Complications Following Ulnar Artery Catheterization for Coronary Angiography.

Background: Use of radial and ulnar access has increased due to its perceived benefits over femoral access. Ulnar artery catheterization can place patients at risk of significant complications, including pseudoaneurysm, expanding hematoma, compartment syndrome, ulnar nerve injury, and critical hand ischemia. The purpose of this study was to describe complications specific to ulnar artery catheterization.

The Sigmoid Notch View for Distal Radius Fractures.

Purpose: This study defines the sigmoid notch view of the distal radius. Specifically, we tested the null hypothesis that there is no relationship between the subchondral stripe of bone seen on a sigmoid notch view of the distal radius and the articular surface of the sigmoid notch.

Methods: We used 44 wrist specimens for anatomic and fluoroscopic analysis.
