Variability and reliability of 2-dimensional vs. 3-dimensional glenoid version measurements with 3-dimensional preoperative planning software.

Background: Preoperative planning for total shoulder arthroplasty (TSA) may change according to the measured degree of glenoid version. Both 2-dimensional (2D) and 3-dimensional (3D) computed tomographic (CT) scans are used to measure glenoid version, with no consensus on which method is more accurate. However, it is generally accepted that 3D measurements are more reliable, yet most 3D reconstruction software currently in clinical use have never been directly compared to 2D.

Intersurgeon and intrasurgeon variability in preoperative planning of anatomic total shoulder arthroplasty: a quantitative comparison of 49 cases planned by 9 surgeons.

Background: Preoperative planning software is widely available for most anatomic total shoulder arthroplasty (ATSA) systems. It can be most useful in determining implant selection and placement with advanced glenoid wear. The purpose of this study was to quantify inter- and intrasurgeon variability in preoperative planning of a series of ATSA cases.

Assessment of surgeon variability in preoperative planning of reverse total shoulder arthroplasty: a quantitative comparison of 49 cases planned by 9 surgeons.

Background: Preoperative planning software is gaining utility in reverse total shoulder arthroplasty (RTSA), particularly when addressing pathologic glenoid wear. The purpose of this study was to quantify inter- and intrasurgeon variability in preoperative planning a series of RTSA cases to identify differences in how surgeons consider optimal implant placement. This may help identify opportunities to establish consensus when correlating plan differences with clinical data.

Ethnoveterinary remedies used in the Algerian steppe: Exploring the relationship with traditional human herbal medicine.

Ethnopharmacological Relevance: Ethnoveterinary medicine is vastly under-documented, especially in North Africa, where livestock care is increasingly medicalised. Despite evidence of the interdependence of ethnoveterinary practices and ethnomedicine for human care, the overlap between these two systems and the possible drivers of similarity are rarely addressed in ethnopharmacological literature. Here, we present the first quantitative comparison of remedies used to treat human and animal health among a pastoral society.

Framing health inequalities for local intervention: comparative case studies.

This article explores how health inequalities are constructed as an object for policy intervention by considering four framings: politics, audit, evidence and treatment. A thematic analysis of 197 interviews conducted with local managers in England, Scotland and Wales is used to explore how these framings emerge from local narratives. The three different national policy regimes create contrasting contexts, especially regarding the different degrees of emphasis in these regimes on audit and performance management.

Do general practice characteristics influence uptake of an information technology (IT) innovation in primary care?

Introduction: Recent evaluations of IT innovations in primary care have highlighted variations between centres and practices in uptake and use. We evaluated whether structural characteristics of a general practice were associated with variations in use of a web-based clinical information system underpinning a Managed Clinical Network in diabetes, between the years 2001 and 2003.

Methods: Using a computerised audit trail, we calculated the numbers of web-based operations that occurred in each practice, stratified by staff type and year, and adjusted for the numbers of registered diabetic patients.

Chitosan-coated stainless steel screws for fixation in contaminated fractures.

Stainless steel screws and other internal fixation devices are used routinely to stabilize bacteria-contaminated bone fractures from multiple injury mechanisms. In this preliminary study, we hypothesize that a chitosan coating either unloaded or loaded with an antibiotic, gentamicin, could lessen or prevent these devices from becoming an initial nidus for infection. The questions investigated for this hypothesis were: (1) how much of the sterilized coating remains on the screw with simulated functional use; (2) is the unloaded or loaded chitosan coating bacteriostatic and biocompatible; and (3) what amount and rate does an antibiotic elute from the coating? In this study, the gentamicin eluted from the coating at a detectable level during 72 to 96 hours.
