Ventral corpectomy approach with one large strut grafts and two points of screw fixation for kyphotic deformity correction. A large strut graft without multiple points of fixation may not maintain the lordotic posture and can subside into the vertebral endplates, resulting in loss of fixation and loss of the lordotic restoration. However, multiple interbody fusions with supplemental plate fixation and multiple points of screw fixation distribute the loads over greater points of fixation, thereby reducing the risk to localized stress risers, providing improved resistance to translation, loss of lordosis, and subsidence.
