Abstract
Apparatus and instruments for percutaneously extending an existing spinal construct ipsilaterally with an additional spinal construct in a patient are disclosed. The additional spinal construct comprises a rod connector that includes an elongate additional rod integrally attached thereto. The additional rod is placed through an access port in a first orientation generally parallel to the longitudinal axis of the access port and rotated to a different second orientation generally transverse to the longitudinal axis of the access port. During such rotation the additional rod is moved subcutaneously beneath the skin of the patient from the existing spinal rod to an additional bone engaging implant. In another arrangement, the extension of an existing spinal construct in a minimally invasive procedure comprises a rod connector having an offset support for receiving an additional spinal rod that may be placed laterally interiorly or exteriorly of the existing spinal construct.
