Dr. Blazuk and colleagues study the Validity of Indirect Ultrasound Findings…

Title: Validy of Indirect Ultrasound Findings in Acute Anterior Cruciate Ligament Ruptures Ken Mautner, MD, Walter I. Sussman, DO, Katie Nanos, MD, Joseph Blazuk, MD, Carmen Brigham, ATC, Emily Sarros, ATC Objectives: Ultrasound (US) is increasingly being used as an extension of the physical examination on the sidelines, in training rooms, and in clinics. Anterior […]

Dr. Lederman and colleagues present a study comparing new techniques for rotator cuff repair!

Title: Triple-Loaded Suture Anchors Versus a Knotless Rip Stop Construct in a Single-Row Rotator Cuff Repair Model Matthew Noyes, MD, Christopher Adams MD, Evan S. Lederman MD, Patrick Denard MD Purpose To compare the biomechanical properties of single-row repair with triple-loaded (TL) anchor repair versus a knotless rip stop (KRS) repair in a rotator cuff repair model. […]

Dr. Evan Lederman and colleagues review how bone reacts to shoulder replacements and propose a classification system for critical review of implant/bone interaction

Title: Stress shielding of the humerus in press-fit anatomic shoulder arthroplasty: review and recommendations for evaluation Patrick Denard MD, Patric Raiss MD, Reuben Gobezie MD, T. Bradley Edwards MD, Evan S. Lederman MD Introduction Uncemented press-fit humeral stems were developed with the goal of decreasing operative time, preserving bone stock, and easing revision. In recent years, […]

Dr. Lederman and colleagues discuss the outcome of a subscapularis peel repair with a stem-based repair after total shoulder arthroplasty

Title: Healing and functional outcome of a subscapularis peel repair with a stem-based repair after total shoulder arthroplasty Reuben Gobezie MD, Patrick Denard MD, Yousef Shishani MD, Anthony Romeo MD, Evan S. Lederman MD Background The purpose of this study was to evaluate functional outcome and healing of a subscapularis peel with a stem-based repair after […]

Dr Lederman, Dr Harmsen and colleagues review strategies to prevent infection in shoulder replacement. *

Title: Preventing infection in shoulder arthroplasty: Navigating the minefields Abstract Periprosthetic infection after shoulder arthroplasty represents a devastating complication that often requires extensive revision surgery with substantial economic and patient burden, and ultimately leads to reduced patient function. Seminars in Arthroplasty Volume 28, Issue 3, September 2017, Pages 145-149 https://doi.org/10.1053/j.sart.2017.12.006 *This is based on a lecture by Dr Lederman at […]

Dr. Lederman, Dr. Lund and former fellows have described a new class of labral tears in the shoulder*

Title: The Glenoid Labral Articular Teardrop Lesion: A Chondrolabral Injury With Distinct Magnetic Resonance Imaging Findings Evan S. Lederman MD, Stephen Flores MD, Christopher Stevens MD, Damien Richardson MD, Pamela Lund MD *Identification of this lesion of MRI can help in diagnosis and treatment of labral tears. Purpose Evaluation and description of a pathognomonic lesion identified on magnetic resonance […]

Dr. Lederman and colleagues discuss the outcome and safety of a short stem shoulder replacement

Title: Short-term clinical outcome of an anatomic short-stem humeral component in total shoulder arthroplasty Anthony A. Romeo MD, Robert J Thorness MD, Shelby A Sumner MPH, Reuben Gobezie MD, Evan S Lederman MD, Patrick J Denard MD Background Short-stem press-fit humeral components have recently been developed in an effort to preserve bone in total shoulder arthroplasty (TSA), but […]

Dr. Lederman and Dr. Harmsen compare different techniques for shoulder replacement*

Title: Glenohumeral osteoarthritis in young patients: Stemless total shoulder arthroplasty trumps resurfacing arthroplasty—Opposes Samuel Harmsen MD and Evan S Lederman MD Abstract When considering shoulder arthroplasty in a younger patient the surgeon can choose between stemmed, stemless or resurfacing implants for humeral reconstruction. Resurfacing arthroplasty can reproduce humeral anatomy independent of the humeral shaft, minimize bone resection and offer potential […]

Dr. Lederman and Dr. Harmsen discuss the challenges and techniques for revision shoulder replacement.*

Title: Humeral cemented revision: Techniques for safe extraction Samuel Harmsen MD, Evan S. Lederman MD Abstract Removing a well-fixed humeral component in revision shoulder arthroplasty can present a difficult challenge. Intraoperative complications including iatrogenic fracture, humeral perforation, segmental bone loss, nerve and soft tissue injury can occur. These complications can occur with both cemented and press-fitted stems and can lead to increased morbidity and decreased functional outcomes. […]

Dr. Lederman and colleagues review how bone reacts to shoulder replacements and document the potential benefit and safety of short stem shoulder implants

Title: Radiographic changes differ between two different short press-fit humeral stem designs in total shoulder arthroplasty Patrick J. Denard MD, Matthew P Noyes MD, J B Walker MD, Youself Shishani MD, Reuben Gobezie MD, Anthony A Romeo MD, Evan S. Lederman MD Background The purpose of this study was to compare the radiographic changes of the humerus in the short […]
