Shape memory locking device for orthopedic implants

摘要

The invention provides a locking mechanism based on shape memory effect and super-elasticity of shape memory materials. A locking mechanism to connect the supporting portions of orthopaedic implants such as in the head, spine, upper limb and lower limb and thereby prevent loosening and fretting at the implant interface of an orthopaedic implant construct has been developed based on shape memory effect and super-elasticity of shape memory materials having at least two shapes in memory selected from the group consisting of metal alloys and polymers.
