Two-Stage Flexor Pollicis Longus Tendon Reconstruction Using Pedicled Palmaris Longus Tendon Graft

Background. Free tendon grafts are frequently used in zone 2 flexor pollicis longus tendon reconstructions. However, pedicled tendon grafts have less risk of adhesion than free tendon grafts. The aim of this study was to evaluate the results of two-stage flexor pollicis longus tendon reconstruction using a pedicled palmaris longus tendon graft. Methods. Six patients who underwent two-stage flexor pollicis longus tendon reconstruction using a pedicled palmaris longus tendon graft between 2016 and 2018 were retrospectively evaluated in this study. The mean follow-up was 17 months (range: 13-25 months). Results. In the final follow-ups, the Buck-Gramcko score was excellent in three patients, good in two patients, and fair in one patient. Mean Disabilities of the Arm, Shoulder and Hand score was 12.9 (8.3-26.7). Conclusions. We conclude that good results can be achieved with two-stage flexor pollicis longus tendon reconstruction using a pedicled palmaris longus tendon graft. This method appears to be an alternative for flexor pollicis longus tendon reconstruction using free tendon graft.
