Posterior Transpedicular Dynamic Stabilization versus Total Disc Replacement in the Treatment of Lumbar Painful Degenerative Disc Disease: A Comparison of Clinical Results
Figure 3
Lordosis of the lumbar spine (L1-S1) was measured via the angle between the lines drawn from the lower endplate of L1 and the upper endplate of S1 (LL). Additionally segmental lordosis (α) at the operation level was measured via the angle between the lines drawn from the upper and lower endplates of the vertebrae that form the operation segments.
