What are the most recent accomplishments in the field of amputations and artificial limbs?

Prosthetic legs: There are big improvements in the artificial legs. They are lighter, easier to put on and take off. They are easier to adjust; still expensive. The rehab doctors are more aggressive in getting amputee patients into a prosthetic limbs. On the surgery/amputation side surgeons are perhaps better at recommending or offering amputation as option/alternative to revascularization.

Control mechanisms: A lot of recent research has concentrated on finding ways to better control artificial arms. Some researchers are working to use the nerves left in the arm to control the prosthesis (targeted muscle reinnervation- tmr) others on using the brain signals to control the prosthesis. Sounds sci-fi but it is not these days! tmr trained physicians are doing surgeries at various centers in the us.
