[ 1 ] - Identification of Risk Factors for Abnormal Postoperative Chemistry Labs after Primary Shoulder Arthroplasty

Purpose Purpose The purpose of this study was to determine patient-specific risk factors and clinical intervention rates for abnormal postoperative Chem-7 panels in shoulder arthroplasty patients. Methods Retrospectively, all primary anatomic total (aTSA) and reverse shoulder (RTSA) arthroplasties (between 2007-2013) performed at a single institution were identified. All patients underwent ro...

[ 2 ] - Multimodal Pain Management Protocol Versus Patient Controlled Narcotic Analgesia for Postoperative Pain Control after Shoulder Arthroplasty

  Background: Our institution’s traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. ...

[ 3 ] - Blood Glucose Levels in Diabetic Patients Following Corticosteroid Injections into the Subacromial Space of the Shoulder

Background: Corticosteroid injections are used to treat a variety of orthopedic conditions with the goal of decreasingpain and inflammation. Administration of systemic or local corticosteroids risks temporarily increasing blood glucoselevels, especially diabetic patients. The purpose of this study is to quantify the effects of corticosteroid injections onblood glucose levels in diabetic patient...

[ 4 ] - Early Versus Late Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Does It Matter?

Background: This study compared the outcomes between patients with proximal humerus fractures (PHF) whounderwent acute reverse total shoulder arthroplasty (RSA) to those who underwent an alternative initial treatmentbefore requiring (secondary) RSA.Methods: Patients who underwent RSA after suffering a PHF were identified. Two year clinical follow-up was requiredfor inclusion. Patients were divi...

[ 5 ] - Short-Term Results of the DePuy Global Unite Platform Shoulder System: A Two-Year Outcome Study

Background: The Global Unite Shoulder System is the next generation of implant from the Depuy Global Shoulderline. The primary feature of the Global Unite is adaptability through the interchangeable modular bodies, modular suturecollars, and stems. Short-term functional and radiographic outcomes of the Global Unite Platform Shoulder Systemwere assessed as well as complication and revision rates...

[ 6 ] - Failure of Anatomic Total Shoulder Arthroplasty with Revision to Another Anatomic Total Shoulder Arthroplasty

Background: While outcomes of primary anatomic total shoulder arthroplasty (aTSA) are generally favorable, resultsafter revision procedures are less reliable. This study examines the functional outcomes, complications, and implantsurvival in patients who underwent revision of aTSA to aTSA.Methods: Patients who underwent revision aTSA were identified from 2008-2015. Demographic, clinical, surgic...

[ 7 ] - The Midterm Results of the Delta Xtend Reverse Shoulder System: A Five-Year Outcome Study

Background: The purpose of this study was to examine the mid-term functional outcomes, radiographic results,and revision rates of patients treated with the Delta Xtend Reverse Shoulder System for both primary and revisionarthroplasty indications.Methods: A retrospective review was conducted of records for all individuals who underwent a reverse shoulderarthroplasty using the Delta Xtend Reverse...

[ 8 ] - Acromial Stress Fractures: A Systematic Review

Background: Acromial stress fracture (ASF) is a unique complication of reverse shoulder arthroplasty (RSA) thatcan have substantial influence on clinical results. The purpose of this review is to describe demographics, functionaloutcomes, and union rates for cases of RSA complicated by ASF.Methods: A systematic review was conducted using Preferred Reporting Items for Systemati...

[ 9 ] - Cost Effectiveness of Laminar Flow Systems for Total Shoulder Arthroplasty: Filtering Money from the OR?

Background: Laminar flow ventilation systems were developed to reduce surgical contamination in joint arthroplastyto avoid periprosthetic joint infection (PJI). The goals of this study are to evaluate the cost-effectiveness and economicviability of installing and maintaining a laminar flow system in an operating room.Methods: A Monte Carlo simulation was used to evaluate the c...

[ 10 ] - Revision of Anatomic Total Shoulder Arthroplasty to Hemiarthroplasty: Does it work?

Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...

[ 11 ] - Cutibacterium Acnes is Isolated from Air Swabs: Time to Doubt the Value of Traditional Cultures in Shoulder Surgery?

Background: Given high rates of positive Cutibacterium acnes (C. acnes) cultures in cases of both primary and revisionshoulder surgery, the ramifications of positive C. acnes cultures remain uncertain. Next generation sequencing (NGS)is a molecular tool that sequences the whole bacterial genome and is capable of identifying pathogens and the relativepercent abundance in which ...
