Background: Periprosthetic joint infection (PJI) remains a dreaded and unpredictable complication after total hip arthroplasty (THA). In addition to causing substantial morbidity, PJI may contribute long-term mortality risk. Our objective was determine the risk associated with following THA.

Overlapping surgery, also known as double-booking, refers to a controversial practice in which single attending surgeon supervises 2 or more operations, different operating rooms, at the same time.To determine if overlapping surgery is associated with greater risk for complications following surgical treatment hip fracture and arthritis.This was retrospective population-based cohort study Ontario, Canada (population, 13.6 million), years 2009 2014. There 1 year of follow-up. This encompassed...

Background: Although the prevalence of displaced femoral neck fractures in elderly population is increasing worldwide, there remains controversy as to whether these injuries should be managed with hemiarthroplasty or total hip arthroplasty. arthroplasties result better function, they are more expensive and may have higher complication rates. Our objective was compare rates health-care costs between arthroplasty for population. Methods: A population-based, retrospective cohort study performed...

Objectives: To measure time to flap coverage after open tibia fractures and assess whether delays are associated with inpatient complications. Design: Retrospective cohort study. Setting: One forty level I II trauma centers in Canada the United States. Patients/Participants: Adult patients (≥16 years) undergoing surgery for (1) an (including ankle) fracture (2) a soft-tissue during their index admission between January 1, 2012, December 31, 2015, were eligible inclusion. Exposure: Time from...

Establish baseline rates of and risk factors for reoperation within 1 or 2 years ankle open reduction internal fixation (ORIF).Retrospective, population-based cohort study.Two hundred two hospitals in Ontario, Canada (approximate population 13.6 million 2014).Forty five thousand four forty-four patients who underwent ORIF performed by 710 different surgeons between January 1, 1994, December 31, 2011.Intermediate-term because isolated implant removal, repeat ORIF, irrigation debridement (I&D)...

Background: Waiting for hip fracture surgery is associated with complications. The objective of this study was to determine whether waiting health-care costs. Methods: We conducted a population-based, propensity-matched cohort patients treated between 2009 and 2014 in Ontario, Canada. primary exposure early surgery, performed within 24 hours after arrival at the emergency department. outcome direct medical costs, estimated each patient 2013 Canadian dollars, from payer perspective. costs...

Sensory functional MRI was performed in seven normal volunteers at 1.5 T using a vibratory stimulus applied to the pad of first finger left hand. The data normalized standard atlas, and individual group statistical parametric maps were computed. Robust bilateral activation demonstrated secondary somatosensory cortex (SII), indicating representation SII humans. Greater maxima volumes achieved contralateral as compared SI. fMRI can provide sensitive assay for probing nature function vivo.

Background: Given single-institution studies showing trends between after-hours hip fracture surgical procedures and adverse outcomes, as well fixation time targets that may increasingly compel operations, we investigated the relationship outcomes in a large, population-based cohort. Methods: All Ontarians who were ≥60 years of age underwent procedure April 2002 March 2014 eligible for study inclusion. Data obtained from linked health administrative databases. The primary exposure was...

Background Femoral shaft fractures are common in major trauma. Early definitive fixation, within 24 hours, is feasible most patients and associated with improved outcomes. Nonetheless, variability might exist between trauma centers timeliness of fixation. Such could impact outcomes would therefore represent a target for quality improvement. We evaluated delayed fixation (≥24 hours) participating the American College Surgeons (ACS) Trauma Quality Improvement Program (TQIP) measured resultant...

There is no reliable estimate of costs incurred by motorcycle crashes. Our objective was to calculate the direct all publicly funded medical care provided individuals after crashes compared with automobile crashes.We conducted a population-based, matched cohort study adults in Ontario who presented hospital because or crash from 2007 through 2013. For each case, we identified 1 control absent motor vehicle during period. Direct for case and were estimated 2013 Canadian dollars payer...

Echocardiography is commonly used in hip fracture patients to evaluate perioperative cardiac risk. However, echocardiography that delays surgical repair may be harmful. The objective of this study was compare wait times, mortality, length stay (LOS), and healthcare costs for similar evaluated with without preoperative echocardiograms.A population-based, matched cohort all (aged over 45 years) Ontario, Canada between 2009 2014 conducted. primary exposure (occurring hospital admission...

Patients with a high body-mass index (BMI) are at increased risk for significant complications after total knee arthroplasty (TKA). We explored whether operative time is modifiable factor infectious and thromboembolic complications.A retrospective observational cohort study of the ACS-NSQIP registry, including all patients who underwent primary TKA (2015-2018), were morbidly obese (BMI 40 kg/m2 or greater) was performed. created four categories in minutes: less than 60, 60-90, 91-120,...

Purpose: Total joint arthroplasty (TJA) has seen a rapid increase in same-day surgery (SDS), particularly since the COVID-19 pandemic. One limitation of prior research on this topic is that data derived from single (usually high volume) centers whose experience may not be generalizable. The purpose study was to analyze success rates TJA using population level Canada's most populous province. Methods: Data Ontario's linked, administrative, healthcare databases were obtained for all patients...

<h3>BACKGROUND:</h3> Although a delay of 24 hours for hip fracture repair is associated with medical complications and costs, it unknown how long patients wait surgery fracture. We describe novel methods measuring exact urgent emergent surgical times (in hours) the factors that influence them. <h3>METHODS:</h3> Adults aged 45 years older who underwent (the most common urgently performed procedure) in Ontario, Canada, between 2009 2014 were eligible.
