From: Comparison of the PEEK cage and an autologous cage made from the lumbar spinous process and laminae in posterior lumbar interbody fusion

  Group A Group B p-value
Pre-OP Post-OP Pre-OP Post-OP
L3/4 10.86 ± 3.63 18.86 ± 2.91 10.29 ± 3.30 20.00 ± 2.65 NS
L4/5 10.88 ± 3.60 19.53 ± 2.84 11.33 ± 3.09 20.50 ± 3.88 NS
L5/S1 11.67 ± 3.87 23.67 ± 2.50 12.10 ± 3.48 22.00 ± 4.77 NS
  1. Abbreviation: NS not significant
  2. Data presented as mean ± SD. P-value was compared by Student’s t-test. Significant differences existed between pre- and postoperative regional lordosis in both groups (P < 0.05); no significant difference existed between the two groups (p > 0.05)
