View Edit Delete	PER-32	FIG. 16G illustrates a cross-section of a reduction guide 1660b deployed on the first fastener 1602 and second fastener 1606 and third fastener 1610 that extend from the bone fragments. FIG. 16G illustrates that the open end slot 1636 may extend from the front surface 1638 to the back surface 1640 and the fastener lock 1666 may extend from the front surface 1668 to the back surface 1670. Alternatively, or in addition, the open end slot 1636 and/or fastener lock 1666 may extend from the respective front surface 1638 and front surface 1668 at an angle selected for the reduction. In one embodiment, the angle of the open end slot 1636 and/or fastener lock 1666 is patient-specific and may be predetermined by a surgeon or confirmed based on a recommendation made to the surgeon. In certain embodiments, the position of the open end slot 1636 and/or fastener lock 1666, the length of the open end slot 1636 and/or fastener lock 1666 from the proximal surface 1646 and/or distal surface 1648 can be predefined such that when the reduction stabilizer 1650 engages the third fastener 1610 not only reduction of the fragments is accomplished but also such engagement can introduce a level of compression of the distal bone fragment 224a against the proximal bone fragment 224b. Of course, because the reduction anchor 1630 and/or reduction stabilizer 1650 may be made specifically for a particular patient, in certain embodiments, deployment of the reduction guide 1660b may provide reduction alone.	274	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	In certain embodiments, the reduction anchor 1630 may also include a bone engagement surface 1680 (See FIG. 16G) to facilitate seating of the reduction anchor 1630 on a surface of one or more bones such as the distal bone fragment 224a. FIG. 16G is a cross section view of the reduction anchor 1630 and reduction stabilizer 1650 deployed for a reduction. FIG. 16G illustrates use of the reduction anchor 1630 for the reduction.	275	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	A surgeon may use the reduction anchor 1630 for a reduction by sliding the first hole 1632 over the first fastener 1602 and the second hole 1634 over the second fastener 1606. Next, the surgeon may slide the reduction anchor 1630 along the fasteners until the back surface 1640 contacts or comes in close proximity to a surface of the proximal bone fragment 224b. In embodiments that include a bone engagement surface 1680, the bone engagement surface 1680 may contact and engage the surface of the proximal bone fragment 224b. Advantageously, the bone engagement surface 1680 may be fabricated such that the bone engagement surface 1680 matches the surface of one or the other or both of the distal bone fragment 224a and the proximal bone fragment 224b when in the desired reduced position. Such a configuration can further assist a surgeon in accomplishing a desired reduction.	276	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	FIG. 16G includes an alternative embodiment of a reduction guide with reduction guide 1660c. In one embodiment, the reduction guide 1660c includes a fastener 1682 configured to couple the reduction anchor 1630 to the reduction stabilizer 1650. Those of skill in the art will appreciate that the fastener 1682 may be any variety of fastener. For example, the fastener 1682 may be two parts of a snap, a screw, a recess and a post, or the like.	277	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	In the illustrated embodiment, the fastener 1682 may include an extension 1684 and a recess 1686. In one embodiment, one extension 1684 may extend from a back surface 1670 of the reduction stabilizer 1650 and fit within and engage with a recess 1686 within the front surface 1638 of the reduction anchor 1630. Alternatively, or in addition, one extension 1684 may extend from a front surface 1638 of the reduction anchor 1630 and fit within and engage with a recess 1686 within the back surface 1670 of the reduction stabilizer 1650.	278	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	FIG. 16H illustrates bones of a patient’s foot with the reduction stabilized by one of the embodiments of the reduction guides 1660a, 1660b. The reduction anchor 1630 is seated on the surface of the bone fragments 224a, 224b. In the illustrated embodiment, the reduction anchor 1630 may be seated across the resection that is now reduced and may contact a surface of both bone fragments 224a, 224b. Advantageously, the bone engagement surface 1680 may be contoured to match the now reduced surfaces and/or section(s). The reduction anchor 1630 engages the first fastener 1602, second fastener 1606, and receives the third fastener 1610 which is now parallel to the first fastener 1602 and second fastener 1606. The reduction stabilizer 1650 also engages the first fastener 1602, second fastener 1606, and third fastener 1610. The resected areas are now reduced and stable such that a surgeon can turn their attention to a next step in a surgical procedure.	279	Added by DJM Jan 2024	1/6/24, 9:49 PM

View Edit Delete	PER-32	The reduction anchor 1630a may also include another open end slot 1637. And the reduction stabilizer 1650a may include another fastener lock 1667.	287	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	The open end slot 1636 and/or another open end slot 1637 are positioned in, and configured in, the reduction anchor 1630a such that when the reduction anchor 1630a is slid along the first fastener 1602 and the second fastener 1606, the open end slot 1636 and/or another open end slot 1637 align with the third fastener 1610 and fourth fastener 1615 that are engaged with a bone fragment 224a. The open end slot 1636 and/or another open end slot 1637 are sized and configured to receive the third fastener 1610 and fourth fastener 1615 when the bone fragments are reduced. In other words, the another open end slot 1637 may function in similar manner to the open end slot 1636.	288	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	The fastener lock 1666 and/or another fastener lock 1667 are positioned in, and configured in, the reduction stabilizer 1650a such that when the reduction stabilizer 1650a is slid along the first fastener 1602 and the second fastener 1606, the fastener lock 1666 engages the third fastener 1610 and the another fastener lock 1667 engages the fourth fastener 1615.	289	Added by DJM Jan 2024	1/6/24, 9:49 PM
View Edit Delete	PER-32	The reduction anchor 1630a and reduction stabilizer 1650a may operate and function in a similar manner to the reduction anchor 1630 and/or reduction stabilizer 1650 described previously. One difference however is that when using the reduction guide 1660d with the resection guide 1020e, after resection using the resection features 1022, the fifth fastener 1611 in the hole 1617 can be removed and the fourth fastener 1615 and third fastener 1610 can remain in the distal bone fragment 224a after resection and during reduction. In this manner, a surgeon can maintain stable and secure control of the distal bone fragment 224a during resection and throughout the reduction stage of a surgical procedure. Those of skill in the art will appreciate that the fastener lock 1666 and fastener lock 1667 can be embodied in other forms and configurations and still meet the subject matter disclosed in the present disclosure.	290	Added by DJM Jan 2024	1/6/24, 9:49 PM
