Kesesuaian Derajat Stenosis Foramina Intervertebral Lumbalis Antara Potongan Axial dan Potongan Sagital Pada Magnetic Resonance Imaging (MRI) Vertebra Lumbal Pasie Degenerasi Vertebra Lumbalis = Compatibility the Degree of Lumbar Intervertebral Foramina Stenosis Between Axial and Sagittal Planes in Magnetic Resonance Imaging (MRI) of Lumbar Vertebrae in Patients with Lumbar Vertebra Degeneration.

Latar belakang: Low back pain (LBP) dengan atau tanpa kelainan radikulopati merupakan penyebab utama disabilitas tertinggi ke 6 di dunia. LBP dapat disebabkan oleh stenosis foramen intervertebralis (SFI) lumbal yang disebabkan oleh proses degenerasi vertebra lumbal. Penilaian derajat SFI lumbal saat ini masih menggunakan potongan sagital, namun belum terdapat penilaian derajat SFI lumbal menggunakan potongan aksial Metode: Penelitian observasional analitik potong lintang menggunakan data sekunder; Sebanyak 54 pasien memenuhi kriteria penelitian yang telah dilakukan pemeriksaan MRI lumbal selama Januari 2023 hingga Desember 2023. Analisis kesesuaian antar 2 variabel kategorik disajikan dalam plot Kappa Cohen (R). Hasil: Kesesuaian pengukuran berdasarkan potongan axial dengan potongan sagital mempunyai nilai R sebesar 0,801; p < 0,001) menunjukan kesesuaian diagnostik yang hampir sempurna dalam menilai SFI lumbal antara potongan aksial dengan sagital dan hasil uji nonparametrik menggunakan McNemar menunjukan tidak terdapat perbedaan kemampuan diagnosis derajat SFI lumbal mengunakan potongan aksial maupun sagital dengan nilai p 0,209 (p = < 0,5). Kesimpulan: Terdapat kesesuaian yang sangat baik antara potongan aksial dengan potongan sagital dalam menilai derajat SFI lumbal L4-5.

Background: Low back pain (LBP) with or without radiculopathy is the 6th leading cause of disability in the world. LBP can be caused by lumbar intervertebral foramen stenosis caused by the process of lumbar vertebral degeneration. Current assessment of lumbar intervertebral foramen stenosis degrees still uses sagittal planes, but there is no assessment of lumbar SFI degrees using axial planes Methods: Cross-sectional analytical observational study using secondary data; A total of 54 patients met the criteria for a lumbar MRI examination between January 2023 and December 2023. The conformity analysis among 2 categorical variables is presented in Cohen's Kappa plot (R). Results: The suitability of measurements based on axial planes to sagittal planes has an R value of 0.801; p < 0.001) showed a near-perfect diagnostic fit in assessing lumbar SFI between axial and sagittal pieces and nonparametric test results using McNemar showed no difference in the ability to diagnose lumbar SFI degrees using axial and sagittal planes with a p value of 0.209 (p = < 0.5) Conclusion: There is an excellent fit between axial and sagittal planes in assessing grade of lumbar lumbar intervertebral foramen stenosis L4-5
