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.

Claim (Index 17):
A surgical method for installing a bone anchor system for spinal fixation, comprising:\n (i) selecting each of:\n two or more bone anchors, at least one of which bone anchors is a length adjustable modular anchor system according to  claim 1 ; \n at least one spinal rod defining a longitudinal axis;\n two or more retaining housings for engaging and securing a bone anchor and a surgical rod; \n two or more locking elements for securing a rod to a bone anchor; and \n optionally, one or more compression washers for engagement between a rod and a bone anchor; \n (ii) either before or after seating the neck assembly in a retaining housing, assembling a length adjustable modular screw system, comprising the steps of:\n (a) engaging the expander and collet components of the neck assembly into one of open and mated engagement, and inserting the neck assembly into the shank socket, \n (b) contacting the distal tip of the shank with a bone, \n (c) with a suitable driver, engaging the drive recess of the neck assembly to compress the expander and collet components and splay the collet, \n (d) under continued compression, driving the threaded portion of the shank into a bone, \n (e) releasing the drive compression on the drive recess of the neck assembly, \n (e) either before or after provisionally securing a surgical rod into the retaining housing, optionally, adjusting the length of the length adjustable modular anchor system by sliding the neck assembly along the common axis within the socket; \n (f) tightening the fixation element within the retaining housing to compress the rod against the neck assembly and to drive the expander component and the collet component into compressed engagement to splay the collet within the shank socket.
