Lauge-Hansen的测试与Danis-Webe的测试为最常见的踝关节膝盖的测试，在对下胸骨提肋骨重击的指导意义上，旋后外旋II°膝盖通常忽视更名下胸骨提前肋骨的重击，下胸骨提建立联系有所改善，显然无需下胸骨提建立联系皮带固定。而Danis-Weber B型膝盖假定为膝盖坐落下胸骨提建立联系水平，显然更名下胸骨提建立联系重击。
由此可发现，对Danis-Weber B型膝盖，如何评估下胸骨提有无重击，以及术前评估是否需动手术固定下胸骨提建立联系，仍无合理参考。
对此，国外学者数据分析了Danis-Weber B型内侧膝盖终点站的所在位置，借此对比不同类型B型膝盖下胸骨提建立联系重击比例是否存在差异，并指导动手术干预。
Objective（目的）推定术前X终点站检查能否数据分析下胸骨提建立联系重击几叛将。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病例）回顾了548例 OTA/AO 44-B2.1型病患者，287例病患者划入数据分析。[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 病例划入流程。
Main outcome measures（主要结局指标）踝关节影像片用于明确内侧膝盖块的启动时仅限于。下胸骨提建立联系重击假定为术中压力试验证实并必需下胸骨提固定。
[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.]由此可知2 Danis-Weber B型膝盖，根据内侧膝盖块最启动时所在位置分北区。1北区假定为膝盖块最启动时坐落胸骨骨启动时关节面平面下述；2北比邻坐落胸骨骨启动时骺终点站嵌入瘢痕与启动时关节面之外；3北比邻骺终点站嵌入瘢痕以上。
由此可知3 分北区示意由此可知。
Results（结果）共有191例1北区(应于于胸骨骨启动时关节平面下方)重击，57所在所在位置2北区(应于于胸骨骨启动时骨骺终点站嵌入瘢痕和胸骨骨启动时关节面之外)重击，39所在所在位置3北区(应于于胸骨骨启动时骨骺终点站嵌入瘢痕以上)重击。其中，17% (33名病患者)的1北区、42% (24名病患者)的2北区和74% (29名病患者)的3北区膝盖更名下胸骨提肋骨重击。
2北区与1北区相较，肋骨建立联系重击的相对不确定性为2.4 (P，0.001)，3北区与1北区相较为4.3 (P，0.001)，3北区与2北区相较为1.8 (P = 0.002)。通过观察外和通过观察内的可靠度相当好(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).]
请注意1 三组病患者下胸骨提建立联系重击发生叛将。Conclusion（结论）OTA/AO 44-B2.1膝盖具有不同的下胸骨提建立联系重击叛将。Weber B型膝盖发生在胸骨骨启动时关节平面和骺终点站嵌入脸部之外(2北区)，与发生在关节面下方(1北区)的膝盖相较，发生肋骨重击的不太显然高2.4倍。这种不太显然在骺终点站嵌入脸部上端(3北区)的重击中更大。
OTA/AO 44-B2.1膝盖的直观分类法预示着肋骨重击，显然有助于术前咨询和动手术计划实施。
[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
