Intervertebral space changes

Introduction Intervertebral space changes manifest as abnormal widening, stenosis or disappearance of the intervertebral space. The lateral space of the intervertebral space can show the space where the intervertebral disc is located. In the lumbar vertebrae, the intervertebral space gradually increases from top to bottom and is narrower and narrower than L5S1 to accommodate the lumbosacral angle. When the disc is degenerated, the gap of L4-5 or L5S1 can be narrow, but the gap is narrowed and the disc is not protruding. Equivalent. Local protrusion of the intervertebral disc of young adults does not necessarily show stenosis of the intervertebral space.

Cause

Mainly found in spinal trauma, disc herniation, spinal tuberculosis, tumors and congenital dysplasia.

Spinal MRI examination of the spine examination of bone and joint soft tissue CT examination

From the X-ray, it is seen that the change of intervertebral space is an X-ray manifestation of intervertebral protrusion. It is best to be diagnosed by CT.

Differential diagnosis

Differential diagnosis of intervertebral space changes:

1, the size of the spinal canal changes: the size of the spinal canal changes mainly manifested as stenosis and enlargement of the spinal canal.

2. Spinal cord compression: Spinal cord compression refers to a group of diseases in which the spinal cord, spinal nerve roots, and their supply vessels are compressed by lesions of various natures.

3, spina bifida: spina bifida is due to congenital spinal canal regurgitation, the formation of a rupture in the dorsal or ventral side of the spine, with or without the deformity of the meninges and nerve components. Clinically, such malformations are very common, accounting for 5% to 29% of the census population. Among them, the first and second atlas and the fifth lumbar vertebrae. The main reason for this is the developmental disorder of the cartilage center or the osteogenesis center in the embryonic stage, so that the bilateral vertebral arches do not fuse at the back to form a wide and narrow fissure. Simple bony fractures are called recessive spina bifida, the most common; if accompanied by meningocele or spinal cord bulging, it is dominant spina bifida, accounting for 1 2 , the latter is quite difficult to treat, and Mostly in the category of neurosurgery.
