Orthopedic insert measuring system having a sealed cavity
First Claim
1. An insert comprising:
- a flexible articular surface, where the flexible articular surface is an outer surface of a first component;
a rigid load plate where the rigid load plate includes at least one opening;
a first sensor coupled to a first load pad, where the first load pad has an area greater than or equal to a first area of the first sensor;
a second sensor coupled to a second load pad, where the second load pad has an area greater than or equal to a second area of the second sensor;
a third sensor coupled to a third load pad, where the third load pad has an area greater than or equal to a third area of the third sensor; and
a second component, where the load plate is configured to transmit a portion of a load on the load surface to the first, second and third sensors, where the load plate lies between the first and second component, where the first, second, and third sensors lie between the first and second components, where at least one alignment feature extends from the second component through the rigid load plate and couples to the first component and where the portion of the load exerts a force on the first, second, and third sensors and the first, second and third load pads.

Abstract
At least one embodiment is directed to an insert for measuring a parameter of the muscular-skeletal system. The insert can be temporary or permanent. In one embodiment, the insert is prosthetic component for a single compartment of the knee. The insert comprises a support structure and a support structure respectively having an articular surface and a load bearing surface. The height of the insert is less than 10 millimeters. At least one internal cavity is formed when support structures are coupled together for housing electronic circuitry, sensors, and the power source. The internal cavity is isolated from the external environment and can be hermetically sealed. The exterior surfaces of the support structure and the support structure are sterilized.

13. An insert measurement system for measuring loading applied by the muscular-skeletal system comprising:
-
a first component, where the first component includes a flexible articular surface; a second component, where the second component is configured to form a cavity when attached to the first component; a rigid load plate, where the first component is configured to transfer a portion of a load on the articular surface to the load plate, where the load plate is configured to fit within the cavity and where the rigid load plate includes at least one opening; a plurality of sensors configured to fit within the cavity, where each sensor of the plurality of sensors is configured to couple to a corresponding load pad, where the rigid load plate is configured to transmit the portion of the load on the articular surface to the plurality of sensors, and where at least one alignment feature extends from the second component through the rigid load plate and couples to the first component. - View Dependent Claims (14, 15, 16)
