Simple fracture – maintain navicular concavity
When treating fractures of the navicular, it is important to maintain the concavity of the navicular.
In simple fractures, reduction compression devices may lead to overcompression and loss of shape and congruency. This affects talonavicular (TN) joint motion, if the tips of the reduction clamp are positioned to far proximally, a malreduction is usually the result. The tips should be positioned in such a way as to provide even compression across the fracture.
