The Nautilus Thoracolumbar Spinal System is used to treat lumbar and thoracic spine issues. The implants are made with screw angle settings that can fit into a typical patient's body. The screw thread also makes it easier for the item to be inserted into the body. The friction head is also made to keep the body secure as the rod is placed inside the setup. The locking cap also keeps cross threading from being a burden as needed.
