factors may have altered the mechanical properties of bone,
ligament, and tendon. It is also possible that because of the
viscoelastic properties of the articular cartilage and bone,
the load applied for simulation of weight bearing may have
attenuated over the time that specimens were imaged. We
do not know if patients with damage to the bone and soft
tissue of the ankle similar to those created in our model
would be able to withstand weight bearing for the duration
of a CT scan, especially if the talus displaces in the ankle
mortise while standing.

Conclusions
In a cadaveric model of SER ankle fracture, medial clear
space was statistically significantly greater for the experimental condition when assessed by gravity stress radiograph and gravity stress CBCT scan. Under weight-bearing
conditions, the CBCT scanner distinguished between stable
and unstable ankles in the experimental condition and may
be useful for clinical decision making. Future clinical studies are needed to examine this potential.
