Purpose To determine the repeatability of magnetic resonance (MR) elastography-derived shear stiffness measurements of the intervertebral disc (IVD) taken throughout the day and their relationship with IVD degeneration and subject age. Materials and Methods In a cross-sectional study, in vivo lumbar MR elastography was performed once in the morning and once in the afternoon in 47 subjects witho...
STUDY DESIGN Cultured annulus fibrosus cells within an atelocollagen honeycomb-shaped scaffold with a membrane seal were allografted into the lacunas of intervertebral discs of which the nucleus pulposus had been vaporized using an indocyanine green dye-enhanced laser. Regeneration of the intervertebral disc was assessed based on the viability and histologic status of the allografted annulus fi...
Herniated nucleus pulposus (HNP) is a common disease that induces back pain and radicular pain. Some cases require surgical treatment due to persistent severe pain. However, in some cases, pain can be relieved with conservative treatment or at times relived spontaneously. Therefore, the most effective treatment method for HNP is undefinable. Spontaneous regression of HNP has been recognized wit...
BACKGROUND CONTEXT The intervertebral disc is a common source of low back pain (LBP). Prospective studies suggest that treatments that intermittently distract the disc might be beneficial for chronic LBP. Although the potential exists for distraction therapies to affect the disc biomechanically, their effect on intradiscal stress is debated. PURPOSE To determine if distraction alone, distract...
Introduction: The aim of this study was to study if lidocaine exhibits a toxic effect on bovine-derived nucleus pulposus (NP) cells in an in vitro study. Provocative discography is utilized by some physicians in the evaluation of back pain that may be discogenic in origin, and some variations of the technique suggest infiltration of lidocaine into the outer anulus fibrosus prior to intradiscal ...
Low back pain is a crucial public health problem that commonly associated with intervertebral disc de? generation and has vast socio?economic impact worldwide. Current treatments for degeneration are conservative, non?surgical, or surgical interventions, there no current clinical therapy aimed at directly reversing the degeneration. Given limited capacity of (IVD) cells to self?repair, treatmen...
