Clavicle Fractures: When to Operate and When to Trust the Biology
Clavicle fractures are among the most common injuries in active populations — and among the most debated in terms of operative versus non-operative management. The evidence has matured significantly over the past decade, and the clinical decision framework that emerges from it is more nuanced, more patient-centred, and more evidence-grounded than the broad surgical enthusiasm of the early 2000s.
Midshaft clavicle fractures account for approximately 80% of clavicle injuries and were, for much of the 20th century, managed almost exclusively non-operatively — with excellent results in the majority of cases. The pendulum swung toward surgical fixation in the early 2000s following Canadian cohort studies suggesting higher non-union and symptomatic malunion rates with conservative management than had previously been reported. Surgical fixation rates rose dramatically. Subsequent randomised controlled trial evidence — including the CRAC trial and the Scottish multicentre RCT — has provided a more balanced picture that supports a return to selective surgical decision-making rather than broad operative intervention.
What the evidence supports
The headline finding from multiple RCTs is consistent: primary plate fixation of displaced midshaft clavicle fractures produces faster return to function and lower non-union rates compared to non-operative management, but at 1–2 years the patient-reported outcome differences are small and frequently below the minimum clinically important difference. The group-level evidence does not support universal surgical fixation — it supports informed, individualised decision-making that considers the factors most predictive of poor non-operative outcome.
The risk factors for non-union and symptomatic malunion with non-operative management are well-characterised: complete displacement with no cortical contact, shortening exceeding 2cm, comminution, and patient-specific factors including high occupational or sporting demands on the shoulder girdle. These are the patients in whom surgery is most likely to produce a meaningful improvement over the non-operative alternative. The 20-year-old competitive overhead athlete with a completely displaced, shortened midshaft fracture has a different risk-benefit calculation from the 55-year-old moderately active patient with a similar radiographic appearance.
Complications of plate fixation: the full conversation
Plate fixation of clavicle fractures carries a hardware irritation and removal rate that is not trivial — reported at 20–30% in most series — and which should be communicated explicitly in every consent conversation for this procedure. Wound complications, including hypertrophic scarring over a cosmetically prominent site, are an additional consideration in younger patients for whom the aesthetic consequence of scar formation is significant. The conversation that presents fixation as a straightforward upgrade from non-operative management without acknowledging these specific complications is incomplete.
The clavicle fracture decision that serves the patient best is not the one that follows a rule — it is the one that integrates the fracture characteristics, the patient's demands, their risk profile for non-operative failure, and their informed preference after an honest conversation about both pathways.
💬 Has your threshold for operative fixation of displaced midshaft clavicle fractures changed with the RCT evidence — and how do you currently frame the decision for patients who are asking whether they "need" an operation?
