among subjects were several magnitudes larger than intraindividual variations (Fig. 3).

DISCUSSION
Clinical evidence suggests that anatomic fracture reduction is very important, especially
at the joint surface. Articular incongruities can induce the early ageing of joints.
Currently the degree of reconstruction is rarely compared to the healthy side and
anatomical differences between patients are not taken into account [7]. All of the
radiographic outcome measurements are actually based on a 2D view. The majority of
previous studies have shown that 2D parameters are not sufficient to determine the
quality of anatomical reconstruction after surgical treatment and the functional outcome
[7], [10–13]. The results show that only small intraindividual differences within the
anatomy exist. CT image data from the contralateral (non fractured) side, could
therefore guide surgical restoration and could also be used to evaluate the quality of
joint. The computational tool presented in this study may be used to evaluate outcome
and quality of operative treatment of joint reconstructions in the hind foot.
