Results of accuracy testing of tibial torsion angle measurements in the torsional deformity model of the canine tibia.
| Comparison between anatomical (goniometer) and CT-based (software) tibial torsion angle measurements in a canine tibial torsional deformity model in 13 preset diaphyseal torsion angles | ||
|---|---|---|
| Preset diaphyseal torsion angles (n = 13) Antetorsion positive (+) and retrotorsion negative (−) | Tibial torsion angle measurements | |
| Bone: macroscopically manually goniometer measured tibial torsion angle | CT-Scan: digitally (software) based angular measurement of the tibial torsion angle | |
