface of the rotatable structure, the second flat surface and second corresponding surface configured to limit rotation of the rotatable structure beyond an unlocked orientation.	106	Added by DJM 5 2021	5/1/21, 12:00 AM

The implant assembly of claim 1, wherein the screw opening is configured to enable the screw to pivot within the screw opening within a range of motion ranging between approximately 45 degrees and approximately -45 degrees and wherein the head feature and lock feature are adapted to engage with each other with the screw pivoting within the range of motion and the rotatable structure in the locked orientation.	109	Added by DJM 5 2021	5/1/21, 12:00 AM

View Edit Delete	FLO-4	Thus, the counterclockwise (loosening) rotation of the screw 302 may be limited to, at maximum, an angular displacement equal to half the angular width of the sector occupied by a single raised ridge 216 of the head 210. This amount of counterclockwise rotation of the screw 302 may be sufficient to cause the raised ridges 216 to engage the radial grooves 116, regardless of whether the raised ridges 216 were aligned with the radial grooves 116 as loosening began to occur. Any additional counterclockwise rotation may be blocked, as it would urge clockwise rotation of the rotatable structure 112, which cannot occur due to abutment of the corresponding surface 124 of the arm 114 with the flat surface 122 of the partially circular recess 120, as described above.	69	Added by DJM 5 2021	5/1/21, 12:00 AM
