Van-e esély az intervertebralis discusok regenerációjára?

Orv Hetil 2022 May 15;163(20):789-796. Epub 2022 May 15.

1 Service d'Orthopédie et Traumatologie, Centre Hospitalier Universitaire - Brugmann, Université Libre de Bruxelles Place Van Gehuchten 4., Bruxelles 1020 Belgique.

Introduction: Segmental instability of the spine caused by the decreased height of intervertebral discs is one of the major causes of chronic low back pain affecting 70-80% of the adult population. The decrease in height is due to degenerative lesions induced by vertical compression overload of the disc.

A protocol for recruiting and analyzing the disease-oriented Russian disc degeneration study (RuDDS) biobank for functional omics studies of lumbar disc degeneration.

PLoS One 2022 13;17(5):e0267384. Epub 2022 May 13.

Novosibirsk State University, Novosibirsk, Russia.

Lumbar intervertebral disc degeneration (DD) disease is one of the main risk factors for low back pain and a leading cause of population absenteeism and disability worldwide. Despite a variety of biological studies, lumbar DD is not yet fully understood, partially because there are only few studies that use systematic and integrative approaches. This urges the need for studies that integrate different omics (including genomics and transcriptomics) measured on samples within a single cohort. Read More

Ex vivo biomechanical evaluation of Acute lumbar endplate injury and comparison to annulus fibrosus injury in a rat model.

J Mech Behav Biomed Mater 2022 Apr 14;131:105234. Epub 2022 Apr 14.

Leni and Peter W. May Department of Orthopaedics, Icahn School of Medicine at Mount Sinai, One Gustave Levy Place, Box 1188, New York, NY, 10029-6574, USA. Electronic address:

Back pain is often associated with intervertebral disc (IVD) degeneration, and IVD degeneration phenotypes are commonly characterized by annulus fibrosus (AF)-driven and endplate (EP)-driven phenotypes. Few studies of EP injury exist in animal models, even though clinical studies show EP lesions are strongly associated with IVD pathology and pain. This project established an ex-vivo rat lumbar EP injury model and characterized effects of EP injury on motion segment biomechanical properties, as compared to AF injury, a common way of inducing IVD degeneration.

Transforaminal lumbar interbody fusion with a silicon nitride cage demonstrates early radiographic fusion.

J Spine Surg 2022 Mar;8(1):29-43

Ortho Northeast, Fort Wayne, IN, USA.

Background: Degeneration of the lumbar spine is common in aging adults and reflects a significant morbidity burden in this population. In selected patients that prove unresponsive to non-surgical treatment, posterior lumbar fusion (PLF) surgery, with or without adjunctive transforaminal lumbar interbody fusion (TLIF) can relieve pain and improve function. We describe here the radiographic fusion rates for PLF versus TLIF, using an intervertebral spinal cage made of silicon nitride ceramic (chemical formula SiN). Read More

Schmorl's nodes could be associated with intervertebral disc degeneration at upper lumbar levels and end-plate disease at lower lumbar level in patients with low back pain.

J Clin Neurosci 2022 Jun 12;100:66-74. Epub 2022 Apr 12.

Bahçeşehir University, School of Medicine, Department of Physical Medicine and Rehabilitation, Istanbul, Turkey.

Schmorl's nodes (SNs) have increasingly been recognized on vertebral end-plates using advanced imaging techniques. Even though vertebral end-plates are the closest structures to discs, their pathologies are underestimated in the etiology of low back pain (LBP). We aimed to detect the prevalence of SNs and other end-plate defects in subjects with/without LBP and to understand whether SNs were associated with LBP and spinal degeneration. Read More

Optimization of a lumbar interspinous fixation device for the lumbar spine with degenerative disc disease.

PLoS One 2022 7;17(4):e0265926. Epub 2022 Apr 7.

School of Mechanical Engineering, Pusan National University, Busan, Republic of Korea (South Korea).

Interspinous spacer devices used in interspinous fixation surgery remove soft tissues in the lumbar spine, such as ligaments and muscles and may cause degenerative diseases in adjacent segments its stiffness is higher than that of the lumbar spine. Therefore, this study aimed to structurally and kinematically optimize a lumbar interspinous fixation device (LIFD) using a full lumbar finite element model that allows for minimally invasive surgery, after which the normal behavior of the lumbar spine is not affected. The proposed healthy and degenerative lumbar spine models reflect the physiological characteristics of the lumbar spine in the human body. Read More

Long-Term Clinical and Radiological Outcomes of Minimally Invasive Transforaminal Lumbar Interbody Fusion: 10-Year Follow-up Results.

J Korean Med Sci 2022 Apr 4;37(13):e105. Epub 2022 Apr 4.

Department of Orthopaedic Surgery, Soonchunhyang University Seoul Hospital, Seoul, Korea.

Background: Many studies have reported that minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) provides satisfactory treatment comparable to other fusion methods. However, in the case of MI-TLIF, there are concerns about the long-term outcome compared to conventional bilateral PLIF due to the small amount of disc removal and the lack of autogenous bone graft. Long-term follow-up studies are still lacking as most of the previous reports have follow-up periods of up to 5 years. Read More
