Intradiscal glycerol of bupivacaine in the treatment of low back pain
Summary A total of 15 patients suffering from chronic low back pain were treated with an intradiscal injection of either 1 ml of 50 % glycerol or 2 ml of 0.5 % bupivacaine . Most ( 60 % ) of the patients had previously undergone spinal surgery for lumbar disc herniation or spinal stenosis and 73 % showed clinical signs and symptoms of segmental instability of the lumbar spine . According to self-evaluation question naires , immediate response to both treatments was mainly good . Of the 9 patients who received glycerol , 56 % showed subjective improvement on the first day after the injection and after two weeks , 45 % of the patients still felt improvement . After one month , however , the pain had reappeared in all except one ( 11 % ) patient . The corresponding numbers for the 6 with bupivacaine treated patients were 83 % , 67 % , and 17 % . Based on the very short duration of response to the treatment , we did not find intradiscal injections with these agents to be cost-effective . In our department , this therapeutic approach is no longer employed in patients with chronic discogenic pain
