C shaped calcaneus and Haglund's deformity

Members do not see these Ads. Sign Up.

Hello,

I remember reading about an association between a c-shaped calcaneus and Haglund's deformity, does anyone know of this and if so know where I might be able to find out a little more about it? Maybe the speaker was referring to a rear foot varus but I distinctly remember him say a c shaped calcaneus.

I really appreciate any help. Thanks!

You are probably talking about Helbing's sign when you talk of a "c-shaped calcaneus". Try googling it.

 

Luke:

I believe that the "speaker" may have been referring to a frontal plane angular deformity of the calcaneus where the plantar half of the calcaneus is more inverted relative to the dorsal half of the calcaneus than normal. This is otherwise known as a calcaneal varus deformity.

 

Thank you for your replies gentlemen.

After talking to my professor, I believe she meant it more as a description of a calcaneus varus and not as any specific, distinguishable type of calcaneal varus.

But while I was researching Haglund's deformity on this topic, I came across some discrepancies regarding it vs a "pump bump". Here's my understanding:

Haglund's deformity:
-either a superficial calcaneal bursitis, retrocalcaneal bursitis, or Achilles tendoenthesopathy.
-A "pump bump" refers to a superficial calcaneal bursitis. Therefore a pump bump is a form of Haglunds but not necessarily vice versa.

Some author's seem to associate the name Haglund's deformity with a pump bump and vice versa. Is my understanding above true or is the name synonymous?

Thank you!
