We set limits on the configuration space of the pose parameters in order to automatically generate realistic hand poses using our 3D synthetic hand model. This ensures natural hand configurations mimicking real hand gestures. A comprehensive study on the functional ranges of joint movement is conducted in [3] and [2]. We employ the Type I and II constraints articulated in these papers on our ki...

BACKGROUND The purpose of this study was to determine the feasibility of Roentgen Stereophotogrammetric Analysis (RSA) in total joint arthroplasty of the trapeziometacarpal (TMC) joint of the thumb. METHODS In five cadaveric hands the TMC-joint was replaced by the Surface Replacement Trapeziometacarpal prosthesis (SR™ TMC prosthesis; Avanta, San Diego, CA) and tantalum beads of 0.8 mm were im...

Trapeziometacarpal instability with trapezial dysplasia is a disabling condition long before the radiological changes of osteoarthritis appear. In dysplastic joints surgical soft tissue correction fails to prevent the instability, requiring a correction of the bony anatomy. We combined two techniques described in the past, an abduction osteotomy of the first metacarpal and an opening wedge oste...
