Translating peripheral bladder afferent mechanosensitivity to neuronal activation within the lumbosacral spinal cord of mice.

Pain 2018 Dec 5. Epub 2018 Dec 5.

Visceral Pain Research Group, Centre for Neuroscience, College of Medicine and Public Health, Flinders University, Bedford Park, South Australia, 5042, AUSTRALIA.

Primary afferent neurons transduce distension of the bladder wall into action potentials that are relayed into the spinal cord and brain, where autonomic reflexes necessary for maintaining continence are coordinated with pathways involved in sensation. However, the relationship between spinal circuits involved with physiological and nociceptive signalling from the bladder have only been partially characterised. We used ex-vivo bladder afferent recordings to characterise mechanosensitive afferent responses to graded distension (0-60mmHg) and retrograde tracing from the bladder wall to identify central axon projections within the dorsal horn of the lumbosacral spinal cord.

Unilateral Biportal Endoscopic Spinal Surgery Using a 30° Arthroscope for L5-S1 Foraminal Decompression.

Clin Orthop Surg 2018 Dec 21;10(4):508-512. Epub 2018 Nov 21.

Department of Spine Surgery, Barun Hospital, Jinju, Korea.

Foraminal decompression using a minimally invasive technique to preserve facet joint stability and function without fusion reportedly improves the radicular symptoms in approximately 80% of patients and is considered one of the good surgical treatment choices for lumbar foraminal or extraforaminal stenosis. However, proper decompression was not possible because of the inability to access the foramen at the L5-S1 level due to prominence of the iliac crest. To overcome this challenge, endoscopy-based minimally invasive spine surgery has recently gained attention. Read More

Psoas proximal insertion as a simple and reliable landmark for numbering lumbar vertebrae on MRI of the lumbar spine.

Eur Radiol 2018 Nov 9. Epub 2018 Nov 9.

Department of Radiology, Military Teaching Hospital Clermont-Tonnerre, Rue du colonel Fonferrier, 29240, Brest Cedex 9, France.

Objective: To evaluate the value of psoas muscle proximal insertion for correct numbering of the lumbar vertebrae in MRI, in particular in case of lumbosacral transitional vertebra (LSTV).

Methods: Two radiologists assessed 477 MRI scans of the lumbar spine with a sagittal localizer sequence on the whole spine for numbering vertebrae caudally from C2. Proximal insertion of the psoas was determined as the most proximal vertebra with psoas over half of its body on coronal T2 STIR sequence. Read More
