Background: The new IOFIX is an intra-osseous fixation device comprising an "X-post" through which a lag screw passes to apparently improve force distribution across an arthrodesis. We conducted a novel human cadaveric study. Our null hypothesis was no difference in force exists in an ankle arthrodesis model stabilized with the IOFIX or a conventional single lag screw. Method: In ten cadaver ankles a pressure transducer was compressed as an IOFIX and standard single lag screws were alternately compared. Results: The median average force created by the IOFIX was 3.95 kg and 2.4 kg for the single conventional lag screw (p <= 0.01). The IOFIX improved contact area across the arthrodesis with a median average of 3.41 cm(2) compared with 2.42 cm(2) in the lag screw group (p <= 0.03). Conclusion: Our results suggest an IOFIX improves force distribution across an ankle arthrodesis compared with a single conventional lag screw. (C) 2014 European Foot and Ankle Society.
