Dr. Parsons Contributes To Medical Textbook On Reverse Shoulder Arthroplasty

Mar 24, 2021

Dr. Parsons expertise in reverse shoulder arthroplasty was featured in a recently published medical textbook with internationally renowned faculty. 


First FDA approved for clinical use in the United States in 2004, reverse shoulder replacement now accounts for roughly 70% of all shoulder replacements and can be used for an increasing array of indications including advanced arthritis, irreparable rotator cuff tears, failed prior surgery, and fractures. The technology and techniques related to this procedure have undergone tremendous advancement in the past 10 years spurred by significant growth in demand and a better understanding of factors contributing to success and failure. 

Dr. Moby Parsons, a fellowship-trained shoulder surgeon practicing in Portsmouth, NH was the first surgeon in New Hampshire to implant a reverse shoulder replacement and has been a been intimately involved in implant design, clinical research and the development of preoperative planning software and surgical navigation systems currently used worldwide in reverse shoulders. 

This experience led to his invitation to contribute to a textbook entitled “Reverse Shoulder Arthroplasty – A Comprehensive, Case-Based Approach.” This book brings together an international panel of shoulder experts addressing all aspects of the procedure. Parsons’ contribution focused on physical examination and appropriate imaging studies for a variety of clinical scenarios where reverse shoulder can be used. Parsons drew 10 cases from his own clinical practice to demonstrate the most important aspects pertinent to each diagnosis that surgeons must understand when assessing different shoulder conditions for reverse replacement. This book represents the most up-to-date compilation of information on this important tool in the clinical armamentarium of shoulder surgeons.

Dr. Parsons’ clinical research in shoulder replacement has also contributed to the recent introduction of a machine-learning tool to predict clinical outcomes after anatomic and reverse shoulder replacement. Called Predict+ this clinical decision support tool can be used by surgeons to help patients understand their expected outcome after surgery based on clinical evidence from thousands of patients who have previously undergone this procedure. This information can be matched to the patients by age, gender and diagnosis to provide an accurate prediction of outcomes over time and potential complication rates. Parsons has also contributed to 6 clinical research articles on shoulder replacement that have been published in peer-reviewed medical journals in the past 2 years.

Dr. Parsons practices at the The Knee, Hip and Shoulder Center in Portsmouth, NH and is a joint replacement specialist with a focus on outpatient surgery and rapid recovery.
