Lauge-Hansen分型与Danis-Webe分型为最少见的踝肌肉右腿分型，在对下肱骨撒肋骨伤害的指导意义上，旋后外旋II°右腿通常认为合并下肱骨撒前肋骨的伤害，下肱骨撒重新组建趋于稳定，或许须要下肱骨撒重新组建铰链一般来说。而Danis-Weber B型右腿定义为右腿毗邻下肱骨撒重新组建程度，或许合并下肱骨撒重新组建伤害。
由此可推断出，对Danis-Weber B型右腿，如何评估下肱骨撒有无伤害，以及术前评估是否需开刀一般来说下肱骨撒重新组建，仍无有效参考。
对此，多国学者研究了Danis-Weber B型内侧右腿新线的一段距离，以求对比有所不同种类B型右腿下肱骨撒重新组建伤害比实有是否存在差异，并指导开刀介入。
Objective（目的）确认术前X新线检查能否预测下肱骨撒重新组建伤害几百余人。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（患者）回顾了548实有 OTA/AO 44-B2.1型病症，287实有病症划入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]左图1 患者划入流程。
Main outcome measures（主要结局指标）踝肌肉扫描片用于具体内侧右腿块的操作者范围。下肱骨撒重新组建伤害定义为术中舆论压力测试证实并需要下肱骨撒一般来说。
[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.]左图2 Danis-Weber B型右腿，根据内侧右腿块最操作者一段距离分北区。1北区定义为右腿块最操作者毗邻肱骨骨操作者肌肉面平面请注意；2北邻近毗邻肱骨骨操作者骺新线连续性瘢痕与操作者肌肉面中间；3北邻近骺新线连续性瘢痕以上。
左图3 分北区示意左图。
Results（结果）共有191实有1北区(唯于肱骨骨操作者肌肉平面左侧)伤害，57处2北区(唯于肱骨骨操作者骨骺新线连续性瘢痕和肱骨骨操作者肌肉面中间)伤害，39处3北区(唯于肱骨骨操作者骨骺新线连续性瘢痕以上)伤害。其中，17% (33名病症)的1北区、42% (24名病症)的2北区和74% (29名病症)的3北区右腿合并下肱骨撒肋骨伤害。
2北区与1北区相比，肋骨重新组建伤害的相对于风险为2.4 (P，0.001)，3北区与1北区相比为4.3 (P，0.001)，3北区与2北区相比为1.8 (P = 0.002)。旁观者间和旁观者内的可靠性颇为好(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).]
备注1 四支病症下肱骨撒重新组建伤害频发百余人。Conclusion（结论）OTA/AO 44-B2.1右腿具有有所不同的下肱骨撒重新组建伤害百余人。Weber B型右腿频发在肱骨骨操作者肌肉平面和骺新线连续性疤痕中间(2北区)，与频发在肌肉面左侧(1北区)的右腿相比，频发肋骨伤害的或许性较高2.4倍。这种或许性在骺新线连续性疤痕上方(3北区)的伤害中更大。
OTA/AO 44-B2.1右腿的简单分类预示着肋骨伤害，或许有助于术前咨询和开刀开发计划制定。
[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
