Shoulder replacement (SR) constitutes the gold standard treatment for severe shoulder diseases, including osteoarthritis, rheumatoid arthritis, complex fractures, avascular necrosis and rotator cuff arthropathy. Further prospective studies on this topic in different countries can be con-ducted to make comparisons. Overall, in Italy, the females represented the majority of patients. The incidence of SR and RSR is expected to increase in the following years, constituting a burden for the healthcare systems. While, an overall cost of 9,855,141€ for RSR procedures in Italy was calculated. From 2009 to 2019, has been assessed an overall cost of 625,638,990€ for TSR or SH procedures in Italy. Overall, females represented the majority of the cases (72.4% of patients who underwent TSR or SH and 59.1% of patients who underwent RSR). While, 2,129 revisions of shoulder replacement were performed, with a cumulative incidence of 0.4 cases per 100,000 residents. Resultsįrom 2009 to 2019, 73,046 TSR and SH were performed in adult Italian residents, with a cumulative incidence of 13.6 cases per 100,000 adult Italian residents. Information about patients was anonymous and included age, sex, days of hospitalization, procedures and diagnoses codes.

The data used in this paper were about patients who underwent Total Shoulder Replacement (TSR), Shoulder Hemiarthroplasty (SH) or Revision of shoulder joint replacement (RSR) from 2009 to 2019 in Italy. Moreover, the economic impact on the healthcare system of SR and SR revisions was assessed, providing a statistical prediction for the next ten years. This paper aims to evaluate the trend of hospitalizations for SR (both first implants and revisions of anatomical and reverse prosthesis) in Italy from 2009 to 2019, based on the National Hospital Discharge Reports (S.D.O) provided by the Italian National Health Service (INHS). Sharing national statistics and correlating those to other countries could be helpful to compare outcomes and costs internationally. Although several countries have national registries, there is a lack of epidemiological data on SR.
