    Published: 13 December 2013

    Abstract (provisional)

    Background

    A new radiographic view was proposed to evaluate the coronal plane alignment of the hindfoot under weightbearing conditions.
    Methods
    We studied 46 feet of individuals with normal appearing asymptomatic feet. On the antero-posterior roentgenogram using this new method, the line from the top of the sustentaculum tali to the lateral-inferior end of the posterior articular surface of the talus was obtained as the standard line showing varus or valgus of the calcaneus. We defined the angle between the longitudinal axis of the tibia and the standard line as described above as Varus-Valgus angle (V-V angle).
    Results

    The mean (+/-SD) V-V angle of the 46 feet studied was 76.4 (+/-3.6) degrees.

    Conclusion

    The findings from this study indicate that it is possible to estimate the alignment of the hindfoot quantitatively by comparing individuals to the mean V-V angle that we calculated in our sample, which was 76.4 degrees.

  2. Too bad these authors failed to acknowledge the radiographic view that I invented from over 25 years ago that produces nearly the same result, but with the foot in a more normal weightbearing position.

  4. Too bad these authors didn't mention another hindfoot alignment radiographic view......of course they wouldn't...it was published in the podiatric medical literature (Kirby KA, Loendorf AJ, Gregorio R: Anterior axial projection of the foot. JAPMA, 78: 159-170, 1988).

    Sometimes I wonder why I spent so much time working on this project to get it completed and then to get it published. Very few people ever reference our paper even though it is one of the first such radiographic views to ever be described. The only older similar view was first described by Cobey twelve years earlier, in 1976 (Cobey JC: Posterior roentgenogram of the foot. Clin Orthop, 118: 202, 1976).
