Biomechanical properties of off-axis screw in the treatment of vertical femoral neck fractures: a finite element analysis

Abstract Purpose This study aims to assess the biomechanical performance of the 7.3 mm fully threaded off-axis screw (7.3-FTOS) configuration in stabilizing vertical femoral neck fractures (FNSs), comparing its effectiveness with other fixation methods. Methods A vertical FNF model with an 80° Pauwe...
