Osteoporosis (osteoporosis) is a group of bone diseases caused by multiple causes, where there is normal calcification of bone tissue, a normal ratio of calcium salts to matrix, and a metabolic bone lesion characterized by a decrease in the amount of bone tissue per unit volume. In most cases of osteoporosis, the decrease in bone tissue is mainly due to increased bone resorption. The onset of osteoporosis is slow and individual is fast, characterized by skeletal pain and easy fracture, and the biochemical examination is basically normal. The pathological anatomy reveals a thin bone cortex and sparse atrophy of the bone trabeculae with no thick bone layer. Clinical manifestations of pain: the most common symptom of primary osteoporosis, low back pain is common, accounting for 70%-80% of patients with pain. The pain spreads along the spine to both sides, decreases when lying on the back or sitting, and increases when posterior extension or prolonged standing or sitting, and is lighter during the day and worse at night and early morning when waking up, and increases when bending, muscle movement, coughing, and bowel movement. Shortening of body length and hunchback: mostly occurs 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, which is heavy and easily compressed and deformed, causing the spine to tilt forward and the back to curve more, resulting in hunchback. Fracture: This is the most common and serious complication of degenerative osteoporosis. Decreased respiratory function: compression fractures of the thoracic and lumbar vertebrae, backward curvature of the spine, and thoracic deformity can significantly reduce lung capacity and maximum air exchange, and patients can often experience chest tightness, shortness of breath, and difficulty in breathing. For the elderly, osteoporosis prevention and treatment is very important. Bone densitometry is the most direct means of diagnosis.
