To evaluate the prognostic factors associated with the clinical outcome, which analysed with use of the Pearson correlation method in AOFAS score and radiographic measurement between normal and the affected site after operative treatment of the calcaneal fractures.

We evaluated 13 patients(13 cases) who had unilateral calcaneal fractures. At the latest follow-up, we calculated the mean differences of the Bohler angle, gissane angle, heel height, calcaneal width, calcaneal length, talocalcaneal angle, talar declination angle, subtalar incongruity between normal and affected site on the lateral view of ankle and tangential view of the calcaneus. And then the correlation between radiographic measurement and the clinical outcome analysed by Pearson correlation method.

Heel height(correlation coefficient = 0.827, p-value<005) and subtalar incongruity(correlation coeffidient = -0.764, p-value<0.05) were closely correlated with the clinical outcome and the B hler angle showed lower correlation coefficiency(correlation coefficiency = 0.470, p-value : 0.104) compare to the heel height.

We suggested that restoration of the heel height and subtalar incongruity was significantly correlated to the clinical outcome after operative treatment of the calcaneal fractures.
