Podiatry Classifications – Mnemonics, vignettes, easy ways to remember

The following is a table of common podiatry classifications. They do not describe the classification in detail, but serves    …..as a stepping stone. It is paramount that you first know what the system describes.


How to remember
Jahss  (1st MPJ dislocation) “JahSeS-amoid”
Watson-Jones (navicular) “Watsaw [the] navicular”
Rowe (calcaneus – extraarticular) “go out and Rowe [your boat] in the Essex river”

the calcaneus looks like a boat too! out = extraarticular, in = intraarticular.

Essex-Lopresti (calcaneus – intraarticular) “see above.”

Out of the types of calcaneal classifications (Rowe, Sanders, Essex-lopreseti) it has TWO words=> 2 types of essex-lopresti

Bernt-Hardy (talar dome lesions) “talar dome lesions are hard to see”

talar dome lesions are commonly missed on normal radiographs (50%)

Lauge-Hansen (ankle fx) “Large-hansen”

refers to ankle fractures! the ankle is large compared other classifications. you prob. should know this classification anyways.

Hardcastle (lis-franc) “queen lis-abeth [and king frank] lives in a castle. ”

if you remember the above, then you can associate QUENU (sounds like queen with this classification. recall that hardcastle elaborated on quenu)

the met's look like a castle's gate
the met’s look like a castle’s gate
Sanders (CT calcaneus) “FEEL THE BERN…from the CT machine”

CT would most likely be used for intra-articular fractures, so this is an intra-articular classification, for the calcaneus. Say it with me: Feel the bern of the coronal CT of the calcaneus –lol?

Danis-Weber (fibula fx) Danis-Weber goes with Salter-Harris. Remember the ABCDanis -Weber. Visualize three locations (A,B,C) with respect to the ankle mortise. Since the mortise involves the tibia, these fractures have to be wrt the FIBULA.
Salter-Harris (tibia fx) See above. S-same SalTEr- TIBIAL EPIPHYSEALradiopaedia.
