“…This type of injury is caused by an eccentric overextension of the distal interphalangeal (DIP) joint, as can occur during the forceful release of one player’s grip on another player’s jersey or a finger getting caught on the rim of a basketball hoop, and leads to an avulsion of the connected musculus flexor digitorum profundus (FDP) tendon ( Murphy and Mass, 2005 ; Gaston and Loeffler, 2015 ; Avery et al, 2016 ). This injury has been studied extensively in clinical studies, for example, in the work of Tempelaere et al ( Tempelaere et al, 2017 ), while computational investigations have thus far been focused on the modelling of general hand models ( Joaquin et al, 2011 ), singular digits ( Wu et al, 2008 ; Vigouroux et al, 2009 ; Fok and Chou, 2010 ; Wu et al, 2010 ) or the finger pulley system ( Roloff et al, 2006 ; Vigouroux et al, 2008 ). In the field of automotive safety assessment, finite element (FE) neuromuscular human body models (NHBMs) created for the use with the FE-solver LS-DYNA (Ansys, Canonsburg, PA, United States) such as the Global Human Body Models Consortium (GHBMC) ( Devane et al, 2019 ) or the Total Human Model for Safety (THUMS) ( Kato et al, 2017 ; Kato et al, 2018 ) have been validated and are mainly employed to evaluate a host of different injury types related to car crash scenarios ( GHBMC, 2016 ; Toyota Motor Corporation, and Toyota Central R&D Labs.…”

Introduction: A common hand injury in American football, rugby and basketball is the so-called jersey finger injury (JFI), in which an eccentric overextension of the distal interphalangeal joint leads to an avulsion of the connected musculus flexor digitorum profundus (FDP) tendon. In the field of automotive safety assessment, finite element (FE) neuromuscular human body models (NHBMs) have been validated and are employed to evaluate different injury types related to car crash scenarios. The goal of this study is to show, how such a model can be modified to assess JFIs by adapting the hand of an FE-NHBM for the computational analysis of tendon strains during a generalized JFI load case.Methods: A jersey finger injury criterion (JFIC) covering the injury mechanisms of tendon straining and avulsion was defined based on biomechanical experiments found in the literature. The hand of the Total Human Model for Safety (THUMS) version 3.0 was combined with the musculature of THUMS version 5.03 to create a model with appropriate finger mobility. Muscle routing paths of FDP and musculus flexor digitorum superficialis (FDS) as well as tendon material parameters were optimized using literature data. A simplified JFI load case was simulated as the gripping of a cylindrical rod with finger flexor activation levels between 0% and 100%, which was then retracted with the velocity of a sprinting college football player to forcefully open the closed hand.Results: The optimization of the muscle routing node positions and tendon material parameters yielded good results with minimum normalized mean absolute error values of 0.79% and 7.16% respectively. Tendon avulsion injuries were detected in the middle and little finger for muscle activation levels of 80% and above, while no tendon or muscle strain injuries of any kind occurred.Discussion: The presented work outlines the steps necessary to adapt the hand model of a FE-NHBM for the assessment of JFIs using a newly defined injury criterion called the JFIC. The injury assessment results are in good agreement with documented JFI symptoms. At the same time, the need to rethink commonly asserted paradigms concerning the choice of muscle material parameters is highlighted.

“…For mechanism's kinematics, researches on upper limb locomotion were performed, especially the hand mechanism. The results of investigations accomplished the kinematic chains of mechanism [3] driven by the miniature pneumatic actuators. Concerning the anthropometric hand data, their values are different from a subject to an another, so that mechanism is exclusively conducted dedicated to those who are part of the overall dimensions considered for the component parts of the mechanism.…”

Studies and researches in medical devices made evident the need of new systems and technologies for locomotors recovery of human body as to reduce the reintegration time in normal activities and, not the least, to improve the recovery quality, to give the possibility to perform natural movements identical to those before the suffered injury. Thus, the purpose of this paper is to obtain the 3D virtual model of a mechanism describing the hand kinematics, and a real medical prototype device to be used in locomotors recovery of the hand. In order to perform the movements, pneumatic fluidic actuators are used, considering that they are flexible, small, made especially for this project. A specialized software for assisted design is used to obtain the virtual model and for the fabrication of device component parts Rapid-Prototyping technology is applied, the Fused Deposition Modeling principle (FDM).
