A system for dilating tissue includes a retractor having a pair of retractor blades that are movable towards and away from each other to retract tissue of a patient. The retractor blades have longitudinal guide channels. A first pin is attachable to a first vertebra. The system also includes an interbody spacer insertion device that has a guide channel for slidably engaging the longitudinal channel guide and is releasably attachable to an interbody spacer. The interbody spacer insertion device is configured to guide the interbody spacer into a space between adjacent vertebrae. A method for using the system includes advancing the retractor blades towards first and second vertebrae. The first retractor blade is attached to the first vertebra using the first pin and the retractor blades are moved away from each other. The interbody spacer insertion device is translated towards the vertebrae to position the interbody spacer between the vertebrae.

Sagittal balance systems and methods of use thereof

A rod reducer assembly is provided. The rod reducer includes a pedicle screw housing defining a rod-receiving passage therethrough. A tab is removably coupled to the pedicle screw housing by a frangible member. An extension is secured to the tab. The extension and the tab are separable from the pedicle screw housing upon application of a threshold force to the frangible member.

Extended tab systems for reducing spinal rods

A spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper end plate including an outer surface extending between first and second end surfaces and opposed side surfaces. The outer surface includes a first convex profile extending between the first and second end surfaces and a second convex profile extending between the opposed side surfaces. The first convex profile and the second convex profile have different curvatures. The spinal implant further includes a lower end plate and a core disposed between the upper and lower end plates and coupled thereto. A method of assembling a spinal implant and a method of performing spinal surgery are also disclosed.

Cervical disc and instrumentation

A retractor system includes first and second fixation pins and a retractor assembly including first and second retractor bodies. Each of the first and second retractor bodies includes a main panel and extension panels extending from the main panel. Each of the first and second retractor bodies is transitionable between a first configuration, in which, each of the first and second retractor bodies is substantially flat, and a second configuration, in which, each of the first and second retractor bodies has a substantially U-shaped profile such that the extension panels oppose each other. The extension panels of the first retractor body are configured to selectively overlap the respective extension panels of the second retractor body when the first and second retractor bodies are in the second configuration.

Spinal retractor and method of use therefor

A swivel distractor includes a blade portion, a flange, and a distraction portion. The flange extends at an angle from a first end of the blade portion. The distraction portion is pivotally coupled to a second end of the blade portion opposite the first end. The distraction portion may include a first foot that is configured to be received in a head of a first pedicle screw and a second foot that is configured to be received in a head of a second pedicle screw. The second foot may be movable relative to the first foot.

Swivel retractor and rigid connection system for retractors

A surgical implant assembly includes a surgical implant, a bone plate, and fixation devices. The surgical implant includes a top surface, a bottom surface disposed in opposed relation relative to the top surface, first and second surfaces interconnecting the top and bottom surfaces, and a front surface. First ends of the first and second side surfaces define a back surface extending across a first end of the surgical implant, and the front surface extends across a second end of the surgical implant and interconnects second ends of the first and second side surfaces. At least one cavity is defined in the surgical implant. The bone plate includes an elongate body extending between first and second end portions. The elongate body is positionable adjacent the front surface of the surgical implant. The fixation devices are configured to secure the surgical implant or the bone plate to osseous tissue.

Pelvic wedge

A screw insertion instrument includes a handle, a driving assembly, and a stylet. The driving assembly extends distally from the handle and includes a knob, a tubular body extending distally from the knob, and a driver including an elongated body extending through the knob and the tubular body. The elongated body has a proximal region operably coupled to the handle and a distal region extending distally beyond the tubular body and engageable with a pedicle screw. The stylet includes an elongated body positionable through first and second longitudinal bores defined through the handle and the driver, respectively. A proximal portion of the stylet is positionable adjacent the handle and a distal portion of the stylet extends distally beyond the driver and is positionable through a third longitudinal bore defined through the pedicle screw such that the distal portion of the stylet extends distally beyond the pedicle screw.

Screw insertion instrument and methods of use

A rod reducer assembly is provided and is selectively mountable to a pedicle screw assembly. The pedicle screw assembly includes a pedicle screw housing that defines a rod-receiving recess. The pedicle screw assembly includes an extension assembly that is coupled to the pedicle screw housing by a frangible member. The rod reducer is configured to reduce a spinal rod into the rod-receiving recess of the pedicle screw assembly. The rod reducer assembly may include a derotation sleeve configured to inhibit the frangible member from breaking while manipulating a spinal bone.

Rod reducer assembly

A surgical instrument includes a housing, an outer shaft, an inner shaft, a trial sizer, a rod, and a head. The outer shaft is operatively coupled with the housing such that rotation of the housing causes axial displacement of the outer shaft. The outer shaft includes a keel cutter configured to form a channel in a vertebral body. The inner shaft disposed within the outer shaft. The trial sizer is configured to be received in intervertebral space. The trial sizer includes a pair of wings transitionable between a retracted position and an extended position in which the pair of wings extends transversely outward. The head is connected to the rod, wherein the head is operatively coupled with the pair of wings such that axial displacement of the rod causes transition of the pair of wings between the retracted and extended positions.
