Lumbar Stenosis Outcomes Research II

Summary

The primary objective of the proposed pilot study is to determine the efficacy of oxymorphone hydrochloride and propoxyphene/acetaminophen combination in prolonging the time to onset of pain and reducing the severity of pain associated with walking in patients lumbar spinal stenosis that have clinical symptoms of neurogenic claudication. Neurogenic claudication is defined as movement induced leg pain, numbness, heaviness, or vague discomfort in part or all of one or both legs provoked with walking and standing and relieved by sitting, squatting, or forward flexion posturing. The secondary objective is to examine the functional benefit of oxymorphone hydrochloride and propoxyphene/acetaminophen combination with respect to improvement in duration and distance of walking.
