I've read that callous patterns are associated with certain foot deformities. My questions are:

Is it possible to get an idea of what foot pathology someone has just by looking at someone's callous?

also certain conditions e.g. Hallux limitus result in different callous patterns in different patients:is this related to different aetiologies or compensatory mechanisms? Or both aetiologies and compensatory mechanisms?

Are there any good papers/other resources on callous pattern?

If you search under 'EFULLER' as the 'username' in 'Advanced Search' in this website you'll get some GOOD advice re same, Dr Fuller has posted several times on callus, mark

 

When you are asking about foot pathologies are you asking about forefoot to rearfoot relationship or are you asking about something like 2nd metatarsal stress fractures?

When you mention compensatory mechanisms are you asking about motion caused by a "foot deformity" or are you talking about altered muscle firing patterns that occur when people walk differently to avoid pain (limping)?

There was a paper by Peter Cavanagh that looked at x-ray measurements vs plantar pressures. Yes, long 2nd met did correlate with high pressure sub 2nd met head. There was another paper that showed that there were high pressures where the calluses are. It may have been by the same author as the paper that Simon pointed you toward.

Thank you to everyone who responded to my question so far.

In response to Dr Fuller's points of clarification:

1) When talking about pathologies I am talking about the second type i.e. 2nd metatarsal stress fracture and other common pathologies such as common 1st MTPJ pathologies, plantar fasciitis and PTTD.

2) In terms of compensatory mechanisms I am talking about the second type i.e. altered muscle firing patterns. Compensatory mechanism: ways patient modify their gait to compensate for example for reduced MTPJ movement or avoidance of pain.

 

I don't know if there is a paper confirming it, but my clinical observation is that the "pinch" callus at the hallux IPJ does correlate pretty well with Windlass related pathology. Windlass pathology is hallux valgus, hallux limitus/rigidus, and plantar fasciitis.

Thanks. Any other clinical observations wrt to callous and certain pathologies? Or even papers that correlate pathologies with callous in certain areas?
