Clinical trials and meta-analyses have suggested that aspirin may be effective for the prevention of venous thromboembolism (proximal deep-vein thrombosis or pulmonary embolism) after total hip knee arthroplasty, but comparisons with direct oral anticoagulants are lacking prophylaxis beyond hospital discharge.
Most assessment of surgical trainees is based on measures knowledge, with limited evaluation their competence to actually perform various procedures. In this study, the authors evaluated a tool they designed assess trainee's an entire procedure independently, regardless type or postgraduate year (PGY).In phase 1, Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) was piloted in University Ottawa's Division Orthopaedic Surgery. 2, refined 11-item (8 items rated 5-point competency...
The role of aspirin in thromboprophylaxis after total hip arthroplasty (THA) is controversial.To compare extended prophylaxis with and dalteparin for prevention symptomatic venous thromboembolism (VTE) THA.Multicenter randomized, controlled trial a noninferiority design based on minimal clinically important difference 2.0%. Randomization was electronically generated; patients were assigned to treatment group through Web-based program. Patients, physicians, study coordinators, health care...
Postgraduate medical education is an essential societal enterprise that prepares highly skilled physicians for the health workforce. In recent years, PGME systems have been criticized worldwide problems with variable graduate abilities, concerns about patient safety, and issues teaching assessment methods. response, competency based approaches, emphasis on outcomes, proposed as direction 21st century profession education. However, there are few published models of large-scale implementation...
The iconic Miller’s pyramid, proposed in 1989, characterizes 4 levels of assessment medical education (“knows,” “knows how,” “shows “does”). frame work has created a worldwide awareness the need to have different approaches for expected outcomes and training. At time, Miller stressed innovative use simulation techniques, geared at third level (“shows how”); however, “does” level, workplace, remained largely uncharted area. In 30 years since conference address seminal paper, much attention...
Many patients undergo both THA and spinal arthrodesis, those may not fare as well who one procedure but the other. The mechanisms of how arthrodesis affects patient function after remain unclear.The aims our study were to (1) determine patient-reported outcome measures (PROMs), including Oxford hip score dislocations complications compare between with without arthrodesis; (2) characterize sagittal pelvic changes in these that occur when moving different functional positions test for...
Traditional approaches to assessment in health professions education systems, which have generally focused on the summative function of through development and episodic use individual high-stakes examinations, may no longer be appropriate an era competency based medical education. Contemporary programs should not only ensure collection high-quality performance data support robust decision-making learners' achievement competence but also facilitate provision meaningful feedback learners...
Construct: The Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) is a 9-item surgical evaluation tool designed to assess technical competence in trainees using behavioral anchors. Background: initial development of the O-SCORE produced evidence for valid results. Further work required determine if use single surgeon or an unblinded rater introduces bias. In addition, relationship other currently used assessment tools should be explored provide validity related measures. We have...
Background: Fully immersive virtual reality (VR) uses headsets to situate a surgeon in operating room perform open surgical procedures. The aims of this study were determine (1) if VR curriculum for training residents anterior approach total hip replacement (AA-THR) was feasible, (2) enabled residents’ performance be measured objectively, and (3) cognitive motor skills that learned with use transferred the physical world. Methods: 32 orthopaedic (surgical postgraduate years [PGY]-1 through...
The number of revision total knee replacements continues to increase annually. To date, much the literature has focused on performance titanium systems. primary aim current study was review mid term results a contemporary system, with alternative design features. Ninety-one consecutive patients having aseptic arthroplasty one, modular all-cobalt chrome stemmed system using hybrid stem fixation were studied prospectively. Eighty-nine revisions in 84 reviewed at mean 5.9 years (range, 4.1–8.6...
Aims This study aims to: determine the difference in pelvic position that occurs between surgery and radiographic, supine, postoperative assessment; examine how influences subsequent component orientation; establish whether differences position, thereafter orientation, exist total hip arthroplasties (THAs) performed supine versus lateral decubitus positions. Patients Methods The intra- anteroposterior radiographs of 321 THAs were included; 167 with patient using anterior approach 154...
The management of intra-articular distal humeral fractures remains a difficult surgical problem. Although an olecranon osteotomy provides excellent exposure for these fractures, number complications can occur after the creation and repair including nonunion, malunion, hardware failure, pain secondary to prominent hardware. In effort reduce incidence complications, senior authors now use contoured 3.5 mm reconstruction plates fixation their apex-distal chevron osteotomies. Two surgeons at...
A new family of micro-posterior approaches, percutaneously assisted total hip (PATH), SuperCapsular (SuperCap) and Supercapsular (SuperPATH) allow preservation the short external rotators. This study assesses early outcomes learning curves PATH SuperPATH approaches.Early first consecutive 49 50 cases performed by a non-developer surgeon were evaluated. Analysis variance (ANOVA) was used to compare age, body mass index (BMI), pre-operative hemoglobin. Gender compared using Chi-square test....
Recent studies have reported nearly 40% of costs associated with a 30-day episode-of-care for total joint replacements are due to post-discharge activities and 81% those specifically unplanned readmissions discharging patients post-acute care facilities. The purpose this study was determine these two key variables hip arthroplasty (THA) implanted using tissue-sparing surgical technique see how values compare previously in the United States.The healthcare databases at three institutions were...
Proximal humerus fractures are the third most common fracture in elderly population and expected to increase due aging population. Surgical fixation with locking plate technology has increased over last decade despite a lack of proven superiority literature. Three previous randomized controlled trials have not shown difference patient-centered outcomes when comparing non-operative treatment open reduction internal fixation. Low patient enrollment other methodological concerns however limit...
