Kümmell disease

Assoc Prof Frank Gaillard and Radswiki et al.

Kümmell disease is an eponymous name for osteonecrosis and collapse of a vertebral body.

Kümmell disease represents delayed (usually two weeks) vertebral body collapse due to ischemia and non-union of anterior vertebral body wedge fractures after major trauma.

Risk factors include:

  • osteoporosis
  • corticosteroid use
  • alcoholism
  • radiation therapy
  • shows collapse of affected vertebrae (typically lower thoracic and upper lumbar)
  • an intravertebral vacuum cleft and fluid may be seen (accentuated on extension stress lateral views), although this is non-specific
  • the intravertebral vacuum cleft is usually seen as low signal intensity with all sequences
  • if intravertebral fluid is present it is low T1 signal and high T2 signal

The severity of the vertebral collapse has been found to be higher in those who have intravertebral gas compared to those who only have intravertebral fluid, signifying that the presence of intravertebral gas is possibly a more advanced stage of the disease 1

This condition was first described by Hermann Kümmell (1852-1937), a German surgeon, in 1891 4,8.
