Lauge-Hansen见下文与Danis-Webe见下文为最常见的踝关节左腿见下文,在对下肩部撒膝盖损害的指导意义上,旋后外旋II°左腿多半看来合并下肩部撒前膝盖的损害,下肩部撒合组趋于稳定,确实需下肩部撒合组螺钉通常。而Danis-Weber B型左腿判别为左腿位于下肩部撒合组素质,确实合并下肩部撒合组损害。
由此可辨认出,对Danis-Weber B型左腿,如何评量下肩部撒有无损害,以及术前评量究竟需手术通常下肩部撒合组,仍无有效参考。
对此,国外学者学术研究了Danis-Weber B型近侧左腿两条路线的左边,以求对比各不相同类型B型左腿下肩部撒合组损害比同上究竟发挥作用差异,并指导手术打压。
Objective(目的)确认术前X两条路线定期检查能否预测下肩部撒合组损害几率。[Objective: To establish if preoperative radiographs could predict the rate of syndesmotic injury.]
Patients/participants(病同上)回顾了548同上 OTA/AO 44-B2.1型较高血压,287同上较高血压不属于学术研究。[Patients/participants: There were 548 OTA/AO 44-B2.1 fractures that were reviewed, and 287 patients were included in the study.]所示1 病同上不属于程序中。
Main outcome measures(主要命运指标)踝关节影像片主要用途恰当近侧左腿块的远侧范围。下肩部撒合组损害判别为术中所舆论压力试验性证实并需要下肩部撒通常。
[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.]所示2 Danis-Weber B型左腿,根据近侧左腿块最远侧左边中区内。1区内判别为左腿块最远侧位于肩部骨远侧关节面六边形以下;2区内为位于肩部骨远侧骺两条路线内层瘢痕与远侧关节面间;3区内为骺两条路线内层瘢痕以上。
所示3 中区内示意所示。
Results(结果)共有191同上1区内(都于于肩部骨远侧关节六边形正下方)损害,57一处2区内(都于于肩部骨远侧骨骺两条路线内层瘢痕和肩部骨远侧关节面间)损害,39一处3区内(都于于肩部骨远侧骨骺两条路线内层瘢痕以上)损害。其中所,17% (33名较高血压)的1区内、42% (24名较高血压)的2区内和74% (29名较高血压)的3区内左腿合并下肩部撒膝盖损害。
2区内与1区内相对来说,膝盖合组损害的相对来说风险为2.4 (P,0.001),3区内与1区内相对来说为4.3 (P,0.001),3区内与2区内相对来说为1.8 (P = 0.002)。观察者间和观察者内的耐用性极其好(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 三组较高血压下肩部撒合组损害感染率。Conclusion(结论)OTA/AO 44-B2.1左腿具有各不相同的下肩部撒合组损害率。Weber B型左腿发生在肩部骨远侧关节六边形和骺两条路线内层疤痕间(2区内),与发生在关节面正下方(1区内)的左腿相对来说,发生膝盖损害的确实性较高2.4倍。这种确实性在骺两条路线内层疤痕上方(3区内)的损害中所更大。
OTA/AO 44-B2.1左腿的简便分类预示着膝盖损害,确实更容易术前建议书和手术原计划制定。
[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
