This report describes a family with bilateral non-opposable triphalangeal thumb, bringing to two the number of families with this autosomal dominant disorder.

This paper investigates thumb-index interaction on touch input devices, and more precisely the potential of two concurrent stroke gestures , i.e . in which fingers same hand concurrently draw one each. We present fundamental studies, using such for two-dimensional control, by drawing figures, other command activation, roughly sketching figures. Results give a first analysis user performance 35 ...

LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Understand the pathomechanical and biochemical basis for thumb trapeziometacarpal joint degeneration. 2. Diagnose and grade trapeziometacarpal joint disease based on presentation, physical examination (including provocative testing), and radiographic evidence. 3. Understand the principles of ligament reconstr...

The thumb plays an important role in hand function. Daily tasks involving pinch, grip, grasp and precise handling are more easily accomplished with an opposable thumb, Loss of thumb diminish much the hand abilities and function [1]. Soft tissue injuries of the hand frequently require flap coverage, either to preserve structures or even to facilitate later reconstruction [2]. The absence of the ...

A rigorous description of the magnitude and direction of the 3D force vector each thumb muscle produces at the thumb-tip is necessary to understand the biomechanical consequences to pinch of a variety of paralyses and surgical procedures (such as tendon transfers). In this study, we characterized the 3D force vector each muscle produces at the thumb-tip, and investigated if these thumb-tip forc...

Previous studies of control of fingertip forces in skilled manipulation have focused on tasks involving two digits, typically the thumb and index finger. Here we examine control of fingertip actions in a multidigit task in which subjects lifted an object using unimanual and bimanual grasps engaging the tips of the thumb and two fingers. The grasps resembled those used when lifting a cylindrical...
