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 total shoulder arthroplasty (TSA). The hypothesis was that the repair would lead to subscapularis healing in the majority of cases.

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 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.

Title: Proximal Stress is Decreased with a Short Stem Compared to a Traditional Length Stem In Total Shoulder Arthroplasty

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.
