Ulnar Nerve Synovial Impingement

about dynamic ultrasound findings of ulnar nerve synovial impingement

This is the case of a patient suffering for a post-traumatic olecranon bursitis with ulnar nerve entrapment symptoms, one month after an elbow contusion.

A standard plain radiograph was made immediatly after trauma, showing a small bony fragment of the olecranon cortical surface.

Olecranon Bursitis

Sagittal T2w (left) and Axial T2w (right) Mri scans (0.3 Tesla).

The Mri exam shows a gross olecranon bursitis, but the inflammatory process involving the ulnar nerve is better appreciated with the dynamic ultrasound examination.

My suggestion is always tha same… Mri and Ultrasound exams complement each other succesfully, so use both togheter in your daily practice.

Triceps Tendon Avulsion

This injury is considered in literature as the “least common of all tendon injuries”, and for this reason often misdiagnosed; I suggest always to pay attention when you find something calcific after a trauma, especially with ultrasound imaging.

Today I show you the case of complete triceps tendon avulsion occurred after a falling injury that had happened eight days back.

The X-ray examination still assumes great importance in this kind of injury.
