One fracture of each pair was fixed with two lag screws whereas the contralateral site was stabilised with three lag screws, or two lag screws plus an antiglide screw. The lateral plateau was displaced downwards using a servohydraulic materials testing machine and the resulting force and articular surface gap were recorded. Yield load was defined as the maximum load needed to create a 2.0 mm articular offset at the fracture line. The yield loads of the three-lag-screw (307 ± 240 N) and antiglide constructs (342 ± 249 N) were not significantly different from their two-screw control constructs (231 ± 227 and 289 ± 245 N, respectively). We concluded that adding an antiglide screw or a third lag screw did not provide any biomechanical advantage in stabilising these fractures.FiguresReferencesRelatedDetailsCited ByEx vivo assessment of surgically repaired tibial plateau fracture displacement under axial load using large-volume micro-CTJournal of Biomechanics, Vol. 144Biomechanical superiority of locking plate designed with cluster of head screws compared to conventional buttress plate for fixation of posteromedial tibial plateau fractures: A computational assessment17 February 2022 | Journal of Medical and Biological Engineering, Vol. 23What Is the Critical Tibial Resection Depth During Unicompartmental Knee Arthroplasty?
