Table 2 Comparative analysis of fusion rate of Grafton® and DBX® DBMs/local autograft composites at 12 and 24 months after instrumented posterolateral fusion

From: Surgical outcomes of two kinds of demineralized bone matrix putties/local autograft composites in instrumented posterolateral lumbar fusion

  Fusion Rate (%) P-value
  Grafton® side (n = 27) DBX® side (n = 27)  
Postoperative 12 months 59.5% (16/27) 51.9% (14/27) P = 0.425
Postoperative 24 months 70.4% (19/27) 66.7% (18/27) P = 0.574
