What this Trial Is About

Clavicle fractures are common and usually heal well without surgery. Most patients recover full shoulder function within a few weeks with conservative treatment, which is the standard in Denmark. However, in cases where the broken ends of the bone do not touch (displaced fractures), there is a higher risk of complications like non-healing (non-union), affecting 11-18% of such cases. Non-union can lead to long-term pain, reduced shoulder function, and a longer recovery time, often requiring multiple follow-up visits. While surgery might prevent these complications for some patients, operating on all displaced fractures would lead to overtreatment. The current challenge is identifying which patients are at risk for non-union and would benefit most from surgery. This study aims to investigate the risk factors for non-union in patients with displaced clavicle fractures by examining both patient characteristics and fracture-related factors. The goal is to use multiple data points to develop a score that can support clinicians and patients in shared decision-making regarding the optimal and individualized treatment for clavicle fractures. This research is important not only for clavicle fractures but also for understanding and treating non-union in other bones like the ulna and tibia, which face similar challenges.
