Achilles tendon rupture vestigial muscle is harvested and wrapped around the Achilles tendon, increasing the strength of the repaired tendon. If the tissue quality is poor, e.g. the injury has been neglected, the surgeon might use a reinforcement mesh (collagen, Artelon or other degradable material). In percutaneous surgery, the surgeon makes several small incisions, rather than one large incision, and sews the tendon back together through the incision(s). Surgery may be delayed for about a week after the rupture to let the swelling go down. For sedentary patients and those who have vasculopathy or risks for poor healing, percutaneous surgical repair may be
Tendon-driven robot models and tools for simulation control, data acquisition and system investigation. The Anatomically Correct Testbed robotic hand uses tendons and woven finger extensor hoods to capture the biomechanical properties of the human hand. The tendons slide over 3D printed bones matching human bone shapes, reproducing the variable moment arms and some of the tendon network interactions found in the human hand. The tendons are actuated by direct drive (without gearing), allowing them to spool out freely when other tendons oppose them in the skeleton. Tendon-driven robot Tendon-driven robots (TDR) are robots whose limbs mimic biological musculoskeletal systems. They use plastic
