Radiograph taken with the faxitron machine: The technique, where the entire bone or bone samples already cut in blocks are radiographed with the faxitron machine, allows the assessment of bony changes, such as bone resorption (arrow head) or bone sclerosis (arrow) as a means for biocompatibility of the inserted biomaterials. In Fig. 9a an entire femur is shown (arrow: Bone-fixation device), whereas in Fig.9b only the original defect with a rim of adjacent bone is pictured.
