1. Attention is called to the isolated fractures of the articular processes of the lumbar vertebrae.
2. This fracture is frequently unrecognized because of imperfect roentgenographic detail, and the patient is frequently treated for low back strain.

4. For those cases that do not respond to conservative treatment, operation is advised, including spinal fusion, arthrodesis of the involved joint, and removal of the fractured fragments.
