    摘要： A bone fixation system (20, 30) comprises a spacer (22, 32), configured for placement within an intervertebral disc space of a patient between a first vertebral body and a second vertebral body, including a wall (21, 33) having at least one aperture (27, 37) dimensioned for receiving a fastener (26, 36) there through and at least one polymeric element (24, 34) adjacent to the aperture (27, 37). At least one fastener (26, 36) is configured to extend through one of the one or more apertures (27, 37) to secure the spacer (22, 32) to one of the first and second vertebral bodies. A sonotrode (40) is configured change a physical state of the polymeric element (24, 34). Upon introducing the sonotrode (40) to the polymeric element (24, 34), material of the polymeric element (24, 34) flows into a space adjacent the fastener (26, 36) in the aperture (27, 37) such that the material of the polymeric element (24, 34) is in contact with both the wall of the spacer (22, 32) and the fastener (26, 36). Upon removing the sonotrode (40) from the polymeric element (24, 34), the material of the polymeric element (24, 34) is configured to harden to a solid state, thereby preventing the fastener (26, 36) from moving relative to the wall (21, 33) of the spacer (22).
