Closed rupture of the deep transverse metacarpal ligament (DTML) is an unusual injury. We have managed 2 patients with closed rupture of the DTML between the ring and small fingers resulting from crush injuries to the hand. Both patients presented with painful ulnar deviation of the small finger with extension. The diagnosis was confirmed by exploration through a volar incision. Repair of the ligament with use of the adjacent A1 pulleys to butress the repair was successful in both patients and restored a painless finger flexion-extension arc. Closed rupture of the DTML can be confused with a metacarpophalangeal joint collateral ligament rupture due to the characteristic deviation of the small finger.
