Title:
ARTIFICIAL IMPLANT FOR ATLAS-AXIS (C1-2) LATERAL JOINTS AND METHOD OF USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/155789
Kind Code:
A3
Abstract:
The joint implant of the present invention is fitted into C1-2 lateral joints through the back of the neck instead of oral approach to avoid infections. It is made of 2 inter-digitating components. One part of the joint implant has a circular railing circumference of a circle, the center of which is odontoid, that inter-digitates in a corresponding circular channel of the other part. Two such implants are fixed on both sides of C1-2 joint simultaneously along the circumference. The circular railings provide mainly circular motion in clockwise and anti-clockwise direction. With some degree of play in channel and rail and making the interacting surfaces of the implant convex on convex, provides the gyroscopic motion with lateral and translational movement and also coupling (vertical translation on rotational movement). This gyroscopic design makes it universal and is likely to work in C1-2 joints of every individual with any possible joint orientation.
