Purpose:
The purpose of this study was to evaluate the impact of tobacco abuse in the consolidation of fractures.
Methods:
We retrospectively identified all patients with a diaphyseal fracture (femur, tibia, or humerus), between January 1999 and December 2010, in our orthopaedic trauma registry (Erasme hospital, Brussels, Belgium). Thirty-eight diaphyseal nonunions (ten femurs, 16 tibias and 12 humerus) were identified. Each nonunion was paired (on age, sex and location) with two control-healed fractures (76 control patients). The chi-squared test and a binary logistic regression were used for statistical analysis.
Results:
In multivariate analysis, smoking (tobacco use) was significantly associated with nonunion, whether the fracture was open or closed (p < 0.01). In univariate analysis, open fracture was associated with a higher risk of nonunion (p < 0.05), while external fixation was associated with better bone healing (p < 0.05).
Conclusion:
Tobacco is confirmed as a deleterious factor for diaphyseal bone healing.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
