Open reduction and internal fixation of a radius and ulna fracture in a patient with an elbow arthrodesis: a case report.

This case report outlines the effective use of the Titanium Elastic Nail System (TENS) for treating a peri-implant mid-shaft radius and ulna fracture in a patient with previous elbow arthrodesis and rotational full-thickness flap coverage. Given the paucity of literature surrounding this complex problem, we present a minimally - invasive treatment option which facilitated complete fracture healing, demonstrating the TENS's efficacy in complex orthopedic scenarios.

JUE Insight: The Geography of Travel Behavior in the Early Phase of the COVID-19 Pandemic.

We use U.S. county-level location data derived from smartphones to examine travel behavior and its relationship with COVID-19 cases in the early stages of the outbreak. People traveled less overall and notably avoided areas with relatively larger outbreaks. A doubling of new cases in a county led to a 3 to 4 percent decrease in trips to and from that county. Without this change in travel activity, exposure to out-of-county virus cases could have been twice as high at the end of April 2020. Limiting travel-induced exposure was important because such exposure generated new cases locally. We find a one percent increase in case exposure from travel led to a 0.21 percent increase in new cases added within a county. This suggests the outbreak would have spread faster and to a greater degree had travel activity not dropped accordingly. Our findings imply that the scale and geographic network of travel activity and the travel response of individuals are important for understanding the spread of COVID-19 and for policies that seek to control it.
