(1) pain: primary osteoporosis, the most common disease syndrome to low back pain more common, accounting for 70% of patients with pain -80%. Pain along the spine to both sides of the proliferation, to reduce pain when supine or sitting, upright hours after a long stretch, or lap, sedentary, when the pain intensified, the pain during the day light, night and early morning wake up heavier bending, muscle movement, coughing, worse when stool force. Usually more than 12% of bone mass loss can occur when the bone pain. Senile osteoporosis, the vertebral trabecular bone atrophy, reducing the number of vertebral compression deformation, spinal flexion, lumbar flexion in order to correct the spine, double contraction, muscle fatigue or spasm, producing pain. The newly thoracolumbar vertebral compression fractures, can also produce acute pain, the corresponding parts of the spine may have a strong spinous process tenderness and percussion pain, usually after 2-3 weeks gradually reduced, in some patients with chronic low back pain can be presented. If the oppression of the corresponding spinal nerve can produce limb Fangshe Tong, double lower limb sensory-motor disorder, intercostal neuralgia, chest pain similar to angina, but also may appear similar to the acute abdomen on the abdominal pain. If the oppression of the spinal cord, cauda equina is also affecting the bladder, rectum function.
(2) The length shortened, hump: multi-in pain later. Anterior spinal vertebra is almost mostly composed of trabecular bone, but also the backbone of this part of the body, the negative weight of large, particularly in the first thoracic and 3 lumbar vertebrae 11,12, a larger load, easy to compressive deformation, so that the spine forward, Qu increased back to form a hump-back, with age, osteoporosis heavier humpback curvature increased, resulting in a significant knee twin arrest. Each person will have 24 vertebrae, each vertebra normal altitude of about 2cm or so, the elderly osteoporotic vertebral compression, each about 2mm shorter vertebral body, length reduced by an average 3-6cm.
(3) fracture: This is a degenerative osteoporosis, the most common and most serious complications, which not only increase the suffering of the patients, reinforce the economic responsibility and severely restricts a patient's activities, and even shortened life expectancy. According to our statistics, the elderly fracture incidence of 6.3-24.4%, especially for senior citizens (80 years or older) female elderly staggering. Fractures caused by osteoporosis in old age early in distal radius fractures (Colles fracture) more common, old age after a period of lumbar spine and proximal femur fractures more common. Usually more than 20% bone loss occurs when the fracture. BMD is reduced by 1.0DS, the incidence of vertebral fractures increased 1.5-2 times. Vertebral compression fractures that about 20% -50% of patients had no obvious symptoms.
(4) The respiratory function decline: thoracic and lumbar vertebral compression fractures, spine, after bending, thoracic deformities, lung capacity and maximum ventilation can significantly reduce lung upper lobe anterior lobular emphysema incidence of up to 40%. Most elderly people have no degree of emphysema, lung function decline with aging, if combined with osteoporosis caused by thoracic deformity, the patient can often arise chest tightness, shortness of breath, difficulty breathing and other symptoms.
