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 designed as a conforming
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 testing to determine the impact of device implantation on functional spinal unit (FSU) range of motion (

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 tes-ng to determine the impact of the device on disc structure and biomechanical func-on.
Abstract
Background Nucleus replacement devices are designed to replace the native pain-generating lumbar nucleus while preserving the annulus fibrosus, endplates, and natural motion. The DASCOR Disc Arthroplasty Device seemed to perform well clinically but was discontinued in 2009. While there are no commercially available NRDs today, the potential advantages of using such devices have prompted a renewed interest in further developing the tech
