Lauge-Hansen自体与Danis-Webe自体为最常见的踝肌腱膝盖自体，在对下胸骨撒肌腱破损的个人兴趣意义上，旋后外旋II°膝盖通常认为更名下胸骨撒前肌腱的破损，下胸骨撒为首趋于稳定，确实无需下胸骨撒为首螺钉固定。而Danis-Weber B型膝盖界定为膝盖位处下胸骨撒为首水平，确实更名下胸骨撒为首破损。
由此可发现，对Danis-Weber B型膝盖，如何审核下胸骨撒有无破损，以及术前审核应该需外科手术固定下胸骨撒为首，仍无必要参看。
对此，国外学者研究了Danis-Weber B型外侧膝盖本站的方位，借此对比不同类型B型膝盖下胸骨撒为首破损比事例应该存在差异，并个人兴趣外科手术干预。
Objective（目的）确认术前X本站检查能否预测下胸骨撒为首破损机率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病事例）回顾了548事例 OTA/AO 44-B2.1型病征，287事例病征纳入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]图1 病事例纳入流程。
Main outcome measures（主要结局举例来说）踝肌腱影像片主要用途明确外侧膝盖块的远距覆盖范围。下胸骨撒为首破损界定为术中压力实验证实并需要下胸骨撒固定。
[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.]图2 Danis-Weber B型膝盖，根据外侧膝盖块远达距方位西区外。1区外界定为膝盖块远达距位处腱远距肌腱面平面以下；2区外为位处腱远距骺本站断开瘢痕与远距肌腱面彼此在在；3区外为骺本站断开瘢痕以上。
图3 西区外示意图。
Results（结果）一共191事例1区外(延至于腱远距肌腱平面左侧)破损，57两处2区外(延至于腱远距骨骺本站断开瘢痕和腱远距肌腱面彼此在在)破损，39两处3区外(延至于腱远距骨骺本站断开瘢痕以上)破损。其中，17% (33名病征)的1区外、42% (24名病征)的2区外和74% (29名病征)的3区外膝盖更名下胸骨撒肌腱破损。
2区外与1区外相对来说，肌腱为首破损的相对风险为2.4 (P，0.001)，3区外与1区外相对来说为4.3 (P，0.001)，3区外与2区外相对来说为1.8 (P = 0.002)。假定在在和假定内的性能非常好(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 三组病征下胸骨撒为首破损频发率。Conclusion（结论）OTA/AO 44-B2.1膝盖具有不同的下胸骨撒为首破损率。Weber B型膝盖频发在腱远距肌腱平面和骺本站断开疤痕彼此在在(2区外)，与频发在肌腱面左侧(1区外)的膝盖相对来说，频发肌腱破损的确实性高2.4倍。这种确实性在骺本站断开疤痕上方(3区外)的破损中更大。
OTA/AO 44-B2.1膝盖的简单分类无疑着肌腱破损，确实有利于术前咨询和外科手术计划制定。
[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
