  • Webinar: Miniature Implants for Hand Tendon-Transfer Surgery

    The OpenSim Project and the National Center for Simulation in Rehabilitation Research (NCSRR) at Stanford invite you to join our next webinar, featuring Ravi Balasubramanian from Oregon State University.

    Title: Miniature Implants for Hand Tendon-Transfer Surgery: A Simulation- and Experiment-Based Study
    Speakers: Ravi Balasubramanian, Oregon State University
    Time: Thursday, October 17 at 9:30 a.m. Pacific Daylight Time

    Tendon-transfer surgeries are commonly performed for a variety of conditions such as stroke, palsies, trauma, and congenital defects. The surgery involves re-routing a tendon from a nonfunctioning muscle to a still-functioning muscle to partially restore lost function. However, a fundamental aspect of the current surgical procedure, namely the suture that attaches the tendon(s) to the muscles, leads to poor hand function in physical interaction tasks such as grasping, because of the fixed 1:1 coupling the suture produces between the muscles and tendons. My group is investigating the use of passive differential engineering mechanisms, such as hierarchical pulleys, as implants to attach the muscles and tendons in place of the direct suture. I will present results from simulations in OpenSim and cadaver experiments that show that the modified surgical procedure results in better hand function in grasping tasks.

    Participation is free, but you must register in advance. We also ask that you join the webinar 5 minutes early to orient yourself to the webinar interface.
