Abstract：
BACKGROUND: Congenital lumbar facet joint defect is a rare congenital developmental disorder with only a few reported cases in the literature, primarily affecting the L5-S1 segments. This study reports the first case of a defect in the left L3 inferior articular process; and presents a review of the existing literature on the subject, proposes a classification system, and validates the inter-observer and intra-observer reliability of this classification system.
METHODS: A 14-year-old boy presented to our orthopedic clinic with persistent lower back pain for 1 month. Imaging analysis, including CT scans, 3D reconstruction, and MRI, revealed a congenital lumbar facet joint defect at the L3 level, which has not been reported. Conservative treatment resulted in a significant improvement in his symptoms, and he is currently under follow-up care.
CONCLUSIONS: Congenital defect of the lumbar facet joint is a rare spinal condition. This article reports the first patient with a defect in the left L3 inferior articular process and conducts a comprehensive literature review, proposing a classification of articular process defects into five types. The two most common types are Types B and C. We have demonstrated that this system is reliable and reproducible and have described the treatment of each type.

摘要：
背景：先天性腰椎小关节缺损是一种罕见的先天性发育障碍，文献中仅报道了少数病例，主要影响L5-S1段。本研究报告了第一例左L3下关节突缺损；并对该主题的现有文献进行了综述，提出了一个分类系统，并验证了该分类系统的观察者间和观察者内可靠性。
方法：一个14岁的男孩出现在我们的骨科诊所，持续1个月的下背部疼痛。成像分析,包括CT扫描,三维重建,MRI,在L3水平显示先天性腰椎小关节缺损，尚未报告。保守治疗使他的症状明显改善,他目前正在接受后续治疗。
结论：先天性腰椎小关节缺损是一种罕见的脊柱疾病。本文报道了首例左L3下关节突缺损的患者,并进行了全面的文献复习,提出将关节突缺损分为五种类型。两种最常见的类型是B型和C型。我们已经证明了该系统是可靠的和可重复的,并且已经描述了每种类型的处理。
