Abstract:

INTRODUCTION The purpose of this study is to analyze national and institutional trends in shoulder arthroplasty utilization by race. METHODS The Nationwide Inpatient Sample (NIS) was analyzed to determine racial trends in shoulder arthroplasty utilization nationally. An institutional database was then utilized to retrospectively identify all patients undergoing shoulder arthroplasty from 2011-2013. Descriptive statistics were utilized to compare self-identified black and non-black subpopulations. RESULTS The NIS identified 256,832 primary shoulder arthroplasties from 2005 to 2011. There were 10,074 (3.92%) cases performed in black patients. Utilization increased from 3.36% in 2005 to 4.49% in 2011. Locally, 1,174 primary shoulder arthroplasties were performed, 70 (5.96%) were black patients. Females accounted for 48/70 (68.6%) of black patients. Black patients had higher BMI (33.6 versus 30.1, p<0.0001) and were younger (62.6 versus 67.2 years, p<0.0001). Regarding insurance type, 1074 (65 black, 1009 non-black) patients had comprehensive insurance data. Chi square analysis of five major insurance categories (private, Medicare, Medicaid, workman’s compensation, and personal injury) found no difference in insurance patterns (χ2= 3.658, p= 0.454). CONCLUSIONS Significant racial disparity in shoulder arthroplasty utilization exists at the national and institutional level. This disparity exists despite similar rates of osteoarthritis in white and black patients. Black patients at our institution had similar clinical, demographic, and socioeconomic patterns as our non-black patients. These results further highlight the need for expanding access of care to black patients in major joint reconstruction.

Impact of Race and Gender on Utilization Rate of Total Shoulder Arthroplasty.

Marked underutilization rates of total joint arthroplasty in minorities compared with nonminorities exist, with a paucity of literature surrounding inequities related to total shoulder arthroplasty (TSA). Using the Statewide Planning and Research Cooperative System database, patients who underwent elective TSA in New York State (NYS) were identified and characterized by age, race, gender, medic...

Failure of Anatomic Total Shoulder Arthroplasty with Revision to Another Anatomic Total Shoulder Arthroplasty

Background: While outcomes of primary anatomic total shoulder arthroplasty (aTSA) are generally favorable, resultsafter revision procedures are less reliable. This study examines the functional outcomes, complications, and implantsurvival in patients who underwent revision of aTSA to aTSA.Methods: Patients who underwent revision aTSA were identified from 2008-2015. Demographic, clinical, surgic...

Shoulder Arthroplasty

Shoulder replacement surgery is done for a variety of reasons. One of the most common indications is the reduction of pain in cases of advanced arthritis. In addition to the goal of pain reduction, most surgeons also try to achieve restoration of shoulder function and increase the patient’s quality of life. Increasingly, these activities are being broadened to not only include activities of dai...

Bilateral anatomic total shoulder arthroplasty versus reverse shoulder arthroplasty.

The results of anatomic total shoulder arthroplasty and reverse shoulder arthroplasty have previously been reported separately. Although the indications differ, scenarios exist in which a patient may have a total shoulder arthroplasty on 1 shoulder and a reverse shoulder arthroplasty on the contralateral shoulder.Between 1992 and 2009, twelve patients underwent bilateral sequential primary shou...

Conversion of total shoulder arthroplasty to reverse shoulder arthroplasty made possible by custom humeral adapter.

Reverse shoulder arthroplasty (RSA) is increasingly being used to revise anatomical total shoulder arthroplasty cases. This procedure's high complication rate has been reduced by the availability of modular shoulder systems, which allows the humeral component to be preserved during the conversion. This case report describes the revision of an anatomical shoulder implant inserted in 1998. Polyet...

Perioperative complications after hemiarthroplasty and total shoulder arthroplasty are equivalent.

BACKGROUND Total shoulder arthroplasty (TSA) results in superior clinical outcomes to hemiarthroplasty (HA); however, TSA is a more technical and invasive procedure. This study retrospectively compares perioperative complications after HA and TSA using the National Surgical Quality Improvement Program (NSQIP) database. METHODS The NSQIP user file was queried for HA and TSA cases from the year...
