Fixation devices in rearfoot surgery.

Numerous advances in biomaterials and fixation devices have improved the caliber of rearfoot surgical procedures. An understanding of the underlying physical properties of fixation devices along with the improvement in surgical technique have elevated complex foot surgery to a higher level of quality with improved results. Since the addition and continued improvement of rigid fixation to tarsal arthrodesis, more consistent osseus fusion with a decrease in nonunion has been found.
