Ulnocarpal impaction syndrome involves excessive loading of the ulnocarpal joint. Ulnar shortening osteotomies are an effective way to reduce ulnocarpal loading but alter contact mechanics at the distal radioulnar joint (DRUJ). This study used a computational model to investigate the relationship between ulnar length and DRUJ mechanics. Detailed, finite(More)
All existing moment arm data for muscles of the forearm derive from tendon excursion experiments. Moment arms determined this way are only valid for movement about the same generalised coordinate system as was used during the tendon excursion, which makes their implementation in more complex or realistic joint models problematic. This study used a(More)
This axis of radius rotation is widely employed in forearm rotation research, yet there are relatively few studies that have attempted to validate its position and proposed consistency. Studies that have reported a consistent radius axis have not considered sequential finite rotations – instead, they’ve calculated average axes over a large range of motion(More)
Distal radius malunion is a problem that is common to distal radius fractures and can affect the contact mechanics of the distal radioulnar joint (DRUJ). The goal of this study was to use a computational model of the DRUJ to investigate the influence distal radius orientation has on its contact mechanics. Detailed, finite element models of the radius and(More)
Physiological cross-sectional area (PCSA) is a very important parameter for modeling muscle force. Most studies utilize cadaveric data when doing so, however, it is not known how appropriate this is for forearm muscles. In this study, the volumes of four forearm muscles were determined using 3D parametrized (finite element) models created with the data(More)
A cross-sectional reliability study was conducted with 23 normal participants to establish normal values, and the repeatability and validity of distal radioulnar joint translation measurements using ultrasound imaging. Static transverse images of maximal supination, neutral and maximal pronation were examined to assess translation, using a method consistent(More)
