Risk Factors for Lateral Trochanteric Pain Following Anterior Approach Total Hip Arthroplasty.

Objectives: The principal aim of our study is to investigate risk factors for lateral trochanteric pain (LTP) after direct anterior approach (DAA) primary total hip arthroplasty (THA).

Methods: A retrospective case control study was developed from 542 patients who underwent primary THA over a 9-year period to form two patient cohorts. Two hundred and seventy-one patients diagnosed with LTP were matched with 271 controls.

Gender disparities among speakers at major spine conferences.

Purpose: To examine ten-year trends in gender representation in speaking roles at major spine conferences.

Background Context: Medical conferences play an important role in career opportunities. There is little analysis on gender representation of major spine conferences despite several studies demonstrating gender disparities within spine surgery.

Does Automated Impaction Improve Femoral Component Sizing and Alignment in Total Hip Arthroplasty?

Background: While automated impaction can provide a more standardized process for femoral canal preparation, little is known regarding its effect on femoral component sizing and position. The purpose of our study was to directly compare femoral component canal fill ratio (CFR) and coronal alignment between primary total hip arthroplasty (THA) procedures performed with automated impaction versus manual mallet impaction.

Methods: A retrospective analysis was performed on 184 patients who underwent primary THA by a single arthroplasty surgeon between 2017 and 2021 with a modern cementless femoral component using either the direct anterior or posterolateral approach.

Incidental findings on CT scans for robot-assisted total joint arthroplasty.

Introduction: This study documented the incidence of incidental findings from preoperative computerized-tomography (CT) scans obtained for robotic-arm-assisted total joint arthroplasty (TJA) and its effect on patient management.

Methods: A retrospective review was conducted for patients who underwent robotic-arm assisted primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) from 2016 to 2020. All patients obtained preoperative CT scans which were formally read by fellowship-trained musculoskeletal radiologists.

Time to Positivity of Cultures Obtained for Periprosthetic Joint Infection.

Background: Despite its well-established limitations, culture remains the gold standard for microbial identification in periprosthetic joint infection (PJI). However, there are no benchmarks for the time to positivity (TTP) on culture for specific microorganisms. This study aimed to determine the TTP for pathogens commonly encountered in PJI.

Should We Aim to Help Patients "Feel Better" or "Feel Good" After Total Hip Arthroplasty? Determining Factors Affecting the Achievement of the Minimal Clinically Important Difference and Patient Acceptable Symptom State.

Background: Recent attempts have been made to use preoperative patient-reported outcome measure (PROM) thresholds as prior authorization criteria based on the assumption that patients who have higher baseline scores are less likely to achieve the minimal clinically important difference (MCID). This study aimed to identify factors affecting the achievement of MCID and patient acceptable symptom state (PASS) after total hip arthroplasty (THA), and to determine the overlap between the two outcomes.

Methods: We identified 3,581 primary, unilateral THAs performed at a single practice in 2015-2019.

Naltrexone alters cardiovascular function following acute forced swimming in mice.

Purpose: Naltrexone (NTX) is an opioid antagonist that can reverse the physiological effects of opioid receptors when bound. Opioid receptors have been found to play a role in cardiovascular (CV) function, and thus, binding of NTX may alter CV activity at rest and in response to acute and chronic exercise (EX). We hypothesized that opioid receptor blockade will alter the typical CV responses following acute EX.
