- the second cutting window 54' differs from the first cutting window 54 in that the two slots 74a, 74b of the first cutting window are spaced from one another by a first distance "dl" and the two slots 74a', 74b' of the second cutting window 54' are spaced from each other by a second distance "d2" different from the first distance "dl”.
- the second distance "d2" between the slots 74a', 74b' of the second cutting window 54' is greater than the distance "dl” between the slots 74a, 74b of the first cutting window 54 (fig. . 10).
- the second cutting window 54' can be used in the case where the amplitude of the cut made with the first cutting window was not sufficient.
- each of the slots 74a, 74b, 74a', 74b' is for example provided in a fixed manner in the cutting guides 54, 54'. In other embodiments, more than two cut windows including varying distances between the slots may be used. In embodiments not illustrated, it is for example possible to propose a single cutting guide 54 which has slots whose positions can be adjusted by means of a mechanism adapted so as to modify the distance between the slots.
- the distance “dl, d2” between the slots 74a, 74b, 74a', 74b' could be between 3 and 10 mm.
- the first slot 74a, 74'a of the cutting window(s) as previously described extends at an angle "a" inclined relative to the second slot 74b, 74b'. This allows you to correct the orientation of the foot.
- the angle “a” is defined in a plane orthogonal to the direction of insertion of the positioning guide.
- the angle “a” is between 5 and 10 degrees, preferably the angle “a” is equal to 5 degrees.
