Abstract
In an embodiment, the methodology of the present invention is based on the use of an intraoperative navigation system and of a compact alignment guide for alignment of implant components. In an embodiment, an alignment guide of the present invention includes a first component fixable to a bone element; a second mobile component, and a third mobile component, wherein the second mobile component and two control mechanisms form a first link, wherein the two control mechanisms are working in parallel to perform adjustments in two degrees of freedom, wherein the third mobile component and three control mechanisms form a second link, wherein the three control mechanisms are working in parallel to perform adjustments in three additional degrees of freedom, and wherein the first link adjustments and the second link adjustments are performed in series to provide a total adjustment of five degrees of freedom relative to the first component.
