This study describes a new technique called the "fish hook" technique for the treatment of bony mallet finger. This technique catches the dorsal fragment with a bent K-wire shaped like a fish hook. Transarticular fixation is performed with another K-wire. This technique does not directly penetrate the bone fragment to prevent fragment comminution. This study included 26 patients with mallet finger fractures who underwent surgery using the fish hook technique between 2010 and 2014. The fractures were classified according to the method of Wehbe and Schneider. The fracture fragment was fixed with a fish hook technique in all patients. The K-wire was removed after 6 weeks, when bone union was achieved. Clinical parameters, including range of motion and extensor lag, were assessed at the distal interphalangeal joint according to Crawford's criteria. The mean follow-up period was 12.8 months. Mean extensor lag was 3°, and mean range of flexion of the distal interphalangeal joint was 76°. All patients achieved bone union after 6 weeks. According to Crawford's criteria, there were 20 excellent results, 5 good results, and 1 fair result. No complications, including skin necrosis, pin loosening, and nail deformity, occurred. The fish hook technique is an effective treatment option for bony mallet finger and provides good clinical and radiologic results. [Orthopedics.2016; 39(5):295-298.].
本研究描述了一种用于治疗骨性锤状指的新技术，即“鱼钩”技术。该技术用一个弯成鱼钩形状的克氏针钩住背侧骨折块。用另一根克氏针进行经关节固定。此技术不直接穿透骨折块以防止骨折块粉碎。本研究纳入了26例锤状指骨折患者，这些患者在2010年至2014年间接受了使用鱼钩技术的手术。骨折根据韦布和施奈德的方法进行分类。所有患者均采用鱼钩技术固定骨折块。6周后当实现骨愈合时取出克氏针。根据克劳福德标准，在远侧指间关节评估包括活动范围和伸肌滞后在内的临床参数。平均随访期为12.8个月。平均伸肌滞后为3°，远侧指间关节平均屈曲范围为76°。所有患者在6周后均实现骨愈合。根据克劳福德标准，结果为优的有20例，良的有5例，可的有1例。未发生包括皮肤坏死、克氏针松动和指甲畸形在内的并发症。鱼钩技术是治疗骨性锤状指的一种有效治疗选择，并能提供良好的临床和影像学结果。[《骨科》。2016；39(5):295 - 298。]
