Evaluation of tautening method in repair of advanced mallet finger without bone fracture

Abstract

Many different repair methods have been described in the frequently seen mallet finger deformity, but without consensus. The present study aimed to present an alternative tautening technique in mallet finger repair and to compare it versus classical direct repair. Patients with untreated chronic mallet finger of more than three months’ progression, treated surgically between March 2017 and October 2020, were included. Two surgical methods were applied to restore extensor function of the distal interphalangeal joints. In the first group, the granulation tissue was excised and the extensor tendon was repaired directly. In the second group, granulation tissue was not excised, and the extensor tendon was tautened by plication. Outcomes were evaluated according to Miller’s criteria. Fort-six patients were included: group 1, 25 patients; group 2, 21 patients. Mean age in group 1 was 36.2 years and 33.4 years in group 2. Mean follow-up in group 1 was 14.8 months and 13.9 in group 2. Extensor lag was similar (5.6°) in both groups at the end of the sixth month. On Miller’s mallet finger criteria, group 1 scored 3.4 points and group 2 3.4 points (p > 0.05). The tendon tautening method helps to start physiotherapy early, the learning curve is short, and it provides functionally positive results and a low complications rate. We think that this method should be evaluated in chronic mallet finger deformities without bone fracture.
