Arthrography was performed during steroid injection in 14 patients (22 joints) with noninflammatory conditions of the cervical facet joints. Two isolated spines were also studied. The capsular recesses were found to be quite large, especially near the intervertebral foramen. Though the appearance of the arthrogram was not clinically useful, it was helpful in positioning the needle for the steroid injection and confirming that the joint in question was abnormal. Distension of the capsule provoked pain in about 50% of cases; rupture of the distended capsule was rare but could account for leakage into the epidural space or foramen. Nine patients had significant relief of pain for three days to thirteen months.
对14例（22个关节）患有颈椎小关节非炎性疾病的患者在进行类固醇注射时进行了关节造影。还研究了两个孤立的椎体。发现关节囊隐窝相当大，尤其是在椎间孔附近。尽管关节造影的表现对临床没有帮助，但有助于确定类固醇注射的进针位置，并确认所讨论的关节是否异常。约50%的病例中，关节囊扩张会引发疼痛；扩张的关节囊破裂很少见，但可能导致硬膜外间隙或椎间孔渗漏。9例患者的疼痛在3天至13个月内得到显著缓解。
