What is the procedure for radiographic evaluations?
Radiographs are required to be taken preoperatively and at postoperative intervals. A Radiographic and Fluoroscopic Manual will be provided to each site that describes the specifications for taking and processing of radiographic images. A Radiographic Evaluation Protocol has been developed which specifies the type and scope of radiographic analysis in this study. A copy of the Radiographic Evaluation Protocol will be provided to each site.
