Abstract
A modular apparatus for extending a rod in an existing spinal construct comprises a modular rod connector for attachment to the existing rod and a modular rod extender that may be selectively attached to the rod connector. Each rod connector includes a spherical head that is formed to have the same size and configuration such that any selected modular rod extender may be attached to a selected rod connector. Each rod connector comprises an attachment portion having an opening for receipt of a portion of the rod of an existing spinal construct. Each modular rod extender comprises an extender body including a common modular attachment feature at one end for receipt of the spherical head of the selected rod connector, and an extension rod extending from an opposite end to extend the existing spinal rod.
