Objective To explore the effect of transosseous tunnel suture combined with Kirschner wire fixation in the treatment of tendinous mallet finger deformity.Methods The clinical data of 31 cases with single tendinous mallet finger treated in our hospital from December 2015 to September 2022 were analyzed retrospectively.The involved finger was thumb in 2 cases,index finger in 4 cases,middle finger in 12 cases,ring finger in 4 cases and little finger in 9 cases,including open injury in 10 cases and close injury in 21 cases,and fresh injury in 15 cases and old injury in 16 cases.The surgery of transosseous tunnel suture combined with Kirschner wire fixation were performed in all 31 cases under finger nerve block anesthesia or brachial plexus block anesthesia.Results Local swelling and pyorrhea was found in one case after the surgery,and healed by dressing change,and primary healing was achieved in other cases in 7 to 15 days after the operation.There was no skin necrosis,infection advancement and non-union.All cases were followed up for 6 to 16 months with an average of one year.No recurrence of mallet finger or nail plate deformity was found.According to Crawford standard,the finger function was excellent in 18 cases,good in 9 cases,fair in 4 cases,and the fineness rate was 87.1％.Conclusion The surgery of transosseous tunnel suture combined with Kirschner wire fixation can reconstruct the tendon insertion,fix firmly,restore finger joint function and movement well,and correct de-formity of tendinous mallet finger effectively,and which is worthy of promotion.
