Objectives/Interrogation: Correction of extensor lag is the key point for treating acute mallet finger in order to avoid swan neck deformity. This study aims to investigate the therapeutic effect of percutaneous advancement of proximal tendon stump with the pull-out technique on treating acute mallet fingers.

Methods: In this prospective study, 22 cases of acute mallet finger received advancement of proximal tendon stump with the pull-out technique. A transverse 3-0 Prolene running beneath the skin was used to advance the tendon distally. The DIP joint was fixed at slight overextension with a 0.8 inch Kirschner wire for 6 weeks. After the removal of the pin, active DIP flexion was started.

Results and Conclusions: The mean extensor lag before surgery was 45° (range 20°-75°). At 6 month follow-up, 15 patients had nearly full range of motion (extension lag<5°), 5 patients had a residual deformity of 10° and two had a poor result with a 30° deformity. 21 patients were fully satisfied with the improvement of DIP extension and only one was unsatisfied, but did not want to receive further treatment. In this preliminary report, this technique using percutaneous advancement of proximal tendon stump with the pull-out technique provided a safe, economic and efficient way of correcting mallet finger deformities without obvious incision during surgery.
