Abstract
A spine alignment system is provided to assess load forces on the vertebra in conjunction with overall spinal alignment. The system includes a spine instrument having an electronic assembly and a sensorized head. The sensorized head can be inserted between vertebra and report vertebral conditions such as force, pressure, orientation and edge loading. A GUI is therewith provided to show where the spine instrument is positioned relative to vertebral bodies as the instrument is placed in the inter-vetebral space. The system can distract vertebrae to a first height and measure the load applied by the spine region. The GUI can indicate that the load is outside a predetermined range. The spine region can be distracted to a second height where the load is measured within the predetermined load range.
