| Extensor hood is a structure that stabilizes the extensor tendon at the dorsal side of
the metacarpophalangeal joints and keeps the tendon in place during extension and
flexion of the joint. Diagnosis of Extensor hood injury of a metacarpophalangeal joint is
difficult to diagnose because its clinical symptoms are nonspecific such as pain and
swelling. And swelling can interfere with the accurate physical examination. So the
imaging findings are important for diagnosis of extensor hood injury. Magnetic resonance
image (MRI) and ultrasonography (US) are both good imaging tools. An advantage
of ultrasonography is dynamic assessment of extensor tendon and extensor
hood. Here, we describe a case of US findings of extensor hood injury with dynamic
approach and corresponding MRI findings. |
