Convention: Rotation at each site is measured with respect to a horizontal line.
Rotation of a bone is then taken as rotation of distal end with respect to proximal end
(similar to displacement in fracture description), as in the example below.

This calculator is experimental and MAY NOT WORK AT ALL.
Making diagnostic or treatment decisions based on its output could be risky.
