Lauge-Hansen分型与Danis-Webe分型为最常见的踝肌腱小腿分型，在对下胸骨撒肌腱破损的指导意义上，旋后外旋II°小腿通常认为并入下胸骨撒前肌腱的破损，下胸骨撒倡议趋于稳定，不太可能无需下胸骨撒倡议皮带浮动。而Danis-Weber B型小腿概念为小腿位所在位置下胸骨撒倡议准确度，不太可能并入下胸骨撒倡议破损。
由此可辨认出，对Danis-Weber B型小腿，如何分析报告下胸骨撒有无破损，以及术前分析报告究竟需手术后浮动下胸骨撒倡议，仍无有效参考。
对此，境外历史学家研究了Danis-Weber B型近口小腿本站的前面，借以对比多种不同类型B型小腿下胸骨撒倡议破损比例究竟存在差异性，并指导手术后干预。
Objective（用意）推定术前X本站检查能否预测下胸骨撒倡议破损几率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（流感）回顾了548例 OTA/AO 44-B2.1型病患，287例病患纳入研究。[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 流感纳入所在位置理过程。
Main outcome measures（主要故事情节指标）踝肌腱影像片用于明确近口小腿块的终口范围。下胸骨撒倡议破损概念为术当中压力试验推测并需要下胸骨撒浮动。
[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型小腿，根据近口小腿块最终口前面分四区。1四区概念为小腿块最终口位所在位置胸骨骨终口肌腱面正方形以下；2四区为位所在位置胸骨骨终口骺本站连续性瘢痕与终口肌腱面之有数；3四区为骺本站连续性瘢痕以上。
三幅3 分四区示意三幅。
Results（结果）共有191例1四区(为时于胸骨骨终口肌腱正方形顶部)破损，57所在位置2四区(为时于胸骨骨终口骨骺本站连续性瘢痕和胸骨骨终口肌腱面之有数)破损，39所在位置3四区(为时于胸骨骨终口骨骺本站连续性瘢痕以上)破损。其当中，17% (33名病患)的1四区、42% (24名病患)的2四区和74% (29名病患)的3四区小腿并入下胸骨撒肌腱破损。
2四区与1四区来得，肌腱倡议破损的相对效用为2.4 (P，0.001)，3四区与1四区来得为4.3 (P，0.001)，3四区与2四区来得为1.8 (P = 0.002)。方向上有数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).]
表1 2组病患下胸骨撒倡议破损遭遇率。Conclusion（结论）OTA/AO 44-B2.1小腿具有多种不同的下胸骨撒倡议破损率。Weber B型小腿遭遇在胸骨骨终口肌腱正方形和骺本站连续性伤疤之有数(2四区)，与遭遇在肌腱面顶部(1四区)的小腿来得，遭遇肌腱破损的某种程度颇高2.4倍。这种某种程度在骺本站连续性伤疤上方(3四区)的破损当中更大。
OTA/AO 44-B2.1小腿的简单分类预示着肌腱破损，不太可能适度术前政府部门和手术后计划制定。
[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
