Figure 5 Change in position of the medial sesamoid bone for each operated foot. Anteroposterior X-rays were graded using the Hardy and Clapham scale: (1) Position 1: The entire sesamoid is medial to the first metatarsal bisector; (2) Position 2: The lateral aspect of the sesamoid is tangential to the metatarsal bisector; (3) Position 3: The lateral one-third of the sesamoid overlaps the bisector; (4) Position 4: The sesamoid is centred over the bisector; (5) Position 5: The medial one-third of the sesamoid overlaps the bisector; (6) Position 6: The medial aspect of the sesamoid is tangential to the bisector; and (7) Position 7: The entire sesamoid is lateral to the bisector.
