The 3.5 mm diameter or thicker Steinmann pins were commonly used in skeletal traction, which are so highly invasive that may result in severe complications such as pin tract infection and iatrogenic calcaneus fractures. Accordingly, Xirui Wu designed a new type of tension traction bow that can be assembled with 2.0 mm diameter Kirschner wires, but its effectiveness is unclear. We aim to evaluate the effectiveness of 2.0 mm diameter Kirschner wires assembled with Wu's Tension Traction Bows in calcaneal skeletal traction. Data of 65 patients who were admitted to our department with tibia fractures from January 2021 to June 2022 and underwent preoperative calcaneal skeletal traction were collected retrospectively. 36 patients treated with 2.0 mm diameter Kirschner wires assembled with Wu's Tension Traction Bows were assigned into Group 1, and 29 patients treated with 3.5 mm diameter Steinmann pins assembled with Bohler's traction bows were assigned into Group 2. Pins loosening, breakage, and calcaneus fractures occurred in neither group. No statistical differences were observed in traction weight, swelling reduction efficacy, and traction duration (P > 0.05). Statistically significant differences were found between the two groups in term of post-traction bleeding incidence, average bleeding duration, and mean size and healing time of traction wounds (P < 0.05). Though VAS pain score before traction and on the first two days after traction in Group 1 didn't differ from Group 2 (P > 0.05), it was significantly lower in Group 1 compared to Group 2 on the third day after traction (P = 0.030). This study demonstrates that 2.0 mm diameter Kirschner wires assembled with Wu's Tension Traction Bows produce satisfied traction outcomes with less invasion and are recommended in calcaneal skeletal traction.
直径 3.5 毫米或更粗的斯氏针常用于骨骼牵引，其具有很强的侵入性，可能导致严重的并发症，如针道感染和医源性跟骨骨折。因此，吴希瑞设计了一种新型的张力牵引弓，可与 2.0 毫米直径的克氏针组装，但效果尚不清楚。我们旨在评估用吴希瑞张力牵引弓组装的 2.0 毫米直径克氏针在跟骨骨骼牵引中的效果。回顾性收集了 2021 年 1 月至 2022 年 6 月我院收治的 65 例胫骨骨折患者术前跟骨骨骼牵引的资料。36 例患者采用 2.0 毫米直径克氏针吴希瑞张力牵引弓治疗（A 组），29 例患者采用 3.5 毫米直径斯氏针博勒氏牵引弓治疗（B 组）。两组均未发生针松动、断裂和跟骨骨折。两组牵引重量、消肿效果和牵引时间差异无统计学意义（P>0.05）。两组在牵引后出血发生率、平均出血持续时间、牵引伤口平均大小和愈合时间方面差异有统计学意义（P<0.05）。A 组患者在牵引前和牵引后前两天的 VAS 疼痛评分与 B 组无差异（P>0.05），但在牵引后第三天明显低于 B 组（P=0.030）。本研究表明，用吴希瑞张力牵引弓组装的 2.0 毫米直径克氏针牵引效果满意，侵袭性小，推荐用于跟骨骨骼牵引。
