Fractures of the cuboid are uncommon. During the last 10 years four patients with cuboid fractures were treated at our hospital. The displaced fractures were treated by open reduction, bone grafting where necessary and internal fixation. At the time of follow-up the results concerning pain and function were good in two patients and excellent in the other two patients. This is superior to the results previously reported for conservative treatment. We recommend open treatment for fractures with displacement of one or more of the articular surfaces or with shortening of the lateral column of the foot.
