“…The exact etiology is still unknown but the accepted explanation is as follows: there are three primary ossification centers in each vertebra: two centers in the neural arches and one center in the vertebral body. The facet defect is thought to be caused by failure of these ossification processes during fetal life [4–6]. It is postulated that this failure is due to insufficient blood supply during fetal life [4].…”

“…The etiology is presumed to be due to a dysfunction of the vertebral ossification centers during fetal life, which consist of two centers in the neural arches and one center in the vertebral body [4, 5]. Surgical intervention consisting of spinal fusion is rarely performed [4], and most cases are resolved with conservative treatment, especially in patients with no instability. We report a case of unilateral absence of the fifth lumbar inferior articular process with a review of the relevant literature.…”

A congenital absence of the lumbar facet joint is a rare reported condition. This is the case of a 32-year-old male patient presenting with severe low back pain radiating to his right lower limb. Physical examination revealed no motor deficits, but right lower limb numbness was reported over dorsum aspect of the right foot. No other sensory or motor disturbances were reported or found on exam. Imaging studies, consisting of a spine MRI and spine CT scan with 3D reconstruction, revealed the absence of the right L5-S1 zygapophyseal joint. The patient was treated conservatively with resolution of his symptoms on one-month follow-up.

A congenital absence of a lumbar articular process is a rare condition with an uncertain etiology. However, an intervertebral instability caused by this anomaly can cause occasional lower back pain. A 20 years old man presented with lower back pain. The physical examination revealed no neurological deficits. Plain radiographs of the lumbar spine revealed an absence of the left inferior articular process at the fourth lumbar vertebra associated with hypoplasia of the left lamina. The patient's symptoms were resolved after conservative treatment. We report a case of a congenital absence of articular process at the fourth lumbar vertebra.

“…11) Only 26 cases have been reported since then, indicating this condition is extremely rare. 2,[5][6][7][9][10][11][12][13][14][15][16][17][18][19] The etiology of this disease may be abnormal ossification in the center of the vertebral arch starting from about 9 weeks of embryonic development, 3,8) which is reportedly often observed in the lumbar vertebrae and rarely in the cervical or thoracic vertebrae. 4,18) We treated a patient with congenital absence of the lumbar facet joint associated with spondylolysis of the fifth lumbar vertebra.…”

A 14-year-old boy presented with a rare case of congenital absence of lumbar facet joint manifesting as low back pain. Physical examination showed no neurological or hematologic abnormalities. Radiography revealed absence of a facet joint on the right side of L4-5. Computed tomography and threedimensional computed tomography revealed absence of the facet joint on the right side of L4-5 and spondylolysis on both sides of L5. Pain subsided after conservative treatment. This is an extremely rare case of congenital absence of lumbar facet joint associated with bilateral spondylolysis.
