Comparing two bone grafts for spine surgery outcomes

Comparison of Radiographic Fusion Rate and Clinical Outcome of Anterior Lumbar and Extreme Lateral Interbody Fusion Performed With Either Recombinant Human Bone Morphogenetic Protein-2 or ViviGen® Cellular Bone Matrix, a Prospective Randomised Assessor Blind, Monocentric Trial

NA · Lindenhofgruppe AG · NCT05238740

What this trial studies

This study aims to compare the effectiveness of two different bone graft substitutes, ViviGen® and recombinant human bone morphogenetic protein-2 (rhBMP-2), in achieving bony fusion during anterior lumbar interbody fusion (ALIF) and extreme lateral interbody fusion (XLIF) procedures. It will prospectively evaluate the radiographic fusion rates and clinical outcomes in patients undergoing these surgeries for conditions like spondylosis and degenerative disc disease. Follow-up assessments will be conducted at multiple intervals up to one year post-surgery to monitor fusion rates and patient recovery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with indications for monosegmental ALIF or XLIF procedures due to spondylosis, spondylolisthesis, or degenerative disc disease.

Not a fit: Patients with spinal tumors, trauma, known bone diseases, or those outside the age range of 18 to 70 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into more effective bone graft options for spinal fusion surgeries, potentially improving patient outcomes.

How similar studies have performed: Previous studies have shown varying success with similar bone graft substitutes, but this specific comparison is novel.
