Intraoperative Myelography in Cervical Multilevel Stenosis Using 3D Rotational Fluoroscopy: Assessment of Feasibility and Image Quality

Figure 4

Intraoperative myelogram obtained for the purpose of decompression control. Vertebral bodies were distracted with Caspar-pins ((a) and (b)) which caused a considerable artifact making the assessment of sufficient decompression difficult. After removal of the Caspar-pins and implantation of intervertebral cages at the disc levels C5/6 and C6/7 and instrumentation with a plate screw osteosynthesis ((c) and (d)), the assessment of the extent of decompression is better with reduced metal artifacts.
