palpation of the lumbar spine

Last reviewed 01/2018

Localised tenderness in the lumbar spine may be caused by damage to:

  • muscle - either trauma to the muscles or as a result of protective spasm
  • ligament - sprains or rupture
  • bone - fractures of e.g. transverse process, spinous process or body of vertebra
  • intervertebral disc - a prolapsed disc may cause localised pain as well as referred pain

Special attention is paid to tenderness at the lumbosacral junction. A sprain of the sacroiliac joint results in tenderness alone; in cases of lumbosacral junctional spondylolisthesis tenderness may be accompanied by a palpable step.
