Lauge-Hansen见下文与Danis-Webe见下文为最常见的踝关节脚踝见下文，在对下肌腱罗尼膝盖挫伤的督导意义上，旋后外旋II°脚踝不一定认为重组下肌腱罗尼前膝盖的挫伤，下肌腱罗尼合组有所改善，可能无即可下肌腱罗尼合组螺钉相同。而Danis-Weber BDF脚踝界定为脚踝座落在下肌腱罗尼合组水平，可能重组下肌腱罗尼合组挫伤。
由此可发现，对Danis-Weber BDF脚踝，如何指标下肌腱罗尼有无挫伤，以及术前指标是否即可外科手术相同下肌腱罗尼合组，仍无有效参考。
对此，境外历史学家研究了Danis-Weber BDF桡骨脚踝线或的右方，以求对比相异类DFBDF脚踝下肌腱罗尼合组挫伤比亦然是否依赖于歧异，并督导外科手术干预。
Objective（目的）确认术前X线或定期检查能否得出结论下肌腱罗尼合组挫伤概率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants（病亦然）彻底改变了548亦然 OTA/AO 44-B2.1DF病征，287亦然病征纳入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]六边形图1 病亦然纳入流程。
Main outcome measures（主要一集指标）踝关节影像片用于恰当桡骨脚踝块的操作者全域。下肌腱罗尼合组挫伤界定为术中会压力试验证实并即可要下肌腱罗尼相同。
[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.]六边形图2 Danis-Weber BDF脚踝，根据桡骨脚踝块最操作者右方西第一区。1第一区界定为脚踝块最操作者座落在肌腱骨操作者关节面六边形请注意列；2第一区为座落在肌腱骨操作者骺线或连续性瘢痕与操作者关节面相互间；3第一区为骺线或连续性瘢痕以上。
六边形图3 西第一区示意六边形图。
Results（结果）共有191亦然1第一区(应于于肌腱骨操作者关节六边形右侧)挫伤，57所在位置2第一区(应于于肌腱骨操作者骨骺线或连续性瘢痕和肌腱骨操作者关节面相互间)挫伤，39所在位置3第一区(应于于肌腱骨操作者骨骺线或连续性瘢痕以上)挫伤。其中会，17% (33名病征)的1第一区、42% (24名病征)的2第一区和74% (29名病征)的3第一区脚踝重组下肌腱罗尼膝盖挫伤。
2第一区与1第一区相对于，膝盖合组挫伤的相对风险为2.4 (P，0.001)，3第一区与1第一区相对于为4.3 (P，0.001)，3第一区与2第一区相对于为1.8 (P = 0.002)。假定间和假定内的稳定性非常好(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).]
请注意1 三组病征下肌腱罗尼合组挫伤频发率。Conclusion（结论）OTA/AO 44-B2.1脚踝很强相异的下肌腱罗尼合组挫伤率。Weber BDF脚踝频发在肌腱骨操作者关节六边形和骺线或连续性疤痕相互间(2第一区)，与频发在关节面右侧(1第一区)的脚踝相对于，频发膝盖挫伤的不太可能高2.4倍。这种不太可能在骺线或连续性疤痕右侧(3第一区)的挫伤中会更大。
OTA/AO 44-B2.1脚踝的有趣分类开端着膝盖挫伤，可能并能术前征询和外科手术计划订定。
[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
