An expandable interbody fusion device and an associated instrument for inserting the device into an intervertebral disc space, expanding the device and for use in delivering graft material into the device once expanded in the disc space. The device is small enough to fit through Kambin's triangle yet is capable of expanding both in the vertical direction to accommodate spinal lordosis and in the lateral direction to provide sufficient structural support for opposing vertebral bodies laterally within the disc space. A process of forming textured top and bottom surfaces of the device by initially laser ablating each surface with a nano-second pulsed laser followed by laser ablating those surfaces with a femto-second pulsed laser.

A device for safely approaching vertebral disc space utilizing stereotactic guidance, clearing material from the disc space, a device for expanding the disc space, stereotactic methods for implant planning and monitoring articulating instrument end effectors and a device for implantation into the disc space for the purpose of fusion or disc replacement.

The present invention relates to an apparatus, system and method for delivery of bone graft material in a patient's spine. The graft delivery device according to various embodiments delivers and disperses biologic material to a disc space and without withdrawal from the surgical site. In one embodiment, the graft delivery device includes a plunger with a distal end configured to bend relative to a longitudinal axis as bone graft material is delivery to the disc space. The plunger can include two arms that extend generally parallel to the longitudinal axis. The graft delivery device may selectively deliver a fusion cage for deposit to the same disc space.

A prosthetic implant shaped as a portion of a human skeletal structure and including a contact and delivery portion shaped as a porous structure, in particular as a trabecular type structure, suitable for receiving a medical substance and configured to be arranged in contact with a bone of a patient during an operating configuration of the prosthetic implant and a support portion, coupled to the contact and delivery portion, including a plurality of ducts each having at least one inlet section, made at an operative part of the prosthetic implant that can be accessed from the outside by the surgeon in the operating configuration, and at least one outlet section which opens into the contact and delivery portion. The contact and delivery portion is configured to deliver the medical substance evenly onto the bone when the medical substance is injected through at least one duct of said plurality of ducts during the operating configuration.

A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

A modular jaw for attachment to an orthopedic implant extraction tool that includes an elongated body, a claw about a distal end of the elongated body for engaging an object, and a locking mechanism about a posterior end of the elongated body for engaging the orthopedic implant extraction tool. The locking mechanism includes a dovetail lock, a detent mounted to the dovetail lock, and a distally facing surface about a proximal end of the elongated body.

A method of attaching prosthetic implants to bone, applicable to tibia, patella, acetabulum, glenoid, or femur, includes trimming an articular surface of the bone, leaving a trimmed surface. Holes are punched or drilled into the surface in a predetermined array before polymethyl methacrylate bone cement is used to attach the surface to the implant. In an embodiment, the holes are punched by placing a punch-plate with sharpened punch spikes on the surface, and striking the punch plate to drive punches into the trimmed surface. In another embodiment, holes are drilled using a drilling template with predrilled guidance holes placed on the surface of the bone. In another embodiment, holes are drilled by positioning a robotic drill over the trimmed surface; adjusting a drilling pattern of the robotic drill according to the trimmed surface; and using the robotic drill to drill holes of predetermined depth according to the drilling pattern.
