In the past six months, 68-year-old Granny Li has felt her “foot strength” has significantly decreased, walking for half an hour on the road leg discomfort, must sit down to rest for a while, before walking again. After going to the hospital for a checkup, she was told that she had lumbar spinal stenosis. For this diagnosis, Granny Li felt some fear, lumbar spinal stenosis is mostly seen in the middle-aged and elderly, is a common cause of back and leg pain and weakness of the lower limbs of many people walking. As people enter middle and old age, various tissues age, degenerate and proliferate, and the lumbar spinal canal is no exception. The soft tissues in this vicinity become enlarged and thickened, lumbar discs bulge or even protrude, and bony growths occur, while causing the space around the nerves to become smaller and compressed. If you carefully keep images of the spinal canal when you are young and compare them with images of the spinal canal in old age, the spinal canal in old age will definitely be narrower than in young age. In other words, every elderly person may have varying degrees of spinal stenosis. This is a “geriatric disease”, so to speak, and is not something to be overly concerned about. The vast majority of seniors have varying degrees of spinal stenosis, and there are many conservative treatments that can alleviate the discomfort, with surgery being considered only when life is severely compromised.
