Bipartite Hallux Sesamoid Injury

about dynamic ultrasound and MRi findings of post-traumatic injury of a medial bipartite hallux sesamoid bone

Today I show you the injury of a medial bipartite hallux sesamoid bone in a professional football player; extremely painful after trauma, it takes time to heal.

Standard X-Ray exam after trauma.

Sagittal (left) and Coronal (right) Ge-Stir Mri sequences (0.3 Tesla); bone marrow edema of the medial sesamoid is evident.

I always perform also the dynamic evaluation, both with ultrasound and Mri exams.

Plantar Fascitis

About dynamic ultrasound study of chronic plantar fascitis.

In a previous post I wrote about the examination of the plantar aponeurosis;

repetitive traumas produce microtears of some fibers of the plantar aponeurosis, not only close to the site of its attachment but also distally, due to the own foot biomechanics of the patients.

Today I show you the case of a chronic partial rupture of plantar aponeurosis in 20-year-old male soccer player.

As usually I also perform the dynamic ultrasound exam, togheter with elastosonosgraphy evaluation.

The elastosonography examination better depicts the presence of a granulation tissue (green colour) as happened after a partial tear inside the fibrous scar of a chronic plantar fascitis.
