Avulsion fracture types II and III of flexor digitorum profundus (FPD), also called Jersey Finger, in flexor zone 1 are an uncommon pathology requiring surgical treatment. The aim of this study was to assess whether hook miniplates were an accessible and reliable option to repair FDP avulsion types II and III. Between July and August 2018, we treated 2 consecutive patients' zone 1 Leddy-Packer type II and III FDP injuries with hook plates and 1.2 × 7 mm screws included in Medartis Aptus Hand fixation system set. Patients were aged 37 and 39 years, a man and a woman, respectively. At the end of the follow-up, we evaluated the Visual Analog Scale, range of motion, grip strength, and Quick Disabilities of the Arm, Shoulder, and Hand. Both patients completed 12 months of follow-up with excellent functional and radiological results. Neither presented complications or residual disability. This injury has been treated with a wide range of surgical techniques, including anchor suture, pullout button sutures, screws, and plates. However, due to the difficulty in surgical fixation of fragments around finger joints, limited access to ligaments and tendons, and the lack of cases, none of the techniques have turned out as a clear option above others. Hook plates placed in distal phalanx emerge as surgical treatment for FDP avulsion types II and III in flexor zone 1, with excellent clinical outcomes.
屈指深肌（FDP）Ⅱ型和Ⅲ型撕脱骨折，也称泽西指，发生在屈指区 1 时是一种需要手术治疗的罕见疾病。本研究旨在评估钩钢板是否是修复 FDP 撕脱Ⅱ型和Ⅲ型的一种可行且可靠的选择。在 2018 年 7 月至 8 月期间，我们使用 Medartis Aptus Hand 固定系统中包含的钩钢板和 1.2×7mm 螺钉治疗了 2 例连续的屈指区 1 Leddy-Packer Ⅱ型和Ⅲ型 FDP 损伤患者，患者分别为 37 岁和 39 岁，一男一女。在随访结束时，我们评估了视觉模拟评分、活动范围、握力和上肢残疾问卷。两名患者均完成了 12 个月的随访，功能和影像学结果均良好。均未出现并发症或残留残疾。这种损伤已经采用了多种手术技术进行治疗，包括锚缝线、抽出按钮缝线、螺钉和钢板。然而，由于手指关节周围骨块的固定困难、韧带和肌腱的操作受限以及病例数量有限，没有一种技术比其他技术更具优势。钩钢板固定在远节指骨上，是治疗屈指区 1 内 FDP 撕脱Ⅱ型和Ⅲ型的一种有效手术方法，具有良好的临床效果。
