The oblique sagittal diameter of the lumbar spinal canal was measured by diagnostic ultrasound in seventy-three patients with symptomatic disc lesions, and compared with measurements from 200 asymptomatic subjects. Results suggest that the available space in the spinal canal is highly significant in the symptomatology of disc lesions, and in the patient's response to treatment.
通过诊断超声测量了73例有症状椎间盘病变患者的腰椎管斜矢状径,并与200例无症状受试者的测量结果进行了比较。结果表明,椎管内的可用空间在椎间盘病变的症状学以及患者对治疗的反应中具有高度显著性。
