I meet clinicians who seem unconvinced of value of B-mode high-resolution ultrasound compared to radiographic exam to investigate foot degenerative joint disease. I am posting an illustrative example for discussion. As usual I am keen to meet a contrary viewpoint; I believe that US may have greater value than CR as first line to investigate non traumatic midfoot pain.

Presentation:

• Referral from physiotherapist for non responsive foot pain. 60 yo female; denied prior foot surgery, persistent fairly severe bilateral dorsal midfoot pain worsening and of several years duration. Insidious onset and denied recollection of a traumatic event.
• Primary care physician ordered recent radiographic exam radiology was reported normal.
• Subsequent scintigraphy suggestive for degenerative joint disease but poorly specific for site.
• Some pain on rising from bed in morning; worsens towards end of day.
• Occupation as airport security officer requires constant standing and walking at work.
• Reported being unable to exercise because of her foot pain.
• Reported being in good general health.
• Primary care physician prescribed Celebrex; this has been used for past four weeks without significant benefits so far.

I observed:

• Bilaterally some mild swelling and tenderness at dorsal midfoot, left greater than right. Provocative testing with double limb stance heel raise resulted in generalised dorsal midfoot pain

non weight-bearing CRs of this case attached as .pdfs

Point of this thread is to see if anyone can accurately detect site of degenerative joint disease from attached CR (I can't).

I will post US images as alternative to CR and scintigraphy for those interested after several days to illustrate value of US in this type of case.

Mart;

I only looked at the first and last image but I agree with you, I see no signs of DJD on those x-ray films.

I'm interested to see the other images you post.

Martin:

I don't normally iniitally perform either x-rays, ultrasound, CTs or MRIs on these patients. I treat them as dorsal midfoot interosseous compression syndrome and 80% of them get better. If they don't improve, then I start with x-rays.

Dorsal Midfoot Interosseous Compression Syndrome

Do you, Martin, perform US, CTs, Xrays and/or MRIs on all patients with plantar heel pain? Just curious.

Thanks Bruce and Kevin.

Kevin I normally follow your example with classifying as dorsal midfoot interosseous compression syndrome when others have ordered CR which showed no significant findings. In recalcitrant cases I always look for evidence of TMT synovitis with US specifically to rule out other issues and identify corticosteroid injection site.

I always do US for plantar heel pain; I have taught my podiatry assistant to do this - a fast, simple, inexpensive way to rule out/confirm plantar fasciosis and also to identify distal plantar fasciosis which I tend to accommodate to avoid compression irritation from foot orthoses.

Please post if anyone needs interpretation of these images which may be unfamiliar and not intelligible.
