What Does a Shoulder MRI Cost the Consumer?

Robert W. Westermann MD, Cameron Schick MD, Christopher M. Graves MD, Kyle R. Duchman MD, Stuart L. Weinstein MD

More than 100 MRIs per 1000 inhabitants are performed in the United States annually, more than almost every other country. Little is known regarding the cost of obtaining an MRI and factors associated with differences in cost.

Perioperative Risk Adjustment for Total Shoulder Arthroplasty: Are Simple Clinically Driven Models Sufficient?

David N. Bernstein MA, Aakash Keswani BA, David Ring MD, PhD

There is growing interest in value-based health care in the United States. Statistical analysis of large databases can inform us of the factors associated with and the probability of adverse events and unplanned readmissions that diminish quality and add expense. For example, increased operating time and high blood urea nitrogen (BUN) are associated with adverse events, whereas patients on antihypertensive medications were more likely to have an unplanned readmission. Many surgeons rely on their knowledge and intuition when assessing the risk of a procedure. Comparing clinically driven with statistically derived risk models of total shoulder arthroplasty (TSA) offers insight into potential gaps between common practice and evidence-based medicine.

What Factors are Associated With Clinically Important Improvement After Shoulder Hemiarthroplasty for Cuff Tear Arthropathy?

Jeremy S. Somerson MD, Patrick Sander MD, Kamal Bohsali MD, Ryan Tibbetts MD, Charles A. Rockwood MD, Michael A. Wirth MD

In selected patients with a desire to maintain activity levels greater than those recommended after reverse total shoulder arthroplasty, hemiarthroplasty remains an option for treatment of cuff tear arthropathy (CTA). However, given the relatively small case series that have been reported to date, little is known regarding which patients will show functional improvement after this surgery.

Corticosteroid Injections Give Small and Transient Pain Relief in Rotator Cuff Tendinosis: A Meta-analysis

Amin Mohamadi MD, MPH, Jimmy J. Chan MD, Femke M. A. P. Claessen MD, David Ring MD, PhD, Neal C. Chen MD

The ability of injection of corticosteroids into the subacromial space to relieve pain ascribed to rotator cuff tendinosis is debated. The number of patients who have an injection before one gets relief beyond what a placebo provides is uncertain.

Economic Decision Model Suggests Total Shoulder Arthroplasty is Superior to Hemiarthroplasty in Young Patients with End-stage Shoulder Arthritis

Suneel B. Bhat MD, Mark Lazarus MD, Charles Getz MD, Gerald R. Williams MD, Surena Namdari MD, MSc

Young patients with severe glenohumeral arthritis pose a challenging management problem for shoulder surgeons. Two controversial treatment options are total shoulder arthroplasty (TSA) and hemiarthroplasty. This study aims to characterize costs, as expressed by reimbursements for episodes of acute care, and outcomes associated with each treatment.

What Factors are Predictive of Patient-reported Outcomes? A Prospective Study of 337 Shoulder Arthroplasties

Frederick A. Matsen MD, Stacy M. Russ BA, Phuong T. Vu BA, Jason E. Hsu MD, Robert M. Lucas MD, Bryan A. Comstock MS

Although shoulder arthroplasties generally are effective in improving patients’ comfort and function, the results are variable for reasons that are not well understood.

Is Hepatitis C Infection Associated With a Higher Risk of Complications After Total Shoulder Arthroplasty?

Jourdan M. Cancienne MD, Ian J. Dempsey MD, MBA, Russell E. Holzgrefe MD, Stephen F. Brockmeier MD, Brian C. Werner MD

Despite recent advances in the treatment of hepatitis C, it is estimated that nearly 4 million Americans have a chronic form of the disease. Although research in lower-extremity arthroplasty suggests patients with hepatitis C are at risk for increased complications, including postoperative bleeding, acute postoperative infection, and general medical complications, no similar studies have investigated this question in patients undergoing total shoulder arthroplasty (TSA).

What Change in American Shoulder and Elbow Surgeons Score Represents a Clinically Important Change After Shoulder Arthroplasty?

Brian C. Werner MD, Brenda Chang MS, MPH, Joseph T. Nguyen MPH, David M. Dines MD, Lawrence V. Gulotta MD

The American Shoulder and Elbow Surgeons (ASES) questionnaire was developed to provide a standardized method for evaluating shoulder function. Previous studies have determined the clinical responsiveness of this outcome measure for heterogenous populations or patients with nonoperatively treated rotator cuff disease. Currently, to our knowledge, no studies exist that establish the clinically relevant change in the ASES score after shoulder arthroplasty.

Shoulder Activity Level is Associated With Type of Employment and Income in the Normative Population Without Shoulder Disorders

Robert H. Brophy MD, Kenneth M. Lin BS, S. Andrew Skillington BS, C. Tate Hepper MD, Matthew V. Smith MD

Socioeconomic variables influence various healthcare issues in different ways. The effect of socioeconomic variables on the shoulder has not been well studied. Because activity level, defined by how much a patient actually does, is an important patient outcome measure and prognostic factor for the shoulder, studying its association with occupation and income will advance our understanding of how these variables relate to shoulder disorders, treatments, and outcomes.
