Multiple case reports of fifth metatarsal (MT) intramedullary fixation highlight symptomatic hardware with screw head impingement on the cuboid. We developed a fifth MT intramedullary screw trajectory model using weightbearing computed tomography data. The goal was to assess for cuboid impingement with simulated intramedullary screw position.

In conclusion, the ideal guidewire placement for fifth MT intramedullary fixation is directly against the cuboid. Approximately 95% of patients would have cuboid impingement if the screw is not countersunk. The oblique fluoroscopic view of the foot is a reliable assessment of screw head impingement on the cuboid.
