我们建议将腰椎退行性后凸纳入其中一种异常矢状曲度，即腰椎后凸或前凸明显丧失，由中老年人退行性改变引起。连续对一百零五名患者进行了调查，其中大多数人抱怨腰痛，而且往往有很长的病史。他们都以向前弯曲的姿势行走，要么一直，要么只有在筋疲力尽的时候。在X射线照片中，大多数病例显示骶骨倾斜度明显丧失，以及腰椎区域多处椎间盘狭窄和/或椎骨楔入。与屈肌相比，这些受试者表现出腰部伸肌的明显无力，因此与正常对照和其他类型的脊柱弯曲相比，伸肌/屈肌的肌力比率相反。等速测量清楚地显示腰伸肌无力，CT 扫描显示这些肌肉明显萎缩并伴有脂肪浸润。
We suggest that lumbar degenerative kyphosis be included as one of the abnormal sagittal curvatures in which a kyphosis or a marked loss of lordosis is seen in the lumbar spine, caused by degenerative changes in middle-aged and elderly. One hundred and five consecutive patients were investigated, most of whom complained of low-back pain, often with a long history. They all walked in a forward bending posture, either all the time or only when exhausted. In roentgenograms, most cases showed a marked loss of the sacral inclination, as well as multiple disc narrowing and/or vertebral wedging in the lumbar region. These subjects showed a definite weakness of the lumbar extensors compared to the flexors, and therefore a reversed ratio of extensors/flexors muscle power compared with normal controls and other types of spinal curvatures. Weakness of the lumbar extensors was clearly shown by isokinetic measurement and a marked atrophy of these muscles with fatty infiltration was demonstrated by CT scanning.
