Abstract:
1. A method of performing a revision surgery of an interbody motion preservation implant including at least two separable components, said motion preservation implant having been inserted into an intervertebral space in a patient's lumbar spine during a first anterior approach surgery, said intervertebral space defined by adjacent first and second vertebral bodies, each of said vertebral bodies having an anterior portion, a posterior portion and opposing lateral portions, said method comprising the steps of: (a) accessing said intervertebral space through a trans-psoas operative corridor established in a generally lateral direction relative to said intervertebral space; (b) completely removing all components of said intervertebral motion preservation implant from said intervertebral space through said trans-psoas operative corridor such that the entirety of said intervertebral motion preservation implant is extracted from said intervertebral space; (c) after accessing said intervertebral space through said trans-psoas operative corridor, repairing or augmenting an anterior longitudinal ligament previously altered during said first anterior approach surgery; and (d) laterally inserting a spinal fusion implant having a sidewall extending from an upper surface to a lower surface through said trans-psoas operative corridor and into said intervertebral space previously occupied by said motion preservation implant such that said sidewall extends along a full height of said intervertebral space and said upper and lower surfaces of said spinal fusion implant contact said adjacent first and second vertebral bodies.
