We use robotic and cadaveric hand preparations to evaluate the efficacy of a novel passive implant mechanism in the ECRL-to-FDP transfer tendon-transfer surgery.Compared with directly suturing the donor to recipient tendons, the implant enables passive differential grasp adaptation between the index...
Carpal tunnel syndrome is caused by compression of the median nerve in the carpal tunnel. Division of the transverse carpal ligament is a routine surgical procedure to treat the hand problem. We have developed alternative biomechanical approaches to carpal arch space augmentation by radioulnar wrist...
The hand and wrist represent one of the most challenging structures in the study of biomechanics, as well as in the evaluation of many biomechanical principles. Hand and wrist biomechanics has been somewhat underdeveloped in comparison to mainstream biomechanics research over the past century. While...
The purpose of this topic is to describe how biomechanical studies performed to assess the effects on digital flexor tendons excursion of these minimally invasive procedures in comparison to the classical open approach finally leads to the development of original procedures that are now a days routi...
The origin and current state of the ISG group will be introduced. By reviewing the presentations of the past ISG meetings, general trends of developments will be highlighted. As examples, the three invited speakers will be introduced.
Imaging-based approaches for quantifying joint kinematics and arthrokinematics of joint movement have become more commonplace in the research environment. Both static and dynamic approaches are being utilized to quantify rotation and translation of the shoulder joint complex in global and anatomical...
Hand and wrist anatomy and biomechanics are among the most complex in the musculoskeletal system. Optimal function requires exacting interplay between several uniquely shaped and interdependent bones, articular surfaces, intrinsic and extrinsic ligaments and myotendinous units. Conditions that affec...
The shoulder joint is the most common site of musculoskeletal pain in people with spinal cord injuries who use manual wheelchairs. Current understanding of shoulder pathology in manual wheelchair users points to an etiology related to overuse of the shoulder joint that is not optimized for weight be...
Complex computational shoulder models have been used to investigate and understand the biomechanics of Reverse Shoulder Arthroplasty(RSA), but despite the advancements in knowledge, impingement and limited ROM still remain a concern. To solve the problem, new technologies were introduced (e.g. Patie...
A set of hot-topics will be presented and will serve to stimulate the discussion with the audience. The aim is to agree on a limited number of important innovations for the development and exploitation of shoulder biomechanics.
We analyzed the motion characteristics of a hemiplegic patient reaching on a desk by comparing them with a healthy subject using three-dimensional (3D) motion analysis and electromyogram (EMG). In the hemiplegic subject, joint movement range, motion speed, and motion trajectory were remarkably infer...
MR images of the distal upper limb of four participants were obtained. Participants were braced in 3 different wrist postures (radial deviation, neutral, ulnar deviation), in combination with 3 forearm postures (pronation, mid, supination). The flexor digitorum superficialis (FDS2) and profundus (FD...
