THE STENER LESION REVISITED - A CASE-REPORT

Proximal displacement of a ruptured ulnar collateral ligament of the m etacarpophalangeal joint of a thumb (Stener lesion) can result in chro nic instability if left untreated. Rupture without displacement genera lly leads to complete recovery. An associated fracture can give inform ation about the position of the ruptured ligament. However, 2 cases ar e presented demonstrating that displacement of the ligament can occur in the absence of displacement of the bony fragment. This suggests:hat physical examination is required to determine stability with injuries to the ulnar structures of the thumb metacarpophalangeal joint.
