Computational comparison of different plating strategies in medial open-wedge high tibial osteotomy with lateral hinge fractures
Journal of Orthopaedic Surgery and Research Sep 18, 2020
Chen YN, Chuang CH, Yang TH, et al. - Researchers applied computer simulation to correlate mechanical stabilities in high tibial osteotomy (HTO) for different lateral hinge fractures (LHFs) fixed with medial and bilateral locking plates. They constructed a finite element knee model with HTO and three types of LHF, namely T1, T2, and T3 fractures, based on the Takeuchi classification. They further applied either medial plating or bilateral plating to fix the HTO with LHFs. The data exhibited that in LHFs, bilateral plating is a recommended strategy to restore HTO stability. Moreover, the stress on the medial plate for lowering plate breakage risk can be reduced by using a D-hole locking screw.
