Abstract:
1. A system for correcting alignment of one or more vertebrae of a spine, said system comprising: a first elongate derotator member comprising a first elongate element having a first proximal end portion and a first distal end portion, said first distal end portion being releasably engageable with a first implant implanted in one of the vertebrae; a second elongate derotator member comprising a second elongate element having a second proximal end portion and a second distal end portion, said second distal end portion being releasably engageable with a second implant implanted in the one of the vertebrae; and a transverse member engageable with said first and second proximal end portions of said first and second elongate elements; wherein a first channel extends axially through said first elongate element and a second channel extends axially through said second elongate element such that a proximal end portion of the first implant can be accessed from a proximal end portion of said first elongate element by inserting a tool through said first channel when said first elongate derotator member is engaged with the first implant and a proximal end portion of the second implant can be accessed from a proximal end portion of said second elongate element by inserting the tool or another tool through said second channel when said second elongate derotator member is engaged with the second implant; and at least one tool configured for insertion through at least one of said first and second channels.
