From: Biomechanical evaluation of three surgical scenarios of posterior lumbar interbody fusion by finite element analysis

  ALL (L5-S1) PLL (L3-L4) LF (L1-L2) IL (L3-L4) ISL (L5-S1) SSL (L5-S1)
PCT 44.75% 22.16% 1.78% 31.45% 8.26% 14.35%
PAIB 44.08% 16.63% 1.93% 39.04% 67.31% 72.31%
PCP 44.44% 22.70% 1.68% 31.40% 8.75% 14.71%
  1. (Percentage change = (Data of surgical model - Data of intact model)/Data of intact model × 100%. The segments shown in the brackets were the positions that maximum change occurred.)
