This condition is naturally age-related and exacerbated by traumatic events, lifestyle factors, and individual genetic susceptibilities. Treatment for advanced disc degeneration typically involves surgery (spinal fusion) aimed at addressing and fusing the affected intervertebral discs using an interbody implant combined with a bone graft.\n\nAlthough the use of interbody implants promotes temporary fusion, long-term success largely depends on the bone substitute used, with failure rates ranging from 10 to 20% (unsuccessful fusion, persistent symptoms, need for reoperation). Historically, autologous bone grafting was the standard, but it carries disadvantages related to pain and invasiveness. Synthetic, bioactive bone substitutes are now used, although their effectiveness varies.\n\nAnimal studies support the hypothesis that a new substitute based on specific osteo-immunology technology (MagnetOs, Kuros) could offer superior results compared to autologous bone grafts and competing osteo-inductive materials, while being minimally invasive. This study aims to evaluate its properties in terms of bone fusion and its impact on functional scores in patients, hypothesizing a significant improvement in fusion rates and functional scores with this new substitute.",[72],"Disc Degeneration",[74,75,76],"spinal surgery","spinal fusion","intervertebral disc","2026-03-09",{"date":79,"type":80},"2026-03-11","ACTUAL",{"date":82,"type":80},"2026-01-28",{"date":84,"type":66},"2029-01",{"name":5,"class":6},1]
