Do Antibiotic-Loaded Calcium Sulfate Beads Improve Outcomes After Debridement, Antibiotics, and Implant Retention? A Matched Cohort Study.

Background: Dissolvable antibiotic-loaded calcium sulfate beads are used as an intraoperative adjunct during debridement with antibiotics and implant retention (DAIR) for periprosthetic joint infections (PJI) to reduce the historically higher failure rates than one- or two-stage exchange. This study evaluated clinical outcomes after DAIRs performed with and without these antibiotic beads. The primary outcome was post-DAIR failure secondary to recurrent PJI at 2 years.

Soft-Tissue Balancing in Total Hip Arthroplasty.

»: Appropriate total hip arthroplasty (THA) reconstruction must simultaneously address component position, restoration of biomechanics, and soft-tissue balance.

»: Preoperative planning for complex THA cases should include radiographic templating, a detailed case plan that contains backup implant options, and a thorough understanding of the patient's preoperative examination.

»: Using a systematic approach to soft-tissue balancing in THA enhances the ability to intraoperatively execute the preoperative plan.

Preoperative Anemia Independently Predicts Significantly Increased Odds of Short-Term Complications Following Aseptic Revision Hip and Knee Arthroplasty.

Background: Preoperative anemia is an important risk factor for developing complications following revision hip (rTHA) and knee (rTKA) arthroplasty. We aim to determine the effect of anemia severity on 30-day postoperative complications following revision hip and knee arthroplasty.

Methods: A retrospective cohort study was conducted using the American College of Surgeons National Quality Improvement Program Database.

American football is the youth sporting activity most commonly associated with acute vertebral fractures.

Objectives: Athletics confer cardiovascular fitness and improved cognitive processing in pediatric populations. However, one risk of sports participation is acute vertebral fracture, an injury with significant morbidity. It is currently unknown which sports represent the highest risk of acute vertebral fracture in pediatric populations.

Outcomes and Risk Factors of Extended Trochanteric Osteotomy in Aseptic Revision Total Hip Arthroplasty: A Systematic Review.

Background: Although extended trochanteric osteotomy (ETO) is an effective technique for femoral stem removal and for the concomitant management of proximal femoral deformities, complications including persistent pain, trochanteric nonunion, and painful hardware can occur.

Methods: The US National Library of Medicine (PubMed/MEDLINE) and the Cochrane Database of Systematic Reviews were queried for publications utilizing the following keywords: "extended" AND "trochanteric" AND "osteotomy."

Results: Nineteen articles were included in the present study with 1478 ETOs.

Preoperative estimated glomerular filtration rate is a marker for postoperative complications following aseptic revision total hip arthroplasty.

Introduction: Revision total hip arthroplasty (rTHA) is increasingly performed but may carry a high rate of complication. This aim of the study was to determine if a decreased eGFR increases risks of postoperative complications following rTHA.

Methods: A retrospective cohort study using the American College of Surgeons National Quality Improvement Program Database was conducted.

Insulin-dependent diabetes mellitus is an independent risk factor for postoperative complications in aseptic revision total hip arthroplasty.

Introduction: Revision total hip arthroplasty (rTHA) is becoming a more common procedure due to the increasing volume of primary total hip arthroplasty. Diabetes mellitus (DM) is currently projected to affect 4.4% of the global population by 2030.

Increased severity of anaemia is associated with 30-day complications following total joint replacement.

Aims: The aim of this study was to determine the impact of the severity of anaemia on postoperative complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods: A retrospective cohort study was conducted using the American College of Surgeons National Quality Improvement Program (ACS-NSQIP) database. All patients who underwent primary TKA or THA between January 2012 and December 2017 were identified and stratified based upon hematocrit level.

Increased Staphylococcus aureus Nasal Carriage Rates in Rheumatoid Arthritis Patients on Biologic Therapy.

Background: Rheumatoid arthritis patients are at increased risk for periprosthetic joint infection after arthroplasty. The reason is multifactorial. Nasal colonization with Staphylococcus aureus is a modifiable risk factor; carriage rates in RA patients are unknown.

Undisclosed conflicts of interest among biomedical textbook authors.

Background: Textbooks are a formative resource for health care providers during their education and are also an enduring reference for pathophysiology and treatment. Unlike the primary literature and clinical guidelines, biomedical textbook authors do not typically disclose potential financial conflicts of interest (pCoIs). The objective of this study was to evaluate whether the authors of textbooks used in the training of physicians, pharmacists, and dentists had appreciable undisclosed pCoIs in the form of patents or compensation received from pharmaceutical or biotechnology companies.
