ISSLS PRIZE in Clinical Science 2023: comparison of degenerative MRI features of the intervertebral disc between those with and without chronic low back pain. An exploratory study of two large female populations using automated annotation
A. Jamaludin, T. Kadir, A. Zisserman, I. McCall, F. M. K. Williams, H. Lang, E. Buchanan, J. P. G. Urban & J. C. T. Fairbank
doi : 10.1007/s00586-023-07604-9
The relationship of degeneration to symptoms has been questioned. MRI detects apparently similar disc degeneration and degenerative changes in subjects both with and without back pain. We aimed to overcome these problems by re-annotating MRIs from asymptomatic and symptomatics groups onto the same grading system.
ISSLS Prize in Bioengineering Science 2023: Age- and sex-related differences in lumbar intervertebral disc degeneration between patients with chronic low back pain and asymptomatic controls
Noah B. Bonnheim, Ann A. Lazar, Anika Kumar, Zehra Akkaya, Jiamin Zhou, Xiaojie Guo, Conor O’Neill, Thomas M. Link, Jeffrey C. Lotz, Roland Krug & Aaron J. Fields
doi : 10.1007/s00586-023-07542-6
Clinical management of disc degeneration in patients with chronic low back pain (cLBP) is hampered by the challenge of distinguishing pathologic changes relating to pain from physiologic changes related to aging. The goal of this study was to use imaging biomarkers of disc biochemical composition to distinguish degenerative changes associated with cLBP from normal aging.

Murat Şakir Ekşi, Ömer Orhun, Yaren Nur Demir, Müjdat Kara, Gürkan Berikol & Emel Ece Özcan-Ekşi
doi : 10.1007/s00586-023-07673-w
Low back pain (LBP) impairs the quality of life and rises healthcare costs. The association of spine degeneration and LBP with metabolic disorders have been reported, previously. However, metabolic processes related with spine degeneration remained unclear. We aimed to analyze whether serum thyroid hormones, parathormone, calcium, and vitamin D levels were associated with lumbar intervertebral disc degeneration (IVDD), Modic changes, and fatty infiltration in the paraspinal muscles.
Treatment of acute traumatic central cord syndrome: a score-based approach based on the literature
A. Aravin Kumar, Wong Joey Ying Hao, Robin Pillay, Colum Patrick Nolan & Ling Ji Min
doi : 10.1007/s00586-023-07626-3
Acute traumatic central cord syndrome (ATCCS) accounts for up to 70% of incomplete spinal cord injuries, and modern improvements in surgical and anaesthetic techniques have given surgeons more treatment options for the ATCCS patient. We present a literature review of ATCCS, with the aim of elucidating the best treatment option for the varying ATCCS patient characteristics and profiles. We aim to synthesise the available literature into a simple-to-use format to aid in the decision-making process.

Lisa Oezel, Ichiro Okano, Conor Jones, Stephan N. Salzmann, Jennifer Shue, Dominik Adl Amini, Manuel Moser, Erika Chiapparelli, Andrew A. Sama, John A. Carrino, Frank P. Cammisa, Federico P. Girardi & Alexander P. Hughes
doi : 10.1007/s00586-023-07570-2
The vertebral bone quality (VBQ) score based on magnetic resonance imaging (MRI) was introduced as a bone quality marker in the lumbar spine. Prior studies showed that it could be utilized as a predictor of osteoporotic fracture or complications after instrumented spine surgery. The objective of this study was to evaluate the correlation between VBQ scores and bone mineral density (BMD) measured by quantitative computer tomography (QCT) in the cervical spine.

Rodrigo Amaral, Gabriel Pokorny, Fernando Marcelino, Rafael Moriguchi, Jullyene Pokorny, Igor Barreira, Weby Mizael, Marcelo Yozo, Sebastião Fragoso & Luiz Pimenta
doi : 10.1007/s00586-023-07619-2
The lateral lumbar interbody fusion arose as a revolutionary approach to treating several spinal pathologies because the techniques were able to promote indirect decompression and lordosis restoration through a minimally invasive approach allowing for reduced blood loss and early recovery for patients. However, it is still not clear how the technique compares to other established approaches for treating spinal degenerative diseases, such as TLIF, PLIF, and PLF.
Bone collagen quality in lumbar fusion patients: the association between volumetric bone mineral density and advanced glycation endproducts
Henryk Haffer, Erika Chiapparelli, Maximilian Muellner, Manuel Moser, Yusuke Dodo, Marie-Jacqueline Reisener, Dominik Adl Amini, Stephan N. Salzmann, Jiaqi Zhu, Yi Xin Han, Eve Donnelly, Jennifer Shue, Andrew A. Sama, Frank P. Cammisa, Federico P. Girardi & Alexander P. Hughes
doi : 10.1007/s00586-023-07589-5
The sole determination of volumetric bone mineral density (vBMD) is insufficient to evaluate overall bone integrity. The accumulation of advanced glycation endproducts (AGEs) stiffens and embrittles collagen fibers. Despite the important role of AGEs in bone aging, the relationship between AGEs and vBMD is poorly understood. We hypothesized that an accumulation of AGEs, a marker of impaired bone quality, is related to decreased vBMD.

Early cement augmentation may be a good treatment option for pain relief for osteoporotic compression fractures: a systematic review and meta-analysis
Shawn JS Seah, Mark HX Yeo, Jun-Hao Tan & Hwee Weng Dennis Hey
doi : 10.1007/s00586-023-07658-9
The incidence of osteoporotic compression fractures (VCFs) have been rising over the past decades. Presently, vertebral cement augmentation procedures such as balloon kyphoplasty and vertebroplasty are common treatments allowing pain relief and functional recovery. However, there is controversy on whether different timeframes for cement augmentation affects clinical outcomes. Hence, this study aimed to compare pain relief and complication rates between early versus late cement augmentation.

Max Prost, Melanie Elisabeth Röckner, Roman Taday, Joachim Windolf & Markus Rafael Konieczny
doi : 10.1007/s00586-023-07659-8
There is no data that shows if it is possible to determine if a curve is structural or non-structural or to assess flexibility of an adolescent idiopathic scoliosis (AIS) by magnetic resonance imaging (MRI) instead of bending radiographs (BR). We investigated if the results of BR may be compared to those of MRI.

A prospective study to identify preoperative serum parameters for spinal implant infection detected by sonication fluid culture
Daniel GarcÃa-Pérez, Guillermo GarcÃa-Posadas, Rafael San-Juan, Patricia Brañas, Irene Panero-Pérez, Juan Delgado-Fernández & Igor Paredes
doi : 10.1007/s00586-023-07628-1
Low-virulent microorganisms identified on pedicle screws by sonication fluid culture (SFC) are an important cause of implant loosening. While sonication of explanted material improves the detection rate, the risk of contamination exists and no standardized diagnostic criteria for chronic low-grade spinal implant-related infection (CLGSII) are stablished. Besides, the role of serum C-reactive protein (CRP) and procalcitonin (PCT) in CLGSII has not been adequately investigated.
