Figure 5. Representative case: patient group 1, case 16.

Figure 5A is a radiograph of the left ankle of patient Group 1, case 16, showing a well-corticated, large subfibular ossicle (SO). Figure 5B is a fluid-sensitive MRI sequence showing a high-intensity signal in the gap between the ossicle and the tip of the fibula. Figure 5C shows the ATFL attaching directly to the SO with a gap between the SO and the tip of the fibula. Figure 5D is a postoperative radiograph showing the union of the SO at the time the patient was released to full activity.
