Stress nephograms of pars interarticularis in Model B, C, D, and E under six motion states. (A–D) The stress distribution of Model B’s pars interarticularis under flexion, extension, LAR, and LLB, respectively. (E–H) The stress distribution of Model C’s pars interarticularis under flexion, extension, LAR, and LLB, respectively. (I–L) The stress distribution of Model D’s pars interarticularis under flexion, extension, LAR, and LLB, respectively. (M–P) The stress distribution of Model E’s pars interarticularis under flexion, extension, LAR, RAR, LLB, and RLB, respectively.
