The objective is to study the effects of the constant axial loading and the axial fixation on the torsional behavior of spine. A miniature pressure transducer was implanted in the porcine cadaveric thoracic and lumbar disc to measure intradiscal pressure. The physiological and mechanical methodology was evaluated under the total angle of twist not to exceed 2 degree. The Intradiscal Pressure-Angle curves showed significant difference between the constant axial loading and fixation while the difference in the Moment-Angle curves seemed too be slight. In a previous study, pressures increased with twisting in axial rotation. It is concluded from our present study that the axial fixation method gives more physically experimental condition for the intradiscal pressure measurement.
