Abstract: Objective To explore the effect of reconstruction on old rupture of finger flexor tendon. Methods There were 30 patients (54 fingers) with old rupture of finger flexor tendon. The silica gel stick was implanted at the first stage. The palmaris longus tendon wrapped in the bioabsorbable membrane replaced the silica gel stick and was implanted at the second stage. The effectiveness was assessed by total active movement (TAM). Results There were 30 fingers as excellent, 20 fingers as good among 54 fingers of 30 patients. The percent of excellent and good was 92.6%. Conclusion Modified reconstruction is effective to prevent from tendon adhesion.

Key words: flexor tendon, chronic injury, tendon adhesion, bioabsorbable membrane
