摘要： An orthopedic device having a support structure provided with at least an orifice for a fixing screw associated with a nut; the head of the screw to be pressed on one side of the support, and the nut adapted to be pressed on the other side of the support, in a housing enabling its being integrated at least partly, so as to enable the support structure to be clamped between the screw head and the nut when the screw body has been completely screwed in the receiving bone material. The implantable device includes elements for maintaining the nut in its housing opposite the orifice, and elements for locking the nut in rotation. The contours of the housing and of the nut are dimensioned to provide at least one degree of freedom to the nut in the housing enabling self-centering of the screw and nut.

摘要： The present invention relates to methods for determining meniscal size and shape for use in designing therapies for the treatment of various joint diseases. The invention uses an image of a joint that is processed for analysis. Analysis can include, for example, generating a thickness map, a cartilage curve, or a point cloud. This information is used to determine the extent of the cartilage defect or damage and to design an appropriate therapy, including, for example, an implant. Adjustments to the designed therapy are made to account for the materials used.

摘要： Modular orthopedic implants for joint reconstruction and methods of use therein are described that comprise base, body, and stem components. The base receives an articulating portion on a first end and has a connector on a second end that mates with the body and stem. The tubular body has a tissue engaging external portion, and an internal bore. The stem has an elongated shaft configured to be situated inside of a bone, and a top end having a connector. In a group of two-connection embodiments, the base mates with the body to form a first connection and the base mates with the stem to form a second connection. In a group of three connection embodiments, the stem and body also mate to form a third connection. The connections are combinations of interference fit connections such as press fit, multiple press fit and tapered fit connections.

摘要： Artificial disc (ADR) and joint replacement components, particularly those associated with the knee and hip, use compressible, resilient materials to approximate natural kinematics, often in conjunction with elastic or spring components to tether articulating components to avoid dislocation, excessive compression, flexion or other out-of-range movements. The preferred embodiments require only two or a few articulating components. The designs allow for normal flexion, extension, lateral bending, rotation, and translocation, depending upon the application.

摘要： The present invention is a method of making a lubricious polyacrylonitrile artificial joint of a predetermined form and the resulting product. The method includes preparing a solution of a room temperature solvent that will dissolve polyacrylonitrile at room temperature and a room temperature non-solvent that will not dissolve polyacrylonitrile at room temperature. The solution is prepared with sufficient non-solvent to render the room temperature solvent inoperable for polyacrylonitrile at room temperature and operable at temperatures above 65null C. to dissolve polyacrylonitrile therein. Next, the polyacrylonitrile and the solution are combined into a mixture, in an amount of at least 20%, by weight, of polyacrylonitrile. The mixture is then heated at temperatures in excess of 65null C. to produce a fluid polyacrylonitrile product, and processed into an artificial joint component mold. Next, the product is cooled and may be rinsed, solvent extracted and dried. It is then treated chemically, e.g. with sulfuric acid, to increase hydrophilicity, and lubricity.

摘要： Wheels, bearings, or other rotating elements are used to decrease friction in artificial joint components associated with knee and hip replacements, artificial ankles, elbows, wrist, finger joints, toe joints, and intervertebral discs. One or more seals may be used to trap debris inside the artificial joint. The seal may surround the periphery of the component(s), and may be used to hold a fluid within the joint. Various fluids or lubricants are applicable to these embodiments, including water or aqueous solutions, triglyceride oil, soybean oil, an inorganic oil (e.g. silicone oil or fluorocarbon), glycerin, ethylene glycol, or other animal, vegetable, synthetic oil, or combinations thereof could be used. The seal could be made of an expandable elastomer such as those used in medical devices for the cardiovascular system.
