Lauge-Hansen分型与Danis-Webe分型为最常见于的踝手部扭伤分型，在对下突利亚半月板损坏的指导意义上，旋后外旋II°扭伤通常认为合并下突利亚前半月板的损坏，下突利亚联合行动趋于稳定，有可能无需下突利亚联合行动刀具相同。而Danis-Weber B型扭伤定义为扭伤座落下突利亚联合行动程度，有可能合并下突利亚联合行动损坏。
由此可辨认出，对Danis-Weber B型扭伤，如何指标下突利亚有无损坏，以及术前指标是否需手术相同下突利亚联合行动，仍无有效概要。
异议，国外学者研究了Danis-Weber B型近侧扭伤直通的前面，以求对比并不相同类型B型扭伤下突利亚联合行动损坏比同上是否存在差异性，并指导手术干预。
Objective（目的）确认术前X直通检查能否预测下突利亚联合行动损坏生存率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病同上）回顾了548同上 OTA/AO 44-B2.1型病症，287同上病症划定研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]右下1 病同上划定流程。
Main outcome measures（主要结局指标）踝手部影像片应用于明确近侧扭伤块的近侧范围。下突利亚联合行动损坏定义为术里面压力试验证实并需要下突利亚相同。
[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.]右下2 Danis-Weber B型扭伤，根据近侧扭伤块最近侧前面分区内。1区内定义为扭伤块最近侧座落突骨近侧手部面梯形都有；2区内为座落突骨近侧骺直通连续性瘢痕与近侧手部面之间；3区内为骺直通连续性瘢痕以上。
右下3 分区内示意右下。
Results（结果）共有191同上1区内(月终于突骨近侧手部梯形下方)损坏，57东南侧2区内(月终于突骨近侧骨骺直通连续性瘢痕和突骨近侧手部面之间)损坏，39东南侧3区内(月终于突骨近侧骨骺直通连续性瘢痕以上)损坏。其里面，17% (33名病症)的1区内、42% (24名病症)的2区内和74% (29名病症)的3区内扭伤合并下突利亚半月板损坏。
2区内与1区内相较，半月板联合行动损坏的相对风险为2.4 (P，0.001)，3区内与1区内相较为4.3 (P，0.001)，3区内与2区内相较为1.8 (P = 0.002)。观察者间和观察者内的可靠性非常好(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).]
列于1 三组病症下突利亚联合行动损坏牵涉到率。Conclusion（论据）OTA/AO 44-B2.1扭伤具有并不相同的下突利亚联合行动损坏率。Weber B型扭伤牵涉到在突骨近侧手部梯形和骺直通连续性皱纹之间(2区内)，与牵涉到在手部面下方(1区内)的扭伤相较，牵涉到半月板损坏的有可能性较高2.4倍。这种有可能性在骺直通连续性皱纹上侧(3区内)的损坏里面更大。
OTA/AO 44-B2.1扭伤的简单类群预示着半月板损坏，有可能有助于术前咨询和手术开发计划制定。
[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
