The reporting of adverse events (AEs) in randomized clinical trials (RCTs) is often lacking in the publication of trials. Part of the problem is the way safety data are reported in RCTs. Reporting of "time to event," use of standardized incidence ratios for comparison to normal population or disease controls, ...
Yazici, Hasan - - 2009
The current understanding that disease criteria are different than classification criteria is not well founded. In fact, they are a continuum. The arithmetic behind the two are the same and is built on a clear understanding of the concepts of sensitivity and specificity. Diagnosis is nothing different than classification in ...
Tanjong-Ghogomu, Elizabeth - - 2009
Providing evidence-based care to patients involves turning a clinical problem into an answerable question, systematically searching for the best evidence relevant to the question, critically appraising that evidence, and, finally, using the evidence as the basis for clinical decisions to solve the problem. While the overload of medical information today ...

Large diameter metal-on-metal hip bearings have proven to be clinically successful in active patients, but, in a small number, they are associated with elevated wear and high metal ion levels when cup inclination angles are too steep and the version is too extreme, or either alone. Based on the geometry ...
Hallab, Nadim - - 2009
Biologic response to orthopedic implants debris is central to clinical performance. Eventual implant loosening due to aseptic osteolysis has been attributed to local inflammatory responses to wear and corrosion products that are produced by articulating implant interfaces. The response to implant debris is dominated by local immune activation, e.g. macrophages. ...
Duff, Michel J. - - 2009
Range of motion after total hip arthroplasty is becoming an important topic as today's patients present at a younger age and are more active. An effective study design to carry out comparisons of clinical performance between two implants should eliminate patient-related extraneous variables (e.g., age, gender, activity level, among others). ...
Ball, Scott - - 2009
Introduction: The recent, encouraging outcome literature on hip resurfacing arthroplasty (HRA) has not sufficiently examined the potential occurrence of postoperative femoroacetabular impingement (PFAI) and sequelae. The current study asks the questions, "Does femoroacetabular impingement occur after hip resurfacing arthroplasty (HRA) and, if so, what are the clinical outcomes?"
Nikolaou, Vassilios - - 2009
Evaluation and treatment of pain following hip resurfacing arthroplasty can be challenging, even for the most experienced arthroplasty surgeon. As in any total hip replacement, there are a number of investigative tools at the disposal of orthopaedic surgeons to elicit the underlying causes of pain for diagnosis and treatment. A ...
Shields, John - - 2009
Hip resurfacing arthroplasty is a technically challenging procedure, and orientation of the femoral component is critical to avoid implant failure. The use of computer-assisted navigation has been shown to decrease the learning curve for beginners in hip resurfacing and to improve the surgeon's ability to produce consistent results. Computer navigation ...
Olsen, Michael - - 2009
Hip resurfacing is a technically demanding alternative to total hip arthroplasty. The use of traditional jigs for placement of the femoral guidewire can lead to preparatory errors that may predispose the resurfacing construct to premature failure. Computer navigation is a tool that can be used to minimize the incidence of ...
