Increasing Use of Reverse Total Shoulder Arthroplasty for Proximal Humerus Fractures in Elderly Patients.
Academic Article
Overview
abstract
This study described surgical treatment patterns for proximal humerus fractures among elderly patients, focusing on reverse total shoulder arthroplasty (TSA), and evaluated how the type of fixation affects inpatient factors (cost, length of stay), transfusion rates, and patient disposition (home vs skilled nursing facility). With Nationwide Inpatient Sample data from 2011 to 2013, the authors identified patients 65 years and older who had proximal humerus fractures and divided them into 3 groups: (1) open reduction and internal fixation (ORIF); (2) hemiarthroplasty; and (3) reverse TSA. From 2011 to 2013, 38,729 surgically treated proximal humerus fractures were identified. The rate of reverse TSA increased 1.8-fold during this time, from 13% of operative cases in 2011 to 24% of operative cases in 2013 (P<.001). At the same time, the rates of hemiarthroplasty and ORIF decreased (hemiarthroplasty, from 28% to 21%; ORIF, from 59% to 55%). Although reverse TSA accounted for 32.2% of arthroplasty procedures for proximal humerus fractures in 2011, this value was 53.3% in 2013 (P<.001). In 2013, mean total hospital cost for reverse TSA was $24,154, which was significantly higher than that for ORIF ($16,269) or hemiarthroplasty ($19,175) (P<.001). In a multivariable model, patients undergoing reverse TSA were less likely than those undergoing hemiarthroplasty to be discharged to a skilled nursing facility (odds ratio, 0.75; P=.027). The national rate of reverse TSA nearly doubled from 2011 to 2013. As of 2013, reverse TSA replaced hemiarthroplasty as the most commonly performed arthroplasty procedure for proximal humerus fractures for patients 65 years and older. Patients undergoing reverse TSA were more likely than those undergoing hemiarthroplasty to be discharged home. [Orthopedics. 2017; 40(6):e982-e989.].
