1, intermittent claudication
Intermittent claudication can be caused by nerve compression in lumbar spinal canal or vascular disease of lower limbs, which can be divided into nerve intermittent claudication and vascular intermittent claudication clinically.
① Intermittent claudication
With the increase of age, the intervertebral disc in front of the spinal canal swells and even protrudes after dehydration, and it squeezes into the spinal canal from the front, while the ligamentum flavum and facet joint capsule in the rear proliferate and hypertrophy, and the facet joints also proliferate and hypertrophy like fists, which oppresses the spinal canal from the rear and sides.
Spinal canal stenosis comes from spinal deformity, and it is common that the vertebral body is unstable or even obviously slipped, which makes the continuous and smooth spinal canal twist or turn.
Spine. Primary or metastatic tumors grow into the spinal canal, or the spinal cord or cauda equina itself grows tumors in the spinal canal, or the metastatic tumors in the spinal canal occupy the spinal canal.
② Intermittent claudication of blood vessels
The pain of patients with intermittent vascular claudication is more related to exercise than to the change of spinal posture. Its symptoms are prone to one side, accompanied by cold sensation, and generally there is no sensory paralysis. When you stop walking, the symptoms can be improved or disappeared. Most importantly, the pulse of the dorsal foot artery on this side must be weakened or disappeared because of arterial occlusion.
2. Osteoarthritis
Osteoarthritis is a pathological joint disease characterized by degeneration, degeneration and hyperplasia of articular cartilage. Most of them have hidden onset and slow progress, and the most prominent symptom is joint pain.
Osteoarthritis is characterized by: pain-relief-pain again, recurrent attacks. When I get up in the morning, the pain is more severe. A little exercise will relieve the pain. After excessive activity, the pain will reappear and can be relieved again after rest. If you stay in a certain position for a long time, or exercise for a long time, the pain will start again, and you can hear the rough rubbing sound of the joints. With the increase of age, the symptoms will gradually worsen, which can also affect other joint parts.
3. osteoporosis
Primary type I osteoporosis is due to the decrease of estrogen after menopause, which increases bone absorption and leads to bone loss. Therefore, bone resorption inhibitors such as estrogen, calcitonin and calcium preparations should be selected for treatment.
Primary type ⅱ osteoporosis is caused by aging, which leads to imbalance of hormone self-regulation and low bone formation. Bone formation promoters, such as active vitamin D, anabolic steroids, fluorinating agents and vitamin K2, should be selected for treatment.
4, arteriosclerosis of lower limbs
Old cold legs are arteriosclerosis obliterans of lower limbs that occur every year with the decrease of temperature.
Atherosclerotic occlusive disease of lower limbs refers to the formation of atherosclerotic plaques on the inner wall of arteries, which proliferate and protrude into blood vessels. With the continuous expansion of plaque and the formation of secondary thrombosis, blood vessels become narrower, blood flow slows down and blood flow decreases. When the stenosis reaches a certain degree, even the lumen is blocked, and the blood flowing to the lower limbs can not meet the needs of the human body, chronic or acute ischemic symptoms will appear in the lower limbs.
