.0002) were significant in the univariate analysis. The mean
FAO was respectively -1.40 (SD: 5.50) and 3.56 (SD: 5.31)
with and without a history of CAI. No significant difference
of age or BMI was shown. After verification of log-linearity
between odds of CAI and FAO, the multivariate logistic
regression adjusted for gender demonstrated a 15% increase
of odds of CAI per unit increase of varus (adjusted Odds Ratio
(CI95%): 0.858 (0.771-0.943) p=0.003), and no more significant effect of gender after adjustment on FAO (Odds ratio
(CI95%) Female versus Male: 0.548 (0.185-1.669) p=0.277).
Conclusion: A positive linear relationship was found between
Varus Hindfoot Alignment measured using a semi-automatic
tool in WBCT and the odds ratio for Chronic Ankle Instability,
thus confirming and quantifying previous findings. The recent
development of semi-automatic measurements and prospective databases opens future perspectives for big data and multivariate analysis in foot and ankle pathology.

Introduction/Purpose: Varus hindfoot deformity may
increase the risk of chronic ankle instability (CAI).
Weightbearing CT (WBCT) semi-automated measurements
and built-in databases may contribute to investigate the relationship between clinical and radiographic data. The objective of this study was to analyze hindfoot alignment (HA) in
relation with CAI in a series of patients using these new tools.
We hypothesized that there would be a positive correlation
between a varus morphotype and a history of CAI.
Methods: This is a Level 3 retrospective comparative study
of a continuous series of 124 feet (63 patients) referred from
July to December 2016. and subsequently assessed by WBCT
(PedCAT®, CurveBeam LLC). The measurement software
(Talas ®,Curvebeam LLC), gave HA as a value of Foot and
Ankle Offset (FAO). This measures the offset between the
center of the ankle joint and the median line of the foot joining the centers of the calcaneus and forefoot weight bearing
surfaces. Data was prospectively saved in a database
(CubeView®, CurveBeam, PA, USA). The definition of CAI
was a history of at least 3 ankle sprains during a 6 months
period. Exclusion criteria were medial instability and syndesmotic injuries (2 cases).A univariate analysis was conducted
to study CAI against the following variables: gender (Fisher),
BMI and FAO (Kurskal-Wallis). The significant variables
were subsequently included in a multivariate logistic model.
Results: Nineteen feet had CAI, in 12 patients. Gender
(p=0.0467 -the proportion of women for patients with CAI
was 72.3%, compared to 33.3% without CAI) and FAO (p=0
