Classification according to ICD-10
M43.2 Other vertebral fusion
Q76.4 Other congenital malformations of the spine without scoliosis
ICD-10 online (WHO version 2019)

The partial or complete fusion of two or more vertebral bodies is referred to as a block vortex . The amalgamation can be caused by a developmental disorder ( dysontogenic block vertebra) or acquired in the course of life.

A dysontogenetic block vertebra formation can be found, for example, in the Klippel-Feil syndrome .

Acquired block vortices can z. B. after inflammation of the vertebrae and intervertebral discs (e.g. after tuberculosis ), after trauma or with pronounced degeneration of the intervertebral discs and adjacent vertebrae ( osteochondrosis intervertebralis ).

Other vertebral abnormalities

  • Block vertebrae on the cervical spine (HWK 4 and 5). From the picture, probably on the basis of degenerative or inflammatory changes.

  • Several congenital block vertebrae in the transition from the thoracic to the lumbar spine and hemi-vertebrae with hemimetameric segment shift in the upper thoracic spine.

  • Congenital block vertebrae in the lumbar spine (partially LWK 3 and 4). The back part of the intervertebral disc is still preserved.
