Missed Back Pains Especially in Elderly – Kissing Spinous Processes – Baastrup’s Disease

Touching spinous processes in back can elicit pain, and may coexist with other problems so be easily missed. Cortisone injection is the first line treatment. I might have seen one lately that was puzzling that it was so localized – in an elderly patient that I was more concerned about rib impingement.

I wrote about this before but the concern over this is still voiced. Wrote here:

Localized Cause of Back Pain – Inter-Spinous Process Bursitis “Baastrup’s Disease”

  • a cause of localized back pain to spot between spinous processes where bursitis exists
  • Most commonly L4-5 – midline tenderness and often a single level
  • “some studies reporting an incidence as high as 81% in patients older than 80 years”
  • worse with extension – maybe much worse; and better with flexion
  • can see bone whitening (sclerosis) where spinous processes touch – inflamed.
  • “Extension of this inflammation through the ligamentum flavum may also contribute to central canal stenosis”
  • 6.3% of college athletes – especially gymnasts


  • poor posture
  • hyperlordosis
  • kyphoscoliosis
  • tuberculous spondylitis
  • stiff thoracolumbar transition
  • obesity
  • bilateral congenital hip dislocation

Symptoms – as above but also classic neurogenic claudication is comorbid with leg pain and weakness with standing or walking.

Plain and CT Imaging can often miss it, due to overexposure of films so MRI is most accurate and shows the soft tissue reaction.


  • physio to reduce lordosis
  • injection with local and steroid – they gave a case that it helped
  • spinal excision though not well established as helping

Comment – Given that commonly occurs with other issues, and can be missed on plain films; you will only see it if you know about it. Hopefully now you do. maillot de foot pas cher maillot de foot pas cher

One Response to Missed Back Pains Especially in Elderly – Kissing Spinous Processes – Baastrup’s Disease

    For me, it is excruciating. Especially in the morning. Also after sitting, reclining for any length of time. I have severe DDD L1-S1. Bones demineralized. A mess. I have always been physically active with perfect weight. This came on, it seems, quite suddenly,no trauma. Hurts.
