Zimmer Segmental System, Articular Surface with Segmental Hinge Post - Prosthesis, knee, internal, insert component

Intended purpose

The Segmental Articular Surface with Hinge Post is a part of the Zimmer Segmental System and is indicated for Moderate to severe knee instability; Significant bone loss and/or ligament deficiencies caused by neoplasms, trauma, rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, and/or avascular necrosis of the proximal and/or distal femur and/or proximal tibia; Valgus, varus or flexion deformities; The salvage of previously failed surgical attempts.

Functional description

The Segmental Articular Surface is used between the Segmental or NexGen RHK distal femoral component and the NexGen RHK proximal tibial component. Segmental Hinge Post is connected to the Segmental or NexGen RHK distal femoral component with the hinge pin and set screw and slides through the Segmental articular surface and into the NexGen RHK proximal tibial component. Articular Surface is made from UHMWPE, and the Hinge Post from Co-Cr-Mo alloy with a pre-installed bushing made of UHMWPE.
