Do clinical results of arthroscopic subtalar arthrodesis correlate with CT fusion ratio?

Background: CT analysis of arthroscopic subtalar arthrodesis rarely finds complete fusion. The aim of the present study was to determine, at 12 months' follow-up of arthroscopic subtalar arthrodesis: (1) CT fusion ratio, (2) functional results, and (3) the correlation between the two.

Hypothesis: Incomplete fusion ratio does not impair the result of arthrodesis.
