Talonavicular joint fixation: a biomechanical comparison of locking compression plates and lag screws.

Background: Fusion of the talonavicular (TN) joint is an effective treatment for hindfoot pain and deformity. Nonunion in hindfoot fusion procedures is most common in the TN joint. The purpose of this study was to evaluate and compare the mechanical stability of 2 different forms of fixation for isolated fusion of the TN joint.
