include a threaded hole either extending from or bored into the fixation surface 114 of the inferior implant 110 the manner in which the inferior implant 104 and the translaminar fixation mechanism 106 interact may vary with different anatomies for example it may be preferable to offset the translaminar screw 106 from the inferior implant 104 such that when the translaminar screw 106 and inferior implant 104 interact the translaminar screw 106 is not perpendicular to the inferior implant 104 the translaminar screw 106 may range from about 0 degrees offset from perpendicular to about 20 degrees offset from perpendicular in one exemplary embodiment the translaminar screw 106 ranges from about 5 degrees offset from perpendicular to about 15 degrees offset from perpendicular in another exemplary embodiment the translaminar screw 106 is about 10 degrees offset from perpendicular the articulating surface 112 of the inferior implant 104 in one exemplary embodiment is generally configured to articulate or interact with the articulating surface 108 of the superior implant 102 accordingly the articulating surface 112 of the inferior implant 104 may be generally convex the inferior implant 104 articulating surface 112 may be configured such that it acts as a u201c male u201d surface wherein it is convex.
