Wrist Configuration - A Study From Computed Carpal Models

Anatomical structures are characteristically nonuniform in shape, a property which confounds efforts to describe their geometries. By imposing the additional constraint of working en vivo, the task is made more formidible due to the difficulty in obtaining accurate measurements using noninvasive means. This paper presents a new approach to describing structural properties of the carpal (wrist) complex based on a collection of 3-D computed models derived from CT scans. A notable feature of the present analysis is that it does not rely on the use of physical markers, unlike the usual approaches to shape classsification.
