THE ROLE OF THE SPINAL FACETS IN BACK AND SCIATIC PAIN

ALTHOUGH HEADACHE IS the most common symptom known to man, back and leg pain contribute the greatest disability. Each year at least 50,000 Americans are operated for "disc rupture". The failure rate of such surgery is exceedingly high with estimates of up to 40% failure to accomplish pain relief.1,2 The toll in workmen's compensation payments suggests the extent of the problem. In Wisconsin each year it is estimated that 75% of compensation payments go to back patients who represent only 3% of the total compensation patients!3
