Anterior Bone Loss after Cervical Baguera C Disc versus Bryan Disc Arthroplasty

Figure 5

The key difference between Baguera C Discs and Bryan Discs. Bryan Discs have perpendicular, punched flanges which prevent posterior displacement of the device into the spinal canal. In contrast, Baguera C Discs are placed deeper, with the posterior aspect of the shell parallel to the posterior aspect of the vertebral body. Also, note the evenly distributed loading force in the neutral position.
