    Sammanfattning : One of the major health problems in western societies is back pain, with a prevalence rate of 49%–80%. In many cases, the back pain is due to degenerated discs. The gold standard to treat a severely degenerated disc is spinal fusion, where the vertebral disc is replaced with a cage structure. LÄS MER

    Sammanfattning : Ankylosing Spondylitis (AS), or Bechterew’s disease, is an inflammatory rheumaticdisease that through the formation of additional bone tissue in the spine eventuallyleads to the complete fusion of the vertebrae, in effect turning the spine into one longbone. Due to the reduced flexibility of the spine with the long lever arms, spinalfractures in AS-patients are relatively common even after minor trauma. LÄS MER
