Figure 2.

Flat talus in the foot with a short calcaneal tuber, despite a restored Bohler angle. Postoperative and contralateral weight-bearing lateral ankle radiographs of a patient with a restored Bohler angle (BA 39° vs. 40°), but with a short tuber (TL difference >4.0 mm). This has caused the ankle to hyper-dorsiflex for the foot to achieve a plantigrade stance, flattening the talus compared with the contralateral limb (TDA 15° vs. 27°). Bonesetter App measurements listed: Tuber length (TL-red) with a best-fit circle around the talar dome. Bohler angle (BA-blue), calcaneal height (CH-green), and talar declination angle (TDA-yellow) are also shown.
