Pathophysiology and biomechanics of the aging spine.

Author information

2 Orthopaedic Clinic, University of Athens, Greece.


AGING OF THE SPINE IS CHARACTERIZED BY TWO PARALLEL BUT INDEPENDENT PROCESSES: the reduction of bone mineral density and the development of degenerative changes. The combination of degeneration and bone mass reduction contribute, to a different degree, to the development of a variety of lesions. This results in a number of painful and often debilitating disorders. The present review constitutes a synopsis of the pathophysiological processes that take place in the aging spine as well as of the consequences these changes have on the biomechanics of the spine. The authors hope to present a thorough yet brief overview of the process of aging of the human spine.
