An instrument for engaging a bone anchor may include a first implant
engaging member having a proximal end and a distal end and a second
implant engaging member having a proximal end and a distal end. The
second implant engaging member may be integrally connected to the first
implant engaging member by a pair of opposed integral spring members
located proximal to the distal ends of the first and second implant
engaging members. Manipulation of the proximal ends of the first and
second implant engaging member can cause each of the distal ends to
rotate about the pair of opposed spring members to engage at least a
portion of a bone anchor. A rod adjusting tool may be connectable to the
bone anchor engaging tool and may be axially adjustable relative to the
bone anchor tool to adjust a spinal rod relative to the bone anchor.
