Dear all,

Just wondering what the current range of opinions is regarding orthotic management of significant flexible and rigid cavo-varus, which corrects the hindfoot to neutral with a Coleman block test (ie FF valgus/RF varus scenario).

Is there any preference for Fettig/Denton/Feehrey modifications or similar.

I seem to never quite get the amount of control I need to correct the hindfoot to neutral when bringing the "ground up" to meet the lateral column...

LuckyLisfranc,
A podiatrist by the name of Joshua Burns has just submitted his PhD on the best orthosis for the pes cavus foot type. I hope Josh will jump in and post, but what he presented at the recent Australasian Podiatry Conf suggested that the pt's faired best with a device that had:

* Modified Root device
* 20% medial arch fill (ie. maximum expansion)
* Lateral heel post (with no taper/grind - almost a lateral heel flare). No posting on the medial side of heel.
* 3mm Poron full length covering + Cashmere
* 12mm heel cup height
* 6mm lat heel expansion (mainly due to the thickness of the poron)
* F/ft width - lateral border of foot to bisection of 1st MPJ
* Length at distal edge was proximal to MPJ's

I am not sure in which publication/s the research is to be submitted, but will post as soon as the details come to hand.

Phil Hartshorne
