The delivery device includes a distal end, a proximal and a lumen extending from the distal end to the proximal end. The annular anchor is removably coupleable to the distal end of the delivery device. The annular anchor is implantable at a target site, such as a vertebral body in a patient via manipulation of the delivery device. The delivery device is extendable outside the patient when the anchor is implanted at the target site. The implant is deliverable through the delivery device to the target delivery site and implantable through the annular anchor. The delivery device is coupled to the annular anchor to control a trajectory of the implant to the target site.
The system for manipulating implants coupled by a cord include a tensioner and a counter tensioner. The counter tensioner may be releasably coupleable to a head of an implant at a proximal end thereof and may guide the cord to a port proximate the distal end thereof, the port for receiving the nose assembly. The counter tensioner may enable translation of the implant relative to another implant implanted in an adjacent or nearby vertebrae. The indicator region of the piston may be visible through a window in a tensioner main body and may indicate cord tension when the nose assembly of the tensioner is coupled to the port of the counter tensioner and engaged with the cord.

SURGICAL CORD TENSIONING DEVICES, SYSTEMS, AND METHODS
A system (100) for manipulating implants coupled by a cord (108) includes a tensioner (102) and a counter tensioner (104). The tensioner includes a nose assembly (110) and a cord lock assembly (112) for applying tension to the cord. The nose assembly includes a piston (226) having a lumen (228) extending therethrough for receiving the cord and a spring (230) positionable in contact with an indicator region (120) of the piston. The counter tensioner is releasably coupleable to a head of an implant at a distal end thereof and guides the cord to a port proximate the proximal end thereof, the port for receiving the nose assembly. The counter tensioner enables translation of the implant relative to another implant implanted in an adjacent or nearby vertebrae. The indicator region of the piston is visible through a window in a tensioner main body and indicates cord tension when the nose assembly of the tensioner is coupled to the port of the counter tensioner and engaged with the cord.

A torque limiter can include a housing and a shaft. The housing can include a housing magnet enclosed within the housing. The shaft can be at least partially surrounded by the housing and can be rotatable within the housing. The shaft can include a shaft magnet integrated with the shaft to magnetically couple with the housing magnet to transmit a torque between the housing and the shaft and configured to uncouple from the housing magnet allowing the shaft to rotate within the housing when a threshold torque is reached.

ARTICULATING DEROTATORS FOR DEFORMITY SPINAL SYSTEMS
A surgical derotator instrument comprises a shaft, a handle and an articulating coupler. The shaft comprises a first end portion having a bone anchor coupling and a second end portion opposite the first end portion. The handle comprises a body portion and a slot extending in the body portion. The articulating coupler connects the shaft and the handle. A method for coupling a plurality of derotator instruments into a series of derotator instruments comprises: attaching a plurality of derotator instruments to a plurality of adjacent bone anchor housings, each derotator instrument comprising: a shaft for connecting to a bone anchor housing, a handle having a slot, and an adjustable coupler connecting the shaft and the handle; adjusting one or more of the adjustable couplers to align at least one of the slots of the series with other slots of the series; and inserting an elongate member through the at least one slots that are aligned.
A bone fastener system can comprise a fastener and a first sizing component. The fastener can comprise a shaft that provides an anchoring footprint. The first sizing component can be configured to be connected to the shaft and can include a first anchoring feature, or circumferential bone engaging feature, to increase a size of the anchoring footprint. The first anchoring feature can comprise a sleeve that radially expands a diameter of the threaded shaft. The first anchoring feature can comprise axially extending teeth. The system can further comprise a second sizing component including a second anchoring feature to increase the size of the anchoring footprint, the second anchoring feature being different from the first anchoring feature. The second anchoring feature can expand the diameter of the threaded shaft a greater amount than the first anchoring feature. The second anchoring feature can have a length greater than the first anchoring feature.
