WebBecause the heat-treated files have a higher resistance to cyclic fatigue as well as an increase in ductility, the incidence of file fracture during clinical use might be reduced (46, 47). ... As rotary NiTi files fracture mainly due to limited fatigue resistance, it can be assumed that success in improving this characteristic of the NiTi files ... WebPosted in Low back, Thoracic. Vertebral compression fractures (VCF’s) are the most common osteoporotic fragility fractures. They have an incidence in the United Kingdom of 120,000 per annum (1). VCF’s are considered a red flag pathology of the spine due to the devastating consequences (albeit rare) they can have upon the patient’s health (2).
