Abstract OBJECTIVE We investigated facet joint angle at the level of the nucleus pulposus in herniated disks and documented the importance of this angle in preserving articulation and surgical view in patients undergoing lumbar microdiscectomy. METHODS In this prospective study using pre- and postoperative magnetic resonance imaging scans, two blinded radiologists measured and inspected the facet joint angles in 168 patients. Patients were treated with single-level, unilateral, lumbar microdiscectomy. Postoperatively, patients were divided into two groups according to whether or not any portion of the facet joint had been violated during surgery. Using the magnetic resonance imaging scans, the angles of the facet joints were measured and then correlated with whether or not the facet joint was preserved. RESULTS The follow-up period for this study was 6 months. Postoperative radicular and back pain during the follow-up period and the need for opioids in the early postsurgery period (48 h) were higher in the nonpreserved group, but these differences were not statistically significant (P > 0.05). If the facet joint angle at the disc was lower than 35 degrees in the horizontal plane, articulation cannot be preserved. However, if this angle is greater than 35 degrees, articulation may be preserved and the surgical view is satisfactory for lumbar microdiscectomy. CONCLUSION The angle of the lumbar facet joint is important to protect articulation during lumbar microdiscectomy, and violating the facet joint may affect early postoperative pain. A facet angle of less than 35 degrees does not allow for a safe surgical corridor in which to use instruments, nor does it provide a satisfactory view for the surgeon.

Introduction: Facet joint arthropathy is one of the myriad of abnormalities for low back pain and since conventional Magnetic resonance Imaging detects the facet joint pathologies poorly when compared to fat suppressed MRI sequences, fat suppressed MRI promises to be contributory to proper diagnosis and management. Objective: The objective of this study was to find the prevalence of lumbar facet joint arthrosis among patients with low back pain and comparing conventional versus fat saturated sequence in detecting the MRI findings of facet joint arthrosis. Methodology: A cross sectional study was conducted at the Department of Radiodiagnosis and Department of Orthopedics at Birat Medical College Teaching Hospital from February 15, 2020 to May 15, 2020. Ethical clearance was taken and 100 participants having low back pain were enrolled for Magnetic Resonance imaging after informed consent. Data were Results: 57% study participants were found to have facet joint arthrosis (FJA) in their lumbar spine and on comparing the detection rate of the grades of arthrosis between the conventional and FS MRI, the difference in diagnosis of grade 2 and grade 3 changes of FJA were 87.9% and 42.9% respectively whereas no difference was found in diagnosing grade 4 changes in both the sequences. Data was entered in MS excel and analysed by SPSS. Conclusion: This study showed that facet joint arthrosis is frequently seen in the patients presenting with low back pain and these changes are better diagnosed by fat saturated MRI sequence as compared to conventional sequence.
