We carried out an MRI study of the lumbar spine in 15 patients with achondroplasia to evaluate the degree of stenosis of the canal. They were divided into asymptomatic and symptomatic groups. We measured the sagittal canal diameter, the sagittal cord diameter, the interpedicular distance at the mid-pedicle level and the cross-sectional area of the canal and spinal cord at mid-body and mid-disc levels. The MRI findings showed that in achondroplasia there was a significant difference between the groups in the cross-sectional area of the body canal at the upper lumbar levels. Patients with a narrower canal are more likely to develop symptoms of spinal stenosis than others.
我们对15例软骨发育不全患者的腰椎进行了磁共振成像（MRI）研究，以评估椎管狭窄程度。他们被分为无症状组和有症状组。我们测量了矢状径椎管直径、矢状径脊髓直径、椎弓根中部水平的椎弓根间距以及椎体中部和椎间盘中部水平的椎管和脊髓横截面积。MRI结果显示，在软骨发育不全患者中，上腰椎水平的椎体管横截面积在两组之间存在显著差异。椎管较窄的患者比其他患者更易出现椎管狭窄症状。
