Abstract:
Degenerative lumbar spinal stenosis, manifesting as chronic low back pain and neurogenic claudication, is an increasing chronic problem in an aging population, with limited effective conservative treatment options. Based on previous reports on the utility of subcutaneous calcitonin and two anectodal cases, we launched an open therapeutic trial of IV monthly pamidronate infusions, over a course of 3-6 months in this condition. Of 24 patients, 75% reported pain improvement, with the mean VAS score improved by 40%; while composite functional improvement in walking time, activities of daily living, and sense of well being was reported by 66%, with a mean improvement of 50%. The results of this pilot trial suggest the usefulness of this modality and warrant examination in a controlled clinical trial.
