PURPOSE |
To evaluate the clinical value of 3-D-reformations with and without electronic disarticulation of calcaneal fractures compared to axial CT and sagittal reformations. |
MATERIAL AND METHODS |
25 patients with intra-articular calcaneal fractures underwent diagnostic CT-examinations. Axial slices, sagittal and 3-D-reformations with and without electronic disarticulation were performed. The sagittal and both types of 3-D-reformations were compared to the axial slices with regard to the diagnostic criteria: inv... |
RESULTS |
The best proof of involvement of articular facets is found in axial slices and 3-D-reconstructions after disarticulation followed by sagittal reconstructions. Usually on 3-D-reconstructions without disarticulation articular facets cannot be identified because of overlapping bones. The number of fragments is clearly dem... |
CONCLUSION |
The decisive diagnosis for treatment planning is made based on the axial slices supported by sagittal reformations. In unclarified cases 3-D-reformations after electronic disarticulation may provide further information. 3-D-reformations without disarticulation are useless.Motivational Value of Navigation Support Case o... |
