SALT LAKE CITY - Many Winter Olympic sports involve breathtaking, high-flying maneuvers such as freestyle aerial skiing. It was one of these moves, unfortunately, that resulted in a midfoot fracture-dislocation, including a navicular fracture and dislocation between the lateral cuneiform and the cuboid.
The images below were acquired on an Mx8000 quad-detector CT scanner (Philips Medical Systems, Bothell, WA) at the University of Utah hospital, located a few minutes away from the Polyclinic. The images were reformatted on a Marconi PACS station by the radiologist. Reformatting enables the radiologist to choose the optimal plane and angulation.

| Direct coronal CT image through the midfoot, demonstrating dislocation between the lateral cuneiform and the cuboid. Soft-tissue algorithms are routinely used in addition to bone algorithm in CT trauma evaluation to enable evaluation of tendons and ligaments. This soft-tissue image shows tiny avulsion fragments dorsally due to avulsion of the interosseous ligaments between the cuneiform and cuboid. |

| Sagittal reformatted image through the medial aspect of the foot demonstrates the fracture (arrow) of the inferior portion of the navicular. |

![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
