Lauge-Hansen见下文与Danis-Webe见下文为最常见的踝肌腱右腿见下文，在对下肩胛骨约翰腱破损的指导意义上，旋后外旋II°右腿一般而言显然分割下肩胛骨约翰前腱的破损，下肩胛骨约翰牵头趋于稳定，确实无需下肩胛骨约翰牵头螺钉固定。而Danis-Weber B型右腿度量为右腿坐落于下肩胛骨约翰牵头水准，确实分割下肩胛骨约翰牵头破损。
由此可断定，对Danis-Weber B型右腿，如何危险性评估下肩胛骨约翰有无破损，以及术前危险性评估前提需手术后固定下肩胛骨约翰牵头，仍无有效参考。
对此，国外历史学家研究成果了Danis-Weber B型锁骨右腿线或的右方，求对比不同并不一定B型右腿下肩胛骨约翰牵头破损比实有前提存在差异，并指导手术后干预。
Objective（最终目标）确认术前X线或检查能否预测下肩胛骨约翰牵头破损几数万人。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（传染病）回顾了548实有 OTA/AO 44-B2.1型病变，287实有病变不属于研究成果。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]图1 传染病不属于流程。
Main outcome measures（主要结局举实有来说）踝肌腱摄影机片用作明确锁骨右腿块的控制台范围。下肩胛骨约翰牵头破损度量为术中会舆论压力试验证实并需要下肩胛骨约翰固定。
[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型右腿，根据锁骨右腿块不控制台右方分四区。1四区度量为右腿块不控制台坐落于肩胛骨骨控制台肌腱面直角一般而言；2四区为坐落于肩胛骨骨控制台骺线或嵌入瘢痕与控制台肌腱面之两者之间；3四区为骺线或嵌入瘢痕以上。
图3 分四区示意图。
Results（结果）共计191实有1四区(延至于肩胛骨骨控制台肌腱直角顶部)破损，57处2四区(延至于肩胛骨骨控制台骨骺线或嵌入瘢痕和肩胛骨骨控制台肌腱面之两者之间)破损，39处3四区(延至于肩胛骨骨控制台骨骺线或嵌入瘢痕以上)破损。其中会，17% (33名病变)的1四区、42% (24名病变)的2四区和74% (29名病变)的3四区右腿分割下肩胛骨约翰腱破损。
2四区与1四区相对于，腱牵头破损的相对危险性为2.4 (P，0.001)，3四区与1四区相对于为4.3 (P，0.001)，3四区与2四区相对于为1.8 (P = 0.002)。观察者两者之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).]
表1 2组病变下肩胛骨约翰牵头破损起因数万人。Conclusion（结论）OTA/AO 44-B2.1右腿兼具不同的下肩胛骨约翰牵头破损数万人。Weber B型右腿起因在肩胛骨骨控制台肌腱直角和骺线或嵌入伤疤之两者之间(2四区)，与起因在肌腱面顶部(1四区)的右腿相对于，起因腱破损的确实性更高2.4倍。这种确实性在骺线或嵌入伤疤上方(3四区)的破损中会较大。
OTA/AO 44-B2.1右腿的非常简单分类预示着腱破损，确实借以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
