The use of high-frequency (high-resolution) musculoskeletal ultrasonography is increasing and has shown promising utility in many areas of medicine. The utility of musculoskeletal ultrasonography for foot and ankle complaints has not been widely investigated, however. Although some conditions of the foot and ankle are easily diagnosed by physical examination, others can have nonspecific examination findings, making optimal treatment decisions difficult. ⋯ In 43% of patients, both the diagnosis and the treatment changed after ultrasound scanning. For those patients for whom the diagnosis and treatment were unchanged after the ultrasound examination, the ultrasound findings were concordant with the pre-ultrasound clinical diagnosis for 100% of the patients. These results suggest that in a large proportion of patients, high-resolution musculoskeletal ultrasonography of the foot or ankle can facilitate appropriate diagnosis and management.

Previous studies have described the mechanism of ankle fractures, their seasonal variation, and fracture patterns but never in conjunction. In addition, the cohorts previously studied were either not from trauma centers or were often dominated by low-energy mechanisms. The present study aimed to describe the epidemiology of ankle fractures presenting to an urban level 1 trauma center. ⋯ The ankle fracture patients had greater rates of obesity, diabetes, and smoking than present in the region where the hospital is located. The fractures were most likely to occur in the afternoon, with more fractures presenting on the weekend than earlier in the week and more fractures in the fall and winter than in the spring and summer. The temporal variation of these fractures should be considered for health services planning, in particular, in regard to resident physician staffing at urban level 1 trauma centers.

Although fracture type and treatment options for ankle fractures are well defined, the differences between mono- and polytrauma patients and low- and high-energy trauma have not been addressed. The aim of the present study was to compare the fracture type and trauma mechanism between mono- and polytrauma and low- and high-energy trauma patients with an ankle fracture. We performed a single-center retrospective cohort study. ⋯ The same pattern was observed for ankle fractures after HET compared with LET (p < .001), because all pronation abduction and supination adduction injuries were observed after a HET mechanism. The results of the present study indicate that polytrauma patients sustain different types of ankle fractures than patients with an isolated ankle fracture. This difference likely results from the high-energy transfer associated with polytrauma, because pronation abduction and supination adduction injuries were only observed after HET.
