An expression of the rotational angles of vertebrae which are measured by a system based on photogrammetry has been proposed by the authors. The angle is calculated as the corrective rotational angle of objective vertebrae coordinates to coincide with the reference vertebral coordinates. One of the reference vertebral coordinates can be selected as its rotational axis. Also, the axis of coordinates of the objective vertebra would be selected as its rotational axis. The former rotation is named as the other axes rotation and the latter as the self axes rotation. Two values according to the two cases in these expressions introduced a little confusion to the estimation of the rotated state of the vertebra. Then, the third expression, named the mean rotation, is proposed. By investigation of the proposed three expressions, it is concluded that the expression by mean rotation is useful for the analysis of spinal deformity.
