Tarsal angles, together with statistical significance, in the two series of clubfeet and in normal feet measured at the CT scan examination

Variable	Torsion angle of ankle	Talar body-neck angle	Calcaneocuboid angle
Congenital clubfeet of the first series (Marino-Zuco technique)	29.9° (22.4°–37.5°)	30.3° (23°–37.6°)	7.7° (–9.1°–24.6°)
Congenital clubfeet of the second series (Ponseti technique)	23.7° (16.2°–31.2°)	22.9° (14.8°–31.8°)	2.5° (–14.9°–19.3°)
Normal feet	21.4° (13.9°–29°)	17.8° (12.3°–23.3°)	13.8° (6.2°–21.5°)
Statistical significance	1st series > 2nd series p = 0.002 1st series > normal feet p = 0.0001 2nd series > normal feet not significant	1st series > 2nd series p = 0.001 1st series > normal feet p = 0.0001 2nd series > normal feet not significant	2nd series < normal feet p = 0.001 1st series < normal feet not significant 1st series > 2nd series not significant
