Ways to prevent adverse outcomes and complications of total shoulder arthroplasty

Background Total shoulder arthroplasty (TSA) is a well-established procedure for treatment of severe pathologies of the shoulder joint. However, it is a radical procedure that may result in adverse outcomes and complications. The goal was to identify causes of poor functional outcomes and complications after total shoulder replacement and search ways to prevent them. Material and methods Outcomes of 168 patients were reviewed. Reverse shoulder arthroplasty and cemented humeral fixation was employed for the majority of patients (n = 125; 74.4 %). Minimal follow-up was at least one year with an average term of 3 to 5 years. Clinical, biomechanical examinations, radiography, magnetic resonance imaging, computed tomography, electromyography, DEXA, VAS, ASES, UCLA, statistical analysis were employed in the study. Results Positive results of TSA were observed in 83.3 % of the cases and 16.7 % had poor outcomes. Patients developed implant dislocation in 9.5 %, infection in 3 %, early instability of shoulder component in 1...
