Abstract:
Reconstructing thumb opposition function using modified transfer of proper extensor tendon of the fifth digit is one of the methods to treat old median nerve injury-induced thumb opposition dysfunction. To explore the long-term effect of this method, 97 patients undergoing modified transfer of proper extensor tendon of the fifth digit to reconstruct thumb opposition function in Department of Hand Surgery, Affiliated Hospital of Beihua University between January 2003 and December 2007 were retrospectively analyzed, and 21 were followed up. The thumb opposition function postoperatively was evaluated using Changing of Hand Function Evaluation Standard. After reconstructing thumb opposition function, length of thumb (T), distance moving to (mo) and moving away from (Mo) centre of palm in opposition, i.e. during closing and leaving centre of palm distance between middle point of thumb interdigit transverse striation and middle point of middle finger MP joint transverse striation. In addition, their ratios were calculated. The patients were followed-up for 7.5 years (ranging 1-14 years). It is a good therapy to reconstruct thumb opposition function using modified transfer of proper extensor tendon of the fifth digit.
