Answer

Murray et al reported that smoking was the greatest risk factor for nonunion among patients treated nonoperatively for diaphysial clavicle fractures. In a study, the investigators followed the healing course of 941 patients with such fractures and, using multivariate analysis, found that, along with smoking, both comminution and fracture displacement were particularly significant factors in nonunion.
