Document Type and Number:
Japanese Patent JP2015024138
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To determine a true, three-dimensional mechanical axis of a limb prior to surgery in order to determine the best placement of a surgical device.SOLUTION: A method for positioning a profile of a prosthetic component on a three-dimensional model of a limb comprises: a. gathering patient-specific anatomical data of the limb; b. identifying first and second anatomical landmarks to determine a first spatial relationship; c. identifying a third anatomical landmark to determine a second spatial relationship with respect to the first spatial relationship; d. positioning the profile of the prosthetic component in all but one degree of freedom; and e. identifying a fourth anatomical landmark and positioning the profile of the prosthetic component in the one remaining degree of freedom.
