Hi nice meet you welcome
Not me pesonally but my dear husband had the very same Taylor spatial frame fitted 2006 for correction of 3 things Ankle,forefoot and arches.
due to a form a form of muscular dystrophy,he had this done.if you wish to chat more i can email you.
he does have Arthritis in ankles now but not RA form.
he did every well and got excellent correction result from this frame.
much better than old technique or breaking and putting in plaster.
hes now able play badminto work full time and at some point will have his other foot done same procedure.
his was done at Kings london.
They call to nras would be great for you speak with RA paitent who had same thing.
all very best
