Multicenter RCT randomizing 200 patients (age 16-60) with acute displaced midshaft clavicular fractures (Edinburgh type 2B) to primary plate fixation or nonoperative management. The study asks whether surgery's apparent functional benefits reflect true superiority or simply nonunion prevention. Outcomes were measured at one year using DASH, Constant scores, 3D CT union assessment, complication rates, and total treatment cost.
The instinct to plate every displaced clavicle is understandable: surgery dramatically cuts nonunion risk and the functional scores look better. But this paper reveals that the score difference evaporates the moment you remove the patients who would have gotten a nonunion anyway.
The practical decision rule: most patients should be counseled toward nonoperative management, because roughly five of every six patients you plate would have healed and done just as well without surgery. Reserve primary fixation for patients with high nonunion risk (smokers, young active males) or those who genuinely cannot tolerate potential nonunion consequences.
The complication trade is also real. Nonoperative patients get nonunion-driven reoperations. Operative patients get plate-removal reoperations. Total reoperation burden is statistically identical at 18-19% — surgery shifts the type of problem, not the overall problem rate.
One nuance worth knowing: 3D CT is the standard for assessing union in clavicular fractures. Radiographic nonunion at 6 months without symptoms may still progress to union by 12 months. Do not reflexively reoperate on an asymptomatic patient with delayed union.
