Can be used to fit both long and short residual limbs in combination with the 8E44 Transcarpal Hand (not included in the delivery!). The Endoskeletal Adapter allows the use of the Transcarpal Hand as a particularly short and lightweight prosthetic hand with quick-disconnect mechanism for fitting of both long and short residual limbs. Particularly lightweight: compared with a conventional 8E38 System Electric Hand, the weight is reduced by approx. 80 – 100 g (approx. -20 %), depending on size and tube length, without compromising function. In addition, the proximal position of the quick-disconnect mechanism is beneficial to the prosthesis wearer. Particularly short: the shortest version of the Transcarpal Hand with the quick-disconnect mechanism of the Endoskeletal Adapter is as short as 145 mm, whereas the comparable System Electric Hand is 170 mm (= -15%). (We always measure size 7 3/4 with System Inner Hand.) 1 pc. Coding Ring, brown
