Performance Tes-ng of an Injectable Silicone Rubber Based Nucleus Replacement Device
A novel intervertebral disc nucleus replacement device is comprised of an elas-c silicone membrane filled with liquid in situ curable silicone to form an elastomeric implant surrounding a central gas chamber that allows inward deforma-on of the cured component under load. Samples of this device were subjected to finite element analysis (FEA), digital pressure mapping and biomechanical flexibility ...

Biomechanical Flexibility Testing of an in Situ-Cured Silicone-Based Disc Nucleus Prosthesis
A new intervertebral disc nucleus replacement device having three major features has been designed, comprising: 1) a peripheral textile band, 2) a silicone membrane filled with silicone that cures in situ forming an elastomeric implant and 3) an internal chamber that allows for deformation of the cured component (Figure 1). Samples of this device were subjected to biomechanical flexibility ...

Postoperative Spinal Instability at L3-4 Revealed by Upright Weight-Bearing MRI - Case Study
The patient was scanned in the FONAR Upright MRI in early 2002, one year after her spinal fusion. Both Upright and recumbent scans were performed on her in the multi-position FONAR Upright MRI. The recumbent MRI (left image) exhibited only a normal lumbar lordotic curve and a modest bulge of the L3-4 intervertebral disc, consistent with her prior recumbent MRI scan on a conventional MRI. The ...

Finite element modeling of the full lumbar spine with an intervertebral disc nucleus replacement device
Introduction Nucleus replacement technologies are a minimally invasive treatment for degenerative tSsc disease. Nucleus replacement may better restore the natural biomechanics of the spine compared to alternative treatments. Finite element (FE) modeling can be used to determine the biomechanics associated with nucleus replacement devices. A novel nucleus replacement device was ...

Finite Element Study of a Lumbar Intervertebral Disc Nucleus Replacement Device
Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device ...

Combatting the Opioid Crisis with Cell Therapies for Chronic Back Pain
It’s no secret that opioid addiction is at an all-time high and represents a major public health threat. The CDC estimates that opioid addiction resulted in a record 72,000 drug overdose deaths in 2017 alone. What strikes me as one of the most tragic parts of this narrative is that so many of these deaths were people who became addicted to opioids after simply seeking relief ...
