Abstract : The long-term goal of this research is to advance orthopedic surgery by designing implantable, miniature, passive mechanisms, such as artificial insertable rods and tendon networks, for enhancing the functional attachment of muscle to tendon(s) and bone and creating superior and customizable movement and force transmission. The specific object goal of this work is to design, fabricate, and validate a biocompatible implantable mechanism that enables the surgical construction of a differential mechanism using existing biological tendons in order to improve the routing of forces and movements between muscle and tendons in the tendon-transfer surgery for high median-ulnar nerve trauma. The key findings in this period relating to the project goals are as follows: 1) The mechanical effect of the implant on the muscle-tendon biomechanics has been validated. 2) Progress in implant design fand abrication is excellent. 3) Preliminary development and validation of non-fouling coatings for the implant has been completed.
