| Background: Spondylolisthesis is characterized by the anterior displacement of one vertebra relative to the vertebra beneath it in the sagittal plane of the spine. Objective: To assess the spinopelvic parameters before and after posterior interbody fusion in patients with lumbar isthmic spondylolisthesis. Patients and Methods: This observational prospective study included twenty adult patients with isthmic spondylolisthesis subjected to posterior lumbar interbody fusion (PLIF) in Neurosurgery Department, Tanta University Hospitals. Patients were subjected to clinical assessment, radiological investigations and routine laboratory investigations. Results: Regarding the X-ray evaluation of the spinopelvic parameters, PT was significantly lower postoperatively, and during follow-up after 3 and 6 months and after 1 year, Whereas SS was significantly higher postoperatively, and during follow-up. LL was higher postoperatively, and during follow-up after 3 and 6 months and after 1 year compared to preoperative values. Conclusions: Posterior interbody fusion with the insertion of a cage and transpedicular screws in patients with lumbar isthmic spondylolisthesis led to significant improvements in spinopelvic alignment, maintenance of spinopelvic parameters, restoration of sagittal balance of the spine, satisfactory fusion rate and clinical outcome, restoration of disc space height, segmental lordosis and reduction of spondylolisthesis. | ||
