Paragraph Number

163

In the illustrated embodiment, one or more engagement interfaces may be present. Referring still to FIGS. 54 and 55, one example engagement interface may be formed by an inferior surface 1044 of a collar 1004 and a superior surface 1046 of an inserter 1008 (e.g., a superior surface 1046 of a coupling member 1032 of the inserter 1008) and/or a superior surface of a bone fastener. Another example of an engagement interface may be formed by an inferior surface 1048 of pin extending distally from an inferior surface 1044 a collar 1004 and a superior surface 1050 near a distal end of a socket 1030 of an inserter 1008 and/or of a bone fastener. The one or more engagement interfaces 1042 constrain rotational movement of the inserter 1008 and/or the collar 1004 about an engagement axis.
