STUDY DESIGN A retrospective cross-sectional study. PURPOSE The purpose of this study is to evaluate the accuracy and safety of free-hand pedicle screw insertion performed by a young surgeon. OVERVIEW OF LITERATURE Few articles exist regarding the safety of the free-hand technique without inspection by an experienced spine surgeon. METHODS The index surgeon has performed spinal surgery fo...

Data security and personal privacy are difficult to maintain in the Internet age. In 2012, professional networking site LinkedIn suffered a breach, compromising the login of over 100 million accounts. The passwords were cracked and sold online, exposing the authentication credentials millions of users. This manuscript dissects the cryptographic failures implicated in the breach, and explores mo...

OBJECTIVE To identify the accuracy and efficiency of the computed tomographic (CT)-based navigation system on upper cervical instrumentation, particularly C1 lateral mass and C2 pedicle screw fixation compared to previous reports. METHODS Between May 2005 and March 2014, 25 patients underwent upper cervical instrumentation via a CT-based navigation system. Seven patients were excluded, while ...

In Ohio, the principle of confidentiality embodied in the Hippocratic Oath is more than an ethical principle espoused by the medical profession.' For physicians licensed to practice within this state, by virtue of Section 4731.22 of the Ohio Revised Code, the principle is a legal obligation, the breach of which may subject the practitioner to disciplinary action up to and including revocation o...

Noise can be a unique probe of electron–electron correlations in nanoscale electron devices. While stationary or small signal transport can often be simply understood in terms of single particle behaviour, noise can be extremely sensitive to many-body effects (Landauer L 1996 Physica B 227 156). We present a new collective phenomenon emerging in electron transport in a resonant tunnelling diode...

BACKGROUND The aim of this study was to review the typical factors related to physician's liability in obstetrics and gynecology departments, as compared to those in internal medicine and surgery, regarding a breach of the duty to explain. METHODS This study involved analyzing 366 medical litigation case reports from 1990 through 2008 where the duty to explain was disputed. We examined relati...

This article focuses on cases of restitution within contract, investigating the normative desirability of enabling a promisee to pursue the profits derived by the promisor through a breach of contract as an alternative pecuniary remedy of wide applicability. Situated at the frontier of both contractual and restitutionary liability, the question of whether restitutionary damages for breach of co...

BACKGROUND Pedicle screws are used increasingly in spine surgery. Concerns of complications associated with screw breach necessitates accurate pedicle screw placement. Postoperative CT imaging helps to detect screw malposition and assess its severity. However, accuracy is dependent on the reading of the CT scans. Inter- and intra-observer variability could affect the reliability of CT scans to ...
