INVESTIGATIONS ON THE REGULATION OF INTERVERTEBRAL DISC CELL MATRIX METALLOPROTEINASES

Funded Activity Summary

Degeneration of the intervertebral disc is a painful disabling condition with major socioeconomic consequences. Medical problems associated with disc degeneration and back-pain, of sufficient severity to warrant consultation with a physician, are experienced by 90% of the population some time during their lives. In man, back pain increases in incidence in the third and fourth decades of life, peaks in the fifties and declines thereafter. Changes in population demographics indicate this problem will increase in severity over the next few decades. American Bureau of Census data indicate that between 1990 to 2010 the number of people >45 years will increase from 82 to 124 million, the number of elderly in emerging countries will also increase between 200 to 400% in the next 30 years. In the United States, back-pain is the second most common reason that people visit a physician and medical conditions related to back-pain account for more hospitalisations than any other musculoskeletal disorder. Despite its high incidence, associated problems of incapacity and economic implications, costed at $100 million per annum in Australia in 1992, and US$100 billion globally in 1999-2000 (Dorland Data Networks, PA, USA) the causes of low back-pain are still poorly understood. Disc disease is responsible for 23-40% of all cases of low back-pain. The management of discogenic low back-pain is currently empirical, directed either toward life-style changes to minimise symptomatology or to surgical resection or spinal arthrodesis to restrict articulation. Based on our recent findings and those of colleagues over the last 16 years, it is our strong conviction that it should be possible with a better understanding of disease mechanisms and with the use of modern technologies to inhibit, reverse or ideally prevent disc degeneration. Without such basic research there will be no scientific foundation upon which prospective therapies may be based.
