Abstract
The invention provides a connecting rod for bone anchors such as pedicle screws. The rod is constructed to include a main shaft portion that is not bioresorbable and a tip portion that is bioresorbable. The tip facilitates percutaneous insertion into a patient's body. After placement of the rod, the bioresorbable tip is resorbed preventing post-operative complications such as impingement of adjacent spinal facet joints.
