Objective To investigate the clinical value of CT in the diagnosis of lumbar spondylolysis and the improvement of its scanning technology. Methods CT findings of lumbar spondylolysis and CT findings of lumbar nerve compression were analyzed. Results CT scan showed isthmus fragmentation, and caused the spinal canal stenosis, lateral recess and foraminal stenosis and other concurrent changes.
