Abstract
1. Thirteen cases of fracture of the lateral process of the talus seen over a period of thirteen months are reported.
2. The mechanism of the injury would appear to be inversion strain of the foot with dorsiflexion of the ankle.
3. The diagnosis would no doubt be made more often if the possibility of this fracture were kept in mind, and if radiographs of good quality were taken with the ankle at 0 degree and the leg rotated inwards 10 to 20 degrees.
4. With regard to treatment, early operation appears to give good results, a single large fragment being reduced accurately and small or comminuted fragments being removed.
