Normal MR imaging findings of the midhand and fingers with anatomic correlation.
In the present article, we correlate MR imaging studies of cadavers, volunteers and patients with cadaveric dissection and sectioning. First anatomy at wrist level is discussed. In a next section, we address the midhand with the flexor and extensor tendons, and interosseous and lumbricalis muscles. The dorsal hood at the level of the metacarpophalangeal joint is also addressed. An overview of the anatomy of the thenar is provided. Finally, the flexor system of the fingers with pulleys and volar plates, as well as the central and distal insertion of the finger extensor tendons is discussed.
