Paragraph Number

97

In the illustrated embodiment, the separation indicator 124 can include a face that may include a number that represents a measure for a displacement between an outer surface of the superior plate 118 and an outer surface of the inferior plate 120. For example, in the illustrated embodiment, a number at the top-most position of the face when viewed as illustrated may represent a current amount of displacement. For example, the “9” may represent a displacement of 9 millimeters. The face on the driver 152 can include a plurality of different marks and/or numbers (e.g., readings) that each may represent a different displacement between the superior plate 118 and inferior plate 120. The fastener 154 may permit the driver 152 to be rotated about a longitudinal axis of the fastener. The driver 152 is rotatable to a plurality of positions and each position may represent a different displacement that corresponds to the number on the face of the driver 152. The illustrated embodiment can include six different displacements and six numbers each representing a different displacement. (e.g., 9, 11, 13, 15, 17, and 19).
