Comparison of Palmaris Longus Tendon Graft and Extensor Indicis Proprius Tendon Transfer for Reconstruction of the Extensor Pollicis Longus Tendon

摘要

Purpose To compare the results of reconstruction of extensor pollicis longus tendon treated by palmaris longus tendon graft and extensor indicis proprius tendon transfer. Methods Authors have performed reconstruction of the delayed 27 cases of the ruptured extensor pollicis longus tendon from March 2006 through February 2016 at Jeju National University Hospital with either palmaris longus tendon graft or extensor indicis proprius tendon transfer. Out of 27 patients, 12 patients were treated by palmaris longus tendon graft and 15 patients were treated by extensor indicis proprius tendon transfer. Postoperatively thumbs were immobilized with thumb spica short arm splint in extension and abduction position for 4 weeks. Active and passive exercise of the thumb with extension and abduction was recommended. The functions of the thumbs were assessed by the Riddell's classification and statistically compared. Results At average 21.7 months follow-up, 13 cases (48.1) were excellent, 11 cases (40.7) were good, and 3 cases (11.1) were fair according to the functional evaluation of Riddell. No significant differences were noted between two groups except the operation time. Conclusion Ruptured extensor pollicis longus tendon could be reconstructed with palmaris longus tendon graft or extensor indicis proprius tendon transfer and final functional outcome could be good in long-term follow-up.
