Internal Fixation Versus Hemiarthroplasty for Nondisplaced Femoral Neck Fractures: A Systematic Review and Meta-Analysis.

Objective: To compare internal fixation (IF) versus hemiarthroplasty (HA) for elderly individuals (ie, older than 65 years) with nondisplaced (ie, Garden type I or II) femoral neck fracture (FNF).

Data Source: We searched English literature of MEDLINE, PubMed, and Embase from inception to December 4, 2021.

Study Selection: Eligibility criteria were randomized controlled trials (RCTs) compared IF versus HA for elderly individuals with nondisplaced FNF.

Anemia and Its Severity Is Associated With Worse Postoperative Outcomes Following Open Reduction Internal Fixation of Ankle Fractures.

Background: Ankle fractures are often treated in a nonemergent fashion and therefore offer the chance for treatment of preoperative anemia. Although preoperative anemia has been associated with postoperative morbidity following certain types of orthopaedic procedures, its effect on postoperative outcomes following open reduction internal fixation (ORIF) of ankle fractures has not been evaluated. The purpose of this study was to determine the influence of preoperative anemia on 30-day postoperative outcomes following ankle fracture ORIF.

Preoperative Hypoalbuminemia Is Associated With Early Morbidity and Mortality After Revision Total Hip Arthroplasty.

Hypoalbuminemia is associated with early morbidity and mortality in revision total knee arthroplasty. We evaluated the effect of preoperative hypoalbuminemia on 30-day morbidity and mortality in revision total hip arthroplasty (THA). The National Surgical Quality Improvement Program (NSQIP) database was queried from 2015 to 2018 to identify patients who underwent revision THA.

Development and Validation of SCFE Percutaneous Pinning Surgical Simulation.

Background: In situ screw fixation with a single percutaneously placed femoral screw remains widely accepted for femoral head fixation in adolescent patients with slipped capital femoral epiphysis (SCFE). Given the potential risks involved with this procedure, a simulation whereby surgical skills could be refined before entering the operating room may be of benefit to orthopaedic trainees.

Methods: We developed a synthetic model for the simulated treatment of SCFE.

Predictors of USMLE Step 1 Outcomes: Charting Successful Study Habits.

Background: The United States Medical Licensing Examination Step 1 is a test that affects many aspects of medical students' careers. The aim of this study was to assess the predictive value of various studying habits and academic traits.

Activity: A survey concerning Step 1 study habits and scores was collected and analyzed.

Accuracy of Signs and Symptoms for the Diagnosis of Acute Rhinosinusitis and Acute Bacterial Rhinosinusitis.

Purpose: To evaluate the accuracy of signs and symptoms for the diagnosis of acute rhinosinusitis (ARS).

Methods: We searched Medline to identify studies of outpatients with clinically suspected ARS and sufficient data reported to calculate the sensitivity and specificity. Of 1,649 studies initially identified, 17 met our inclusion criteria.

External Validation of Two Classification and Regression Tree Models to Predict the Outcome of Inpatient Cardiopulmonary Resuscitation.

Objective: To prospectively validate a previously developed classification and regression tree (CART) model that predicts the likelihood of a good outcome among patients undergoing inpatient cardiopulmonary resuscitation.

Design: Prospective validation of a clinical decision rule.

Setting: Skåne University Hospital in Malmo, Sweden.

Diagnosis of acute rhinosinusitis in primary care: a systematic review of test accuracy.

Background: Acute rhinosinusitis (ARS) is a common primary care infection, but there have been no recent, comprehensive diagnostic meta-analyses.

Aim: To determine the accuracy of laboratory and imaging studies for the diagnosis of ARS.

Design And Setting: Systematic review of diagnostic tests in outpatient, primary care, and specialty settings.
