The most common X-ray of the lumbar spine is the frontal and lateral X-ray of the lumbar spine. The frontal X-ray of the lumbar spine mainly looks at whether there is scoliosis in the lumbar spine, whether there is hyperplasia in the lumbar spine, whether there is equal width of the vertebral space, whether there is bone destruction, whether there is hyperplasia, etc. The lateral X-ray of the lumbar spine also looks at whether there is narrowing of the vertebral space. There are also double oblique radiographs of the lumbar spine, which mainly look at whether there is isthmic discontinuity in the isthmus of the upper and lower synapses, and hyperflexion and hyperextension radiographs of the lumbar spine, which we also call power radiographs, which mainly look at whether there is instability of the lumbar spine. Through the orthogonal, lateral, double oblique and power films of the lumbar spine, we can determine whether the patient has diseases and other disorders of the lumbar spine.
