Ulnar dislocation of the extensor digitorum communis tendon is often observed in multiple rheumatoid arthritis, but trumatic dislocation is relatively rare. We recently encountered 2 patients with traumatic dislocation.Both patients sustained bruise in the dorsum manus. Pain and swelling were observed on the dorsal side of the M. P. joint of the right middle finger. In the M. P. joint of the right middle finger, the extensor tendon was ulnarly dislocated in slight flexion of the finger and reduced with extension. At operation, a hemorrhagic focus was present on the radial side of the extensor tendon of the M. P. joint, and rupture and reversal of the sagittal band were observed.We consider that surgery is more effective than conservative therapy for preventing re-dislocation of the finger extensor tendon. We have obtained good results in fresh cases also by operation in which the extensor tendon in drawn to the radial side using suturing of the sagittal band and juncture tendineum accorrding to Morohashi's technique.
