Group 1 displacement of the lateral and medial malleolus fracture was 0.1\u00b10.1 mm and 0.4\u00b10.4 mm, respectively. Group 2 displacement of the lateral, medial, and posterior malleolar fracture was 0.6\u00b10.4 mm, 0.5\u00b10.4 mm, and 0.5\u00b10.6 mm, respectively. Group 3 displacement of the lateral, medial, and posterior malleolar fracture was 0.1\u00b10.1 mm, 0.5\u00b10.7 mm, and 0.5\u00b10.4 mm, respectively. The majority of displacement (64.0% to 92.3%) occurred in the first 50 000 cycles.
