Dynamic compressive properties of human lumbar intervertebral joints: a comparison between fresh and thawed specimens.
A comparison between the dynamic compressive properties of human lumbar intervertebral joints when fresh and after a period of deep frozen storage was made. Physiologically relevant loads of -750 +/- 250 N were applied in axial compression with the joint constrained against bending, over a frequency range of 0.01-10 Hz. Frozen storage was found not to affect the compressive stiffness or hysteresis of the seven joints. The magnitude of the observed changes in mean values were small, less than 1% decrease in the compressive stiffness and less than 1% increase in hysteresis after deep frozen storage.
