A spine measurement system includes at least one spinal instrument and a remote system. The spinal instrument comprises a handle, a shaft, an accelerometer, a sensored head, and an electronic assembly. The sensored head includes one or more sensors that are operatively coupled to the electronic assembly. The sensored head can be inserted between vertebra and report vertebral conditions such as force, pressure, orientation and edge loading. A GUI of remote system can report position via the accelerometer to show spinal instrument relative to vertebral bodies as the instrument is placed in the inter-vertebral 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.
