Creating the perfect partial hand prosthesis is challenging. All residual limbs are unique in one way or another. However, partial hands are especially complex because they may involve anywhere from one to five residual fingers and/or a partial palm.
Both the structure and degree of muscle control in the residual hand may dictate or limit possible solutions. In any event, a custom socket will almost certainly be required.
Below, you will find brief descriptions and links to more detailed articles on all the most advanced partial hand technologies currently available.
Nearly 2/3 of upper limb amputations involve finger or partial hand loss. Ossur’s i-Digits line of products provides one of the few bionic options to meet this need. Based on i-Limb technology, i-Digits offers myoelectric control over anywhere from 1 to 5 bionic digits.
Partial hand amputations account for nearly 2/3 of all upper limb amputations. Bionic partial hand prostheses are ideal for these situations, but they’re also very expensive. Hi-tech body-powered and ratcheting mechanical prostheses, by comparison, are much more affordable.
