An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.

A method of performing a computer-assisted surgical procedure on the spine of a patient comprising the steps of: planning, on a computer, a surgical procedure based on at least one of two- and three-dimensional images of the patient's spine; affixing a robotic assembly over an operative region of the patient; determining, with a computer in communication with the robotic assembly, a desired trajectory of a surgical tool along at least one of an access path and an implant path towards the surgical target site; and placing at least a portion of the surgical tool through the aperture along said desired trajectory along at least one of said access path and said implant path towards the surgical target site.

A surgical instrument includes an implant, a grip, and a pre-set breaking point connecting the implant and the grip. The implant has a joining profile.

A spinal interbody implant has a bone screw retention mechanism that prohibits bone screws from backing out after the bone screws are installed. A bone screw retention plate is received in a plate retention area of the implant to provide a barrier that keeps the installed bone screws from backing out of their bone screw pocket. The bone screw retention mechanism consists of a retention plate and a configured plate retention area in a face of the implant body. Retention plate fasteners may be used to retain the configured plate. In one form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt. In another form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

Systems, devices, and methods are described for providing orthopedic knee inserts. The orthopedic knee inserts include a surface portion having a lip configured to couple with a mating member of a tibial component, where the lip has recesses that define non-continuous contact regions between the lip and the mating member of the tibial component. Alternatively, or additionally, in certain embodiments the mating member includes a shelf for mating with an insert, the mating member having a plurality of splines disposed along the shelf that form non-continuous contact regions between the mating member and the insert.

A stabilization device is provided including an axle and a portion that can be affixed to a bone. The device is used to stabilize a joint while allowing motion of the joint along its natural trajectory and it is placed internally in order to prevent pin tract problems. Additionally, methods for using the device are provided that include, in various sequences, inserting the axle into a bone of a joint, adjusting the geometry of the device and attaching the fixable portion to another bone of the joint. The device can be provided as part of a system including an axis trajectory guide useful for locating the axis of rotation of the joint prior to insertion, adjustment and attachment of the device.
