Standard for lateral photography of lumbar spine

Compared with its upper and lower vertebral bodies, the lumbar vertebra 3 is flat, narrow at the front and wide at the back. Vertebral variation is easier to distinguish from fracture. In fact, the lumbar vertebra 3 is slightly wedge-shaped. The so-called wedge shape refers to the vertebral body whose lateral position is similar to a rectangle, and it becomes narrow in front (absolute) and wide in back (relative). This situation is more common in vertebral compression fractures and the development variation of vertebral bodies, depending on the degree of wedge and whether there is a history of lumbar trauma.

The left transverse mutation of lumbar vertebra 5 is wide, forming a pseudojoint with the sacrum-in fact, it is the sacrum of lumbar vertebra. Generally speaking, the lumbar vertebra 5 has a tendency to become a sacral vertebra. Intuitively, it seems that a lumbar vertebra is missing and a sacral vertebra is added. This is type IIA, that is, one lateral transverse process and sacrum form a pseudojoint. Some people may feel lumbosacral pain and discomfort, while others have no symptoms.
