SYSTEM AND METHOD FOR VERTEBRAL LOAD AND LOCATION SENSING

摘要

A load balance and 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 report optimal prosthetic size and placement in view of the sensed load and location parameters including optional orientation, rotation and insertion angle along a determined insert trajectory.
