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 tes-ng to determine the impact of the device on disc structure and biomechanical func-on.
