Abstract

Objective The purpose of this study was to evaluate the use of intraoperative skeletal traction for the surgical repair of pelvic fractures. Opposition and anchorage points for the application of traction were the same in all cadavers.

Materials and Methods Cadavers from 10 adult dogs with a median body weight of 31.9 kg (range: 20–38 kg) were used. The fractures were experimentally created in all dogs to produce an oblique iliac fracture on the left side and a transverse fracture on the right (total of 20 fractures) at the same time. Dogs were positioned on an operating table in lateral recumbency and traction was applied first on the left side and then on the right after changing the position of the animal. Increasing amounts of traction were applied to each fracture and recorded until a distraction length of 2 cm was created between the bone fragments. The Kolmogorov–Smirnov test confirmed normality of the data, and a paired t-test was used to compare traction of the two fracture types.

Results The measurement of traction and distraction of the bone fragments was possible in all fractures. A distraction of at least 2 cm was obtained with a mean peak traction force of 15.4 kg for transverse fractures and 18.6 kg for oblique fractures.

Conclusion Intraoperative skeletal traction provides a useful and reliable tool for the reduction in experimental oblique and transverse iliac fractures in dogs. There were strong correlations between body weight and the force required to obtain a distraction length of 2 cm in the fracture line; for oblique fractures, traction was related to the square of body weight, and for transverse fractures, the relationship between weight and required traction was near linear.

术中骨牵引修复骨盆骨折的实验性尸体研究

摘要

目的 本研究的目的是评估术中骨骼牵引在骨盆骨折手术修复中的应用。在所有尸体中，施加牵引力的对立点和锚固点都是相同的。

材料和方法 使用 来自 10 只成年犬的尸体，平均体重为 31.9 公斤（范围：20-38 公斤）。在所有狗身上实验性地制造骨折，同时在左侧产生斜位髂骨骨折和在右侧产生横向骨折（总共 20 处骨折）。将狗以侧卧位放置在手术台上，首先在左侧施加牵引力，然后在改变动物的位置后在右侧施加牵引力。对每个骨折施加越来越多的牵引力并记录，直到在骨碎片之间产生 2 厘米的牵引长度。Kolmogorov-Smirnov 检验证实了数据的正态性，并使用配对t检验来比较两种骨折类型的牵引力。

结果 在所有骨折中都可以测量骨碎片的牵引力和牵引力。获得至少 2 厘米的牵引力，横向骨折的平均峰值牵引力为 15.4 公斤，斜向骨折的平均牵引力为 18.6 公斤。

结论 术中骨骼牵引为减少犬实验性髂骨斜骨折和横向骨折提供了有用且可靠的工具。体重与在骨折线上获得 2 cm 的牵引长度所需的力之间存在很强的相关性；对于斜向骨折，牵引力与体重的平方有关，对于横向骨折，重量与所需牵引力之间的关系接近线性。
