Abstract

The juncturae tendinum (inter-extensor connections) are structures connecting each of the extensor digitorum communis (EDC) tendons. Nine months before the presentation to us, this 21-year-old man had painful swelling on the dorsum of the right hand after punching. At present, the patient showed an ulnar deviation of the long finger and a limited extension of the ring finger. The scarred junctura tendinum between long and ring fingers inhibited proximal sliding of the EDC tendon of ring finger, and affect the functions of adjacent metacarpophalangeal joint. The scarred junctura tendinum was resected, while the sagittal band was preserved to prevent subluxation of the EDC tendon of long finger. One year after operation, the range of motion of fingers was full.
