Osteoporosis is a group of bone diseases caused by a variety of causes. The bone tissue has a normal calcification and a normal ratio of calcium salts to matrix, with a decrease in the amount of bone tissue per unit volume as a characteristic. In most osteoporosis, the reduction of bone tissue is mainly due to increased bone resorption. In most osteoporosis, the decrease in bone tissue is mainly due to increased bone resorption. The onset of the disease is slow and individual is fast, characterized by skeletal pain and easy fracture. The pathological anatomy shows thin bone cortex and sparse atrophy of bone trabeculae with no thick bone layer. Clinical common patient general discomfort, back and leg weakness, inexplicable bone pain. After detailed examination and diagnosis of osteoporosis, some painkillers and calcium supplements can be taken appropriately. The common clinical manifestations of osteoporosis are: 1. Pain: The most common symptom of primary osteoporosis is low back pain, which accounts for 70%-80% of the patients with pain. Pain spreads along the spine to both sides, decreases when supine or sitting, increases when posterior extension or prolonged standing or sitting, is light during the day, increases at night and when waking up in the morning, and increases when bending, muscle movement, coughing and bowel movement. 2.Shortening of body length and hunchback: mostly appear after pain. The anterior part of the vertebrae of the spine is almost mostly composed of cancellous bone, and this part is the pillar of the body, with a large weight, easily compressed and deformed, so that the spine tilts forward and the dorsal curvature increases, forming a hunchback, with age, osteoporosis increases, the hunchback curvature increases, resulting in significant knee contracture. 3, fracture: This is the most common and serious complication of degenerative osteoporosis. 4, respiratory function decline: compression fractures of thoracic and lumbar vertebrae, backward curvature of the spine, thoracic deformity, can significantly reduce lung capacity and maximum air exchange, patients can often appear chest tightness, shortness of breath, dyspnea and other symptoms.
