A surgical device has a shaft including a proximal portion and a distal portion being disposable with a surgical robot guide to engage vertebral tissue. The proximal portion defines a detectable marker and is connectable with at least one surgical instrument for manipulating the vertebral tissue. Systems, surgical instruments, spinal implants, constructs and methods are disclosed.

Implants, instruments, and methods for performing surgical procedures on the spine, including one or more of creating an operative corridor to the spine, delivering implants to the spine, fusing one or more segments of the spine, and fixing one or more segments of the spine.

A clamp assembly for orthopedic use having a housing that includes a top surface, a recess, a distal base and a bottom surface, the recess defining a longitudinal axis and extending through the housing from the top surface through the distal base and toward the bottom surface, and at least two through slots, each one of being disposed at a bottom or a side a surface of the housing. The assembly including a securement assembly positionable within the recess in a co-axial relationship to a mating surface on the recess, and a band sized for travel along a predetermined path defined in part by the through slots in the housing, wherein at least one of the through slots is a starting point for travel of the band along the predetermined path.

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.

A surgical planning and assessment system is disclosed. The system may include a computing system having a processor, a data store, a patient specific planning and analysis module, and a display. The system may be configured to access a database storing a plurality of possible surgical plans. The computing system may store a target surgical plan including a plurality of patient specific inputs including at least one preoperative medical image of a spine of a target patient and analyze the target surgical plan to determine a predicted alignment of the spine of the target patient. The computing system may develop a plurality of predictive models including a predicted alignment of the spine of the target patient based on the target surgical plan and suggest at least one alternative surgical plan with respect to the target surgical plan.

A surgical planning and assessment system is disclosed. The system may include a computing system having a processor, a data store, and a patient specific planning and analysis module. The system may be configured to store a patient specific target plan including a digital representation of a spinal rod having a target geometry and transform the digital representation into a curved line. The system may generate a spline data set comprising a plurality of spline segments that are sequentially linked to one another. The system may adjust, iteratively, each spline segment until the plurality of spline segments approximate the curved line. The system may generate a digital file comprising drawings for manufacturing a spinal rod based on the plurality of spline segments. In various embodiments, each spline segment may be defined by a corresponding arc or a corresponding line extending between a corresponding starting point and a corresponding ending point.

The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

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.

A system and method for the minimally invasive insertion of an intervertebral rod into the vertebrae of a subject, according to a preoperative surgical plan also defining positions for the insertion of rod clamping screws into the vertebrae. The rod shape for connecting the heads of the screws is calculated, and a path planning algorithm used to determine whether the distal end of the rod can be threaded through the screw heads by longitudinal and rotational manipulation of the proximal end of the rod. If so, instructions are provided for forming that rod shape and for the robotic insertion of the screw holes and the rod. If not, either or both of the screw positions and the rod shape are adjusted, to moderate the bends in the rods, until insertion becomes possible. The insertion can be performed robotically, or, if a navigation tracking system is added, manually.

A surgical access system includes a connector including an arm, a coupling element, a rod, and a ridged slider. The arm includes first and second notched sections disposed in opposed lateral sides thereof. The coupling element includes a body section defining an opening therethrough, and opposed tabs protruding therefrom that are configured to receive the second notched section therebetween such that the arm is pivotably coupled to the coupling element. The rod includes a shaft having a plurality of angled grooves defined partially along a length thereof. The rod extends through the opening of the coupling element and the first notched section of the arm. The ridged slider includes a first surface having a plurality of ridges extending along a partial length thereof. The ridged slider extends through the coupling element with the plurality of ridges operably engaged with the plurality of angled grooves of the rod.
