    摘要: A knee joint prosthesis includes a femoral component having a first condylar bearing surface and a second condylar bearing surface. Each of the first and second condylar bearing surfaces has a cross-section in a coronal plane that exhibits at least two different radii. The prosthesis also includes a tibial component and an insert component associated with the tibial component. The insert component has bearing surfaces that are complementary to the first and second condylar bearing surfaces, wherein a contact point is established between the bearing surfaces of the insert component and the first and second condylar bearing surface. In accordance with the present invention and as a result of the above construction, varus and valgus rotation of the femoral component relative to the insert component causes the contact point to move laterally as the knee is rotated. By shifting the contact pointy laterally/outwardly, the knee stability (i.e., stiffness) gradually increased.

    摘要: A prosthetic joint according to the present invention includes a first implant component for attachment to a first bone and a second implant component for attachment to a second bone. The first implant component has a condylar portion that includes first and second condylar bearing surfaces and similarly, the second implant component has bearing surfaces that receive and are complementary to the first and second condylar bearing surfaces. Each of the first and second condylar bearing surfaces and each of the bearing surfaces of the second implant component has a cross-section in a coronal plane that exhibits two different radii and a contact point is established between the first and second condylar bearing surfaces and the bearing surfaces of the second implant component. The bearing surfaces of the respective implant components are configured such that varus and valgus rotation of the first implant component relative to the second implant component causes the contact point to move outwardly.

    摘要: A bone prosthesis for the leg and thigh comprises a distal femoral component that includes a body portion adapted to replace a resected portion of the distal femur and a condylar portion having a spherical surface along its inferior and posterior aspects and an axle hole extending through it in the latero-medial direction at the geometric center of the sperical surface and a proximal tibial component that includes a metal head portion having a cavity opening superiorly and defined by spaced-apart lateral and medial flange portions, each of which has an axle hole. A plastic tibial plateau insert is received in the cavity of the tibial head portion and has a spherical seat matching, receiving and pivotably supporting the femoral condylar spherical surface. A plastic bushing is received in the axle hole of each tibial flange portion, and a metal axle is received in the femoral and tibial axle holes. Clearances between the bushings and the portions of the axle received in the bushings provide latero-medial flexural and axial rotational laxities in the prosthetic joint throughout the range of flexural motion. A shaft component is used interchangeably to replace portions of the tibial and femoral shafts. A diaphysis component is provided or total femoral replacement. A proximal femoral component, used in conjunction with the shaft component or diaphysis component, replaces the femoral part of the hip joint. Identical Morse-type taper couplings are used to connect shaft components to joint components.

    摘要: A backlit temperature control knob for water heater valves used with water heaters and more particularly to gas water heaters provides a way to read the temperature indication not previously known in the art. Some embodiments rely on a thermocouple or thermopile normally used to power a safety magnet with the pilot light system as a source of electrical energy to selectively illuminate a Light Emitting Diode (LED) which directs light through at least a portion of the knob to assist in reading the temperature indications.
