Are hard-copy prints from peroperative fluoroscopy images useful as documentation?

We have examined the applicability of peroperative image documentation, in promoting early mobilization after osteosynthesis and saving the standard X-ray examination. One hundred and twenty-three patients with proximal femoral fractures were included in the investigation. Hard-copy reprints were recorded from peroperative fluoroscopy images by Fuji Film Thermal Imaging System FTI 200. These reprints were compared with the standard X-rays to assess the quality of the osteosynthesis and possible restriction in mobilization. The specificity of finding an unstable osteosynthesis was 0.40, whereas the sensitivity of finding a stable osteosynthesis was 0.96. In all, four unstable osteosyntheses were overlooked on the hard copy reprints. The specificity of finding patients in need of restricted mobilization was 0.44 and the sensitivity of finding patients allowed free mobilization was 0.93. Eight patients needing restricted mobilization were overlooked on the reprints. Hard-copy images do not safely reveal unstable osteosynthesis and cannot replace the standard X-rays taken postoperatively.
