The Scandinavian Displaced Lateral Clavicle Trial

The Scandinavian Displaced Lateral Clavicle Trial (ScanDiLaC) - A Multicentre, Pragmatic, 12-Month, Non-inferiority, Randomized Controlled Trial

A multicentre multinational RCT to investigate whether non-surgical treatment is non-inferior to surgical treatment for displaced extraarticular lateral clavicle fractures in adults.

The aim of this study is to investigate whether non-surgical treatment is non inferior to surgical treatment for displaced lateral clavicle fractures with regards to functional outcome measured with different patient-reported outcome measures. Patients aged 18-65 years will be randomized to non-surgical or surgical (pragmatic) treatment. The primary outcome is the Disabilities of Arm Hand and Shoulder (DASH) score at 1 year.

• Open fracture
