A transverse sonogram of the third metacarpophalangeal joint when the finger is extended shows an abnormal radial sagittal band with irregularity and hypoechogenicity (arrow). The extensor tendon (asterisk) is positioned normally. B. A dynamic examination obtained in the transverse plane during finger flexion shows dislocation of the extensor tendon (asterisk).[1]
