Lauge-Hansen定期检查和与Danis-Webe定期检查和为最常见的踝关节手肘定期检查和，在对下突阿斯韧带受损的指导意义上，旋后外旋II°手肘通常忽视合并下突阿斯前韧带的受损，下突阿斯倡议保持稳定，可能无必需下突阿斯倡议螺栓一般而言。而Danis-Weber B型手肘假设为手肘位于下突阿斯倡议水平，可能合并下突阿斯倡议受损。
由此可发现，对Danis-Weber B型手肘，如何评估下突阿斯有无受损，以及术前评估是否必需动手术一般而言下突阿斯倡议，仍无必必需简介。
对此，国外学者研究了Danis-Weber B型近端手肘终点站的后方，以求对比并不相同种类B型手肘下突阿斯倡议受损比可有是否共存区内别，并指导动手术打压。
Objective（目标）确认术前X终点站定期检查能否预见下突阿斯倡议受损概赴援。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病可有）回顾了548可有 OTA/AO 44-B2.1型病变，287可有病变纳入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]示可有1 病可有纳入流程。
Main outcome measures（主要结局指标）踝关节影像片运用于完全一致近端手肘块的控制台范围。下突阿斯倡议受损假设为术中压力试验证实并必需要下突阿斯一般而言。
[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.]示可有2 Danis-Weber B型手肘，根据近端手肘块最控制台后方北区内。1区内假设为手肘块最控制台位于突骨控制台关节面平面此表；2区内为位于突骨控制台骺终点站嵌入瘢痕与控制台关节面之数间；3区内为骺终点站嵌入瘢痕以上。
示可有3 北区内示意示可有。
Results（结果）共有191可有1区内(唯于突骨控制台关节平面底部)受损，57处2区内(唯于突骨控制台骨骺终点站嵌入瘢痕和突骨控制台关节面之数间)受损，39处3区内(唯于突骨控制台骨骺终点站嵌入瘢痕以上)受损。其中，17% (33名病变)的1区内、42% (24名病变)的2区内和74% (29名病变)的3区内手肘合并下突阿斯韧带受损。
2区内与1区内相较，韧带倡议受损的相对后果为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)。旁观者数间和旁观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 三组病变下突阿斯倡议受损起因赴援。Conclusion（结论）OTA/AO 44-B2.1手肘较强并不相同的下突阿斯倡议受损赴援。Weber B型手肘起因在突骨控制台关节平面和骺终点站嵌入左眼之数间(2区内)，与起因在关节面底部(1区内)的手肘相较，起因韧带受损的必要性高2.4倍。这种必要性在骺终点站嵌入左眼底部(3区内)的受损中更大。
OTA/AO 44-B2.1手肘的非常简单分类预示着韧带受损，可能更进一步术前咨询和动手术原计划订定。
[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
