Clinical Significance of Radiologic Improvement Following Single-Level Oblique Lateral Interbody Fusion With Percutaneous Pedicle Screw Fixation.

Clinical Significance of Radiologic Improvement Following Single-Level Oblique Lateral Interbody Fusion With Percutaneous Pedicle Screw Fixation. Orthopedics. 2020 Jun 04;:1-8 Authors: Chang SY, Nam Y, Lee J, Chang BS, Lee CK, Kim H Abstract Indirect decompression using oblique lateral interbody fusion (OLIF) improves spinal canal dimensions by reducing spondylolisthesis and restoring intervertebral disk height in patients with degenerative lumbar diseases. However, the clinical significance of these radiological improvements has not been fully evaluated in the literature. To examine the relationship between the clinical and radiological outcomes following OLIF, the authors prospectively studied 41 patients who underwent single-level OLIF with percutaneous pedicle screw fixation for lumbar degenerative disease, including degenerative and spondylolytic spondylolisthesis and spinal stenosis with disk height loss. Clinical scores were obtained preoperatively and at 1 year postoperatively using multiple questionnaires. Radiological outcomes were evaluated using plain radiographs, computed tomography (CT) scans, and magnetic resonance imaging (MRI) at 1 year postoperatively. Following a single-level OLIF, all categories of clinical scores showed statistically significant improvement. Rate of cage subsidence was 14.6% and 31.7% at 1 week and 1 year postoperatively, respectively. Patients with subsidence had higher Oswestry Disability Index...
