Accuracy of a dynamic surgical guidance probe for screw insertion in the cervical spine: a cadaveric study
© 2016, Springer-Verlag Berlin Heidelberg. Study design: A fresh frozen cadaver study was conducted. Objective: To report the cortical breach rate using the dynamic surgical guidance (DSG) probe versus traditional freehand technique for cervical lateral mass, cervical pedicle and cervical laminar screws. Methods: Nine male fresh frozen cadaveric torsos were utilized for this study. Each investigator was assigned three specimens that were randomized by fixation point, side and order of technique for establishing a screw pilot hole. The technique for screw hole preparation utilized was either a DSG probe in the “on” mode or in the “off” mode using a freehand technique popularized by Lenke et al. Levels instrumented included C1 lateral mass, C2 pedicle screws and lamina screws, and C6–T1 pedicle screws. Fluoroscopy and other navigational assistance were not used for screw hole preparation or screw insertion. All specimens were CT imaged following insertion of all screws. A senior radiolog

Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations Churochkin, Dmitry; Lund Plantat, Fernando (Elsevier, 2017)We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...
Pino Manresa, Manuel del; Musso, Mónica; Pacard, Frank (2012)We study entire solutions of the Allen-Cahn equation which are defined in the 3-dimensional Euclidean space and which are invariant under screw-motion. In particular, we discuss the existence and non existence of nontrivial ...
Fariña Sirandoni, Rodrigo; Hinojosa, Andrés; Sánchez, Martín; Olate, Sergio (Lippicott Williams & Wilkins, 2015)There are 2 types of distraction devices for mandibular distraction: buried and external. The advantage of buried devices is the stability, but the difficulty in removing the screws is the greatest disadvantage. To resolve ...
