A method for determining the transverse axis for flexion of a condylar ended bone comprises the steps of: conducting a computer tomographic (CT) scan from the end of the condyles inwardly, transverse to the transverse axis of the limb (or extremity) with the joint flexion plane facing forwardly. One then selects the CT slice image exhibiting maximum epicondylar width and establishes a line between the epicondyles at the widest extent. A line is then established joining the posterior condylar tangents on the CT image. Measured lines are established from the posterior condylar tangent line at right angles to the said line between said epicondyles; and then the transverse axis of motion as …

Why it's free to use
- Filed April 4, 1997 and granted January 28, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 4, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 4, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
