Clinical manifestation and types Primary osteoporosis ： TypeⅠpostmenopausal osteoroposis——This is seen with estrogen deficiency. There is high bone turnover rate. The proportion of trochanteric and femoral neck fractures increases； TypeⅡelderly osteoroposis——This is aging in bone physiology. The compression fracture of the spine and hip fracture are more common
Clinical Features of osteoroposis The vast majority of hip fractures occur after a fall. About 5% appear to be spontaneous"fractures, in Which the patient feels a fracture and then falls Overall about half of hip fractures are intertrochanteric and the others are femoral neck fractures

Clinical Features of osteoroposis Vertebral compression fractures vary in degree from mild wedges to complete compression. The symptoms also vary, but the degree of compression is not necessarily related to the amount of pain. In fact, about 60% of women with compression fractures do not realize they have had a fracture! It is possible that some of the fractures occurred gradually and therefore did not cause acute pain

CLinical Features of Osteoroposis When women and men do suffer painful compression fractures, the pain usually lasts from one to two months is localized to the back with accompanying muscle spasms, then gradually subsides Patients with continuing severe pain should be evaluated for other pathologic etiologies of the fracture, especially malignancy or myeloma Persistent pain can also be caused by continuing fracture, muscle spasms, spinal stenosis, or degenerative joint disease

Clinical Features of osteoroposis w To correctly interpret a spine xray, it is important to know the definition of a vertebral fracture, which is not quite as straightforward as it first appears especially for research For practical clinical purposes, a vertebra can be considered fractured if the anterior height is 80% or less of the posterior height a new fracture requires loss of at least 20% of anterior or posterior height
