A case of an anomalous ossicle in a lumbar facet joint is reported and the operative findings presented. The nature of the anomaly is not fully understood but is thought to be the result of non-fusion between a normal appearing ossification center and the adjacent articular process. The patient's symptoms--severe chronic low back pain--subsided completely after surgery. It is concluded that the presence of such ossicles in facet joints in some cases may lead to severe symptoms and that surgical treatment in such cases should be considered.
本文报告了一例腰椎小关节内异常小骨的病例，并展示了手术所见。该异常的性质尚未完全明确，但推测是由于一个外观正常的骨化中心与相邻关节突之间未融合所致。患者的症状——严重的慢性下腰痛——在手术后完全缓解。结论是，在某些情况下，小关节内存在此类小骨可能会导致严重症状，对此类病例应考虑手术治疗。
