The neglected rupture of deep transverse metacarpal ligament.
The deep transverse metacarpal ligament (DTML) extends in radio-ulnar direction between the palmar plates of the metacarpophalangeal (MCP) joints of the second through fifth finger rays. On the radial aspect of the index and the ulnar aspect of the small fingers, the ligament merges with the collateral ligament of the MCP joints. The ligament has palmar grooves for the flexor tendons at the MCP joints and act as a support for the metacarpal arch. Closed DTML injury is an unusual case, but the physical findings of DTML injury are a decrease in grip strength, deviation of the finger in flexion and pain on the affected site of the hand. We have experienced a case of neglected DTML injury of left third interdigital space in a 23-year-old man.
