Official Title: Effectiveness and Cost-effectiveness of Conservative and Operative Treatment of Three- and Four-part Fractures of the Proximal Humerus. A Nested Randomised Controlled Trial and Cohort Study
Brief Summary: Fractures of the proximal humerus are common in elderly patients. The optimal treatment of comminuted, displaced fractures is subject to controversy, and the results of operative treatment have not been shown to be superior to conservative treatment. The aim of the study is to compare locking plate osteosynthesis versus treatment with fracture hemiarthroplasty versus conservative treatment in a randomised, controlled protocol. The results of treatment are measured at 6 weeks, 3 months, 6 months, 12 months and 24 months. Main outcome measures are Pain at rest and activity (NRSs) and functional assessment of the shoulder with Constant Score. Secondary outcome measures are Simple Shoulder test (SST), Disabilities of the Arm, Shoulder and Hand (DASH), quality of life assessment (15D), subjective patient satisfaction and costs. The study also has a cohort follow-up of the patiens who decline randomisation.
