Objectives: Rupture of the ulnar collateral ligament (UCL) is a frequent injury of the hand. When untreated, this injury may lead to decreased pinch strength, pain, instability, and osteoarthritis.

There was clinical observation of the long term (over 1 year) effect on the ptotic palpebral-malar sulcus and lower eyelid retraction. RESULTS The patients were followed up for 12–24 months (mean 16).
