BackgroundCongenital 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.Case PresentationA 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.ConclusionCongenital 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.

“…Several congenital spinal anomalies and their association with systematic anomalies have been reported. 1,2) There are also reports on several types of anomalies at lumbosacral facet joints, such as congenital absence of lumbosacral facet joint [3][4][5][6] and two separate facet joints on the same lumbosacral facet joint, 7) but there are no reports on unilateral lumbosacral facet abnormality resembling "facet interlocking" (Fig. 4).…”

We report a rare case presenting radiculopathy caused by unilateral lumbosacral facet abnormality resembling facet interlocking. The patient was a 57-year-old man with no medical and traumatic history. He began to exhibit numbness below his left ankle followed by pain at the left buttock with no obvious causes. He visited our hospital approximately 1 year after the onset of his symptom. Preoperative images revealed a left lumbosacral facet abnormality resembling facet interlocking. His left S1 nerve root was compressed by the dislocated left L5 inferior articular process and bone fragment. His symptom was consistent with left S1 radiculopathy without an obvious stenosis of the left L5 intervertebral foramen; thus, we performed partial facetectomy of the left L5/S1, posterior decompression of the S1 nerve root tunnel, and removal of bone fragment. After the operation, his symptom completely disappeared with satisfactory result. There are several types of congenital facet anomalies in the lumbosacral facet joint; however, congenital unilateral lumbosacral facet abnormality resembling facet interlocking described in this paper has not been reported. His clinical symptom was completely recovered after simple decompression surgery. In this paper, we report the interesting and unique findings of facet abnormality resembling facet interlocking.
