Objective To compare the difference in efficacy between open PLIF and UBE for lumbar
spinal stenosis and the effect on postoperative adjacent segment instability. Method The …

Magnetic resonance imaging (MRI) is the established technique for evaluating the spine.
Unfortunately, the supine position of the patient during conventional MRI scanning does not …

Study Design. Retrospective chart review Objective. To determine whether supine lateral
radiographs increase the amount of segmental instability visualized in single-level lumbar …

Study Design. Prospective cohort study in consecutive patients. Objective. To investigate
and compare the use of 2 diagnostic modalities in the evaluation of stability in lumbar …

Background Segmental instability in patients with degenerative lumbar spondylolisthesis is
an indication for surgical intervention. The most common method to evaluate segmental …

Aims To determine the effectiveness of prone traction radiographs in predicting
postoperative slip distance, slip angle, changes in disc height, and lordosis after surgery for …

The human spine is a complex biomechanical system composed of multiple articular
structures controlled by muscles. It has 2 principal crucial functions: support and protection …

Background: Diagnosing intervertebral instability is crucial for the treatment of degenerative
lumbar spondylolisthesis (DLS). Disabling back pain will reduce spinal mobility which leads …

Study Design. A retrospective cohort study of consecutive patients. Objective. To investigate
whether adequate flexion-extension was acquired in standard functional radiographs in …

Background Generally, most spine surgeons agree that increased segmental motion viewed
on flexion-extension radiographs is a reliable predictor of instability; however, these views …
