Abstract

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.
