The use of myoelectric components to treat amputations and malformations in the transcarpal region was long considered impossible. Until now. Otto Bock has developed unique solutions for treating especially long residual limbs.
Patients with long residual limbs have a myoelectric option with Otto Bock’s 8E44 Transcarpal Hand.
To create a hand as lightweight and compact as possible, we've made the motor 1/3 smaller and repositioned it to take up less room proximally. The result is a hand with the same grip force as comparable adult hands. And to save even more room we've created an innovative new connection technique that uses cable loops instead of a lamination ring. The Transcarpal Hand can be operated with either the DMC plus or Digital Twin control units.
Because many patients with long residual limbs can perform pronation and supination (ulna and radial bones conserved) the relevant joint for this function has been left away.
To make sure as many patients as possible can be fit, we offer three standard sizes (7 ¼, 7 ¾, 8 ¼) in two control variations.
