Abstract: The present invention relates generally to medical devices and methods generally aimed at spinal surgery. In particular, the disclosed system and associated methods relate to performing spinal fixation with the use of a deformity system.

Abstract: This application describes surgical instruments and implants, including a rod reduction instrument, for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. The rod reducer may be passed through the interior of the guide assemblies with a distal end arranged in a first position allowing the distal end to pass through the guide. Once through the guide the distal end may be expanded to provide dual contact on the rod at each end of the bone anchor rod channel.

Abstract: This disclosure describes example embodiments of rod reduction instrumentation and other rod and vertebrae manipulation instruments. The rod reducers can be used during the installation of a rod based surgical fixation system to help urge the rod into the fixation anchors. The reducers described provide various configurations delivering large reduction distance capabilities, strong controlled reduction coupled with an ability to quickly advance the reducer if desired, and reduction of bulk through the surgical corridor.

Abstract: An integral dual rod spinal construct for immobilizing and stabilizing vertebral bodies of the spine is described.

Abstract: The disclosure provides systems and instruments that allow vigorous compression of two bone structures while minimally impeding visual access to the surgical site. This is achieved by use of a sleeve member that connects a stanchion to a lever. The system includes a stanchion member, a sleeve member dimensioned to at least partially encircle the stanchion member, and a compression lever including. The sleeve and the lever form a pivot point to allow the compression lever to rotate relative to the stanchion member when the sleeve is reversibly placed around the stanchion member.

Abstract: Disclosed is a surgical alignment and distraction frame and associated methods of use that facilitates correction of a sagittal imbalance. The alignment and distraction frame works in conjunction with pedicle screw installation guide assemblies to impart the desired correction. The alignment frame can be utilized to ensure the pedicle screw housings are aligned (to facilitate rod coupling) in concert with the completion of a correction maneuver.

Abstract: A bone anchor having a rod housing including a base that has an internal groove oriented at an angle oblique to the longitudinal axis of the base, a capture ring situated within the groove and oriented at an angle oblique to the longitudinal axis, and a bone fastener extending into the rod housing and including a fastener head situated within the base and having a surface that mates with the capture surface of the capture ring to maintain a connection between the bone fastener and the rod housing.

Abstract: Tools and techniques are described that are useful for trauma correction of anterior compression, chance, or burst fractures, particularly where the posterior longitudinal ligament and posterior arch anatomy is still intact. The described tools can be used to reduce fracture and provide additional distraction for ligamentum taxis through a posterior approach that is compatible with both open and minimally invasive methodologies.
