Subtle micro-motion within the spacer by patented vertical grooves produce promotes fibrous in-growth to the spacer.
l Reverse serration on top and bottom of the spacers helps to stabilize the spacer from forward or backward migration.
l Rectangular spiral geometry balances the loading stress from the vertebral body to the spacer.
l Anatomic design on top and bottom of the spacer restores normal lordotic curve of the lumbar spine.
l Aggressive curettage of the endplates is not required in achieving optimal endplate support.
l PORNET advantage creates accelerated in-growth of cancellous bone into the spacers.
