Reverse total shoulder arthroplasty, which has been performed in Europe for almost 25 years, has shown promising results, especially in patients with specific conditions. This procedure has been indicated mainly for three types of cases: primary osteoarthritis with massive and irreparable rupture of the rotator cuff, severe sequelae of proximal humerus fractures, and revision surgery for a failed arthroplasty. Although reverse arthroplasty has been shown to significantly improve shoulder pain, range of motion, and functionality, it is a complex procedure that can lead to complications, with rates ranging between 19% and 68%. Among the most common complications are neurological damage, instability, periprosthetic fractures and hematoma, with infection being one of the most frequent, especially in revision surgeries, with an incidence that can reach up to 10% in inverted total prostheses. Despite these risks, reverse shoulder arthroplasty remains an effective and reliable option, especially for patients with severe proximal humerus fractures who have failed previous treatments.
