Biomechanics of fracture fixation
WebBiomechanics. The ideal fracture fixation device would be able to withstand the physiologic loads of postoperative rehabilitation. Typically, to stand in single-leg stance would axially load the femur with 750 N; however, walking or other activities of daily living would generate three to seven times that load. WebMay 1, 2024 · Biomechanics study the role of force and energy in biological systems. The fracture fixation should follow the principle of biomechanics. Excessive stress concentration and fatigue, leading to increased pressure load and bending load, results in internal fixation failure.
