Rod bending is problematic. It weakens a rod. It takes time. It is hard to implant. And worst of all, it applies unintended stresses to the spine that cause pain and often lead to implant failure.
PressON totally eliminates rod bending. PressON’s novel design makes for a lower-profile construct that is stronger than traditional tulip-to-rod interfaces. But, the major advantage with PressON is that the locked construct does not impart unintended stress to the spine.
PressON simplifies the surgical procedure by use of a mobile device app that automatically calculates the ideal construct from a sagittal x-ray. The surgeon can then simply apply the suggested constructed to the spine.
