Figure 4

Comparison of RoM values for five specimen groups in extension and flexion in neutral zone (NZ) and elastic zone (EZ) . Incomplete burst fracture creation (2) resulted in a significant increase in NZ and EZ, posterior bisegmental instrumentation resulted in a significant decrease of NZ and EZ (3) for flexion and extension. HA resulted in no additional primary stability (4), whereas isolated PMMA VP (5) increased fractured values, but remained significant less than prefractured values in flexion (NZ and EZ) as well as NZ in extension.
