The relationship between the cross-sectional area of the cauda equina and the preoperative symptoms in central lumbar spinal stenosis

A cross-sectional registry and imaging cohort study. To study the association between typical symptoms and signs of central spinal stenosis and the minimum cross-sectional area (mCSA) of the cauda equina in patients subsequently undergoing surgery. Relations between mCSA and the symptoms of spinal s...

Description
Summary:A cross-sectional registry and imaging cohort study. To study the association between typical symptoms and signs of central spinal stenosis and the minimum cross-sectional area (mCSA) of the cauda equina in patients subsequently undergoing surgery. Relations between mCSA and the symptoms of spinal stenosis have not been studied before. The preoperative walking ability, pain in the leg(s) and back, duration of symptoms and quality of life in 82 men and women subsequently operated for spinal stenosis were related to the digitally determined CSA of the single most constricted level, mCSA of their lumbar spines. A smaller mCSA was directly related to a shorter walking distance before claudication. A small mCSA meant more leg and back pain and a lower health-related quality of life.
