NCT05246241

Brief Summary

There are currently no standard criteria for evaluating the risk of recurrent disk herniation following surgical repair. This study investigated the predictive values of five presurgical imaging parameters, paraspinal muscle quality, annular tear size, Modic changes, modified Pfirrmann's disc degeneration grade, and presence of sacralization or fusion. Clinical status and MRI findings were evaluated before surgery and 4, 12, and 24 months post-surgery using a Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Short Form 36 (SF36).
