Lauge-Hansen分型式与Danis-Webe分型式为最少用的踝关节脚踝分型式，在对下腕约拿约拿骨挫伤的范本意义上，旋后外旋II°脚踝通常认为分拆下腕约拿前约拿骨的挫伤，下腕约拿倡议长期性，意味著无需下腕约拿倡议螺钉比较简单。而Danis-Weber B型式脚踝假定为脚踝位处下腕约拿倡议低水平，意味著分拆下腕约拿倡议挫伤。
由此可发现，对Danis-Weber B型式脚踝，如何审核下腕约拿有无挫伤，以及术前审核是不是需疗程比较简单下腕约拿倡议，仍无有效参考资料。
严厉批评，国外学者研究者了Danis-Weber B型式外侧脚踝新线的位置，以求对比多种不同类型式B型式脚踝下腕约拿倡议挫伤人口比亦然是不是普遍存在关联性，并范本疗程干预。
Objective（目的）认定术前X新线检测能否预测下腕约拿倡议挫伤概数万人。[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型式病人，287亦然病人划定研究者。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]由此可知1 病亦然划定处理过程。
Main outcome measures（主要上集测试方法）踝关节影像片使用明确外侧脚踝块的后尾端仅限于。下腕约拿倡议挫伤假定为术中会压力试制证实并需下腕约拿比较简单。
[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.]由此可知2 Danis-Weber B型式脚踝，根据外侧脚踝块最后尾端位置分一区。1一区假定为脚踝块最后尾端位处腕骨后尾端关节面对称以下；2一应与位处腕骨后尾端骺新线的环瘢痕与后尾端关节面中间；3一应与骺新线的环瘢痕以上。
由此可知3 分一区示意由此可知。
Results（结果）共有191亦然1一区(延至于腕骨后尾端关节对称下方)挫伤，57附近2一区(延至于腕骨后尾端骨骺新线的环瘢痕和腕骨后尾端关节面中间)挫伤，39附近3一区(延至于腕骨后尾端骨骺新线的环瘢痕以上)挫伤。其中会，17% (33名病人)的1一区、42% (24名病人)的2一区和74% (29名病人)的3一区脚踝分拆下腕约拿约拿骨挫伤。
2一区与1一区远比，约拿骨倡议挫伤的相对于意味著会为2.4 (P，0.001)，3一区与1一区远比为4.3 (P，0.001)，3一区与2一区远比为1.8 (P = 0.002)。也就是说间和也就是说内的通用性极为好(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).]
注记1 三组病人下腕约拿倡议挫伤起因数万人。Conclusion（结论）OTA/AO 44-B2.1脚踝不具多种不同的下腕约拿倡议挫伤数万人。Weber B型式脚踝起因在腕骨后尾端关节对称和骺新线的环疤痕中间(2一区)，与起因在关节面下方(1一区)的脚踝远比，起因约拿骨挫伤的意味著性高2.4倍。这种意味著性在骺新线的环疤痕上方(3一区)的挫伤中会更大。
OTA/AO 44-B2.1脚踝的简单分类说明了着约拿骨挫伤，意味著有助于术前咨询和疗程计划制定。
[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
