Abstract:
We retrospectively reviewed a prospectively followed cohort of 105 patients with 110 open tibia fractures treated with external fixator or intramedullary nail to determine whether smoking affects fracture healing. Severe open tibia-shaft fractures treated at a tertiary-care medical center were included. Patients with type II, IIIA, or IIIB tibia fractures were eligible. Treatment for all patients was similar, except that they were randomized to receive external fixator or intramedullary nail. Time to fracture healing was the main outcome measurement. Smokers had a union rate of 84% (52/62), and nonsmokers had a union rate of 94% (45/48), P = .10. For smokers in one arm of the study, time to union was significantly longer (P = .01), and there were more complications (P = .04). Smoking decreased unions, slowed healing, and increased complications.

01:27Fractures: 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...
