Above the Elbow Limb Difference


Sherri is a talented artisan, accountant and mother who is passionate about working with her hands. She began using a body-powered prosthetic arm when she was a child and has relied on a myoelectric arm for 40+ years. Sherri works closely with an upper limb specialist to achieve optimal fit and function without having to wear a harness. She appreciates how her prosthesis supports her active life.

Prosthesis Details

  • Myoelectric prosthesis with a Dynamic Arm and Variplus Speed hand

  • Adjustable custom socket designed to support the bone lengthening procedure she had on her residual limb to improve suspension and control of her arm—a truly unique option for someone with a transhumeral limb difference

  • Activity-specific prosthesis with Ergo Arm and passive hand for bike riding

"The prosthesis dramatically lessens the burden that I have on my left hand. It helps to balance me out on the right and helps with some of the fine motor skills I do at my desk."
