Ultrasound visualization of the thumb annular pulleys: A cadaveric validation study.

Background: The thumb annular pulley system is unique from the other digits and is integral to normal thumb function. Injuries to this pulley system can present a diagnostic challenge. No prior study has evaluated the ability of ultrasound (US) to evaluate all four thumb pulleys.

Melding Vapor-Phase Organic Chemistry and Textile Manufacturing To Produce Wearable Electronics.

Body-mountable electronics and electronically active garments are the future of portable, interactive devices. However, wearable devices and electronic garments are demanding technology platforms because of the large, varied mechanical stresses to which they are routinely subjected, which can easily abrade or damage microelectronic components and electronic interconnects. Furthermore, aesthetics and tactile perception (or feel) can make or break a nascent wearable technology, irrespective of device metrics.

Towards seamlessly-integrated textile electronics: methods to coat fabrics and fibers with conducting polymers for electronic applications.

Traditional textile materials can be transformed into functional electronic components upon being dyed or coated with films of intrinsically conducting polymers, such as poly(aniline), poly(pyrrole) and poly(3,4-ethylenedioxythiophene). A variety of textile electronic devices are built from the conductive fibers and fabrics thus obtained, including: physiochemical sensors, thermoelectric fibers/fabrics, heated garments, artificial muscles and textile supercapacitors. In all these cases, electrical performance and device ruggedness is determined by the morphology of the conducting polymer active layer on the fiber or fabric substrate.

Precontoured parallel plate fixation of AO/OTA type C distal humerus fractures.

Objectives: To determine the clinical effectiveness of precontoured parallel plating for the management of Orthopaedic Trauma Association (OTA) type C distal humerus fractures.

Design: Retrospective case series.

Setting: Level I trauma center.

The economic impact of electric saw injuries to the hand.

Purpose: Injuries from electric saws cause considerable hand trauma. This study is designed to provide information detailing the costs of these injuries.

Methods: The study was performed in a tertiary referral academic medical center.
