Evaluation of Outcomes of Posterior lumbar Interbody Fusion for Management of Segmental Degenerative Lumbar Canal Stenosis

Background: Lumbar degenerative disorders, such as lumbar spinal stenosis, lumbar disc herniation & lumbar degenerative instability, are prevalent crippling illnesses that occur in the elderly population. Objectives: To analyze the safety and efficacy of posterior lumbar interbody fusion (PLIF) in managing segmental degenerative lumbar canal stenosis. Patients and methods: Retrospective and prospective study on 25 cases with segmental degenerative lumbar canal stenosis. Individuals with segmental degenerative lumbar canal stenosis. This study was conducted at Al-Azhar University Hospitals and Damanhur Medical Institute Hospital. Results: Our findings showed that regarding the relation between different improvements and each other's, there were no significant variations between the three groups concerning Age, Height (cm), Weight (kg), B.M.I., L.B.P., Radicular Pain, Level of Interbody Fusion by Cage, No Post O.P. Complication, and Blood Loss (CC). There was a significant distinction amongst the three groups regarding Sex, with a significant disparity between Excellent and Good: p<0.00001, and Fair vs Good: p<0.00001. Three subjects (12%) have interbody fusion at L3-L4, 17 subjects (68%) have interbody fusion at L4-L5, and five subjects (20%) have interbody fusion at L5-S1. Conclusion: Posterior lumbar interbody fusion (PLIF) can be recommended for mono-segmental spinal stenosis, with or without segmental instability. The most notable finding in this study was that males showed significant positive correlations, and overweight showed significant negative correlations with good improvement; L4-L5 was the most common level of fixation among the subjects.
