Abstract：
(1) Introduction: Tendinous mallet finger is a frequent deformity that occurs after an extensor tendon injury during sports or daily life activities. Despite the existence of numerous non-operative and operative techniques to address this deformity, there is a controversy on its optimal management. In this study, we aimed to present a direct tendon suture technique using the distal interphalangeal (DIP) joint open approach for treating tendinous mallet finger injury. (2) Methods: Between 2019 and 2021, 19 patients with closed non-fracture tendinous mallet fingers underwent the direct tendon and paratenon repair technique. After skin incision, we opened the paratenon with lazy S shape incision and found the ruptured proximal and distal tendon ends. We reapproximated the tendons using a simple interrupted suture with Prolene #6/0. After that, we meticulously performed paratenon repair using PDS #6/0 for preventing readherence. Temporary trans-articular Kirschner wire fixation was used for 4 weeks. (3) Results: All patients were followed-up for 3-8 months (mean: 4.8 months). The mean final extension lag was 6.5 degrees, and the overall rate of cases with excellent and good outcomes using Crawford\'s criteria was 85%. (4) Conclusions: In conclusion, this surgical approach could be a reliable alternative for the treatment of tendinous mallet finger injuries.
摘要：
（1）简介：肌腱槌指是在运动或日常生活活动中伸肌腱损伤后发生的一种常见畸形。尽管存在许多非手术和手术技术来解决这种畸形，它的优化管理存在争议。在这项研究中,我们旨在提出一种使用远端指间（DIP）关节开放入路的直接肌腱缝合技术，以治疗肌腱槌状指损伤。（2）方法：2019年至2021年，对19例闭合性非骨折肌腱槌状指患者进行直接肌腱和邻肌修复技术。皮肤切开后，我们用懒惰的S形切口打开腹壁，发现肌腱近端和远端破裂。我们使用Prolene＃6/0的简单间断缝合线重新逼近了肌腱。之后,我们使用PDS#6/0精心进行了Paratenon修复，以防止复发。临时经关节克氏针固定4周。(3)结果:所有患者均获随访3~8个月,平均4.8个月。平均最终延伸滞后为6.5度，根据克劳福德标准，具有优异和良好结局的病例的总比率为85%。（4）结论：总之，这种手术方法可能是治疗肌腱槌状手指损伤的可靠替代方法。
