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...

38 Objective: The purpose of this study was to investigate altered finger-thumb coupling in 39 individuals with chronic hemiparesis post-stroke. 40 Methods: First, an external device stretched finger flexor muscles by passively rotating the 41 metacarpophalangeal (MCP) joints. Subjects then performed isometric finger or thumb force 42 generation. Forces/torques and electromyographic (EMG) signa...

It is the intent of this article to describe, compare and contrast the usual form of the trait for polydactylism in cats especially in Maine Coon Cats. The usual form of polydactyly will be defined as the trait commonly seem in Maine Coon Cat especially those familiar to organizations such as Mcpolys (http://www.mcpolys.com) This discussion will show that the usual gene for polydactylism is har...
