Chondroid metaplasia of paraspinal connective tissue in the degenerative spine Hasselt University
A 51-year-old male was routinely biopsied during a paraspinal muscle study. The biopsy sample was taken from the right erector spinae muscle at the fourth lumbar vertebra. The patient had no history of (diagnosed) major back trauma. The obtained sample was histologically analyzed (hematoxylin and eosin, safranin O), and complementary magnetic resonance imaging was performed. The biopsied sample contained chondroid tissue. Based on its location, ...
Ephedrine and phenylephrine induce opposite changes in cerebral and paraspinal tissue oxygen saturation, measured with near-infrared spectroscopy : a randomized controlled trial Ghent University
While the effects of phenylephrine (PE) and ephedrine (E) on cerebral oxygen saturation (rS(c)O(2)) already has been studied, the effect on paraspinal oxygen saturation (rS(ps)O(2)) is still unexplored. This study aims to assess the effect of PE and E on rS(c)O(2) and rS(ps)O(2), measured with near-infrared spectroscopy. A randomized 4-treatment cross-over trial was designed in 28 patients under BIS-titrated anaesthesia with sevoflurane. If MAP ...
Individual fascicles of the paraspinal muscles are activated by discrete cortical networks in humans Ghent University
Vertebral level specific modulation of paraspinal muscle activity based on vestibular signals during walking KU Leuven
Evoking muscle responses by electrical vestibular stimulation (EVS) may help to understand the contribution of the vestibular system to postural control. Although paraspinal muscles play a role in postural stability, the vestibulo-muscular coupling of these muscles during walking has rarely been studied. This study aimed to investigate how vestibular signals affect paraspinal muscle activity at different vertebral levels during walking with ...
An Acute Paraspinal Compartment Syndrome Anatomic Description of the Compartment and Surgical Technique KU Leuven
An acute paraspinal compartment syndrome (CS) is a rare condition and is only described in a few case reports. In our spine surgery department, a 16-year-old boy with severe low back pain due to a lumbar paraspinal CS. was treated with a paraspinal fasciotomy. After this case, we performed a cadaver study to determinate the compartment. The objective of this paper is to give a description of the anatomic lumbar paraspinal compartment and our ...
Standardizing nomenclature in regional anesthesia: an ASRA-ESRA Delphi consensus study of abdominal wall, paraspinal, and chest wall blocks KU Leuven University of Antwerp
BACKGROUND: There is heterogeneity in the names and anatomical descriptions of regional anesthetic techniques. This may have adverse consequences on education, research, and implementation into clinical practice. We aimed to produce standardized nomenclature for abdominal wall, paraspinal, and chest wall regional anesthetic techniques. METHODS: We conducted an international consensus study involving experts using a three-round Delphi method to ...
MRI of Paraspinal Gossypiboma: Look for the Barium Sulfate Filament Hasselt University
Gossypiboma is a rare post-surgical complication comprising a retained surgical gauze surrounded by a foreign body reaction. Although usually presenting on magnetic resonance imaging (MRI) with low T1 signal, high central and low peripheral signal on T2, and bandlike peripheral enhancement, MR appearance is often non-specific. The barium sulphate filament within a surgical gauze presents on MR as a curvilinear thread which is dark on both T1 and ...
Excruciating Low Back Pain After Strenuous Exertion: Beware of Lumbar Paraspinal Compartment Syndrome KU Leuven
Low back pain is extremely common and usually a minor self-limiting condition. Rarely, however, it is a harbinger of serious medical illness. Paraspinal compartment syndrome is a rare condition, but its timely recognition is important to allow adequate treatment.
