Statistics regarding 3D hand production

[Jaunkalns]

Hello, everyone.
I am currently working on an assignment regarding 3D printed hands (mechanical, myoelectric, robotic), but cannot seem to find any statistics about this topic (approximate count of already produced hands would be the main target). I am fairly new to this field, and would appreciate any help (your findings or maybe there is a website where some information is gathered).
Thank you!

I'm a volunteer with e-NABLE for the past 2 years and we have printed and donated more than 1100 hands. We're probably the largest worldwide movement printing hands and arms on 3D printers. Google gave us a grant for $600,000 a few months ago and we announced plans to print 6000 hands by 2017.
Check out www.enablingthefuture.org for information. The original 3D printed hand was the Robohand designed and built by Ivan Owen and Richard Van As. Ivan is a founding member of e-NABLE and Richard still runs Robohand. I have a group on LinkedIn working to design and print lower limb prosthetics now.
