Investigators aim to compare clinical and radiological outcome of use of plate versus screw fixation for calcaneocuboid arthrodesis in adult population.

The calcaneocuboid joint is stable, even although multiple conditions might affect the joint, ranging from osteoarthritis to fracture, subluxation, and dislocation. Calcaneocuboid arthrodesis is more commonly performed as an adjunct procedure with other rearfoot procedures such as triple arthrodesis and is less used as isolated fusion.[1],[2],[3] What the most effective and least cost method for calcaneocuboid arthrodesis?! Many conditions that may affect foot that cause pain ; and there are many methods for relieve that pain , one of these is arthrodesis , and calcaneocuboid joint one of the most affected joints , and commonly we do calcaneocuboid arthrodesis as a part of triple arthrodesis ( subtalar , talonavicular , calcaneocuboid ); The traditional fixation for a calcaneocuboid (CC) arthrodesis in triple arthrodesis is with a 6.5-mm cancellous screw. This procedure can be technically challenging. Fixation with a locking compression plate (LCP) may be easier to perform while achieving compression perpendicular to the fusion site. Investigators suppose that plate is more powerful than screw in calcaneocuboid arthrodesis. The purpose of this study was to compare the load to failure and the stiffness for each fixation method. [4],[5],[6] literature reveal that: More stability to the fusion site can be applied by using plate fixation. Rationale of the research that: calcaneocuboid arthrodesis with screw is effective and least cost compare to plate fixation? [7]
