An intervertebral prosthetic disc placement instrument is provided for implantation of an intervertebral prosthetic disc. The placement instrument shaft has a distal end and a proximal end and an instrument handle on the proximal end having an activation mechanism. A pair of grasping jaws on the distal end of the instrument shaft are configured to move with respect to one another to grasp a multipart prosthetic disc in a non-articulating configuration. The grasping jaws are movable from a tightened to a released position by the activation mechanism. A prosthetic disc ejector on the distal end of the instrument shaft moves distally with respect to the pair of grasping jaws when the grasping jaws are in the released position and the ejector is configured to contact the prosthetic disc to fully disengage the prosthetic disc from the placement instrument. An intervertebral prosthetic disc core removal instrument is also provided for use in distracting plates of the intervertebral disc away from one another to allow the core to be more easily removed.

An expandable intervertebral implant is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

A surgical implant and a surgical kit. The surgical implant has a body portion comprising a first hole formed in an exterior surface of the body portion, a second hole adjacent the first hole, and at least one through-hole within the body portion and extending entirely thought a depth of the body portion extending entirely thought a depth of the body portion. The implant has a central opening abutting the body portion and extending through the body portion. The first hole has a first sidewall and a first cavity in the body portion, the second hole has a second sidewall and a second cavity in the body portion, and the first cavity and the second cavity have an interconnected opening there between. The surgical kit includes the surgical implant and an intervertebral insertion device.

A system for use during surgical procedures. The system includes an implant and a tool. The implant combines a modular adjustable cage and a shim that locks the cage into position, after the cage has been adjusted to its final position and at its final height, in situ. The tool combines an expander and an inserter. A related method of using the system is also provided.

An implant trial includes a trial body and an indicium disposed in the trial body. The trial body is positionable in a subject. The indicium is designed and constructed to indicate a parameter of the implant trial. The indicium is radiographically visible when the trial body is positioned in the subject. The implant trial may be a trial spacer for vertebrae.

A unitary intervertebral device, having no moving components is provided for non-fusion articulation and fusion applications. The interbody articulating device allows for limited flexion and rotation between the implant and an adjacent vertebrae, helping to preserve or restore near-normal motion between adjacent vertebrae. Rotational motion is achieved through one or more protrusions incorporated into the spinal interbody device. In one articulating form, a first protrusion extends perpendicularly from one bearing surface of the interbody device to form a rotational protrusion, while at least a second protrusion extends from the opposite bearing surface of the interbody device to form a non-rotational protrusion. In another form, a single protrusion extends axially from one bearing surface of the interbody device to form a spike or anchoring, rotating protrusion, while the opposite bearing surface may be slightly rounded and/or comprising a bone-ingrowth promoting surface. Similarly configured fusion salvage devices are also described.

An adjustment tool configured to adjust an intervertebral implant comprises a housing, a traveler member, a tether member, and a drive member. The traveler member is coupled to the housing. A proximal end of the tether member is coupled to the traveler, and a distal end of the tether member is configured to couple to the implant. The tether member is substantially linearly fixed to the traveler and rotatable relative to the traveler. The drive member is configured to transition between 1.) a first position in which the drive member is coupled to the tether such that rotation of the drive member causes rotation of the tether relative to the traveler, and 2.) a second position in which the drive member is coupled to the traveler such that rotation of the drive member causes rotation of the traveler relative to the housing.

Hard-tissue implants are provided that include a bulk implant, a face, pillars, slots, and at least one support member. The pillars are for contacting a hard tissue. The slots are to be occupied by the hard tissue. The at least one support member is for contacting the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1. Methods of making and using hard-tissue implants are also provided.

An interbody spinal implant for implantation in a disc space between adjacent vertebral bodies, and an insertion instrument facilitating such implantation is provided. The spinal implant includes a body portion and an extended end portion, where at least the body portion can include a biconvex upper and lower surfaces. And the insertion instrument is engageable to a proximal end portion of the interbody spinal implant to facilitate insertion of the interbody spinal implant into the disc space.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.
