To assess the biomechanical stability relative to screw length and K-wire augmentation in scaphoid fracture fixation using a flexibility testing protocol and cadaver scaphoids whose soft tissue attachments remained undisturbed. Our hypothesis was 2-fold: increasing screw length and augmenting fixation with a K-wire would improve fracture fragment ...

Analytica Chimica Acta, 2019
For the first time, a rapid, efficient, simple, and inexpensive approach for solid phase microextraction on a screw (MES) was developed. MES is a miniaturized form of solid-phase extraction without any backpressure. In this system, analytes were adsorbed on the surface of micro channels of a screw that was coated by polypyrrole (PPy).

Proceedings of the Institution of Mechanical Engineers, 1951
The paper describes the various commercial methods of producing screw threads by cutting, rolling, grinding, and milling. The operating principles on which the several processes depend are dealt with and their advantages and limitations are discussed. A workshop method of determining the torque required for tapping and for threading is described, and

On Displacing a Screw about a Screw
2002We derive, using compact vector methods which do not rely on Kotel’nikov’s principle, the dualised “Rodrigues formula” which is a well-established expression for the screw that has suffered a screw displacement from a known initial location. An alternative perception — that the screw has suffered rigid-body rotation through a dual angle — is examined ...
