Claim:
1. A linking member for linking a derotator member to a transverse member in a system useful for correcting alignment of one or more vertebrae of a spine, said linking member comprising: a distal end portion and a proximal end portion; said distal end portion comprising a first opening configured to receive and releasably engage with a proximal end portion of the derotator member; said proximal end portion comprising a second opening configured to receive and releasably engage with the transverse member, wherein said second opening is oriented transverse to an orientation of said first opening; a surface defining said first opening comprising a keyed inner surface configured to maintain an angular orientation of said linking member relative to a transverse axis of the derotator member when said linking member is engaged with the derotator member; and a locking element movable from a locked configuration to an unlocked configuration and vice versa, wherein, when in said locked configuration, said locking element extends into said first opening; wherein said proximal end portion is articulatable relative to said distal end portion in three dimensions; and wherein said keyed inner surface is multifaceted and permits selection from more than two different angular orientations of said linking member relative to the transverse axis of the derotator member, wherein said linking member is maintained in a selected angular orientation once engaged with the derotator member at the selected angular orientation.
