Background

Stress fracture of the acromium and scapular spine is a common complication following reverse total shoulder arthroplasty (RSA), with a reported incidence of 3.1%–11%. There is some evidence associating osteoporosis with increased risk of acromial stress fractures, but little else is known about the causes of acromial stress fractures after RSA. This study aims to define better preoperative factors, including demographics, comorbidities, and diagnoses, which predispose patients to postoperative acromial stress fractures.

Methods

We retrospectively identified patients who underwent primary or revision RSA for any indication between January 2013 and December 2018 by two surgeons at two separate hospitals. Stress fractures of the acromion were identified on plain radiographs or computed tomography, when necessary. Patient demographics, comorbidities, and surgical indications were compared between patients with and without acromial stress fractures.

INTRODUCTION

Shoulder arthroplasty (SA) is an effective procedure for managing patients with shoulder pain secondary to degenerative joint disease or end stage arthritis that has failed conservative treatment. Insurance status has been shown to be an indicator of patient morbidity and mortality. The objective of the current study is to evaluate the effect of patient insurance status on outcomes following shoulder replacement surgery.

METHODS

Data was obtained from the Nationwide Inpatient Sample between 2004 and 2011. Analysis included patients undergoing shoulder arthroplasty procedures determined by ICD-9 procedure codes. Patient demographics and comorbidities were analyzed and stratified by insurance type. The primary outcome was medical and surgical complications occurring during the same hospitalization with secondary analysis of mortality. Pearson's chi¬squared test and multivariate regression were performed.
