Device and method for bone imaging |
摘要 |
The invention comprises a modified implant useful to assess bone by imaging. The modified implant comprises a medical implant and at least one detectable marker element associated with the implant that serves as a reference point in medical imaging. Preferably, the implant and the detector marker elements have different radiolucencies such that one element can be seen through the other in medical imaging. |

1. A method of assessing a bone, said method comprising the steps of:
i) implanting into a bone adjacent to a target site, a first bone assessment device comprising (a) an elongate rigid implant for implantation into a bone for assessment of bone fusion and healing, said implant having a first radiolucency detectable with medical imaging, and (b) a marker element associated with the implant, said marker element having a second radiolucency detectable with medical imaging; ii) determining the position of the first bone assessment device by establishing the position of the detectable marker element with medical imaging as a first reference point; iii) applying a load to the bone; iv) determining the position of the first bone assessment device under load bearing conditions by establishing the position of the detectable marker element with medical imaging as a second reference point; and v) determining the distance between the first reference point and the second reference point; wherein a lesser difference in position of the first bone assessment device in the unloaded state as compared to the load-bearing state, is an indicator of bone rigidity. |
