'FEVER' view improves MRI evaluation of the ulnar collateral ligament in throwing athletes
The findings support the FEVER view as practical addition to standard elbow MRI protocols for achieving elbow valgus stress in throwing athletes.
Las Vegas, NV: The flexed elbow valgus external rotation (FEVER) view may improve MRI evaluation of the ulnar collateral ligament (UCL) in throwing athletes, according to results from a pilot study.
According to the results published in the American Journal of Roentgenology, the increased joint space width confirms elbow valgus stress with FEVER view. Diagnostic confidence increased, and additional UCLs were identified as abnormal.
Due to repetitive extreme valgus stress during overhead throwing maneuvers, UCL injuries remain common in throwing athletes. Because standard positioning for elbow MRI is often suboptimal for UCL rendering, Knoblauch, Arizona Diamondbacks head team physician Gary Waslewski, and colleagues piloted their study to assess FEVER view impact on ulnotrochlear (UT) joint space measurement and UCL reader evaluation, as incorporated with conventional elbow MRI.
