Additional bone graft accelerates healing of clavicle non-unions and improves long-term results after 8.9 years: a retrospective study.

Background: Clavicle non-unions can occur after both conservative and operative treatment failure. Here, we investigated the outcome of patients with delayed fracture healing or non-unions of the clavicle. Patients underwent revision surgery by plate osteosynthesis of the clavicle with or without bone grafting.
