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
The aim of this study is to prospectively investigate the potential for bony fusion of ViviGen® bone graft substitute in comparison to rhBMP-2 in monosegmental ALIF procedure L5/S1 and in monosegmental XLIF procedure L4/5
⁃ Patients who have an indication for a monosegmental ALIF procedure on the L5/S1 segment or a monosegmental XLIF procedure on L4/5 (both ALIF and XLIF procedure with or without an additional pedicular stabilisation), e.g., treating conditions such as spondylosis, spondylolisthesis and degenerative disc disorders with back and/or leg pain
• Patients must be 18 - 70 years of age
• Patients must have understood and signed the study information and the informed consent form
• Patients are willing and able to complete scheduled follow-up evaluations / questionnaires as described in the Informed Consent
