Optical plantar pressure analysis following internal fixation for displaced intra-articular os calcis fractures.

Using optical pedobarography, the outcome of open reduction and internal fixation of displaced os calcis fractures was assessed. In 12 patients, well reconstructed heel contact widths and no reduction in heel-ground contact times were found. In conjunction with this, patients showed lateral deviation of the plantar pressures and load bearing, indicating that subtalar and calcaneocuboid joint function remained altered despite reconstruction. These findings could not be linked to the initial fracture severity or clinical outcome score.
