im a 3rd year podiatry student and just have a *stupid* question that i wanted to ask about orthoses to you podiatrists .
(this is for a semi rigid modified root )
When making an "intrinsic rearfoot posting heel grind at 0 degrees", i would have to grind the positive cast is ground flat at the heel.
The dilemma is this - How much DO i grind ??? i mean its already at 0 degrees when i put that nail in the bisection of the 1st MTPJ and made the anterior platform. do i grind down so that theres a 10mm squared flat area? or grind it down by 3 mms? how does it work??
any help would be appreciated!
thanks in advance!
