View Edit Delete	VIL-12	FIG. 6 illustrates an implant 600 with a different configuration from the implant 500. Patients may have a variety of conditions within the MTP joint 250 that can be addressed with embodiments of the present disclosure. In certain instances, a patient may present with an OCL that is smaller than the natural articular surface 260. In other instances, the condition of the natural articular surface 260 may be such that the whole natural articular surface 260 needs to be resurfaced. The implant 600 can be used in these instances. Generally, the implant 600 may be sized and configured to cover and/or replace a natural articular surface 260 of a bone.	91	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	FIG. 6 is a perspective side view of a system deployed on a foot joint according to another embodiment of the present disclosure. FIG. 6 illustrates an MTP joint 250 between a first proximal phalanx 130 and a first metatarsal 110. In one embodiment, the first metatarsal 110 may include a bone tunnel 340. FIG. 6 includes similar components, parts, devices, apparatus, features, and aspects as those disclosed and described in relation to FIG. 3, however the difference in FIG. 6 is that the system uses an alternative embodiment of the implant.	90	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The implant 540 may be used in a variety of ways and can offer a variety of advantages for a particular use. For example, in one embodiment, the proximal body 560 and the distal body 550 may be made from different materials, each having different wear characteristics, strength, elasticity, and/or durability. In one embodiment, the proximal body 560 may be made from a metal or a metal alloy and the distal body 550 may be made from a polymer, a Synthetic polyvinyl alcohol (PVA) hydrogel, a biomaterial, a biocompatible polymer such as PolyEther Ether Ketone (PEEK) or a polylactide polymer (e.g. PLLA), and/or others. The difference in attributes between the distal body 550 and the proximal body 560 may provide advantages in terms of cost, durability, wear, and/or the like.	89	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In one embodiment, the bone anchor 820 may sit within a bone tunnel of a bone of the patient. The bone anchor 820 may sit within a proximal opening of the bone tunnel. In one embodiment, the body 822 is a cylindrical body that includes a passage or opening 826 that extends from a proximal end 828 to a distal end 830.	98	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	FIG. 5E is a perspective exploded view of an implant 540 according to another embodiment of the present disclosure. FIG. 5E includes similar components, parts, devices, apparatus, features, and aspects as those disclosed and described in relation to FIGS. 5A-5D, however the difference in FIG. 5E is that the body includes a distal body 550 and a proximal body 560. The distal body 550 may include a convex distal surface similar, in certain embodiments, to the joint-facing articular surface 512 of implant 500. The proximal body 560 may include a semispherical proximal surface similar, in certain embodiments, to the posterior surface 514 of implant 500. Of course, the surfaces of the distal body 550 and proximal body 560 may be very different from those of other example embodiments included herein.	87	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In the illustrated embodiment, the connector 530 includes cut outs 532a,b and an opening 534. The cut outs 532a,b may facilitate aligning a coupler (e.g., a transosseous coupler 320) with a center of the implant 500. Those of skill in the art will recognize that the cut outs 532a,b may be optional and may or may not be included in an embodiment. The opening 534 may engage with the coupler to couple the implant 500 and the coupler. In the illustrated embodiment, the opening 534 extends from one cut out 532a to an opposite cut out 532b. In one embodiment, the coupler may be a tether and the connector 530 engages with the tether and secures the implant 500 to the tether. For example, one end of a tether may be passed through opening 534 and the tether may be tied into a knot to secure the tether to the implant 500.	86	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	An example of a fastener system is a rod or shaft having external threads and an opening or bore within another structure having corresponding internal threads configured to engage the external threads of the rod or shaft. In certain embodiments, the term fastener may be used with an adjective that identifies an object or structure that the fastener may be particularly configured, designed, or engineered to engage, connect to, join, contact, or couple together with one or more other structures of the same or different types. For example, a "bone fastener" may refer to an apparatus for joining or connecting one or more bones, one or more bone portions, soft tissue and a bone or bone portion, hard tissue and a bone or bone portion, an apparatus and a bone or portion of bone, or the like.	85	Added by DJM 2 2022	2/5/22, 12:00 AM

Other examples of fasteners include, but are not limited to wires, Kirschner wires (K-wire), anchors, bone anchors, plates, bone plates, intramedullary nails or rods or pins, implants, sutures, soft sutures, soft anchors, tethers, interbody cages, fusion cages, and the like. In certain embodiments, the term fastener may refer to a fastener system that includes two or more structures configured to combine to serve as a fastener.	84	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In certain embodiments, the implant 500 may include a connector 530. "Connector" refers to any structure configured, engineered, designed, adapted, and/or arranged to connect one structure, component, element, or apparatus to another structure, component, element, or apparatus. A connector can be rigid, pliable, elastic, flexible, and/or semiflexible. Examples of a connector include but are not limited any fastener. As used herein, a "fastener" or "fastener system" refers to any structure configured, designed, or engineered to join two structures. Fasteners may be made of a variety of materials including metal, plastic, composite materials, metal alloys, plastic composites, and the like.	83	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The edge 520 is a structure between the joint-facing articular surface 512 and the posterior surface 514. As used herein, “edge” refers to a structure, boundary, or line where an object, surface, or area begins or ends. An edge can also refer to a boundary or perimeter between two structures, objects, or surfaces. An edge can also refer to a narrow part adjacent to a border. (search "edge" on Merriam-Webster.com. Merriam-Webster, 2021. Web. 03 Aug. 2021. Modified.) In certain embodiments, an edge can be a one dimensional or a two dimensional structure that joins two adjacent structures or surfaces. Furthermore, an edge may be at a perimeter of an object or within a perimeter or boundary of an object. In the illustrated embodiment, the edge 520 may have a circular cross-section.	82	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In one embodiment, the posterior surface 514 is shaped to engage with a distal articular surface (e.g., natural articular surface 260) of a bone. The posterior surface 514 may be shaped to engage with the distal articular surface by way of a bone pocket formed within the distal articular surface. In one example, the bone pocket may be concave shaped and the posterior surface 514 may be convex shaped to match or substantially match the concave shape of the bone pocket. A concave bone pocket and convex posterior surface 514 can enable the body 510 to seat within the bone pocket when deployed.	81	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	The joint-facing articular surface 512 can have a variety of shapes and configurations. In one embodiment, the joint-facing articular surface 512 may be generally flat. In another embodiment, the joint-facing articular surface 512 may have a contour configured to facilitate articulation with a natural articular surface 270 of an adjacent bone.	80	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In one embodiment, the bone tunnel 862 is cylindrical and the bone pocket 864 is semispherical, half spherical, circular, or the like. In one embodiment, the bone pocket 864 may be cylindrical. The bone pocket 864 may be formed in the natural articular surface 260 / distal articular surface 860 using a surgical reamer with a semispherical bit. The size and shape of the bone pocket 864 can vary based on similar characteristics to those for the bone tunnel 862. The bone pocket 864 can have a diameter (e.g., a maximum diameter) that is slightly larger than the diameter of an implant 500 or arthroplasty implant 810. A spherical bone tunnel 862 may not have a minimum diameter.	107	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	Advantageously, certain embodiments of the present disclosure provide fixation of the articular implant 900 within the joint as the bones and joint heal from a procedure. In certain embodiments, the fixation is temporary and/or adjunctive (or supplemental) to a permanent fixation as the bone fuses with the articular implant 900 as part of the healing process.	116	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	Together the articular implant 900, tether 840, and bone anchor 820 cooperate to replace at least a portion of the distal articular surface 860 (e.g., a natural articular surface 260). The articular implant 900 can serve as a spacer within a joint (e.g., an MTP joint 250). "Spacer" refers to a mechanical device, apparatus, member, object, body, component, or structure, that is organized, configured, designed, arranged, or engineered to maintain a separation between two adjacent objects, surfaces, or structures. The articular implant 900 maintains separation between the distal articular surface 860 and the articular surface of an adjacent phalanx bone (e.g., first proximal phalanx 130).	115	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	In addition, the surgeon has coupled the tether 840 to the bone anchor 820 such that the bone pocket 864 retains the articular implant 900 in place during osseointegration of the articular implant 900 into the metatarsal bone 816. In one embodiment, the surgeon may couple the tether 840 to the bone anchor 820 by engaging a tether locking feature 832 with the proximal end 842 of the tether 840. The tether locking feature 832 may serve as a second connector coupled to the bone anchor 820. In certain embodiments, the proximal end 842 may pass through the tether locking feature 832 and thereby tighten the tether 840. The tether locking feature 832 may then be positioned within the body 822 of the bone anchor 820.	114	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	FIG. 11 illustrates a result of a subsequent set of steps in the method or procedure in accordance with one embodiment of the present disclosure after steps described in relation to FIG. 10. FIG. 11 illustrates that the surgeon has pulled the tether 840 through the bone tunnel 862 until the articular implant 900 is embedded into the bone pocket 864 of a distal articular surface 860 of the metatarsal bone 816 (e.g., a natural articular surface 260).	113	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	A surgeon may pass a suture threader 910 through the bone tunnel 862 from the proximal end 866 to the distal end 868 and bone pocket 864. The surgeon may thread the proximal end 842 through a loop in the suture threader 910. Next, the surgeon may pull the suture threader 910 out of the bone tunnel 862 from the proximal end 866 and thereby pass the proximal end 842 of the tether 840 through the bone tunnel 862.	112	Added by DJM 2 2022	2/5/22, 12:00 AM
View Edit Delete	VIL-12	FIG. 10 also illustrates an articular implant 900. An articular implant 900 is an implant configured for use on at least part of an articular surface such as the distal articular surface 860 of the metatarsal bone 816. In the illustrated embodiment, the articular implant 900 may be configured similar to the arthroplasty implant 810. A distal end 844 of the tether 840 may be coupled, connected, or tied to the articular implant 900 (e.g., by way of a first connector such as connector 530, the first connector may be an opening in the articular implant 900). The proximal end 842 of the tether 840 may be free.	111	Added by DJM 2 2022	2/5/22, 12:00 AM
