Spinal stenosis can be characterized by low back pain in the early stages, and as the disease continues to progress, it can eventually develop into lower extremity weakness, difficulty walking, and in severe cases, incontinence. Spinal stenosis is often characterized by low back pain in the early stages, followed by pain in one or both lower limbs, which may be aggravated by standing or walking, and may be accompanied by sensory abnormalities (numbness, etc.). Intermittent claudication (a feeling of weakness in the calf after walking for a certain distance, relieved by rest, and repeated after walking again) can occur with further development of the disease. Severe spinal stenosis can cause compression of the cauda equina nerve, leading to sphincter dysfunction and urinary incontinence. When the symptoms of spinal stenosis are mild, the symptoms can be relieved by conservative treatment (bed rest, physical therapy, etc.), but when the symptoms are more severe, decompression of the spinal canal or decompression of bone graft fusion and internal fixation should be performed as soon as possible to relieve the symptoms of nerve compression as soon as possible, so as to avoid aggravation of the disease and affecting the prognosis.
