A surgical navigation tracker assembly including a rotational adapter for removably attaching a tracker to a surgical instrument assembly including a surgical handpiece. The adapter may be coupled to an end effector of the surgical instrument and configured to allow the end effector to actuate relative to the adapter. The end effector may comprise a stop, the adapter configured to abut the stop when coupled to the end effector. The adapter may comprise a mount for releasably securing the tracker to the adapter. The adapter may also comprise a biasing element, and the biasing element may comprise an abutment interface configured to engage either of the surgical handpiece or the stop when the end effector is coupled to the surgical handpiece. The biasing element is configured to limit rotation of the adapter relative to the surgical handpiece when the abutment interface is engaged with the surgical handpiece or the stop.

Rotational tracker adapter with biasing mechanism

An expandable rod system includes a first rod portion having an internal cavity, a second rod portion sealingly positioned within the internal cavity of the first rod portion and moveable in a first axial direction relative to the first rod portion, and an osmotic chamber for receiving an osmotic agent to facilitate movement of the second rod portion to expand the rod system. The rod system includes a lock assembly engageable with the second rod portion to prevent the second rod portion from moving in a second axial direction. The lock assembly includes a tapered ramped portion and a bearing member that is moveable within the tapered ramped portion such that when compression forces are imparted on the second rod portion, the bearing member becomes wedged in the tapered ramped portion.

Orthopedic growing devices

A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

Interbody implants and optimization features thereof

Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.

Partially resorbable implants and methods

A system for implanting an expandable interbody implant into an intervertebral space includes an elongated tool, the distal end of which is removably securable to the implant. The proximal end of the tool has an attachment interface for detachable securement to a plurality of different modules, each of which is adapted to effectuate a different function of the delivery system. The different functions include: grasping the implant delivery tool, providing an impaction surface for driving the advancement of the implant, supplying a graft material into the implant, and actuating the expansion of the implant. One of the modules may include a fluid delivery system for supplying hydraulic fluid to expand the implant. A fluid reservoir of the fluid delivery system may be oriented transverse to the cannula that delivers the fluid to the implant. A grafting block can be used to help pre-pack the implant with graft material.

Instruments for expandable interbody implants

A tool for creating an incision at a surgical site includes a body for use with a robotic end effector having a proximal end and a distal end, and a blade positioned at the distal end of the body, the blade having a proximal end and a distal end, the blade having a cutting edge defining a first portion extending outwardly from or adjacent to the proximal end to a maximum width and a second portion extending inwardly from the maximum width to a sharp distal tip.

Incision tools and methods of use

A surgical tool for use with a drill bit to prevent skiving at an implant insertion site on a bone includes a cannulated sleeve having a distal end defining a burr surface. The distal end may be detachable from a body of the cannulated sleeve. The tool may be used with more than one distal end, each of the distal ends defining a burr surface having a different cutting surface from the others. The tool may form a system that includes the drill bit.

Tools for insertion of a spinal implant and methods of using same

A polyaxial screwdriver for inserting a bone screw in a vertebra. A polyaxial bone screw assembly includes a coupling element. When a screw engaging end of the polyaxial screwdriver is lowered on the head of the bone screw, the complimentary surfaces of the screw engaging end of the screwdriver and the head of the screw self-align. A ratchet mechanism formed in the screwdriver provides progressive and automatic locking of the polyaxial screwdriver to the coupling element and prevents the accidental unthreading from the coupling element. In another embodiment of the polyaxial screwdriver, a collet slides over the outside surface of the upper end of the coupling element and locks on to the coupling element. In yet another embodiment of a polyaxial screwdriver, the outer sleeve of the polyaxial screwdriver has a split end that securely engages the coupling element.

Polyaxial screwdriver for a pedicle screw system

An intervertebral implant may include an input for expanding at least two extendable support elements connected to a body at respective locations, such that the extendable support elements each apply a respective expansion force directed away from a surface of the body. Application of a single input force to the input may induce the extendable support elements to apply different amounts of expansion force. Alternatively or additionally, an intervertebral implant may include at least two portions connected together by a hinge for articulation about the hinge. In one aspect, the hinge may include at least two rigid links each pivotably connected to the two portions. In another aspect, a rigid link of the hinge may include a passageway for communicating a hydraulic fluid between the two portions. A locking system may be positionable into successive locked configurations by operation of a cam to prevent contraction of an extendable support element.

Expandable interbody implant with lateral articulation

A bone fastener includes a head, and a screw portion extends from the head. The screw portion includes a shaft and a thread extending along and about the shaft. The thread has a height extending from a root to a tip thereof. The thread also has first and second portions disposed between the root and the tip. The second portion has a porous structure configured to promote bone ingrowth and has a porosity greater than that of the first portion.

Orthopedic screw and porous structures thereof

A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.

Expandable interbody implant with lordosis correction

A system for percutaneous spinal fusion may include two spaced apart blades connected together by a coupling such that the blades define a percutaneous pathway from a skin incision to an implanted pedicle fastener. The coupling may be c-shaped and may have at least one flexible tab for engaging one or more holes along the length of the blades. If one of the blades becomes disconnected from the pedicle fastener, a supplemental access device may be provided comprising a tubular body having a channel therein for receiving the other of the blades. If both of the blades become disconnected, a supplemental access device may be provided comprising a gripping member received within a locking member. The gripping member may have two legs engageable with the pedicle fastener, and the locking member may move along the gripping member to prevent the legs from disengaging the pedicle fastener.

Systems and methods for percutaneous spinal fusion

Hydraulically expandable spinal rods and methods of use thereof are disclosed. The spinal rod may include a piston rod, a static rod, and a hydraulic pressure chamber for accepting hydraulic fluid and causing the piston rod to move in an expansion direction relative to the static rod. Upon connection of the piston and static rods to a patient's spinal column, the hydraulic spinal rod may be expanded to aid in correction of an underlying spinal deformity.
