Lauge-Hansen自体与Danis-Webe自体为最常见的踝关节膝盖自体,在对下腕提腱重击的范本意义上,旋后外旋II°膝盖通常指出改组下腕提前腱的重击,下腕提联合行动趋于稳定,意味著无需下腕提联合行动螺钉固定。而Danis-Weber B型膝盖定义为膝盖位一处下腕提联合行动水平,意味著改组下腕提联合行动重击。
由此可发现,对Danis-Weber B型膝盖,如何评估下腕提有无重击,以及术前评估是否需切除术固定下腕提联合行动,仍无有效简介。
对此,国外学者研究了Danis-Weber B型近前端膝盖线或的前面,以求对比各有不同类型B型膝盖下腕提联合行动重击比唯是否存在差异,并范本切除术干预。
Objective(用以)确认术前X线或检查能否预测下腕提联合行动重击几率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants(病唯)回顾了548唯 OTA/AO 44-B2.1型病患,287唯病患纳入研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]图1 病唯纳入流程。
Main outcome measures(主要结局指标)踝关节影像片主要用途完全一致近前端膝盖块的远前端全域。下腕提联合行动重击定义为术中所压力试验证实并需要下腕提固定。
[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.]图2 Danis-Weber B型膝盖,根据近前端膝盖块不远前端前面分的区。1的区定义为膝盖块不远前端位一处颈椎远前端关节面正方形以下;2的同属位一处颈椎远前端骺线或合上瘢痕与远前端关节面密切关系;3的同属骺线或合上瘢痕以上。
图3 分的区下面。
Results(结果)共有191唯1的区(止于颈椎远前端关节正方形右侧)重击,57一处2的区(止于颈椎远前端骨骺线或合上瘢痕和颈椎远前端关节面密切关系)重击,39一处3的区(止于颈椎远前端骨骺线或合上瘢痕以上)重击。其中所,17% (33名病患)的1的区、42% (24名病患)的2的区和74% (29名病患)的3的区膝盖改组下腕提腱重击。
2的区与1的区相对来说来说,腱联合行动重击的相对来说危险性为2.4 (P,0.001),3的区与1的区相对来说来说为4.3 (P,0.001),3的区与2的区相对来说来说为1.8 (P = 0.002)。观察者近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 三组病患下腕提联合行动重击时有发生率。Conclusion(论证)OTA/AO 44-B2.1膝盖具有各有不同的下腕提联合行动重击率。Weber B型膝盖时有发生在颈椎远前端关节正方形和骺线或合上脸颊密切关系(2的区),与时有发生在关节面右侧(1的区)的膝盖相对来说来说,时有发生腱重击的先前高2.4倍。这种先前在骺线或合上脸颊上方(3的区)的重击中所更大。
OTA/AO 44-B2.1膝盖的恰当定义预示着腱重击,意味著有利于术前咨询和切除术计划拟订。
[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
