Abstract: Assemblies, systems, kits, and methods related to an endoprosthetic rotating hinge assembly. The exemplary embodiments disclosed herein can comprise a preassembled rotating hinge subassembly having a hingedly rotating femur box configured to be mechanically engaged to a femoral component via a femur fastening mechanism, the femur fastening mechanism being non-axially aligned with a tibial axis of rotation when the knee is in flexion or extension.

Abstract: A tunnel connector for an in-ground storm shelter which allows inhabitants to enter the in-ground storm shelter from a trailer house without being exposed to external environmental factors. The tunnel connector includes a U-shaped enclosure wall, a staircase, a first lateral wall, and a second lateral wall. The first lateral wall and the second lateral wall are connected perpendicular to the staircase across each other to provide lateral protection. The U-shaped enclosure wall includes a first sidewall, a second sidewall, and an interconnecting sidewall. The interconnecting sidewall is terminally connected in between the first sidewall and the second sidewall. The first lateral wall is adjacently connected to the first sidewall, opposite the interconnecting sidewall. Similarly, the second lateral wall is adjacently connected to the second sidewall, opposite the interconnecting sidewall. The tunnel connector is installed in between a floorboard of the trailer house and the in-ground storm shelter.

Abstract: A knee prosthesis includes a femoral component for mounting to the distal end of the patient's femur and a tibial insert component. The femoral component includes a posterior cam extending between the lateral condylar structure and the medial condylar structure. The tibial insert includes a lateral bearing surface, a medial bearing surface, and a raised post portion having a posterior surface adapted to cooperate with the posterior cam of the femoral component. The posterior surface includes a posteriorlateral camming surface and a posteriormedial camming surface and each of the two camming surfaces have different radii of curvature. Between 60° to 90° of knee flexion, the posterior cam of the femoral component engages the raised post portion of the tibial insert and cooperates with the posteriorlateral and the posterior medial camming surfaces to promote posterior translation of the lateral condylar surface on the lateral bearing surface.

Abstract: A modular humeral prostheses for replacement of the humeral head of a humerus. The prosthesis generally comprises a stem for insertion in the medullary canal of the humerus, a head for replacing the natural humeral head, and a connecting member for connecting the head to the stem. Specifically, the connecting member of the prosthesis and the engagement of the connecting member to the head provides varying degrees of eccentricity as desired.
