Abstract
The present invention relates to a brace installation instrument placement that is mounted to anchors secured in an animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position a brace in a position more proximate the anchors. The brace can be indexed for insertion at a predetermined orientation with respect to the installation instrument. Methods and techniques for using the installation instrument are also provided.

12. A method of installation of an orthopedic brace in an animal subject, comprising:
-
placing first and second anchors mounted on first and second anchor extensions, respectively, in first and second bony parts of the body; mounting a brace inserter of an installation instrument on the first and second anchor extensions, the installation instrument having a pivot axis relative to the anchors; swinging the brace inserter relative to the anchors about the pivot axis and thereby moving the brace through an arc centered on the pivot axis of the instrument; and introducing an end of the brace to the location of the anchors. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
