In your practices and in residency training, do you follow more of Merton Root, DPM or Edward Glaser, DPM when it comes to podiatric biomechanics/pathomechanics cases of the foot and ankle? Or combination of both? Thanks all.

I am firmly in the Root camp. I read his book a couple of times (and Valmassy's) and am intrigued by his theories.
Please remember that everything we discuss within the Biomechanical realm is theory. There has been no firm proof that can be cited to solidify either as THE theory, so it's a matter of your understanding and whether your brain can wrap itself around one vs. the other. We can argue which is better all we want, but until we have a way of measuring bone angles during full motion gait accurately, all we can do is theorize.
What I've been waiting for for years is a way to do full motion studies using an MRI type device during gait. Even the best F-Scans in the world have to "guesstimate" and at one time there was a device that measured CT scans at various positions of the foot (on a table, not in full stance) and then algorithmically theorized where the bones "should" be with regard to the previous and next position shown on the CT. It was a neat little device but was hardly accurate enough to really prove or disprove one theory vs. the other.
That's just me though.
Apparently birdieDPM has issues with "one" of the doctors you mentioned above. I can tell you that although my feelings are not as strong, Glaser's theories certainly haven't been around long enough for most doctors to have implemented them for a long time, and I'm not sure they are taught in the schools. I know some docs who are intrigued by some of Glaser's thoughts, but I'm not convinced yet.
Admittedly, biomechanics is not my strongest asset, though you certainly have to have a decent concept to perform surgery successfully. So, at this point I would say I'm in Root's camp.
But I'm not sure what you mean by your third choice when you ask if we follow the prinicples of allopathic/MD orthopedists. There are consistencies among both professions.
I post the rearfoot with a 7.3 mm screw across the sub-talar joint. Biomechanics Podfather style LOL.

Does Valmassy follow the Root school of thought in his textbook on foot and ankle biomechanics/pathomechanics? Or did Valmassy expand more on Root's ideas with more of his own? Thanks,
I am reading Root's chapter on Forefoot pathologies due to abnormal pronation. Great read, easy to follow. He states things multiple times in multiple styles so it really sticks. I have read some of Valmasseys book, but I definitely like Root better now.
