  Objective:The objective of this study was to test a newly developed implant for the treatment of intertrochanteric fractures, the X-Bolt, against the current gold standard, the Dynamic Hip Screw (DHS), by comparing the amount of energy required to cause failure of both of them. Methods:Push out studies were performed with both the dynamic hip screw and the X-Bolt in an artificial bone substrate in the form of polyurethane foam blocks, which have predefined mechanical properties. These push out studies were performed as a means to investigate each implants resistance to ‘cut out’ as this is the most common mode of failure with the DHS. Results: The results demonstrate that the X-Bolt produced a force displacement curve with a different pattern of failure than the DHS. The X-Bolt initially required less energ.. Read More»
