Cardan Joint Wrist Arthroplasty

ID# 2017-4621
Design Emodiment

Technology Summary

The disclosed invention is an orthopaedic wrist implant for the replacement of a damaged, diseased, or degenerated natural wrist joint. A cardan joint, a universal joint that can bend in any direction, preserves the biomechanics of a natural wrist joint.

Application & Market Utility

The cardan joint prevents wear that would result from metal-to-metal or metal-to-polyethylene contact. The cardan joint also reduces the incidence of implant loosening and displacement, both of which are complications typical to prosthetic joints with bearing surfaces.
