About Mri and Ultrasound study of palmar fibromatosis of the hand.

This fibrosing hand disorder often leads to progressive and debilitating flexion contractures of the fingers. The diagnosis is made clinically but defining how much a fibrous nodule infiltrates a tendon is a keyelement in the diagnosis and treatment strategy, especially because recurrence after surgery is common.
For this reason I always perform both Mri and ultrasound examinations in my daily practice. Always.

The video below demonstrates the nodule traction on the underlying flexor tendons, resulting in flexion contractures of the digits (Dupuytren contractures).
