View Edit Delete	IPP-0050-US35 nextremity	FIG. 39 is a perspective view of one embodiment of a guide;	46	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	In the illustrative example of FIGS. 1-9, each leg 124, 126 further includes an elongate outboard surface 148, 150 facing away from the insertion axis 102 and extending from the leading end to the trailing end. In the illustrative example of FIGS. 1-9, the elongate outboard surfaces 148, 150 are parallel to one another and the insertion axis 102.	79	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	Referring to FIGS. 10-14, a hole forming guide 200 includes a body 202 defining hole axes 204, 206 along which a hole forming tool may be guided. In the illustrative example of FIGS. 10-14, the axes 204, 206 are defined by cylindrical guide holes 208, 210. The guide holes 208, 210 are operable to receive a hole forming tool such as a punch or drill and constrain the hole forming tool to longitudinal motion along the axes 204, 206 to form holes in an underlying bone. The axes 204, 206 are angled to correspond to the divergent legs of the fastener of FIGS. 1-9. The inboard surfaces of the guide holes 208, 210 have a guide hole inboard surface leading end spacing 212 at the leading end 214 of the guide 200 that is equal to or greater than the inboard surface trailing end spacing 165 of the fastener. If the guide hole inboard surface leading end spacing 212 is equal to the fastener leg inboard surface trailing end spacing 165, the inboard surfaces 128, 130 of the fastener legs will just touch the inboard surfaces of the bone holes when the fastener leg trailing ends are inserted flush with the bone surface. Further seating of the fastener legs below the surface of the bone will result in compression of the bone between the fastener legs. Likewise, if the guide hole inboard surface leading end spacing 212 is greater than the fastener leg inboard surface trailing end spacing 165, the inboard surfaces 128, 130 of the fastener legs will just touch the inboard surfaces of the bone holes when the fastener leg trailing ends are proud of the bone surface. Further insertion of the fastener until the trailing ends of the legs are flush with the bone surface will result in compression of the bone. The amount of compression for a given insertion depth of the fastener may be determined by selecting the relationship of guide hole inboard surface leading end spacing 212 to fastener leg inboard surface trailing end spacing 165. With the included angle between the leg inboard surfaces matching the included angle between the hole inboard surfaces, the compression of the bone between the fastener legs is uniform at all positions between the legs normal to the insertion axis and inserting the bone fastener does not create a relative bending moment between the first and second bone portions. An insertion axis is an axis along which an object is inserted. An insertion axis may also be the same axis used to extract an object. The guide 200 further includes a guide slot 216 connecting the holes 208, 210. The slot 216 may be used to guide a chisel, broach, saw or other cutting tool to remove bone and form a connecting slot between bone holes formed using the guide holes 208, 210 for receiving the fastener body 104. Alignment notches 218 are provided to indicate the center of the guide 200. Fixation holes 220 are provided to receive fixation pins or screws to fix the guide in position on a bone.	87	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	The fastener 100 may be provided as a plurality of fasteners that have different sizes to accommodate different anatomy. In one example, the fastener is provided as a plurality of fasteners of varying leg length 127 with the leg width 121, depth 123, outboard wall 148, 150 spacing, and divergence angle being the same for each fastener. In this way differing bone thicknesses may be accommodated while using the same instruments described below.	86	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	The aperture 118, if present, is sized to receive an appropriate cross fixation fastener. In one embodiment, its length 120 is as long as possible, and corresponds to an angular variation, that gives maximum flexibility for cross fixation placement without colliding with the legs.	85	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	The leg length 127 may be close to the bone thickness along the insertion axis 102. The legs may be the same length or different lengths and they may be staggered at one or both ends. In the illustrative example of FIGS. 1-9, the leg lengths are different and the legs are level at the proximal end but staggered at the distal end. For use in foot surgery, the leg lengths may be in the range of 10-50 mm and, in one embodiment, in the range of 14-32 mm. For use at other locations, the leg length may be outside of these ranges and can be, for example, quite long in large implants for applications such as tibial osteotomies.	84	Added by DJM 12 2021	12/2/21, 12:00 AM
View Edit Delete	IPP-0050-US35 nextremity	As stated above, the body leading and trailing end recess distances 170, 172 may be equal to or greater than the local bone cortex thickness. The distances 170, 172 may be in the range of 1-8 mm and may vary for different size implants and different applications.	83	Added by DJM 12 2021	12/2/21, 12:00 AM
