A 21-year-old male collegiate basketball player presents with 1 year of left lower leg pain. The pain is worse with activity and the leg is tender to palpation.

Radiograph, bone scan, and CT scans are shown in Figures A-D. What is the next most appropriate step in management?
External beam irradiation with 60Gray to lesion
Neoadjuvant multiagent chemotherapy followed by surgical resection of lesion followed by adjuvant multiagent chemotherapy
Observation and repeat bone scans to plan external beam irradiation of 700cGray to lesion
Indomethacin 25 mg PO tid for 6 weeks
Observation and repeat bone scan followed by surgical resection if no increased uptake
Which test for acute syndesmotic injury of the ankle has the fewest false-positive results and smallest inter-observer variance when used intraoperatively?

A 38-year-old competitive slalom skier is making a turn to the left around a pole. The right ski sticks in the snow as shown in Figure A, causing external rotation of the right ski and boot. Which of the following ankle ligaments is most likely to be the initial structure injured?
