For example, a first and a second threaded pin 102 a, 102 b, FIG. 15, may be advanced through the superior and inferior pin sleeve 100 a, 100 b (for example, using a drill or the like) along the superior and inferior axis 101 a, 101 b. The depth of the pins 102 a, 102 b may be controlled using markings (for example, but not limited to, laser markings) disposed on the shaft 104 of the pins 102 a, 102 b.
Once the superior and inferior pins 102 a, 102 b are coupled to the bone, the superior and inferior pin sleeves 100 a, 100 b may be removed from the superior and inferior pin sleeve receivers 99 a, 99 b. Turning now to FIG. 16, the guide block 90 may now be removed from the articular surface along the guide pin 34. The superior and inferior pin sleeve receivers 99 a, 99 b may be provided with slots 104 a, 104 b configured to allow the superior and inferior pins 102 a, 102 b to pass through the guide block 90 as the guide block 90 is slid along the guide pin 34.
Turning now to FIG. 23, a cannulated step drill 134 may be advanced over the pilot drill 130 and the guide pin 34 into the articular surface 16 about the reference axis 32. The use of the pilot drill 130 and the cannulated step drill 134 may be configured to incrementally provide a larger opening in the bone about the reference axis 32 in the articular surface 16 to reduce the potential of chipping the bone about the reference axis 32. The cannulated step drill 134 may also include a depth stop for controlling the depth of the step drill 134 into the bone, for example, as generally described above with respect to FIG. 17 a.
Once the depth of the step drill 134 is set, the step drill 134 and the pilot drill 130 may be removed and a cannulated tap 136 may be advanced over the guide pin 34 as generally shown in FIG. 24. The depth that the tap 136 is advanced into the bone may be controlled based on a marking (e.g., a laser marking) on the guide pin 32. The tap 136 may be configured to provide a threaded opening 138 in the bone about the reference axis 32 to threadably receive the implant post as will be described below.
