BACKGROUND CONTEXT Magnetic resonance imaging (MRI) is commonly used to assess patients with lumbar spinal stenosis. No single MRI sequence has been shown to be superior in spinal canal measurements. There are also cost concerns for the increased clinical and research use of MRI. Using only a single sequence may lower the financial burden; however, this requires spinal canal measurements in bot...

INTRODUCTION Accurate morphometric characterization of the lumbar spinal canal is important in understanding low back disorders such as lumbar spinal stenosis. Current conventional methods measuring the AP diameter of the canal, a common parameter for defining the canal, use practical and clinically available methods where patient CT scans are analyzed in 2D. This method, however, does not take...

Background & Aim: Lumbosacral pain is extremely common as age increases. Spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. This study aimed at studying the frequency of instrumentation in patients referring to our center. Methods & Materials/Patients: This retrospective cross-sectional study included 1200 patients with low back and...

In 1934 Mixter and Barr described the syndrome of the ruptured intervertebral disc in the lumbar region. Since then the herniated intervertebral disc has been considered to be the dominant cause of low back pain and sciatica. In 1953 Schlesinger and Taveras pointed out that in the presence of a narrow spinal canal patients with herniated intervertebral discs may present an atypical picture of m...
