Normal life stressors, possibly compounded by traumatic injuries to the spinal architecture, cause degeneration in the discs and the joints of the spine. With factors such as age, injury, and poor posture, there is cumulative damage to the bone or joints of the spine. For example:
As the central spinal canal and the foramina thicken their ligaments, compression of the nervous system causes clinical symptoms.
Degenerative changes to normal vital tissue begin in early adulthood, but usually this slow process does not present with nervous system compression until we are in our sixth or seventh decades. Factors that can accelerate the degenerative process and bone spur growth in the spine include:
As always, to help avoid or minimize back pain it is generally advisable to stay well conditioned (both in terms of aerobics and strength) and to maintain good posture throughout one’s life.
