Prosthetic device (10) for temporomandibular joint comprising a first prosthetic component (11), able to be associated with a mandibular condyle (112) of a patient, and a coordinated second prosthetic component (12), able to be associated with a respective glenoid fossa of the patient.

The present invention also concerns a guide device (35) for making an anchoring seating (113) for positioning the first component, and a prosthetic assembly comprising the prosthetic device (10) and the guide device (35).

A distally expanding facet joint implant and delivery device for distally distracting a facet joint. The facet joint implant generally includes an outer part and an inner part. The outer part includes a pair of opposed distally expandable facet plates connected by a hinge. The inner part includes a wedge that is selectively movable against the facet plates to distally expand and contract the facet joint implant into open and closed states. Teeth on the outer part engage indents on the inner part to maintain the facet joint implant in the distally expanded state. The outer and inner parts include outer and inner connectors, and the delivery device includes corresponding outer and inner connectors adapted to be in locked engagement with the outer and inner connectors to hold the implant and selectively cause it to distally expand and contract.

A dynamic disc assembly has a superior end plate, an inferior end plate, and a core. The core has surfaces of an annular Fresnel shape and a linear Fresnel-like shape combined to control the dynamic range of motion (ROM) movement arranged to match anatomical ROM. The core is interposed between and held against interior surfaces of the superior end plate and the inferior end plate. The assembly further has a pair of coupling cords, one coupling cord at each lateral end of the superior and inferior end plates wherein each lateral end of each end plate has one or more cord connections attached and affixed to the coupling cord to form and retain the dynamic disc assembly.

A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a cup and ball joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.

Embodiments of devices, apparatuses, kits, and methods for repairing a human joint by suturing biological tissue to the articular surface of a bone at the joint (e.g., repairing defects in the humerus at the glenoid joint after an anterior shoulder dislocation) are described herein. Biological tissue may include hard tissue such as bone or a joint socket or soft tissue such as cartilage, ligaments, tendons, or muscle tissue.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.

A modular reverse shoulder prosthesis according to embodiments of the present invention includes a stem having a proximal taper and a primary stem axis, the proximal taper extending from the stem about a metaphyseal axis, the metaphyseal axis at an angle with respect to the primary stem axis, a metaphysis having a proximal end, a distal end, a first aperture in the distal end configured to be placed over the proximal taper, and a second aperture in the proximal end having an insert axis that is eccentrically offset from the metaphyseal axis, the metaphysis configured for attachment to the stem at any rotational position of the metaphysis about the metaphyseal axis, and a reverse insert, the reverse insert having a proximal end and a distal end, wherein the proximal end comprises a concave cup formed about a cup axis and configured to receive a glenosphere, and wherein the distal end comprises a locking protrusion, wherein the locking protrusion has an outer surface with a cross-sectional shape that is rotationally symmetrical about the insert axis with respect to a corresponding inner surface of the second aperture, wherein the rotational symmetry has an order of six, seven, eight, nine, or ten.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (“SAI”) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

In the case of known prosthesis systems and socket supplies, the transmission of force is a critical issue. The inventive prosthesis system shall improve known prosthesis systems. According to the invention, a prosthesis system for human limbs is provided, which comprises an implant (101) having at least two joint parts which are movable relative to each other, wherein the first joint part (110) can be connected to a bone part (131, 132) and the second joint part (120) comprises a subcutaneously arrangeable end part (124) on the side being remote from the joint. The invention further relates to a prosthesis system comprising a subcutaneous implant and a socket (170).
