Lauge-Hansen分型与Danis-Webe分型为最常见的踝肌肉扭伤分型，在对下腕大卫肋骨损坏的指导意义上，旋后外旋II°扭伤往往显然分拆下腕大卫前肋骨的损坏，下腕大卫重新组建趋于稳定，可能不须下腕大卫重新组建箍一般来说。而Danis-Weber B型扭伤概念为扭伤毗邻下腕大卫重新组建水平，可能分拆下腕大卫重新组建损坏。
由此可发现，对Danis-Weber B型扭伤，如何评量下腕大卫有无损坏，以及术前评量是否需手术后一般来说下腕大卫重新组建，仍无有效参考。
对此，国外语言学家数据分析了Danis-Weber B型后端扭伤终点站的右方，以求对比有所不同各种类型B型扭伤下腕大卫重新组建损坏比可有是否依赖于差异，并指导手术后干预。
Objective（目的）表明术前X终点站检查能否数据分析下腕大卫重新组建损坏几率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病可有）概述了548可有 OTA/AO 44-B2.1型高血压，287可有高血压纳入数据分析。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]上图1 病可有纳入程序。
Main outcome measures（主要一集指标）踝肌肉影像片主要用途明确后端扭伤块的操作者范围。下腕大卫重新组建损坏概念为术中压力检验猜测并能够下腕大卫一般来说。
[Main outcome measures: Ankle radiographs were used to determine the zone of distal extent of the proximal fracture fragment. Syndesmotic injury was defined as positive intraoperative stress examination that required syndesmotic fixation.]上图2 Danis-Weber B型扭伤，根据后端扭伤块最操作者右方分七区。1七区概念为扭伤块最操作者毗邻腕骨操作者肌肉面对称一般而言；2七区为毗邻腕骨操作者骺终点站断开瘢痕与操作者肌肉面密切关系；3七区为骺终点站断开瘢痕以上。
上图3 分七区示意上图。
Results（结果）总计191可有1七区(起至于腕骨操作者肌肉对称下方)损坏，57东南侧2七区(起至于腕骨操作者骨骺终点站断开瘢痕和腕骨操作者肌肉面密切关系)损坏，39东南侧3七区(起至于腕骨操作者骨骺终点站断开瘢痕以上)损坏。其中，17% (33名高血压)的1七区、42% (24名高血压)的2七区和74% (29名高血压)的3七区扭伤分拆下腕大卫肋骨损坏。
2七区与1七区相对，肋骨重新组建损坏的相对风险为2.4 (P，0.001)，3七区与1七区相对为4.3 (P，0.001)，3七区与2七区相对为1.8 (P = 0.002)。方向上间和方向上内的可靠性非常好(k = 0.86，0.94)。
[Results: There were 191 zone 1 (ending below the plafond) injuries, 57 zone 2 (ending between the physeal scar and the plafond) injuries, and 39 zone 3 (ending above the physeal scar) injuries. Of these, 17% (33 patients) of zone 1, 42% (24) of zone 2, and 74% (29) of zone 3 fractures had syndesmotic injuries. The relative risk of syndesmotic injury of zone 1 compared with zone 2 was 2.4 (P , 0.001), zone 1 to zone 3 was 4.3 (P , 0.001), and zone 2 to zone 3 was 1.8 (P = 0.002). The interobserver and intraobserver reliability was excellent (k = 0.86, 0.94).]
注记1 三组高血压下腕大卫重新组建损坏引发率。Conclusion（结论）OTA/AO 44-B2.1扭伤不具备有所不同的下腕大卫重新组建损坏率。Weber B型扭伤引发在腕骨操作者肌肉对称和骺终点站断开疤痕密切关系(2七区)，与引发在肌肉面下方(1七区)的扭伤相对，引发肋骨损坏的可能性高2.4倍。这种可能性在骺终点站断开疤痕上方(3七区)的损坏中更大。
OTA/AO 44-B2.1扭伤的最简单归类预示着肋骨损坏，可能有助于术前讨论和手术后计划草拟。
[Conclusion: OTA/AO 44-B2.1 fractures he a varying rate of syndesmotic injury. Weber B fractures that end between the level of the plafond and the physeal scar (zone 2) are 2.4 times more likely to he a syndesmotic injury compared with those that end below the plafond (zone 1). This is magnified in those injuries ending above the scar (zone 3). This simple classification of OTA/AO 44-B2.1 fractures is predictive of syndesmotic injury and may aid in preoperative counseling and planning.]相关新闻
