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.

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 few studies have reported outcomes of these devices. The purpose of this study was to evaluate the short-term clinical outcomes of an anatomic short-stem humeral component in TSA. We hypothesized that the implant would lead to significant functional improvement with low rates of radiographic loosening.

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 easier revision surgery. The resurfacing implant has been in use for over 30 years and has favorable long-term outcome.

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. Complete removal of the cement mantle and cement restrictor, when necessary, can present even further challenges. Several extraction techniques have been described that can help minimize complications and enable safe, complete component extraction.

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 term after total shoulder arthroplasty with two different short-stem humeral components. The hypothesis was that there would be no difference in radiographic changes or functional outcome based on component type.

Patrick J. Denard MD, Matthew P Noyes MD, J B Walker, MD, Yousef Shishani, MD, Reuben Gobezie MD, Anthony A Romeo, MD, Evan S. Lederman, MD

Background

This study compared the outcome and radiographic humeral adaptations after placement of a traditional-length (TL) or short-stem (SS) humeral component during total shoulder arthroplasty (TSA). The hypothesis was there would be no difference in outcome or radiographic adaptations.

Dr Lederman, Dr Hosack and colleagues from the University of Arizona College of Medicine Phoenix discuss the potential for Vancomycin Powder to prevent infection in shoulder replacement.

Title: In vitro susceptibility of Propionibacterium acnes to simulated intrawound vancomycin concentrations

Luke Hosack MD MS, Derek Overstreet PhD, Evan S Lederman, MD

Background

There is convincing evidence supporting the prophylactic use of intrawound vancomycin powder in spinal fusion surgery and mounting evidence in the arthroplasty literature suggesting that it can reduce surgical site infections. As a result, a number of shoulder arthroplasty surgeons have adopted this practice, despite a paucity of evidence and the presence of a pathogen that is, for the most part, unique to this area of the body—Propionibacterium acnes. The purpose of this study was to evaluate the efficacy of vancomycin against planktonic P. acnes in vitro, using time-dependent concentrations one would expect in vivo after intra-articular application.
