Systems and methods for robotically preparing a disc space are provided for implantation of an intervertebral prosthetic disc. The system includes three-dimensional modeling to identify positions of vertebrae adjacent a surgical site and a disc selection interface in a computing system to allow the surgeon to select an intervertebral disc prosthesis for implantation. A bone cutting interface allows the surgeon to determine a bone cutting pattern tailored to both the three-dimensional positions of the vertebrae and the selected intervertebral disc. A robot controls a cutting device or guides a cutting device to cut the vertebral bone in the bone cutting pattern.

Robotic system and method for bone preparation for intervertebral disc prosthesis implantation

An implant system comprising a staple and a cage is disclosed. The implant system is secured to the bone by moving the staple rotationally and longitudinally whereby tines of the staple and opposing tines frictionally and mechanically engage or embed themselves in the bone side walls. For vertebral applications, the cage defines an upper surface plane, a lower surface plane and a cage surface angle between these two planes whereby the cage surface angle may alter an endplate surface plane of one or more vertebral body when the cage is implanted in a vertebral body. Implant systems may be configured for use as an interbody or intrabody implant system. The implant system may also be configured for use in arthrodesis procedures with other joints within the body. The implant system may further comprise an anchor frame or plate to further secure the cage and staple to the anatomy.

Systems and methods for tibial plateau leveling osteotomy (TPLO) are disclosed. According to some embodiments, an osteotomy method may include cutting a tibia with an arcuate cut to separate a tibial plateau of the tibia from a tibial base of the tibia, rotating the tibial plateau relative to the tibial base from a first orientation to a second orientation, and, with the tibial plateau in the second orientation relative to the tibial base, securing an implant to the tibia to secure the tibial plateau to the tibial base. Securing the implant to the tibia may include embedding a first leg of the implant into the tibial base, and embedding a second leg of the implant into the tibial plateau such that the first and second legs apply compression urging the tibial plateau toward the tibial base.

An assembly for determining height and angle of an intervertebral device to be implanted in an intervertebral space. The assembly comprises a sizing instrument () comprising a support () attached to first and second arms (), () which extend in generally a same direction from the support. The assembly also comprises superior and inferior endplates (), () of the intervertebral device to be implanted. One of the superior and inferior endplates (), () engages with a distal end of the first arm () and the other of the superior and inferior endplates (), () engages with a distal end of the second arm (), the superior and inferior endplates opposing each other when they are engaged with their respective arms. The distal end of the second arm () performs first and second forms of movement relative to the distal end of the first arm (), the first and second forms of movement being independent of each other, the distal end of the second arm moving along different respective paths in the first and second forms of movement, the first form of movement changing separation between the superior and inferior endplates (), (), and the second form of movement changing an angle between the superior and inferior endplates (), (). The support () comprises a user control which is mechanically coupled to at least the second arm () of the first and second arms to provide upon user operation of the user control each of the first and second forms of movement of the distal end of the second arm.

Systems and methods are provided for robotically assisted disc prosthesis selection and implantation. The system includes a 3D modeling system for creating a 3D model of first and second vertebra adjacent the intended surgical site and identifying and storing data for the positions of the first and second vertebrae. A computing system for stores and processes the 3D model and the position data. A robot connected to the computing system attaches to a plurality of instruments including sizing templates, trials, cutters or placement instruments for intervertebral disc prostheses. An interface on the computing system allows the surgeon to sequentially deliver the plurality of instruments with the robot to a registration position to improve the speed and accuracy of the surgical procedure.

Systems and methods for robotically distracting a disc space are provided for implantation of an intervertebral prosthetic disc. The system includes a 3D modeling system for creating a 3D model of first and second vertebra adjacent the disc space and identifying positions of the first and second vertebrae. A robotic distractor precisely opens the disc space just large enough to receive a selected intervertebral disc. A computing system stores and processes the 3D model and the positions of the first and second vertebrae before and after distraction. A surgeon interface on the computing system allows the surgeon to select an intervertebral disc prosthesis to be implanted and a desired distraction distance or force to be achieved.

The present invention relates to a brace installation instrument placement that is mounted to anchors secured in an animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position a brace in a position more proximate the anchors. The brace can be indexed for insertion at a predetermined orientation with respect to the installation instrument. Methods and techniques for using the installation instrument are also provided.

Instruments and methods for stabilization of bony structures

An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. The invention includes an apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.

Allogenic or xenogenic materials are used to provide intervertebral disc nucleus implants and/or annular plugs. The allogenic or xenogenic materials comprise natural disc annulus material, which may have a portion of the anterior longitudinal ligament attached. The tissue may be used 'as is' without an additional core or covering, or it may be used in combination with other materials. The material may be rolled, folded, layered and/or sutured, stapled, or glued to provide a solid plug of natural biological material. The implant may be provided as a dehydrated, substantially rod-shaped segment having a diameter less than the diameter of the hydrated material, and may have one or more ends of the dehydrated rod terminate with a further reduced diameter portion, preferably a point.
