The cadaver study showed that the implanted engineering mechanism for attaching multiple tendons to one muscle significantly improved hand function in grasping tasks when compared with the current procedure.

Inspired by advances in robotic hand design, this paper investigates the development of passive, miniature differential mechanisms as implants for attaching muscles and tendons in tendon-transfer surgery. Using cadaver studies, it is shown that the implanted mechanisms lead to better hand function in grasping tasks when compared with current therapies.
