INSTRUMENTATION AND ASSOCIATED TECHNIQUES FOR MINIMALLY INVASIVE SPINAL CONSTRUCT INSTALLATION

摘要

A spinal fixation installation assembly includes an elongate member having a trailing end. The elongate member, which could be a rigid member, is configured for travel in a first direction along an elongate portion of a first bone anchor coupled to a spine. The elongate member is also configured to travel in a second direction between the first bone anchor and a second bone anchor also coupled to the spine. A cord member is coupled to the trailing end of the elongate member. In one aspect of this embodiment, a spine rod is coupled to the cord member at its leading end and is configured for travel in the first and second directions. The elongate portion of one or more of the bone anchors may extend percutaneously from the spine, while the spine rod may be releasably coupled to the cord member.
