The correlation between facet joint asymmetry and disorders of the lumbar spine was analyzed in a study of plain radiographs, computed tomograms and magnetic resonance images from 76 normal subjects and 173 patients who underwent lumbar surgery. Of 76 normal controls who were studied by means of plain radiographs, only 21 (27.6%) had facet asymmetry at the level of L4-5 or L5-S1, while 84 (48.6%) of 173 patients who were studied with plain radiographs, and partially with CT or MRI, were noted to have facet asymmetry. The difference was highly significant (P < 0.01). This study supports the etiologic significance of facet asymmetry in lumbar disorders.
在一项对76名正常受试者和173名接受腰椎手术患者的X线平片、计算机断层扫描和磁共振成像的研究中，分析了小关节不对称与腰椎疾病之间的相关性。在通过X线平片进行研究的76名正常对照者中，只有21名（27.6%）在L4-5或L5-S1水平存在小关节不对称，而在通过X线平片并部分结合CT或MRI进行研究的173名患者中，有84名（48.6%）被发现存在小关节不对称。差异具有高度显著性（P < 0.01）。本研究支持小关节不对称在腰椎疾病病因学中的重要意义。
