SUSTAIN® Large is a trapezoidal thoracolumbar vertebral body replacement device, available in both PEEK radiolucent polymer and titanium, designed for an optimal fit while maximizing both surface area and graft volume. The expulsion resistant surfaces are contoured at an 8° lordotic angle to maximize contact area and help restore the natural curvature of the spine. The implants are available in titanium or radiolucent polymer (PEEK) to allow radiographic visualization of fusion. Trapezoidal footprint: Designed with 8° of lordosis to maximize contact area and help restore the natural curvature of the spine. Three approach options: Accommodates various surgical techniques Visualization options: PEEK radiolucent material and open cross-sections in the titanium design allow radiographic visualization of fusion
