To explore the clinical efficacy and safety of Kirschner wires (KWs) as a blocking screw technique for extra-articular fractures of the distal tibia treated with intramedullary nails (IMNs).
Fifty-three patients were treated with KW-assisted IMN for extra-articular fractures of the distal tibia via the blocking screw technique or Poller screw (PS) technique. The operation time, number of fluoroscopies, number of blocking screws used, blood loss and time to union were compared between the two groups. Additionally, the functional outcomes of the two groups were compared using range of motion (ROM), visual analog scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS), and Lysholm scores.
Compared with those in the PS group, the operation time in the KW group was significantly shorter, and the number of fluoroscopy procedures and amount of blood loss during KW surgery were also significantly lower ( = 0.014, 0.001, and 0.036, respectively). Regarding the functional outcomes, there were no significant differences in the ROM, VAS score, AOFAS score or Lysholm score between the two groups ( > 0.05).
In the treatment of extra-articular fractures of the distal tibia with nails, the use of KW as a blocking screw technique is safe and reliable.
探讨克氏针（KWs）作为髓内钉（IMNs）治疗胫骨远端关节外骨折的阻挡螺钉技术的临床疗效和安全性。
53例患者采用KW辅助IMN通过阻挡螺钉技术或Poller螺钉（PS）技术治疗胫骨远端关节外骨折。比较两组的手术时间、透视次数、使用的阻挡螺钉数量、失血量和愈合时间。此外，使用活动范围（ROM）、视觉模拟评分（VAS）、美国矫形足踝协会（AOFAS）和Lysholm评分比较两组的功能结果。
与PS组相比，KW组的手术时间明显缩短，KW手术期间的透视次数和失血量也明显减少（分别为=0.014、0.001和0.036）。关于功能结果，两组之间的ROM、VAS评分、AOFAS评分或Lysholm评分无显著差异（>0.05）。
在使用髓内钉治疗胫骨远端关节外骨折时，使用KW作为阻挡螺钉技术是安全可靠的。
