Purpose: Percutaneous epidural neuroplasty (PEN) is a minimally invasive treatment. The efficacy of PEN has been relatively well investigated; however, the relationshipbetween the clinical effectiveness of PEN and the severity of spinal canal stenosis by disc material has not yet been established. The purpose of this study was to compare clinical outcomes of PEN according to the dural sac cross-sectionalarea in single level disc disease. Materials and Methods: This study included 363 patients with back pain from single level disc disease with and without radiculopathy. Patients were categorized into groups according to spinal canal compromiseby disc material: Category 1, less or more than 50%; and Category 2, three subgroups with lesser than a third, between a third and two thirds, and more than two thirds. Clinical outcomes were assessed according to the Visual Analog Scale (VAS) score for back pain and leg pain and Odom’s criteria at 1, 3, 6, 12, and 24 months after treatment. Results: The demographic data showed no difference betweengroups according to spinal canal compromise by disc material except age (older age correlated with more spinal canal compromise). The dural sac cross-sectional area did not correlate with the VAS scores for back and leg pain after PEN in single level disc disease in Groups 1 and 2. Odom’s criteria after PEN were also not different according to dural sac cross-sectional area by disc material. Conclusion: PEN is an effective procedure in treating single level lumbar disc herniationwithout affecting dural sac cross-sectional area.
