A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

The invention describes an artificial knee joint, which includes a femoral condyle prosthesis and a tibial plateau prosthesis, and said tibial plateau prosthesis includes a medial tibial plateau prosthesis and a lateral tibial plateau prosthesis respectively disposed at both sides of the tibial plateau intercondylar eminence. The artificial knee joint further includes a locating pin for fixing the tibial plateau prosthesis. The bottom surface of said tibial plateau prosthesis is provided with a prosthetic notch, and the tibia below said tibial plateau prosthesis is provided with a tibial notch. Said prosthetic notch corresponds to said tibial notch, together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the medial tibial plateau prosthesis and the lateral tibial plateau prosthesis.

A semi-condylar artificial knee joint includes a femoral prosthesis and a tibial prosthesis, and the cross-section of said tibial prosthesis is of a kidney-like type. The tibial prosthesis is disposed at one side of the tibial plateau intercondylar eminence and is located below the femoral prosthesis. The artificial knee joint further includes a locating pin for fixing the tibial prosthesis. The bottom surface of said tibial prosthesis is provided with a prosthetic notch, and below said tibial prosthesis is provided with a tibial notch. Said prosthetic notch corresponds to said tibial notch, and together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the tibial prosthesis and the tibial plateau intercondylar eminence.

A prosthetic disc can take the form of a sensing artificial disc that includes a resilient core and at least one sensor configured to sense one or more conditions within and/or experienced by the disc. The sensing artificial disc can serve as a replacement to a failed or injured disc between two vertebrae of a spine. The sensing artificial disc can include at least one element configured to change a condition or property of the resilient core in response to a condition sensed by the at least one sensor. A prosthetic disc can include therapeutic system configured to deliver medication to the body, which can include a reservoir of medication.

A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

A system for manipulating energy transferred by members defining a joint. The system includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint. There is also an adjustable energy absorbing device attached to the first attachment structure and second attachment structure, wherein adjusting the energy absorbing device changes the load manipulating characteristics of the energy absorbing device.

An artificial joint is provided. The artificial joint may comprise: a first joint member including a first bone replacement part, and a (1-1).sup.st branch and a (1-2).sup.st branch branched from opposite sides of the first bone replacement part; a second joint member including a second bone replacement part, and a (2-1).sup.nd branch and a (2-2).sup.nd branch branched from opposite sides of the second bone replacement part; a first main string connecting one side of the (1-1).sup.st branch and one side of the (2-1).sup.nd branch; a second main string connecting the one side of the (1-1).sup.st branch and one side of the (2-2).sup.nd branch; a third main string connecting one side of the (1-2).sup.st branch and the one side of the (2-1).sup.nd branch; and a fourth main string connecting the one side of the (1-2).sup.st branch and the one side of the (2-2).sup.nd branch.

A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones. In an exemplary embodiment, a coil spring or elastic member is positioned around a piston, and together act to transfer load around a joint during a portion of its range of motion.

A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.
