Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="rcs1614-sec-0001" sec-type="section"> <title>Background</title> <p>Surgical complications such as healing problems, in fractures treated using the Arbeitsgemeinschaft für Osteosynthesefragen (AO) technique, present functional and economic challenges to patients and treatment dilemmas for surgeons. Computer‐assisted orthopaedic surgery using minimally invasive techniques focused on biological osteosynthesis is a novel direction for fracture treatment.</p> </sec> <sec id="rcs1614-sec-0002" sec-type="section"> <title>Method</title> <p>We modified the hexapod computer‐assisted fracture reduction system by introducing a new reduction strategy, building a new system configuration and upgrading the corresponding software. We then validated the entire system, using a fracture model of bovine femur.</p> </sec> <sec id="rcs1614-sec-0003" sec-type="section"> <title>Results</title> <p>Precision tests were performed seven times on a bovine femur with a transverse fracture. Residual deviation was 1.23 ± 0.60 mm in axial deflection, 1.04 ± 0.47 mm in translation, 2.34 ± 1.79° in angulation and 2.83 ± 0.96° in rotation.</p> </sec> <sec id="rcs1614-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Our new reduction system described here is detachable, flexible and more precise in coordinate transformations. The detachable, modular design will allow for more analogous applications in the future. Copyright © 2014 John Wiley & Sons, Ltd.</p> </sec> </abstract>
