Hi Tony

Regarding the CAD comments, I have been using CAD for about 18 months

and have found that it is exceptionally quick, about 40 minutes from the

time I start casting to having a positive mould, and that is without

rushing. I also believe that it is more accurate that plaster because

the practioner can convert their hand skill with plaster directly onto

the residual limb without the plaster masking the underlying anatomy. I

still take all relevant measurements and check with the digitised

measurements that they correspond.

As they say the proof is in the pudding and my first fit success rate is

up around 50%. Some basic stats in our facility are that with plaster we

where getting around 60% first time fit ( with copolymer check sockets)

with CAD this has increased to 90%. So not only has our speed improved

but also the wastage. Another positive is that more time is spent with

the patient and they can see the work that is being done on the

computer, they also enjoy the extra interaction and the added education.

The CAD systems have their limitations and do not replace plaster


Best wishes
