In one embodiment, an instrument can include an elongate body having opposed projections extending laterally from a distal portion thereof that can at least partially surround a shank of an implantable anchor such that a longitudinal axis of the elongate body is laterally offset from a longitudinal axis of the anchor. The instrument can further include a lock configured to exert a drag force on a head of the anchor to control polyaxial movement of the instrument relative to the anchor. Further, a proximal portion of the elongate body can be configured to receive a retractor assembly including a plurality of tissue manipulating implements and selectively lock the retractor assembly at any of a plurality of positions along a length of the elongate body. ## Claims ### Claim 1 A surgical instrument, comprising: an elongate body; opposed projections extending laterally from a distal portion of the elongate body that are configured to at least partially surround a shank of an implantable anchor at a position distal of a proximal head of the anchor such that a longitudinal axis of the elongate body is laterally offset from a longitudinal axis of the anchor; a lock configured to exert a drag force on the head of the anchor to control polyaxial movement of the instrument relative to the anchor; and a locking screw disposed within a lumen of the elongate body and configured to adjust the drag force exerted on the head of the anchor; wherein a proximal portion of the elongate body is configured to receive a retractor assembly including a plurality of tissue manipulating implements and selectively lock the retractor assembly at any of a plurality of positions along a length of the proximal portion of the elongate body; and wherein the lock is configured to translate longitudinally relative to the longitudinal axis of the elongate body and directly contact an upper portion of the proximal head of the anchor. ### Claim 2 (depends on 1) The instrument of claim 1, further comprising a biasing element disposed within a lumen of the elongate body and configured to urge the lock into contact with the anchor head to exert the drag force on the anchor. ### Claim 3 (depends on 1) The instrument of claim 1, wherein the lock includes a laterally-extending ring-shaped projection at a distal end thereof that contacts the anchor head while maintaining access to a drive feature formed on a proximal end of the anchor head. ### Claim 4 (depends on 3) The instrument of claim 3, wherein the lock further includes a ring-shaped driver guide pivotally coupled thereto. ### Claim 5 (depends on 1) The instrument of claim 1, wherein the proximal portion of the elongate body includes a plurality of holes formed therein that are configured to receive a locking pin of the retractor assembly to selectively lock the retractor assembly at any of a plurality of positions along the length of the proximal portion of the elongate body. ### Claim 6 (depends on 1) The instrument of claim 1, wherein the proximal portion of the elongate body includes a ratchet configured to interface with a pawl coupled to the retractor assembly to selectively lock the retractor assembly at a plurality of positions along the proximal portion of the elongate body. ### Claim 7 (depends on 1) The instrument of claim 1, wherein the plurality of tissue manipulating implements can be translated laterally relative to the longitudinal axis of the elongate body. ### Claim 8 (depends on 7) The instrument of claim 7, wherein the plurality of tissue manipulating implements can be pivoted about an axis that is transverse to the longitudinal axis of the elongate body. ### Claim 9 A surgical instrument, comprising: an elongate body; opposed projections extending laterally from a distal portion of the elongate body that are configured to at least partially surround a shank of an implantable anchor at a position distal of a proximal head of the anchor such that a longitudinal axis of the elongate body is laterally offset from a longitudinal axis of the anchor; a lock configured to exert a drag force on the head of the anchor to control polyaxial movement of the instrument relative to the anchor; and a locking screw disposed within a lumen of the elongate body and configured to adjust the drag force exerted on the head of the anchor; wherein a proximal portion of the elongate body is configured to receive a retractor assembly including a plurality of tissue manipulating implements and selectively lock the retractor assembly at any of a plurality of positions along a length of the proximal portion of the elongate body; and wherein a distal end of the lock is configured to translate longitudinally relative to the longitudinal axis of the elongate body and engage with an upper portion of the proximal head of the anchor to exert the drag force between the distal end of the lock and the head of the anchor. ### Claim 10 A surgical instrument, comprising: an elongate body; opposed projections extending laterally from a distal portion of the elongate body that are configured to at least partially surround a shank of an implantable anchor at a position distal of a proximal head of the anchor such that a longitudinal axis of the elongate body is laterally offset from a longitudinal axis of the anchor; and a lock configured to exert a drag force on the head of the anchor to control polyaxial movement of the instrument relative to the anchor; wherein a proximal portion of the elongate body is configured to receive a retractor assembly including a plurality of tissue manipulating implements and selectively lock the retractor assembly at any of a plurality of positions along a length of the proximal portion of the elongate body; wherein the proximal portion of the elongate body includes a ratchet configured to interface with a pawl coupled to the retractor assembly to selectively lock the retractor assembly at a plurality of positions along the proximal portion of the elongate body, and wherein the lock is moveable along the longitudinal axis of the elongate body for entering a distal end of the lock into a frictional engagement with an upper portion of the proximal head of the anchor to exert the drag force between the distal end of the lock and the head of the anchor.
