Lumbar degenerative kyphosis. Clinical, radiological and epidemiological studies.

摘要: We suggest that lumbar degenerative kyphosis be included as one of the abnormal sagittal curvatures in which a or marked loss lordosis is seen spine, caused by changes middle-aged and elderly. One hundred five consecutive patients were investigated, most whom complained low-back pain, often with long history. They all walked forward bending posture, either time only when exhausted. In roentgenograms, cases showed sacral inclination, well multiple disc narrowing and/or vertebral wedging region. These subjects definite weakness extensors compared to flexors, therefore reversed ratio extensors/flexors muscle power normal controls other types spinal curvatures. Weakness was clearly shown isokinetic measurement atrophy these muscles fatty infiltration demonstrated CT scanning.
