Abstract: Apparatus and method if using a modular spinal implant system for use between adjacent vertebrae near vascular anatomy. The system includes an implant configured the fit between adjacent vertebrae, the implant having annular side walls with upper and lower surfaces configured to enclose a hollow interior, and an attachment plate rotatably coupled to the implant and configured to rotate to variable orientations relative to the implant to avoid the vascular anatomy, the attachment plate having a superior portion that is narrower than an inferior portion, the attachment plate having at least one vertebra attachment hole configured for attaching to at least one adjacent vertebrae using one or more bone screws.
