Weight-bearing MRI of the Lumbar Spine: Spinal Stenosis and Spondylolisthesis.

Semin Musculoskelet Radiol 2019 Dec 19;23(6):621-633. Epub 2019 Nov 19.

Department of Rheumatology, The Parker Institute, Copenhagen University Hospital, Bispebjerg and Frederiksberg, Copenhagen, Denmark.

Symptoms of degenerative lumbar spinal stenosis include back pain, radiculopathy, claudication, and muscular fatigue that tend to be predominant in the standing position or during walking. Lumbar spondylolisthesis is also a well-known cause of spinal stenosis, lateral recess, and neural foraminal narrowing that tends to become more severe in the upright position. This indicates a functional positional component of both spinal stenosis and spondylolisthesis. Read More

World Neurosurg 2020 Feb 4;134:137-140. Epub 2019 Nov 4.

Department of Neurosurgery, Ulsan University Hospital, University of Ulsan College of Medicine, Dong-gu, Ulsan, Korea. Electronic address:

Background: Oblique lumbar interbody fusion (OLIF) is a surgical technique for lumbar interbody fusion that allows surgeons to use a large cage while preserving the spine muscles. The surgical corridor of OLIF is close to the ureter in the retroperitoneal space and therefore entails a potential for injury to this organ. Although there are some published cases of ureteral injury that were identified during OLIF, to our knowledge, there have been no reports about delayed ureteral strictures and kidney atrophy after OLIF.

Is age more than manual material handling associated with lumbar vertebral body and disc changes? A cross-sectional multicentre MRI study.

BMJ Open 2019 09 18;9(9):e029657. Epub 2019 Sep 18.

Department of Medical and Surgical Sciences, University of Bologna, Bologna, Italy.

Objective: Conflicting evidence exists to what extent manual material handling (MMH) causes lumbar disc disease, lack of evidence exist that this effect takes place especially at L5-S1 level, where the greatest moment occurs. The aim was to assess if lumbar vertebral body and disc changes are more common in people whose job involves significant MMH and, if so, to evaluate if lumbar vertebral body and disc changes are more prevalent in the lower part of the lumbar spine (L4-L5 and L5-S1).

Design: Observational, cross-sectional, with quasi-random recruitment. Read More

Development of Upright Computed Tomography With Area Detector for Whole-Body Scans: Phantom Study, Efficacy on Workflow, Effect of Gravity on Human Body, and Potential Clinical Impact.

Invest Radiol 2020 02;55(2):73-83

From the Departments of Diagnostic Radiology.

Objectives: Multiple human systems are greatly affected by gravity, and many disease symptoms are altered by posture. However, the overall anatomical structure and pathophysiology of the human body while standing has not been thoroughly analyzed due to the limitations of various upright imaging modalities, such as low spatial resolution, low contrast resolution, limited scan range, or long examination time. Recently, we developed an upright computed tomography (CT), which enables whole-torso cross-sectional scanning with 3-dimensional acquisition within 15 seconds. Read More

The analysis of percutaneous pedicle screw technique with guide wire-less in lateral decubitus position following extreme lateral interbody fusion.

J Orthop Surg Res 2019 Sep 5;14(1):304. Epub 2019 Sep 5.

Department of Orthopaedic Surgery, Surgical Science, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa, 259-1193, Japan.

Background: Lateral lumbar interbody fusion (LLIF) and bilateral percutaneous pedicle fixation are valuable, minimally invasive lateral approaches used to treat symptomatic degenerative disc disease. In the current procedure, the patient's position on the operating table is changed after LLIF surgery from the lateral decubitus to the prone position. The ability to perform both approaches with the patient in the same position should reduce operation time. Read More
