There are many signs of orthopedic disease before the onset of the disease, such as pain, dizziness, walking with a thumping sound, and frequent leg and foot cramps are all warning signs of bone disease. At this point, you may ask, can leg cramps also be related to orthopedic diseases? The following will tell you the causes of leg cramps and leg cramps and orthopedic diseases have what connection! 1, lack of calcium: this is usually known to everyone. In the process of muscle contraction, calcium ions play an important role. When the concentration of calcium ions in the blood is too low, the muscles are easily excited and cramped. Older women estrogen decline, osteoporosis, will make the blood calcium level is too low, muscle stress increases often occur leg cramps, adolescent growth and development is rapid, it is easy to lack of calcium, so it often happens leg cramps. 2, continuous muscle contraction too fast: strenuous exercise, the whole body is in a state of tension, the leg muscles contract too fast, the relaxation time is too short, the local metabolites lactic acid increased, the muscle contraction and relaxation is difficult to coordinate, thus causing calf muscle cramps. 3, cold stimulation: such as winter exercise in a cold environment, inadequate preparation activities are likely to cause leg cramps. Sleeping at night without covers, calf muscles stimulated by the cold, will spasm so much that people wake up in pain. 4, excessive fatigue: when long-distance travel, climbing, climbing, calf muscle fatigue is most likely to occur. When it is fatigued to a certain extent, spasms will occur. Excessive sweating. Exercise for a long time, a lot of exercise, sweating, and no timely replenishment of salt, a large loss of body fluid and electrolytes, metabolic waste accumulation, poor local blood circulation of the muscle, also prone to spasm. 5, poor sleep posture: such as a long time lying on your back, so that the quilt pressed on the surface of the foot, or a long time lying prone, so that the surface of the foot against the bed, forcing some muscles in the calf for a long time in absolute relaxation, will also cause muscle “passive spasm”. 6, systemic diseases: systemic diseases make the leg vascular sclerosis plaque formation, poor blood circulation, such as cardiovascular disease, hypertension, high blood pressure, high blood pressure, diabetes family history, when the lower limb pain, leg cramps, walking inconvenience and other symptoms, should think about whether there is atherosclerosis, such as lower limb arterial occlusive disease. 7, cramps behind the hidden more easily ignored orthopedic diseases: for example, the incidence of leg cramps can be as high as 70% in patients with lumbar disc herniation. Degenerative spinal lesions occur with age and degenerative changes, such as osteophytic ligamentous hypertrophy, which compress the blood vessels within the spinal nerve roots, causing a decrease in blood flow also often occur leg cramps. Spinal stenosis with sciatic nerve compression will present with leg cramp symptoms early on, and furthermore intermittent claudication will occur. Because the symptoms of leg cramps are often overlooked, some patients with this orthopedic condition are treated as general leg cramps or calcium deficiency and their condition is delayed. Therefore, once again, we remind you that you must pay attention to leg cramps and not treat them as a general calcium deficiency!
