Abstract

Total elbow arthroplasty (TEA) is an effective treatment for multiple elbow pathologies. It is a relatively uncommon procedure relative to arthroplasty of the hip, knee and shoulder; consequently, less literature regarding historical utilization is available. The purpose of this study is to determine the utilization of TEA over the last 15 years for which data is available. This study aims to characterize trends in TEA from 2002 to 2017.The National Inpatient Sample database was queried for all TEA utilization using ICD 9 and ICD 10 codes from 2002 to 2017. A patient demographic analysis for sex, age, and socioeconomic status was conducted. Yearly TEA complication and comorbidity rate was analyzed by dividing the total number of complications/comorbidities each year by the total frequency of TEA each year. Primary diagnosis was categorized as dislocation, fracture, inflammatory arthropathy/rheumatoid arthritis, neoplasm, infection, osteoarthritis, mechanical complication, post-traumatic arthritis and other and analyzed over time.The annual volume of TEA increased from 1713 cases in 2002, to 2753 in 2011. From 2011 to 2013, volume decreased to 1665. A higher proportion of female patients underwent TEA relative to male patients (2.37:1 ratio). The 65-84 age group comprised 33%-47.5% of TEA patients yearly. The number of comorbidities per TEA performed increased consistently from 1.06 in 2002 to 2.40 in 2017 (P < .001). Fracture represented the primary diagnosis associated with TEA in all years with the frequency of fracture-related TEA increasing from 874 in 2002 to 1868 in 2010 (r = 0.87, P = .002), and then decreasing from 1868 in 2010 to 995 in 2017 (r = −0.9, P = .002). The frequency of inflammatory arthropathy-related TEA decreased from 436 in 2003 to 110 in 2017 (r = −0.886, P < 0.001).Several notable trends were identified including a precipitous decline in TEA utilization after 2011. Our data suggests that TEA was performed most commonly for fracture-related elbow pathology every year from 2002 to 2017. Inflammatory arthropathy-related TEA steadily decreased over the study interval yet remained the second most common primary diagnosis associated with TEA. Our data suggests that TEA has been performed most often on women over the age of 65 with an associated increasing comorbidity burden seen during the timeframe of 2002-2017. Identification of these trends is helpful to physicians who must adapt to an evolving TEA patient population.Level IV.
