Advances in Intramedullary Nail Fixation in Foot and Ankle Surgery

Authors: Woods JB, and Burns PR
Abstract: Tibiotalocalcaneal arthrodesis for the treatment of complex foot and ankle deformities are extremely challenging cases. Technological advances in intramedullary nail fixation have improved the biomechanical properties of available fixation constructs in recent years. Nails designed specifically to accommodate hindfoot anatomy, advancement in the understanding of optimal screw orientation, fixed angle technology, the availability of spiral blade screws, and features designed to achieve compression across the arthrodesis site have provided the foot and ankle surgeon with a greater armamentarium for performing tibiotalocalneal arthrodesis. Although advances may help to improve clinical results, small sample sizes and the low-level evidence of study designs limit the evaluation of how these advances affect clinical outcomes.
