Lauge-Hansen种系统与Danis-Webe种系统为最少用的踝脊柱脚踝种系统，在对下肩部罗尼手肘烧伤的督导意义上，旋后外旋II°脚踝通常确信合并下肩部罗尼前手肘的烧伤，下肩部罗尼建立联系趋于稳定，不太可能无需下肩部罗尼建立联系螺丝固定。而Danis-Weber B型脚踝表述为脚踝毗邻下肩部罗尼建立联系水平，不太可能合并下肩部罗尼建立联系烧伤。
由此可注意到，对Danis-Weber B型脚踝，如何分析报告下肩部罗尼有无烧伤，以及术前分析报告前提需开刀固定下肩部罗尼建立联系，仍无有效参考。
举动，欧美史家深入研究了Danis-Weber B型近侧脚踝终点站的位置，以求对比各不相同类型B型脚踝下肩部罗尼建立联系烧伤%-前提存在差异，并督导开刀干预。
Objective（目的）确认术前X终点站检查能否预期下肩部罗尼建立联系烧伤几率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病亦然）回顾了548亦然 OTA/AO 44-B2.1型病患者，287亦然病患者扩展到深入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]三幅1 病亦然扩展到流程。
Main outcome measures（主要结局指标）踝脊柱底片片用于明确近侧脚踝块的终侧范围。下肩部罗尼建立联系烧伤表述为术中的心理压力试验性证实并需要下肩部罗尼固定。
[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.]三幅2 Danis-Weber B型脚踝，根据近侧脚踝块最终侧位置分的区。1的区表述为脚踝块最终侧毗邻肩部骨终侧脊柱面矩形都有；2的同属毗邻肩部骨终侧骺终点站连续性瘢痕与终侧脊柱面之近；3的同属骺终点站连续性瘢痕以上。
三幅3 分的区示意三幅。
Results（结果）仅有191亦然1的区(延至于肩部骨终侧脊柱矩形下方)烧伤，57处2的区(延至于肩部骨终侧骨骺终点站连续性瘢痕和肩部骨终侧脊柱面之近)烧伤，39处3的区(延至于肩部骨终侧骨骺终点站连续性瘢痕以上)烧伤。其中的，17% (33名病患者)的1的区、42% (24名病患者)的2的区和74% (29名病患者)的3的区脚踝合并下肩部罗尼手肘烧伤。
2的区与1的区相比较于，手肘建立联系烧伤的相比较风险为2.4 (P，0.001)，3的区与1的区相比较于为4.3 (P，0.001)，3的区与2的区相比较于为1.8 (P = 0.002)。也就是说近和也就是说内的可靠性非常好(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).]
表1 四支病患者下肩部罗尼建立联系烧伤愈演愈烈率。Conclusion（结论）OTA/AO 44-B2.1脚踝具有各不相同的下肩部罗尼建立联系烧伤率。Weber B型脚踝愈演愈烈在肩部骨终侧脊柱矩形和骺终点站连续性疤痕之近(2的区)，与愈演愈烈在脊柱面下方(1的区)的脚踝相比较于，愈演愈烈手肘烧伤的不太可能较低2.4倍。这种不太可能在骺终点站连续性疤痕上方(3的区)的烧伤中的更多。
OTA/AO 44-B2.1脚踝的最简单界定暗示着着手肘烧伤，不太可能有助于术前咨询和开刀原计划订定。
[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
