Fatigue Strength of Medial Column Plates
نویسندگان
چکیده
Introduction: The use of plate systems represents a well-recognized technique for obtaining an effective compression, reduction and stabilization of the medial column of the foot. In this study, the in vitro fatigue strength of NCM (Medial Column Fusion) plates was determined and compared to a competitor’s equivalent foot system. Material: Two plates were investigated: Stryker VariAx 2 NCM Plate and Wright Medical Darco RPS Plate. Method: The fatigue strength of the plates was evaluated by dynamic loading in a four-point bending setup. Results: The Stryker NCM Plate showed + 121.3% higher strength compared to the Wright Medical plate (p=0.001) Conclusion: This biomechanical study provides valuable data on the in vitro fatigue strength of NCM plates. The Stryker VariAx 2 NCM Plate showed superior fatigue strength with respect to a competitor product tested under the same conditions and used in the same anatomical region.

متن کاملRedesign of Indonesian-made osteosynthesis plates to enhance their mechanical behavior.
Mechanical properties determined by fatigue strength, ductility, and toughness are important measures for osteosynthesis plates in order to tolerate some load-bearing situations caused by muscle contractions and weight-bearing effects. Previous study indicated that Indonesian-made plates showed lower mechanical strength compared to the European AO standard plate. High stress under load-bearing ...
