Biomechanical Comparison between Isobar and Dynamic-Transitional Optima (DTO) Hybrid Lumbar Fixators: A Lumbosacral Finite Element and Intersegmental Motion Analysis

Figure 1

Under a “displacement-controlled” mode, the performances of (a, b) 2 hybrid and (c, d) 2 static lumbar fixation models were normalized by the corresponding degenerative conditions without implantation for comparison.
