Abstract
A system including anchors, anchor components, and anchor assemblies and subassemblies that are adapted for attachment to a bony structure of a clinical subject. For example, two or more such anchors in the form of screws may be affixed to bones, for example, vertebral structures such as the pedicle, and each anchor is connected to a stabilizer such as a surgical rod that is inserted between the anchors. The anchors and assemblies are novel in many respects owing to their modular nature and height adjustability, which in contrast to conventional systems, allows the anchors to be provided to a surgeon in modular, sub assembled and fully assembled form to enable a broad array of choices in devising the optimal plane for surgical bone fixation.
