Ultrasound-Guided Cervical Intervertebral Disc Injection Without Fluoroscopy.

J Ultrasound Med 2022 Apr 14. Epub 2022 Apr 14.

Department of Orthopedics, Nara Medical University, Kashihara, Nara, Japan.

Cervical disc degeneration commonly results in referred neck pain, which is traditionally diagnosed via fluoroscopy-guided provocative discography. Herein, we discuss three cases of neck and shoulder pain treated with cervical intradiscal injections administered under ultrasound (US) guidance. The most painful intervertebral disc was identified using the sonopalpation technique, which involved palpation while visualizing anatomical structures using US. Read More

Cre/LoxP Genetic Recombination Sustains Cartilage Anabolic Factor Expression in Hyaluronan Encapsulated MSCs Alleviates Intervertebral Disc Degeneration.

Biomedicines 2022 Feb 26;10(3). Epub 2022 Feb 26.

School of Medicine, China Medical University, Taichung 40402, Taiwan.

(1) Background: Inexplicable low back and neck pain frequently results from spinal disc degeneration with an imbalanced intervertebral disc (IVD) cell homeostasis. We hypothesize that introducing MSC expressing a sustained cartilage-anabolic factor in the IVD may stimulate the mucoid materials secreted from the IVD cells, promote the MSC's chondrogenesis and maintain the hydration content providing mechanical strength to decelerate the disc degeneration progression; (2) Methods: This study expressed a cartilage-anabolic factor runx1 by a baculoviral vector (BV) transduced MSCs through a Cre/LoxP gene editing and recombination system for sustained recombinant runx1 transcription factor production. The Cre/LoxP BV modified MSCs were encapsulated by hyaluronan hydrogel, due to its' vital composition in ECM of a healthy disc and transplanted to a punctured coccygeal disc in rats through micro-injection, followed by X-ray radiography and histological analysis at the 4- and 12-weeks post-transplantation; (3) Results: Data reveals the Cre/LoxP BV system-mediated long-termed runx1 gene expression, possessing good biosafety characteristics in the in vitro cell transduction and in vivo MSCs transplantation, and maintained superior hydration content in the disc than that of mock transduced MSCs; (4) Conclusions: This proof-of-concept study fulfills the need of implanting therapeutic cells accompanied with microinjection in the disc, such as a discography and paves a road to manufacture composite hyaluronan, such as peptide modified hyaluronan as an MSC carrier for IVD regeneration in the future study.

Intervertebral disc degeneration often is a cause of low back pain (LBP) and radicular pain even without severe compression of the nerve root by hernial material. Thermodiscoplasty, or intradiscal electrothermal therapy (IDET) is used for minimally invasive treatment of discogenic pain. Pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) is used as an interventional method for radicular pain elimination. Read More

Interpretation of Morphological Details of Nondegenerated Lumbar Intervertebral Discs on Magnetic Resonance Imaging: Insights From a Comparison Between Computed Tomography Discograms and Magnetic Resonance Imaging.

J Comput Assist Tomogr 2022 May-Jun 01;46(3):487-491. Epub 2022 Mar 14.

From the Mallinckrodt Institute of Radiology, Washington University in Saint Louis, Saint Louis, MO.

Objective: To gain better insight into the magnetic resonance imaging (MRI) appearance of morphological intervertebral disc (IVD) details, such as annular and nucleus pulposus dimensions, by comparing contemporaneously obtained MRI and postdiscogram computed tomography (CT) scans of nondegenerated IVDs.

Methods: Axial T2-weighted images and same-day postdiscography CTs, acquired after the MRI, of 26 normal-appearing lumbar IVDs (control IVDs at discography) were compared. The location and extent of central hyperintense zone on MRI and the extent of contrast distribution on CT relative to the IVD width (in anteroposterior [AP] and lateral planes) were assessed, with difference in measures between the modalities used to provide apparent inner annulus thickness and to estimate dimensions of also the outer annulus and location of nucleus pulposus.

Department of Orthopedics, Institute of Biomedical Sciences, Tokushima University Graduate School, Tokushima, Tokushima, Japan.

Discal cysts are rare intraspinal extradural cysts that communicate with the corresponding intervertebral discs, and the diagnosis is difficult to distinguish from other causes of low back pain and radiculopathy. Optimal management for this type of cyst has not been determined because of its rarity. Here, we report successful treatment of a discal cyst and lumbar disc herniation using full endoscopic surgery in a professional baseball player with a chief complaint of weakness in his left lower leg.

Department of Anesthesiology, University of Kansas Medical Center, 3901 Rainbow Boulevard, Kansas City, KS 66160, USA.

Neck and back pain is increasingly prevalent, and has increased exponentially in recent years. As more resources are dedicated to the diagnosis of pain conditions, it is increasingly important that the diagnostic techniques used are as precise and accurate as possible. Traditional diagnostic methods rely heavily upon patient history and physical examination to determine the most appropriate treatments and/or imaging studies. Read More

Identification of potentially painful disc fissures in magnetic resonance images using machine-learning modelling.

Eur Spine J 2021 Dec 2. Epub 2021 Dec 2.

Departmetn of Orthopaedics, Sahlgrenska University Hospital, Gothenburg, Sweden.

Purpose: It is suggested that non-specific low back pain (LBP) can be related to nerve ingrowth along granulation tissue in disc fissures, extending into the outer layers of the annulus fibrosus. Present study aimed to investigate if machine-learning modelling of magnetic resonance imaging (MRI) data can classify such fissures as well as pain, provoked by discography, with plausible accuracy and precision.

Methods: The study was based on previously collected data from 30 LBP patients (age = 26-64 years, 11 males). Read More

Korean J Pain 2021 Oct;34(4):447-453

Department of Neurosurgery, All India Institute of Medical Science, Bhopal, India.

Background: Provocative discography (PD) is a test that is useful in diagnosing discogenic pain (DP). In this study, to diagnose DP, we used a posterolateral approach of needle placement and followed pressure criteria laid down by the Spine Intervention Society.

Department of Biomedical Sciences, Cedars-Sinai Medical Center, Los Angeles, CA, 90048, USA.

Low back pain (LBP) is often a result of a degenerative process in the intervertebral disc. The precise origin of discogenic pain is diagnosed by the invasive procedure of provocative discography (PD). Previously, we developed quantitative chemical exchange saturation transfer (qCEST) magnetic resonance imaging (MRI) to detect pH as a biomarker for discogenic pain. Read More

Autologous BMAC Therapy Improves Spinal Degenerative Joint Disease in Lower Back Pain Patients.

Front Med (Lausanne) 2021 18;8:622573. Epub 2021 Mar 18.

Canadian Centre for Regenerative Therapy, Toronto, ON, Canada.

Spinal degenerative joint disease (DJD) is associated with lower back pain (LBP) arising from the degeneration of intervertebral discs (IVD), facet joints, intertransversarii muscles, and interspinous ligaments among other anatomical structures. To circumvent the socioeconomic burdens and often-problematic surgical options imposed by DJD therapy, cell-based biologic modalities like bone marrow aspirate concentrate (BMAC) have been investigated in pre-clinical and clinical settings, mostly for IVD degeneration (IDD), with encouraging outcomes. In this study, we evaluated the differences in therapeutic benefits of BMAC between IVD- and facet joint-originating chronic LBP. Read More
